菜蝽Eurgdema domiulus(Scopoli)是油菜、白菜、芥菜、萝卜等十字花科油科及蔬菜作物的重要害虫之一。当十字花科植物衰老时或收割后,也可转害某些菊科及豆科植物。成虫和若虫均吸食植株的汁液。茎叶被害后,轻则呈现黄色斑点,花苔萎缩,结实少而不饱满;重则叶色枯黄,花苔枯萎,完全不实。对十字花科菜类的产量、质量及留种,影响甚大。有关菜蝽的生物学特性,国内虽有过一些报导,但均不够完整。近两年来,我们进行了较系统的饲养和调查,现将所得结果,概括整理如下。
Eurgdema domiulus (Scopoli) is one of the important pests of Cruciferous oil and vegetable crops such as rapeseed, cabbage, mustard and radish. Cruciferous plants and legumes can also be spoiled when cruciferous plants are aged or harvested. Adult and nymphs ingest plant juice. Stems and leaves were killed, ranging from light yellow spots, moss atrophy, fruiting less full; weight is yellow, heavy wither, completely false. Cruciferous vegetables on the yield, quality and remaining species, have a great impact. About the biological characteristics of the bug, although there have been some reports, but are not complete enough. In the past two years, we have conducted systematic rearing and surveys. The results obtained are summarized below.
