Natural enemies and population fluctuation of the palm scale, Hemiberlesia cyanophylli Signoret

, : Natural enemies and population fluctuation of the palm scale, Hemiberlesia cyanophylli Signoret. Chinese Journal of Entomologyrecd 1983; 1(2): 69-76

Field studies were carried out at Long Tan, Taoyuan, Taiwan, from January 1978 to December 1979 on factors causing mortality of Abgrallaspis cyanophylli (Sign.) (Hemiberlesia cyanophylli). The most important factors found included the fungus Pseudomicrocera henningsii and the hymenopterous parasite Aphytis chrysomphali (Merc.); observations made on the biology and morphology of these 2 species are described. The other factors found included another fungus, climatic factors and a predator.
