摘　　要：本文报道了荔枝瘿螨天敌──亚热冲绥螨的生物学、世代历期、捕食效能及其种群消长规律。在室温２８一３１℃，相对湿度７８一８０％的实验条件下，亚热冲绥螨的卵期１．８７±０．５６天；幼螨期１．２７±０．４４天；第一若螨期１．５３±０．４６天；第二若螨期１．５０±０．６３天；产卵前期１．９０±０．５５天；全代历期８．０７±１．３３天。The paper dealt with the bionomics ,generation durations, predatory efficiency andpopulation dynamics of Okiseius subtropicus Ehara which was the natural enemy of Eriophyes litchii Keifer,Under the experimental conditions of 28一31℃ and RH 78一80%,the meandurations of egg,larva,first nymph,second nymph,preoviposition and a generation lasted1.87±0.56,1.27±0.41,1.53±0.46,1.50±0. 63,1.90±0.55,and 8.07± 1.33 daysrespectively,The model of predatory efficiency for Okiseius sublropicus was Na=
