摘要
【目的】明确不同温度对草栖钝绥螨Amblyseius herbicolus(Chant)种群增长的影响。【方法】利用年龄-龄期两性生命表研究草栖钝绥螨以贝氏小奥林螨Oulenzia bakeri(Hughes)为食,在5种温度(19、22、25、28和31℃)下的发育历期、存活率、繁殖力和种群参数。【结果】草栖钝绥螨的成螨前期和产卵前期在25℃时最短,分别为5.4 d和2.2 d,产卵期、繁殖力、内禀增长率r、周限增长率λ、净增殖率R_(0)等种群参数也是在25℃时最高,分别为12.6 d、26.0粒/雌、0.2 d^(-1)、1.2 d^(-1)、12.5;温度高于25℃后草栖钝绥螨各参数显著下降。【结论】不同温度下草栖钝绥螨均能完成生活史,25℃更适合草栖钝绥螨种群的繁育。
[Objectives]To clarify the effects of different temperatures on the population growth of Amblyseius herbicolus(Chant)feeding on Oulenzia bakeri(Hughes).[Methods]An age-stage,two-sex life table was used to determine the developmental period,survival rate,fecundity and population parameters,under five temperatures(19,22,25,28,31℃),85%±5%RH and a 16︰8 h(L︰D)photoperiod.[Results]The preadult and preoviposition periods first shortened,then lengthened with increasing temperature within the range of 19 to 28℃.These periods were shortest at 25℃(5.4 and 2.2 d,respectively).The oviposition period,fecundity,intrinsic rate of increase(r),finite rate of increase(λ)and net reproductive value(R_(0)),first increased,then decreased,with temperature,and were highest at 25℃(12.6 d,26.0 eggs/female,0.2 d^(-1),1.2 d^(-1),12.5,respectively).All measured population parameters decreased significantly at temperatures>25℃.[Conclusion]Although A.herbicolus can complete its growth and reproduction at temperatures in the range of 19 to 31℃,25℃is the optimal temperature within this range for breeding this species in captivity.
