摘要
本文报道了在瑞丽、畹町、昆明的仓储条件下用小麦、绿豆、花生饲养谷斑皮蠹,观察其生长繁殖,把仓储与气象的温湿度对照分析得出:当仓温连续5-6个月在25℃时有利该虫繁殖生存;仓温连续5个月在21.8-23℃时该虫可生存很长一段时间但有时可化蛹完成一世代,有时仅脱皮不化蛹完不成一世代.三种饲料中繁殖倍数为小麦>绿豆>花生.笔者认为:探讨该虫在一地区能否生存和为害,除仓储温湿度外尚需考虑天敌、虫种间竞争关系诸问题.
The culture of Trogoderma granarium everts with wheat, mung bean and peanut as feed under the storage conditions of grain in Ruili, Wanding and Kunming was repored. It was concluded that a storage temperature of 25℃ kept for 5-6 months is favorable to living and breeding of the beetle. When storage temperature was maintained at 21.8-23℃ for 5 months, the beetle can exist for very long time and can either pupate to complete a generation or merely exuviate but didn't pupate to complete a generation. Breeding rates with different feeds are in following order: wheat>mung bean>peanut.Besides storage temperature, it is necessary to consider other elements such as natural enemies and competition between beetle species, if the possibility of existence of the beetle in these regions and the extent of harmness of the beetle to stored grain are regarded.
