摘要
菜青虫在少量取食苦参碱混剂处理的叶片后,生长发育明显受到抑制;1.8％苦参碱+0.04％齐螨素混剂处理可使5龄菜青虫的拒食率达87.8％;保叶效果的盆栽试验中,苦参碱混剂处理效果优于乐果处理.
The growth of Pieris rapae L. was inhibited remarkably after eating the leaves mixed with a little matrine. The anti-food rate of five-age Pieris rapae L. could reach 87. 8% if treated with 1.8% matrine and 0. 04% abamectin. The pot cultivating experiment of leaf protecting effect showed that the effects of matrine mixtures were better than that of flolimat latex.
