摘要
通过对荔枝蝽卵块的标记调查,在综防园中采集到荔枝蝽的两种卵寄生蜂——平腹小蜂和跳小蜂。在荔枝蝽产卵的中、后期,两种寄生蜂对荔枝蝽卵总寄生率达41.9%~47.1%,其中平腹小蜂寄生16.7%~18.4%,跳小蜂寄生23.5%~30.4%。在化防园中仅采集到平腹小蜂,且其寄生率相当低,只有0.9%~2.8%。
Two parasitoids were found to parasitize eggs of the litchi stink bug, Tessaratoma papillosa (Drury) in Guangzhou litchi orchards. The efficacy of control by these parasitoids was investigated in two orchards. In the IPM orchard the rate of control by these parasitoids was 41.9% ̄47.1% in June (Anastatus sp. 16.7% ̄18.4%, Ooencyrtus sp. 23.5% ̄30.4%), while in the chemical control orchard, only A. sp. parasitized eggs were found and the rate of control was very low (0.9% ̄2.8%).
