捕食樟白轮蚧Aulacaspis rosarum的四种瓢虫生物学特性的研究

红点唇瓢虫、湖北红点唇瓢虫、细缘唇瓢虫、中原寡节瓢虫是樟白轮蚧的捕食性天敌,它们的形态特征、生活习性各异,但均以樟白轮蚧为主食。细缘唇瓢虫日平均取食量居四者之首,其次为湖北红点唇瓢虫,再次为红点唇瓢虫。

STUDY ON BIONOMICS OF FOURLADYBIRD BEETLES PREYING ON Aulacaspis roarum

Chilocorus kwwanae Silvestri, Chilocorus hupehanus Miyatake, Chilocorus circumda-tus (Gyllenhal) and Telsimia nigra centralis Pang et Mao are all the natural enemies of Aulacaspis rosarum Borchsenius, preying on Aulacaspis rosarum Borchsenius as stable food even though they are different in morphological and life characteristic. According to their avarage preying amount on Aulacaspis rosarum Borchenius, Chilocorus circumdatus (Gyllenhal) ranks first, Chilucorns hu-peharus Miyatake second and Chilocorus kuwanae Silvestri third.
