I'm a bug lover, myself --
0
0
2000
我是虫子的爱好者，
00:17
not from childhood, by the way,
1
2000
2000
不过并不是从小就这样，
00:19
but rather late.
2
4000
2000
是年纪较大以后才开始的。
00:21
When I bachelored,
3
6000
2000
在大学时期，
00:23
majoring in zoology in Tel Aviv University,
4
8000
3000
我在特拉维夫大学主修动物学，
00:26
I kind of fell in love with bugs.
5
11000
2000
我开始对虫子产生兴趣。
00:28
And then, within zoology,
6
13000
2000
于是，在动物学系里，
00:30
I took the course or the discipline of entomology,
7
15000
3000
我选修了昆虫学的相关课程，
00:33
the science of insects.
8
18000
3000
昆虫科学这门课。
00:36
And then I thought, myself, how can I be practical
9
21000
3000
当时我想着，我要怎么去运用它
00:39
or help in the science of entomology?
10
24000
3000
或是我该如何对昆虫科学有所贡献?
00:42
And then I moved to the world of plant protection --
11
27000
3000
接着我开始往保护植物的方向探索
00:45
plant protection from insects,
12
30000
3000
保护植物不被昆虫侵害，
00:48
from bad bugs.
13
33000
2000
被那些害虫所侵害。
00:50
And then within plant protection,
14
35000
2000
在保护植物这方面，
00:52
I came into the discipline
15
37000
2000
我开始接触
00:54
of biological pest control
16
39000
2000
生物抑制害虫法，
00:56
which we actually define
17
41000
2000
我们对这方法的定义是
00:58
as the use of living organisms
18
43000
3000
利用活着的有机生物
01:01
to reduce populations
19
46000
2000
来降低对于植物有害的
01:03
of noxious plant pests.
20
48000
3000
那些害虫数量。
01:06
So it's a whole discipline in plant protection
21
51000
3000
在于植物保护上来说，
01:09
that's aiming at the reduction of chemicals.
22
54000
3000
这种方式的目标是降低化学药剂的使用量。
01:13
And biological pest control, by the way,
23
58000
2000
这种生物抑制害虫法，
01:15
or these good bugs that we are talking about,
24
60000
3000
或是我们所谈的这种益虫，
01:18
they've existed in the world for thousands and thousands of years,
25
63000
3000
它们已经存在这世上好几千年了，
01:21
for a long, long time.
26
66000
2000
已经很久很久了。
01:23
But only in the last 120 years
27
68000
3000
但是直到近120年来
01:26
people started,
28
71000
3000
人们才逐渐开始知道，
01:29
or people knew more and more how to exploit, or how to use,
29
74000
3000
如何去开发、利用它们，
01:32
this biological control phenomenon,
30
77000
3000
以及如何去使用这种生物抑制害虫法，
01:35
or in fact, natural control phenomenon,
31
80000
3000
或者该说，自然抑制法，
01:38
to their own needs.
32
83000
3000
来达到人们的目的。
01:41
Because biological control phenomenon,
33
86000
2000
因为生物抑制害虫法
01:43
you can see it in your backyard.
34
88000
2000
它就存在于你的后院里面。
01:45
Just take a magnifying glass. You see what I have here?
35
90000
2000
只要拿个放大镜。你看我拿的这个是什么？
01:47
That's a magnifier times 10.
36
92000
2000
这是一个十倍的放大镜。
01:49
Yeah, times 10.
37
94000
2000
对，十倍而已。
01:51
Just open it.
38
96000
2000
只用它。
01:53
You just twist leaves, and you see a whole new world
39
98000
3000
你只要把叶子翻开来，你就会发现一个新世界，
01:56
of minute insects,
40
101000
2000
那里有着微小的昆虫，
01:58
or little spiders of one millimeter, one and a half,
41
103000
3000
长度只有1毫米,1.5毫米
02:01
two millimeters long,
42
106000
2000
或是2毫米大小的蜘蛛，
02:03
and you can distinguish between the good ones and the bad ones.
43
108000
3000
你可以去分辨益虫和害虫。
02:06
So this phenomenon of natural control
44
111000
2000
所以这种自然的抑制方式
02:08
exists literally everywhere.
45
113000
2000
确实在每个地方存在着。
02:10
Here, in front of this building, I'm sure.
46
115000
2000
我敢肯定这栋建筑物的前面就有。
02:12
Just have a look at the plants.
47
117000
2000
看看这些植物。
02:14
So it's everywhere,
48
119000
2000
到处都是昆虫，
02:16
and we need to know how to exploit it.
49
121000
3000
我们需要知道怎么去发现它。
02:19
Well let us go hand by hand
50
124000
2000
好，让我们一样样来看，
02:21
and browse through just a few examples.
51
126000
3000
看看后面这些例子。
02:24
What is a pest?
52
129000
2000
什么是害虫?
02:26
What damage [does] it actually inflict on the plant?
53
131000
3000
它会对植物产生什么样的害处?
02:29
And what is the natural enemy,
54
134000
2000
还有它的天敌是什么呢?
02:31
the biologically controlled agent,
55
136000
2000
生物抑制害虫的媒介，
02:33
or the good bug, that we are talking about?
56
138000
2000
或是我们所提到的益虫?
02:35
In general, I'm going to talk
57
140000
2000
大致上来说，我要谈的
02:37
about insects and spiders,
58
142000
3000
是昆虫和蜘蛛，
02:40
or mites, let us call them.
59
145000
3000
或是螨，我们这样称呼它好了。
02:43
Insects, those six-legged organisms
60
148000
2000
昆虫 -- 是那些有六只脚的有机生物，
02:45
and spiders or mites,
61
150000
2000
而蜘蛛或螨，
02:47
the eight-legged organisms.
62
152000
2000
它们是八只脚的有机生物。
02:49
Let's have a look at that.
63
154000
2000
我们看看这个。
02:51
Here is a pest, devastating pest, a spider mite,
64
156000
3000
这是一只害虫，会搞破坏的害虫，一只蜘蛛螨，
02:54
because it does a lot of webbing like a spider.
65
159000
3000
因为它像蜘蛛一样会产生许多网状的东西。
02:57
You see the mother in between
66
162000
2000
你看中间的那只是妈妈
02:59
and two daughters, probably on the left and right,
67
164000
2000
还有左右两边那大概是两个女儿，
03:01
and a single egg on the right-hand side.
68
166000
3000
右手边还有一个蛋。
03:04
And then you see what kind of damage it can inflict.
69
169000
2000
接下来你可以知道它所造成的损害是什么。
03:06
On your right-hand side you can see a cucumber leaf,
70
171000
2000
右手边你可以看见黄瓜的叶子，
03:08
and on the middle, cotton leaf,
71
173000
2000
中间是棉花的叶子，
03:10
and on the left a tomato leaf with these little stipplings.
72
175000
3000
左边是蕃茄的叶子连着一些小叶子
03:13
They can literally turn from green to white
73
178000
3000
这些蜘蛛利用尖嘴刺穿叶子，
03:16
because of the sucking, piercing
74
181000
2000
吸食汁液之后，
03:18
mouthparts
75
183000
2000
让这些叶子
03:20
of those spiders.
76
185000
2000
由绿色转变成白色。
03:22
But here comes nature
77
187000
2000
但接下来的是大自然
03:24
that provides us with a good spider.
78
189000
2000
提供我们的益虫蜘蛛。
03:26
This is a predatory mite -- just as small as a spider mite, by the way,
79
191000
3000
这是一只掠食性螨-- 和蜘蛛螨一样小，
03:29
one millimeter, two millimeters long, not more than that,
80
194000
3000
1毫米到2毫米左右的长度，
03:32
running quickly, hunting,
81
197000
3000
跑得很快，能猎食，
03:35
chasing the spider mites.
82
200000
2000
追逐着蜘蛛螨。
03:37
And here you can see this lady in action
83
202000
2000
你可以看见左手边这位女士
03:39
on your left-hand side --
84
204000
2000
正在用餐 --
03:41
just pierces, sucks
85
206000
2000
刺穿过左边那只蜘蛛螨的身体，
03:43
the body fluids on the left-hand side of the pest mite.
86
208000
3000
吸食着它的体液。
03:46
And after five minutes, this is what you see:
87
211000
3000
大概五分钟过后，结果如你所见，
03:49
just a typical dead corpse,
88
214000
2000
只剩下一具典型的尸体 --
03:51
shriveled, sucked-out,
89
216000
2000
充满皱折，已经被吸干的
03:53
dead corpse of the spider mite,
90
218000
2000
蜘蛛螨的尸体，
03:55
and next to it, two satiated individuals
91
220000
2000
在旁边的，则是两只
03:57
of predatory mites,
92
222000
2000
吃饱喝足的掠食螨，
03:59
a mother on the left-hand side,
93
224000
2000
左手边的是妈妈，
04:01
a young nymph on the right-hand side.
94
226000
2000
右手边的是一个小姑娘。
04:03
By the way, a meal for them for 24 hours
95
228000
3000
对了，对它们来说，
04:06
is about five individuals
96
231000
2000
一天24小时的食物，
04:08
of the spider mites, of the bad mites,
97
233000
3000
大概是5只蜘蛛螨，或是那些害虫螨，
04:11
or 15 to 20 eggs
98
236000
2000
或是15到20只
04:13
of the pest mites.
99
238000
2000
害虫螨的蛋。
04:15
By the way, they are hungry always.
100
240000
3000
换句话说，它们一直都很饿。
04:18
(Laughter)
101
243000
2000
(笑声)
04:20
And there is another example: aphids.
102
245000
2000
这是另一个例子：蚜虫。
04:22
By the way, it's springtime now in Israel.
103
247000
2000
对了，现在在以色列正值春天，
04:24
When temperature rises sharply,
104
249000
3000
温度正快速在上升。
04:27
you can see those bad ones, those aphids, all over the plants,
105
252000
3000
你可以看见那些有害的蚜虫，在植物上到处都是，
04:30
in your hibiscus, in your lantana,
106
255000
3000
在山芙蓉上，在马缨丹上，
04:33
in the young, fresh foliage
107
258000
2000
在那些被称为春芽的
04:35
of the spring flush, so-called.
108
260000
2000
刚长出来的嫩叶上。
04:37
By the way, with aphids you have only females,
109
262000
2000
对了，那些蚜虫，只有母蚜虫
04:39
like Amazons.
110
264000
2000
就像亚马逊一族一样。
04:41
Females giving rise to females giving rise to other females.
111
266000
3000
母的生母的，然后再生出母的。
04:44
No males at all.
112
269000
2000
完全没有公的。
04:46
Parthenogenesis, [as it] was so called.
113
271000
2000
这被称为单性生殖。
04:48
And they are very happy with that, apparently.
114
273000
3000
看起来它们对此还挺开心的。
04:51
Here we can see the damage.
115
276000
2000
接下来我们可以看见它所造成的伤害。
04:53
Those aphids secrete
116
278000
2000
这些蚜虫会分泌
04:55
some sticky, sugary liquid
117
280000
3000
一些黏稠的，甜甜的液体，
04:58
called honeydew,
118
283000
2000
称作为蜜汁。
05:00
and this just globs
119
285000
2000
这些会在植物的上面
05:02
the upper parts of the plant.
120
287000
2000
形成小水珠的形状。
05:04
Here you see a typical cucumber leaf
121
289000
2000
你可以看见典型的黄瓜叶子
05:06
that turned actually from green to black
122
291000
2000
因为覆盖在上面的黑色真菌
05:08
because of a black fungus, sooty mold,
123
293000
2000
以及乌黑的霉菌
05:10
which is covering it.
124
295000
2000
让它从绿色变成了黑色。
05:12
And here comes the salvation
125
297000
3000
接下来拯救者上场了，
05:15
through this parasitic wasp.
126
300000
3000
就是这个寄生的胡蜂。
05:18
Here we are not talking about a predator.
127
303000
2000
这儿我们说的不是掠食者。
05:20
Here we are talking a parasite --
128
305000
2000
我们说的是寄生者，
05:22
not a two-legged parasite,
129
307000
2000
并不是两只脚的寄生者，
05:24
but an eight-legged parasite, of course.
130
309000
3000
而是六只脚的寄生者。
05:27
This is a parasitic wasp,
131
312000
2000
这是寄生胡蜂，
05:29
again, two millimeters long, slender,
132
314000
2000
大概2毫米长，相当纤细，
05:31
a very quick
133
316000
2000
它是一种行动迅速
05:33
and sharp flier.
134
318000
2000
相当机警的飞行者。
05:35
And here you can see this parasite in action,
135
320000
2000
这边你可以看见寄生的过程，
05:37
like in an acrobatic maneuver.
136
322000
3000
就像是在做特技表演一样。
05:40
She stands vis-a-vis
137
325000
2000
它正面对面
05:42
in front of the victim at the right-hand side,
138
327000
2000
从右手边直接挡在对手的面前，
05:44
bending its abdomen
139
329000
2000
弯起它的腹部
05:46
and inserting a single egg,
140
331000
2000
将一个蛋放进宿主体内，
05:48
a single egg into the body fluids
141
333000
2000
一个蛋进入了
05:50
of the aphid.
142
335000
2000
蚜虫的体液之中。
05:52
By the way, the aphid tries to escape.
143
337000
3000
对了，这只蚜虫试图要逃脱。
05:55
She kicks and bites
144
340000
2000
它乱踢乱咬，
05:57
and secretes different liquids,
145
342000
2000
分泌不同的液体，
05:59
but nothing will happen, in fact.
146
344000
2000
不过结果都没有用。
06:01
Only the egg of the parasite
147
346000
2000
寄生者只会放一个蛋
06:03
will be inserted into the body fluids of the aphid.
148
348000
3000
在蚜虫的体液之中。
06:06
And after a few days, depending upon temperature,
149
351000
3000
过了几天之后，依据温度状况，
06:09
the egg will hatch
150
354000
2000
蛋就会孵化出来，
06:11
and the larva of this parasite
151
356000
2000
寄生者的幼虫
06:13
will eat the aphid from the inside.
152
358000
3000
会从内部将蚜虫吃掉。
06:16
This is all natural. This is all natural.
153
361000
3000
这一切都是自然的现象。
06:19
This is not fiction, nothing at all.
154
364000
2000
这可不是小说里幻想的内容。
06:21
Again, in your backyard,
155
366000
2000
还有，就在你的后院里，
06:23
in your backyard.
156
368000
3000
在你的后院里也会发生。
06:26
But this is the end result.
157
371000
2000
这就是最后的结果。
06:28
This is the end result:
158
373000
2000
这就是最后的结果：
06:30
Mummies --
159
375000
2000
木乃伊 --
06:32
M-U-M-M-Y.
160
377000
2000
木 - 乃 - 伊。
06:34
This is the visual result of a dead aphid
161
379000
3000
这是蚜虫死亡后的外观。
06:37
encompassing inside,
162
382000
2000
我们看看里面。
06:39
in fact, a developing parasitoid
163
384000
3000
事实上，寄生者成长的过程中
06:42
that after a few minutes you see halfway out.
164
387000
3000
几分钟后你就会看见它几乎跑出来了。
06:45
The birth is almost complete.
165
390000
2000
它已经几乎变成成虫了。
06:47
You can see, by the way, in different movies, etc.,
166
392000
3000
你可以在完整的纪录片中看见这个。
06:50
it takes just a few minutes.
167
395000
2000
这只不过是几分钟的事情。
06:52
And if this is a female, she'll immediately mate with a male
168
397000
3000
如果这只是雌锋，它会立即和雄蜂交配，
06:55
and off she goes because time is very short.
169
400000
3000
之后就会立刻离开，因为它们生命太短。
06:58
This female can live only three to four days,
170
403000
3000
雌蜂只能存活三到四天的时间，
07:01
and she needs to give rise
171
406000
2000
它必须生出
07:03
to around 400 eggs.
172
408000
2000
大约4百个蛋。
07:05
That means she has 400 bad aphids
173
410000
3000
意思是说，它必须找到400只
07:08
to put her eggs
174
413000
2000
有害的蚜虫
07:10
into their body fluids.
175
415000
2000
将蛋放进它们的体液中。
07:12
And this is of course not the end of it.
176
417000
2000
这还没完。
07:14
There is a whole wealth of other natural enemies
177
419000
2000
还有许多其他的天敌，
07:16
and this is just the last example.
178
421000
2000
这只是最后的一个例子。
07:18
Again, we'll start first with the pest:
179
423000
2000
我们再回头来看看这个害虫：
07:20
the thrips.
180
425000
2000
牧草虫。
07:22
By the way, all these weird names --
181
427000
2000
对了，关于这些奇怪的名字 --
07:24
I didn't bother you with the Latin names of these creatures,
182
429000
3000
我们这边不谈正式的学名，
07:27
okay, just the popular names.
183
432000
2000
嗯，这些只是俗称而已。
07:29
But this is a nice, slender,
184
434000
2000
这是一种很细小，很苗条，
07:31
very bad pest.
185
436000
2000
很可怕的害虫。
07:33
If you can see this, sweet peppers.
186
438000
2000
看看这个甜椒。
07:35
This is not just an exotic, ornamental sweet pepper.
187
440000
3000
这可不是外国品种，也不是装饰用的甜椒，
07:38
This is a sweet pepper which is not consumable
188
443000
3000
这是一个已经不能吃的甜椒，
07:41
because it is suffering from a viral disease
189
446000
3000
因为它被那些牧草虫所带的
07:44
transmitted by those thrip adults.
190
449000
3000
滤过性病毒所感染了。
07:47
And here comes the natural enemy,
191
452000
2000
接下来，天敌登场了，
07:49
minute pirate bug,
192
454000
2000
微小的掠食虫，
07:51
"minute" because it is rather small.
193
456000
3000
说微小是因为它真的很小。
07:54
Here you can see the adult, black, and two young ones.
194
459000
3000
你可以看见那只黑色的成虫，还有两只幼虫。
07:57
And again, in action.
195
462000
2000
接下来又到了行动时间。
07:59
This adult pierces the thrips,
196
464000
3000
成虫刺穿了牧草虫，
08:02
sucking it within just several minutes,
197
467000
2000
只花了几分钟的时间去吸食它，
08:04
just going to the other prey,
198
469000
2000
然后就换另一个目标下手，
08:06
continuing all over the place.
199
471000
2000
随处持续着吸食。
08:08
And if we spread those minute pirate bugs, the good ones,
200
473000
4000
如果我们散布这种微小的掠食虫，那种益虫，
08:12
for example, in a sweet pepper plot,
201
477000
2000
例如在种植甜椒的菜园里，
08:14
they go to the flowers.
202
479000
3000
它们会躲藏在花朵中。
08:17
And look, this flower is flooded
203
482000
2000
看这里，当那些掠食性的益虫
08:19
with predatory bugs, with the good ones
204
484000
3000
将那些害虫牧草虫都清理干净后，
08:22
after wiping out the bad ones, the thrips.
205
487000
3000
花朵里挤满了这些益虫。
08:25
So this is a very positive situation, by the way.
206
490000
3000
所以这是相当正面的情况。
08:28
No harm to the developing fruit. No harm to the fruit set.
207
493000
3000
对成长中的果实不会有害处，对成熟的果实也没有害处。
08:31
Everything is just fine under these circumstances.
208
496000
3000
在这种情况下，一切都很美好。
08:34
But again, the question is,
209
499000
2000
不过问题是，
08:36
here you saw them on a one-to-one basis --
210
501000
2000
你可以发现这是一种一物克一物的现象--
08:38
the pest, the natural enemy.
211
503000
3000
害虫和它的天敌。
08:41
What we do is actually this.
212
506000
3000
而我们正在做这件事。
08:44
In Northeast Israel,
213
509000
2000
在以色列的东北方，
08:46
in Kibbutz Sde Eliyahu,
214
511000
2000
在Sde Eliyahu的集体农场里，
08:48
there is a facility
215
513000
2000
有一个机构
08:50
that mass-produces those natural enemies.
216
515000
2000
正在量产那些天敌。
08:52
In other words, what we do there,
217
517000
2000
换句话说，我们在那儿所做的
08:54
we amplify,
218
519000
2000
就是去放大，
08:56
we amplify the natural control,
219
521000
3000
我们去放大自然抑制的效果，
08:59
or the biological control phenomenon.
220
524000
2000
或该说是生物抑制的机制。
09:01
And in 30,000 square meters
221
526000
3000
在三万五千平方尺的
09:04
of state-of-the-art greenhouses,
222
529000
2000
新型温室之中，
09:06
there, we are mass-producing those predatory mites,
223
531000
3000
我们正在量产那些掠食性的螨，
09:09
those minute pirate bugs,
224
534000
2000
那些微小的掠食性的虫，
09:11
those parasitic wasps, etc., etc.
225
536000
2000
那些寄生的胡蜂 ... 等等。
09:13
Many different parts.
226
538000
2000
分成许多不同的区域。
09:15
By the way, they have a very nice landscape --
227
540000
2000
对了，那儿有很棒的风景。
09:17
you see the Jordanian Mountains on the one hand
228
542000
3000
一边有约旦山脉，
09:20
and the Jordan Valley on the other hand,
229
545000
2000
另一边有约旦溪谷，
09:22
and a good, mild winter
230
547000
2000
还有很棒，很温和的冬天，
09:24
and a nice, hot summer,
231
549000
2000
以及很赞，很热的夏天，
09:26
which is an excellent condition
232
551000
2000
对于量产这些生物来说，
09:28
to mass-produce those creatures.
233
553000
2000
这些都是极佳的条件。
09:30
And by the way, mass-production --
234
555000
2000
对了，这边说的量产，
09:32
it is not genetic manipulation.
235
557000
2000
并不是基因改造工程。
09:34
There are no GMOs --
236
559000
2000
没有转基因生物
09:36
Genetically Modified Organisms -- whatsoever.
237
561000
2000
genetically modified organisms ( 生物基因改造)这种事。
09:38
We take them from nature,
238
563000
2000
我们从自然界把益虫找来，
09:40
and the only thing that we do,
239
565000
2000
我们只做一件事，
09:42
we give them the optimal conditions,
240
567000
2000
我们提供最佳的条件，
09:44
under the greenhouses or in the climate rooms,
241
569000
3000
在温室之中，或是在恒温室里，
09:47
in order to proliferate,
242
572000
2000
使得这些益虫能够
09:49
multiply and reproduce.
243
574000
2000
快速地大量繁殖。
09:51
And that's what we get, in fact.
244
576000
2000
事实上，这也正是我们所得到的结果。
09:53
You see under a microscope.
245
578000
2000
从显微镜下你可以看见，
09:55
You see in the upper left corner, you see a single predatory mite.
246
580000
3000
在左上角有单只的掠食性螨。
09:58
And this is the whole bunch of predatory mites.
247
583000
3000
我们这是在量产那种掠食性螨。
10:01
You see this ampoule. You see this one.
248
586000
3000
看看这个小瓶子。
10:04
I have one gram of those predatory mites.
249
589000
3000
这儿有一克的掠食性螨。
10:07
One gram's 80,000 individuals,
250
592000
3000
一克里有八万只，
10:10
80,000 individuals
251
595000
3000
八万只螨
10:13
are good enough
252
598000
2000
已经足以
10:15
to control one acre, 4,000 square meters,
253
600000
3000
在一英亩，也就是四千平方尺
10:18
of a strawberry plot
254
603000
2000
的草莓田中，
10:20
against spider mites for the whole season
255
605000
3000
在一整年的采收季节里，
10:23
of almost one year.
256
608000
3000
去解决那些蜘蛛螨。
10:26
And we can produce from this, believe you me,
257
611000
3000
而藉由这个，
10:29
several dozens of kilograms
258
614000
2000
我们每年可以生产出
10:31
on an annual basis.
259
616000
3000
几十公斤的数量。
10:34
So this is what I call
260
619000
2000
这就是我说的
10:36
amplification of the phenomenon.
261
621000
2000
去放大这种自然机制。
10:38
And no, we do not disrupt the balance.
262
623000
3000
我们并不是在破坏生态平衡。
10:41
On the contrary,
263
626000
2000
相反的，
10:43
because we bring it to every cultural plot
264
628000
3000
我们将这些益虫导入到那些
10:46
where the balance was already disrupted
265
631000
2000
已经被化学药剂
10:48
by the chemicals.
266
633000
2000
破坏生态平衡的农田，
10:50
Here we come with those natural enemies
267
635000
2000
我们使用了这些天敌
10:52
in order to reverse a little bit of the wheel
268
637000
3000
以期能够将情况反转过来，
10:55
and to bring more natural balance
269
640000
2000
藉由降低化学药剂的使用
10:57
to the agricultural plot by reducing those chemicals.
270
642000
3000
让农田能够达到更高的自然平衡。
11:00
That's the whole idea.
271
645000
2000
这就是我们的概念。
11:02
And what is the impact?
272
647000
2000
然而，成效如何呢？
11:04
In this table, you can actually see what is an impact
273
649000
3000
藉由这个表，你可以确切的看见，
11:07
of a successful biological control
274
652000
2000
藉由使用益虫成功进行生物抑制
11:09
by good bugs.
275
654000
2000
所获得的成效。
11:11
For example, in Israel,
276
656000
2000
例如，在以色列，
11:13
where we employ
277
658000
2000
我们在那儿
11:15
more than 1,000 hectares --
278
660000
3000
进行生物抑制害虫，
11:18
10,000 dunams in Israeli terms --
279
663000
2000
来保护甜椒园，
11:20
of biological pest controlling sweet pepper
280
665000
3000
已经超过了一千公顷 --
11:23
under protection,
281
668000
2000
用以色列的单位是一万杜纳亩，
11:25
75 percent of the pesticides
282
670000
2000
已经确实让农药的使用量
11:27
were actually reduced.
283
672000
2000
减少了75%。
11:29
And Israeli strawberries, even more --
284
674000
2000
而以色列的草莓园所使用的农药 --
11:31
80 percent of the pesticides,
285
676000
2000
则甚至减少了80%，
11:33
especially those aimed against pest mites in strawberries.
286
678000
4000
尤其是那些针对草莓上有害螨的农药。
11:37
So the impact is very strong.
287
682000
3000
所以效果是相当可观的。
11:40
And there goes the question,
288
685000
3000
接下来的一些问题，
11:43
especially if you ask growers, agriculturists:
289
688000
3000
尤其是当你问那些耕种者，农民们：
11:46
Why biological control?
290
691000
2000
为什么会选择生物抑制法?
11:48
Why good bugs?
291
693000
2000
为什么选择益虫?
11:50
By the way, the number of answers you get
292
695000
2000
不过，不管你问了几个人，
11:52
equals the number of people you ask.
293
697000
3000
每个人都会给你不一样的答案。
11:56
But if we go, for example, to this place,
294
701000
2000
比方说这个地方，
11:58
Southeast Israel,
295
703000
2000
以色列的东南方，
12:00
the Arava area above the Great Rift Valley,
296
705000
3000
大裂谷上面一点的阿拉瓦区域，
12:03
where the really top-notch --
297
708000
2000
那儿有着 --
12:05
the pearl of the Israeli agriculture
298
710000
2000
以色列最顶尖的
12:07
is located,
299
712000
2000
农业之宝，
12:09
especially under greenhouse conditions, or under screenhouse conditions --
300
714000
3000
尤其是在温室条件之下，在透明的房间中--
12:12
if you drive all the way to Eilat, you see this
301
717000
3000
如果你开车到Eilat埃拉特的话，
12:15
just in the middle of the desert.
302
720000
2000
你会发现它位于沙漠的中央。
12:17
And if you zoom in,
303
722000
2000
如果你仔细去看，
12:19
you can definitely watch this,
304
724000
2000
你一定可以看见，
12:21
grandparents with their grandchildren,
305
726000
2000
爷爷奶奶带着孙子们
12:23
distributing the natural enemies, the good bugs,
306
728000
3000
正在散布这些天敌，那些益虫，
12:26
instead of wearing special clothes
307
731000
2000
而不是穿戴着特殊衣物和防毒面具
12:28
and gas masks and applying chemicals.
308
733000
3000
去喷洒着化学药剂。
12:31
So safety, with respect to the application,
309
736000
3000
这种技术的使用是相当安全的，
12:34
this is the number one answer that we get from growers,
310
739000
3000
这是我们询问耕种者们为什么要用生物抑制法
12:37
why biological control.
311
742000
3000
所获得答案中的第一名。
12:40
Number two, many growers
312
745000
2000
而第二名的答案，
12:42
are in fact petrified
313
747000
2000
许多耕种者会担心
12:44
from the idea of resistance,
314
749000
3000
抗药性的问题，
12:47
that the pests will become resistant
315
752000
3000
担心这些害虫
12:50
to the chemicals,
316
755000
2000
会逐渐对农药产生抵抗力，
12:52
just in our case that bacteria
317
757000
2000
就像是白喉的病菌
12:54
becomes resistant to antibiotics.
318
759000
2000
对抗生素产生了抗体。
12:56
It's the same, and it can happen very quickly.
319
761000
3000
同样的，这可能很快就会发生了。
13:00
Fortunately, in either biological control
320
765000
2000
所幸，不论是生物抑制法，
13:02
or even natural control,
321
767000
2000
或是自然抑制法，
13:04
resistance is extremely rare.
322
769000
3000
都很难会遇到抵抗的力量。
13:07
It hardly happens.
323
772000
2000
这几乎不可能发生。
13:09
Because this is evolution,
324
774000
2000
因为这是一种物种演化；
13:11
this is the natural ratio,
325
776000
2000
这是一种自然的机率，
13:13
unlike resistance,
326
778000
2000
不像是生物本身
13:15
which happens in the case of chemicals.
327
780000
2000
会对药剂产生抵抗力。
13:17
And thirdly, public demand.
328
782000
3000
第三名的答案是，公众的需求。
13:20
Public demand -- the more the public
329
785000
3000
大众逐渐倾向于去支持
13:23
demands the reduction of chemicals,
330
788000
2000
降低化学药剂的使用量，
13:25
the more growers become aware of the fact
331
790000
3000
越来越多的耕种者发现到
13:28
they should, wherever they can and wherever possible,
332
793000
3000
他们应该竭尽所能，
13:31
replace the chemical control
333
796000
2000
改以生物抑制法
13:33
with biological control.
334
798000
2000
来取代化学药剂抑制法。
13:35
Even here, there is another grower,
335
800000
2000
甚至像是这个，另一名耕种者，
13:37
you see, very interested in the bugs,
336
802000
2000
她对这些小虫很有兴趣，
13:39
the bad ones and the good ones,
337
804000
2000
不论是害虫或是益虫，
13:41
wearing this magnifier already on her head,
338
806000
2000
手上拿着一个放大镜，
13:43
just walking safely
339
808000
2000
在农作物里面
13:45
in her crop.
340
810000
2000
安全地穿梭着。
13:47
Finally, I want to get actually to my vision,
341
812000
3000
最后，我想谈谈我的看法，
13:50
or in fact, to my dream.
342
815000
2000
或该说，是我的梦想。
13:52
Because, you see, this is the reality.
343
817000
2000
因为你知道吗，这就是现实状况。
13:54
Have a look at the gap.
344
819000
2000
看看这个落差。
13:56
If we take the overall turnover
345
821000
2000
如果我们计算
13:58
of the biocontrol industry worldwide,
346
823000
2000
全世界生物抑制法的花费，
14:00
it's 250 million dollars.
347
825000
3000
大约是二亿五千万美金。
14:03
And look at the overall pesticide industry
348
828000
3000
看看全世界在农作物上
14:06
in all the crops throughout the world.
349
831000
3000
使用的农药花费。
14:09
I think it's times 100 or something like that.
350
834000
3000
我想大概会是一百倍左右吧。
14:12
Twenty-five billion.
351
837000
2000
大约二百五十亿美金。
14:14
So there is a huge gap to bridge.
352
839000
3000
所以这有着很大的落差需要去填补。
14:17
So actually, how can we do it?
353
842000
2000
所以事实上，我们该怎么做？
14:19
How can we bridge, or let's say, narrow, this gap
354
844000
3000
我们要怎么去填补，或者说让这个落差
14:22
in the course of the years?
355
847000
2000
在每一年的生产中逐渐减小？
14:24
First of all, we need to find more robust,
356
849000
3000
首先，我们需要更多健康的，
14:27
good and reliable biological solutions,
357
852000
3000
有益的，可以信赖的生物方案，
14:30
more good bugs
358
855000
2000
更多的益虫，
14:32
that we can either mass-produce
359
857000
3000
不论是大量繁殖，
14:35
or actually conserve in the field.
360
860000
3000
或是在田野中保持它的数量。
14:38
Secondly, to create even more
361
863000
2000
第二，促使大众做出
14:40
intensive and strict public demand
362
865000
2000
更强烈和更严格的要求
14:42
to reduction of chemicals
363
867000
2000
来减少种植新鲜农产品时
14:44
in the agricultural fresh produce.
364
869000
3000
使用的化学药剂。
14:47
And thirdly, also to increase awareness by the growers
365
872000
3000
第三，加强耕种者
14:50
to the potential of this industry.
366
875000
3000
对于这种产业潜力的了解。
14:53
And this gap really narrows.
367
878000
2000
如此，这个落差就会变小。
14:55
Step by step, it does narrow.
368
880000
3000
逐渐地，它就会缩小。
14:59
So I think my last slide is:
369
884000
2000
所以我最后一张投影片是：
15:01
All we are saying, we can actually sing it:
370
886000
3000
我们所说的这些是可以做到的，
15:04
Give nature a chance.
371
889000
2000
请给大自然一个机会。
15:06
So I'm saying it on behalf of all the biocontrol
372
891000
2000
我谨代表自然抑制法的
15:08
petitioners and implementers,
373
893000
2000
倡导者， 执行者
15:10
in Israel and abroad,
374
895000
2000
无论是以色列还是其他国家，在这里呼吁：
15:12
really give nature a chance.
375
897000
2000
给大自然一个机会吧。
15:14
Thank you.
376
899000
2000
谢谢
15:16
(Applause)
