华南大黑鳃金龟Holottichia sauteri Moser是福建沿海农区为害果林和旱地作物的常见主要害虫。国内以往对此虫的研究报道少见,现将其生物学特性的初步研究记述于下。 一、年生活史 据1980—1983年在晋江县古福村以甘薯为幼虫的饲料饲养观察结果,看出此虫一年发生一代,以成虫在土中越冬,于第二年春才出土活动。完成一代的生活历期需142—202天,卵期为15—31天,幼虫期为106—156天,蛹期为
Holottichia sauteri Moser, South China, is a common pest of pests and dryland crops in coastal Fujian. In the past, there were few reports about the research on this pest in China, and the preliminary study on its biological characteristics is now described below. First, the annual life history 1980-1983 Gufu Village, Jinjiang County to sweet potato larvae feed observations, we see that the pests occur a generation a year to adult worms in the soil overwintering in the spring of the second unearthed activity. It takes 142-202 days to complete the life cycle of a generation, the oviposition period is 15-31 days, the larval stage is 106-156 days, and the pupal stage is
