摘要:

评述了小蠹科昆虫化学信息通讯的复杂性和种间多样性,小蠹虫利它素、利己素和信息素在寄主树木选择、入侵、定居和繁殖中的行为调控机制。并讨论了化学信息素合成与分泌对小蠹虫种群密度和生态位宽度,以及天敌昆虫种类和数量动态的影响。

关键词: 小蠹虫, 化学信息素, 调控机制

Abstract:

This paper reviewed the status of complex and interspecies diversity of Bark Beetles chemical communication, discussed the behavior regulation mechanism of kairomones, allomones and pheromones in the host selection, attack, colonization and reproduction of Bark Beetles. And it stated that the semiochemicals biogenesis and release of Bark Beetles effect on the population density, spatial niche and attacking time, and effect on the entomophagous insect species, population density and their control role to Bark Beetles.

Key words: Bark Beetle, Semiochemical, Regulation role
