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.展开更多

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.
