摘要
Homalotglus flaminus (Dalman) is an important natural enemy of the Chilocorus kuwanae. Its biological character-istic, life history, the action style on hosts were studied at Hongqi Forest Farm, Daqing City, Heilongjiang Province from June 1998 to October 2000, in order to control H. flaminus and raise the control ability of Chilocorus kuwanae to Quadraspidiotus gigas pest. The observed results indicated that H. flaminus has two generation one year in study area, the pupating span is 12.7 d, life span of females and males is 17.6 d and 10.8 d respectively, egg span is 10 d, and the sex ratio of females to males is 1:3.
隐尾跳小蜂(Homalotglus flaminus)是红点唇瓢虫(Chilocorus kuwanae)的重要天敌。为了防治隐尾跳小蜂提高红点唇瓢虫对杨夸圆蚧的防治能力,从1998年6月到2000年10月在黑龙江省大庆市红旗林场研究了隐尾跳小蜂的生物学特性、生活史及对寄主的作用类型。观察结果显示,在研究区域隐尾跳小蜂一年两代,化蛹期为12.7天,雌蜂的存活期为17.6天,雄峰的存活期为10.8天,卵期为10天,雌雄性别比为1:3。
