研究了桃蚜对10种寄主植物的选择性以及青花菜、小白菜、油麦菜对桃蚜生长发育和繁殖的影响,并以作用因子组建3种寄主上桃蚜试验种群生命表。结果表明,芥菜、结球甘蓝、小白菜和青花菜为桃蚜的嗜好寄主;桃蚜在油麦菜上的发育历期较长,而产仔量较少;小白菜、青花菜上桃蚜种群趋势指数较大,分别为27.82和26.63,较适合桃蚜种群增长,油麦菜上桃蚜种群趋势指数较小,为16.82,对桃蚜种群增长有一定的抑制作用。

The election of Myzus persicae on the host plants and the effects of Broccoli,B.campestris var.Chinensis and Laetuca Satiuali on the development and reproduction of Myzus persicae were studied.The experimental population life table was set up by the factor affected.The results showed B.juncea.Brassica oleracea var.capitata L. ,Broccoli and B.campestris var.Chinensis were the good choose host plant of Myzus persicae.on the Laetuca satiuali ,Myzus persicae had longest development time and lowest natality,the index of population trend of M.persicae on B.campestris var.Chinensis and Broccoli were ...
