丝瓜瘿蚊在赣中地区以老熟幼虫在虫瘿内越冬，1年发生6～7代。以第1代为害最重，以为害幼茎为主。虫瘿密度(x)与产量损失率(y)的关系符合y=-1.1042+1.3997x。丝瓜瘿蚊的防治指标为每代虫瘿4～5束/蔸。消灭越冬虫源、人工摘除虫瘿、在成虫始盛期至卵孵高峰期施药，防治效果较好。

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.
