天牛科昆虫信息化合物研究现状

天牛科昆虫是危害严重的林业害虫,给林业生产造成重大损失。昆虫信息化合物的鉴定及应用,在害虫综合治理(IPM)中发挥着重要的作用。到目前为止,已从100多种天牛科物种中鉴定出信息化合物质,天牛亚科(Cerambycinae)、沟胫天牛亚科(Lamiinae)和椎天牛亚科(Spondylidinae)鉴定出雄性天牛的聚集信息素组分,花天牛亚科(Lepturinae)和锯天牛亚科(Prioninae)物种主要是鉴定出雌性天牛释放性的性信息素组分。这些信息素组分在不同亚科、不同属和种之间重叠率高,同一种组分可以在多种天牛物种中发挥作用,调节昆虫行为活动的信息化学物质在害虫治理中具有应用潜力和广阔的前景。对国内外已研究的天牛科信息素组分进行系统分析,可为今后鉴定新的天牛科信息素组分提供依据,加快我国天牛科信息素组分鉴定和应用进程。

Research on the Pheromone Compounds of Cerambycidae Insects

The identification and application of insect pheromone compounds play an important role in integrated pest management(IPM). Pheromone compounds are now identified from more than 100 species belonging to Cerambycidae. The pheromones identified to date from species in the subfamilies Cerambycinae, Spondylidinae, and Lamiinae are all male aggregation pheromones, whereas all known examples for species in the subfamilies Prioninae and Lepturinae are female sex pheromones. These pheromone components have a high overlapping ratio among the subfamilies, especially among the genera and the species. The same components can play a role in many species of Cerambycidae. The application potential and broad prospects of pheromone compounds regulating insect behavioral activities in pest management have made the research of pheromone compounds more important. To make a systematic analysis on the known pheromone components of Cerambycidae can provide evidence for the further identification of the pheromone components of other Cerambycidae species, and promote the identification and application of pheromone components in Cerambycidae.
