篇中篇，11.寄生植物dodder中的新文章：植物利用害虫天敌保护自己 求确认

匆匆淼

某种植物，利用黄蜂(wasp/parasitic wasp寄生蜂)----毛毛虫(caterpillar)的天敌，攻击毛毛虫。
　　【版本一】一篇是讲毛毛虫，植物，还有捕捉一种毛毛虫的动物，这三者之间的关系，这篇是最长的，我没太看懂....不好意思啊各位... 主要是讲什么/怎么样导致植物分泌一种物质使捕食者来消灭毛毛虫
　　 ；第一段猜测这三者的关系
　　 第二段就是科学家通过试验来验证这个猜测
　　有益补充：WASP会把它的幼虫LAVAE寄生到一种虫身上. 这种虫吃一种植物.这种植物在这种虫吃它时会分泌一种CHEMICAL, 这种CHEMICAL 会吸引WASP. 所以这种植物是通过另外一种生物来抵抗它的天敌.
　　【版本二】植物利用黄蜂攻击毛毛虫
　　 [旧JJ内容]讲一种树在受到caterpillar的攻击的时候可以释放出一种气味以吸引wasps来攻击这种caterpillar, 不仅如此，科学家还发现这种树还可以判断caterpillar是否在攻击自己而释放出不同的气味.
　　第一题问树枝被刮断时黄蜂会有什么反应，
　　有一道主题题（一共4题），另外的记不起来，sorry
　　再烦请机经作者确认是不是这个JJ？（2004年11月JJ）（感谢一位MM）
　　Parasitic and predatory arthropods often prevent plants from being severely damaged by killing herbivores as they feed on the plants. Recent studies show that a variety of plants, when injured by herbivores, emit chemical signals that guide natural enemies to the herbivores. It is unlikely that herbivore-damaged plants initiate the production of chemicals solely to attract parasitoids and predators. The signaling role probably evolved secondarily from plant responses that produce toxins and deterrents against herbivores and antibiotics against pathogens. To effectively function as signals for natural enemies, the emitted volatiles should be clearly distinguishable from background odors, specific for prey or host species that feed on the plant, and emitted at times when the natural enemies forage. Our studies on the phenomena of herbivore-induced emissions of volatiles in corn and cotton plants and studies conducted by others indicate that (i) the clarity of the volatile signals is high, as they are unique for herbivore damage, produced in relatively large amounts, and easily distinguishable from background odors; (ii) specificity is limited when different herbivores feed on the same plant species but high as far as odors emitted by different plant species and genotypes are concerned; (iii) the signals are timed so that they are mainly released during the daytime, when natural enemies tend to forage, and they wane slowly after herbivory stops.

有益补充：有的寄生黄蜂会把毛虫的神经节蛰伤，使之瘫痪，让她的小宝宝活生生地吃毛虫肉。而我们故事的主角，确切地说，是刻绒茧蜂属（学名Glyptapanteles）的几种黄蜂，更胜一筹，她会在毛毛虫体内下八十多个卵，黄蜂幼虫靠吃它的肉长大，最后幼虫钻出毛虫的身体，在附近结茧。此时毛虫还没有死，它守在黄蜂茧的旁边，如果有活物靠近，不管是谁，它都要疯狂地摇头晃尾，把它们吓走，保卫黄蜂主人的安全。它被黄蜂操纵了，成了一个黄蜂的僵尸保镖，一个半死不活的东西。

寂静里好像出现过的。。。顶上去。。。那个把80多个从下到毛虫体内 然后活生生地吃它太残忍了 ！！！！！！！！！！！！！
