昆虫对植物挥发性信息化合物的影响与利用

The effects and utilization of insect on plant semiochemical volatiles

昆虫能影响、利用植物的挥发性信息化合物。昆虫通过取食时产生的口腔的分泌物改变植物挥发性信息化合物的释放,这种改变不同于由机械损伤诱导的改变,这两种情况下释放的挥发性信息化合物具有不同的生态学意义。昆虫对植物挥发性信息化合物的诱导释放具有系统性和群体性,并能利用寄主植物特有的挥发性信息化合物寻找适宜的行为场所,利用植物在不同诱因下挥发性信息化合物的改变避免昆虫种内、种间的生存竞争。研究昆虫对植物挥发性信息化合物的影响与利用,可以帮助人类寻找害虫的自然控制因子,探索环境友好型害虫防治途径。

Insects can affect and use plant semiochemical volatiles. The release of plant semiochemical volatiles can be changed by buccal secretion produced when insect feeding,which is different from the release induced by mechanical damage. The semiochemicat volatites released in the above two cases. have different ecological significance. The release of plant volatiles lured by insects has characters of system and colony. Insects can use these votatites to look for appropriate behavior places, avoid surviving competition inside species and outside species. Study on the effects and utilization of plant semiochemical volatiles by insects will help human search natural control factors against pests, which are friendly to environment.
