天牛类昆虫交配行为研究进展

天牛是一类在我国危害严重且防治难度较大的林木蛀干害虫.虽然其种类众多,经济和生态价值大,但国内外较少有对天牛繁殖交配行为的总结报道.梳理国内外对天牛交配行为的研究,发现天牛交配行为可分为求偶、性冲动、交配前准备、交配四个阶段,每个阶段都不可缺少,且有其阶段特征性的行为.在交配后,一些雄性天牛会表现出配后保护行为.天牛交...

Review on mating behavior of longhorn beetle

Some of longhorn beetles are important forest pests in the world and difficult to control.Even they caused heavy economic and ecological damage,their mating behaviors,which have great impacts on reproduction and population development,were not given enough attention and research.By summarizing existing studies,the mating behavior of longhorn beetles could be divided into four stages:courtship stage,sexual impulse stage,pre-mating preparation stage and mating stage.Each stage was indispensable and had its characteristic behavior.After mating,the males of some species showed post-copulatory guarding behavior toward the females.The mating behavior of longhorn beetles was affected by many factors,including the volatile or non-volatile sex pheromones or aggregation pheromones secreted by females or males,host plants,adult age,body size and the color of male beetles,etc.Based on studies on mating behavior of longhorn beetles,some control methods could be developed to inhibit the reproduction of adults to some extent,and reduced the population density of the next generation.
