蜜露对天敌昆虫生长繁殖及搜寻行为的影响

已有研究表明:同翅目昆虫蜜露对一些天敌昆虫有着特殊的作用。一方面,蜜露可用来补充营养,从而促进天敌若虫死亡率下降、成虫寿命延长以及繁殖力提高;另一方面,蜜露作为天敌搜寻行为的信息物质。而人工蜜露在很多情况下对部分天敌也具有上述2方面的作用。文章就此内容的研究进展作一概述,以期促进蜜露在天敌昆虫人工饲养、害虫综合防治以及其他方面发挥作用。

Impacts of honeydew on the growth, fecundity and foraging behavior of natural enemies

Honeydew secreted by homopterans has special effects on some natural enemies. On one hand, some natural enemies often use honeydew as one of sources of nutrient, which can improve the survival rate of nymphs, prolong the lifespan and raise the fecundity rate of adults. On the other hand, honeydew is often utilized as information substances for foraging behavior of some natural enemies. At the same time, artificial honeydew also has these effects on some natural enemies. Current knowledge in this field is reviewed.
