摘要
本文报道了栗瘿蜂发生规律和防治研究结果。该蜂在昆明1年发生1代,以幼虫越冬,1月中、下旬越冬幼虫恢复活动,是药剂防治的有利时机,以50％磷胺包扎防效好。该蜂幼虫期有两种体外寄生蜂,总寄生率达61.76％。
This paper presents the results of studies of bionomics and control of the chestnut gall wasps (Dryocosmus kuripkilus yasumatsu). The gall wasps have one generation in Kunming annually and overwinter as larvae in the galls. Those larvae resume their feeding in middle and late January, It is also the proper time to apply insecticides to control the gall wasps. Two species of Hymenopterous parasitoids have been recorded from the Dryocosmus galls. and their total parasitizing rate reached 61.76%.
