摘要
菜蚜茧蜂(Diaeretiella rapae)是蔬菜蚜虫的重要天敌。为了明确菜蚜茧蜂对我国常见4种蔬菜蚜虫的控制作用,通过室内试验,研究了菜蚜茧蜂对萝卜蚜、甘蓝蚜、豌豆蚜和蚕豆蚜的寄生作用。结果表明:菜蚜茧蜂对萝卜蚜和甘蓝蚜具有较好的控制作用,放蜂后21 d,其寄生率多在20%以上;对豌豆蚜的寄生作用较弱,放蜂后21 d,寄生率最高不超过10%;对蚕豆蚜寄生率最低,多在1%左右,只有极少数蚜虫被寄生。
Diaeretiella rapae, an important parasitoid of aphids in the world, was released with 6 ratio to control Lipaphis erysimi,Brevicoryne brassicae, Acyrthosiphon pisum and Aphis craccivora in Yuxi City Yunnan Province. The results showed that the parasitoid could control Lipaphis erysimi and Brevicoryne brassicae availably, and the parasitism was above 20% after releasing the parasitoid in21 days, but the parasitism was only 10% to control Acyrthosiphon pisum, and only 1% to control Aphis craccivora. The results providedevidence to control the aphids on vegetables by releasing Diaeretiella rapae (McIntosh).
