青海云杉(拟)齿小蠹聚集信息素研究进展

Research Progress on Aggregation Pheromone Systems of Major Ips /Pseudips Bark Beetles Attacking the Thickleaf Spruce:A Mini-Review

对危害青海云杉的光臀八齿小蠹、香格里拉齿小蠹及东方拟齿小蠹聚集信息素系统进行研究,并成功鉴定出3种(拟)齿小蠹的聚集信息素组分。光臀八齿小蠹聚集信息素由2-甲基-3-丁烯-2-醇,74%-(-)-小蠹二烯醇和(S)-顺式-马鞭草烯醇3种成分组成;香格里拉齿小蠹聚集信息素的有效组分为2-甲基-3-丁烯-2-醇,99%-(+)-小蠹二烯醇和(S)-顺式-马鞭草烯醇,东方拟齿小蠹聚集信息素由95%-(-)-小蠹烯醇和(S)-顺式-马鞭草烯醇2种成分组成。3种人工合成的小蠹虫聚集信息素已在害虫发生期及种群动态监测中进行野外试验,并取得预期效果。

The aggregation pheromone systems of three major spruce bark beetles,Ips nitidus,I.shangrila,and Pseudips orientalis in Qinghai,China,were recently identified in a joint international effort.2-methyl-3-buten-2-ol,74%(-)-ipsdienol and(S)-cis-verbenol are the aggregation pheromone components of I.nitidus;2-methyl-3-buten-2-ol,99%-(+)-ipsdienol and(S)-cis-verbenol are determined as the aggregation pheromone components of I.shangrila,whereas 95%-(-)-ipsenol and(S)-cis-verbenol are the primary aggregation pheromone components for P.orientalis.Traps baited with the corresponding synthetic aggregation pheromone lures have been used as an efficient monitoring tool in an integrated pest management program against these serious forest pest insects,and might also have a potential for future mass-trapping.In the current mini-review,we summarized the recent research and progress related to the aggregation pheromone identification work,especially for the Chinese speaking readers.
