[Research progress on biology and ecology of Harmonia axyridis Pallas (Coleoptera: Coccinellidae)].

Harmonia axyridis Pallas (Coleoptera: Coccinellidae) with its native in Asia is one of the most important predatory ladybird beetles, and used worldwide as a biological control agent. This paper summarized the recent decades research progress at home and abroad on its life history, reproductive strategies, and predatory and cannibalism behaviors, and analysed the prospects of its utilization. Based on the review of its artificial reproduction, insecticide interaction, and impact as an invasive species, some useful measures were suggested to prevent the beetle from its potential risk to ecological banlance.
