摘要
Abstract
In the middle of Jiangxi province, Lasioptera sp. overwinters in gall by mature larvae, there are 6～7 generations in a year, this insect mainly injures young stem of sponge gourd, the most serious injury is caused by the first generation. The relationship between gall density(x) and percentage of yield loss(y) coincides with the following equation: y=-1.1042+1.3997x. The economic threshold of Lasioptera sp.is 4～5 galls per plant per generation. Wiping out the overwintering insect source, clearing away the galls and applying insecticides in early peak period of adult and peak period of incubation have better control effects on this insect.关键词
