| 摘 要： | 矢尖蚧蚜小蜂在重庆一年发生11～12代,主要以幼虫越冬。田间虫口7月上旬至翌年8月发生最多,9月中旬和11月中旬为高峰期,每叶虫口分别为14.3和15.7头。但是,寄生率高峰出现在7月,达70％;其次为9、10月。寄主越冬期间寄生率仍达17～25.6％。为了保护天敌,建议柑桔园喷洒农药防治矢尖蚧,以在蚜小蜂发生量少的季节(5～6月)为宜。

| Abstract: | Aphvtis vanonensis Debach et Rosen, a new member of the A. lingnanenaia group, haa 11-12 generationa a year in Chongqing, Sichun Province. It overwinters mainly in the larval stage. Field populations increased during July to next March, the peak appearing from mid-Sept. to mid-Nov., when 14.3-15.7 wasps per leaf could be found in the orchard. The very peak for a 70% host paraaitization occured in July however. A parasltization rate of 17-25.6% was observed during the period of host overwintering. It is suggested that pesticide applications against Unaspis vanonensis should be conducted only when the parasite population is low. |
