摘要
以不同李品种为材料,采用物理和化学防治法对李小食心虫进行防治试验,结果表明：几种物理防治方法综合使用时,不同品种有虫果率在7.5%-17.2%之间,虫口减退率在74.6%-86.5%之间;化学防治时,有虫果率分别为26.3%、24.5%,虫口减退率分别为69.5%、71.6%。晚熟品种危害程度轻,中熟品种受害较重。
The control experiment was carried on Grapholitha funebrane with physics and chemical method by choosing different plum species as material. The result showed that the rate of fruit with insects of different species was between 7.5% and 17.2% and the insects reduced rate was between 74.6% and 86.5% by using several physics control method. The rate of fruit with insects was 26.3%, 24.5% and the insects reduced rate was 69.5%, 71.6%. The injury extent of late variety was lighter while the injury extent of medium variety was worse.
