微生物对昆虫行为的影响研究进展

Research progress of the influence of microorganisms on insect behavior

在漫长的进化过程中,微生物与昆虫形成了多种形式的互作关系。微生物的广泛分布为与昆虫接触并影响昆虫的行为提供了背景条件。为了深入探究微生物影响昆虫行为的现象和机制,本文综述了微生物影响昆虫行为方面的研究进展。微生物通过产生可被昆虫识别的化学信号物质、参与昆虫或寄主植物信息化合物的合成等方式可影响昆虫对其寄主的定位和选择。在对昆虫种内和种间关系的研究中也发现微生物起着非常重要的作用。通过改变昆虫性信息素等方式,微生物还能影响到昆虫的繁殖行为;除此之外,微生物合成或参与合成的信息化合物还可以影响昆虫的社会性和聚集等行为。根据当前对微生物影响昆虫行为方面的研究现状,我们建议可进一步研究:(1)微生物影响昆虫行为的过程中,影响昆虫行为的信息化合物是如何产生的?(2)微生物在影响昆虫行为的过程中是否涉及更多的物种间互作?(3)对于一些在特定时期可影响昆虫行为的共生微生物来说,宿主昆虫是如何获得并维持这些微生物的?

In the long evolutionary process,a variety of forms of interaction between microorganisms and insects have been formed.The wide distribution of microorganisms provides background conditions for their contact with insects and influence on insect behavior.To further explore the phenomenon and mechanism of microorganisms influencing insect behaviors,the research progress of the influence of microorganisms on insect behaviors was reviewed in this article.Host location and selection of insects can be influenced by chemical signal substances produced by microorganisms,and the synthesis of semiochemicals in insects and host plants can also be influenced by microorganisms.Microorganisms have also been found to play important roles in intraspecific and interspecific relationships of insects.Microorganisms can even influence the reproductive behavior of insects by altering,for example,insect sex pheromones.Besides,social and aggregation behaviors of insects are also found to be influenced by semiochemicals synthesized by microorganisms.Considering the current research status of the influence of microorganisms on insect behaviors,the following aspects are suggested to be further investigated:(1)How are semiochemicals that influence insect behavior synthesized in the processes of influencing insect behavior by microorganisms?(2)Do microorganisms involve more interspecies interaction in influencing insect behavior?(3)How do host insects acquire and maintain symbiotic microoganisms that influence insect behavior at certain stages?
