摘要
八斑鞘腹蛛(Coleosoma octomaculatum)是农田害虫的主要天敌之一。它分布范围广、数量大,可捕食棉蚜(Aphis gossypii)、豆蚜(A.craccivora)、柳蚜(A.saliceti)、菜缢管蚜(Lipaphis erysimi)、麦长管蚜(Macrosi-
The development duration and survival ratio of Coleosoma octomaculatum under 6 differenttemperatures are determined.Its development rate coordinates with Logistic curve.The mini-mum temperature for development in egg and spiderling stages is calculated as 9.76℃ and9.26℃ respectively.The relationship between survival ratio and temperature coordinates withporabola curve,with the highest generation survival ratio of 78.2% at 29℃.Based on abovedata,a life table of C.octomaculatum experimental population is established,which showsthat the growth index of the population is the highest at 23℃.
