我国桃小食心虫性信息素应用技术研究进展

Research Progress on the Application Technology of Sex Pheromones in Carposina sasakii in China

桃小食心虫(Carposina sasakii)是我国分布广泛的一种重要果树害虫,以蛀果为害,严重影响果实的产量和品质,给果业造成巨大的经济损失。本文就桃小食心虫的发生与危害、性信息素的鉴定与合成、监测诱捕与干扰交配应用技术方面进行了综述。桃小食心虫在我国大多数地区1 a发生1~2代,幼虫主要在树冠上部为害;其性信息素成分主要为顺-7-廿烯-11-酮和顺-7-十九烯-11-酮,人工合成产率从10%提高到60%;监测诱捕中建议使用150个·hm^(-2)的白色粘虫板配套船形诱捕器悬挂于树冠上部;干扰交配应用中建议使用迷向剂450~600个·hm^(-2)。并提出目前性信息素生产及应用中存在的问题,为全面了解桃小食心虫的研究进展和创新研究方向提供参考依据。

Carposina sasakii is an important fruit pest widely distributed in China,which infests the fruit,seriously affecting the yield and quality of the fruit and causing great economic losses to the fruit industry.In this paper,the occurrence and damage,identification and synthesis of sex pheromones,monitoring and trapping,and application techniques of mating disruption were reviewed.It occurred 1−2 generations in a year in most regions of China,and the larvae were mainly infested in the upper part of the tree crown.The primary constituents of the sex pheromone were(Z)−7−Eicosen−11−one and(Z)−7−Nonadecen−11−one,and the synthetic yield had been increased from 10%to 60%.It was advisable to utilize 150 per hm^(-2) white armyworm plates along with boat-shaped traps suspended above the tree canopy for monitoring purposes,and 450−600 per hm^(-2) sex pheromone for disrupting the mating were recommended for mating disruption.The existing problems in the production and application of sex pheromones were put forward to provide reference and basis for a comprehensive understanding of the research progress and innovative research directions of Carposina sasakii.
