摘要
本文在 2 5℃条件下初步研究了胡瓜钝绥螨捕食茶橙瘿螨的实验种群生命表、各螨态取食量及猎物——卵转化率。 2 5℃时胡瓜钝绥螨的净增殖率 R0 =2 1.786 2 ,世代平均周期 T=16 .182 2 ,内禀增长率 rm=0 .190 4 ,周限增长率 λ=1.2 0 97,种群倍增所需时间 t=3.6 40 5。日平均产卵量 2 .19粒 /天 ,总产卵量 36 - 48粒 /雌 ,平均 38.97粒 /雌。胡瓜钝绥螨雌螨一生取食量 1978.4 9头 ,雄螨取食量 879.5 6头。猎物 :卵转化率为 79.78头茶橙瘿螨 :2 .
The life table of laboratory population of Amblyseius cucumeris preying on tea pink mites were constructed at the constant temperature of 25℃. The intrinsic rate of natural increase (rm), net reproductive rate (R 0), mean generation time (T) and the finite rate of increase (λ) were obtained as follows(25℃,85%RH): r m =0.1904, R 0=21.7862, T=16.1822, λ=1.2097. The population can develop at double in 3.6405 days only. The mean number of eggs was 38.97eggs/female, with daily oviposition rate of 2.19 eggs/female/day at 25℃.The female could prey on 1978.49 tea pink mites and the male could prey on 879.56 tea pink mites.
