在20℃、25℃、30℃和32℃条件下，研究了寄生雄小蜂小蜂Encarsia inaron(Walker)的生活史和生活表参数。雌蜂从卵到成虫的发育时间从20℃的31.7d到30℃的15.0d不等，平均需要305.4℃以上的阈值温度才能完成发育。成虫在20、25、30和32℃时的存活率分别为80.8%、86.6%、72.5%和64.4%。雌虫平均寿命在20℃时为22.3天，32℃时为4.5天。平均总产卵量为12~74粒/雌。性别比(女性%)为54%~82%。在不同温度下，种群的内禀增长率(r(M))在0.113~0.203雌/天之间，最高记录在25℃。这些数据对人工饲养野大头翁以及了解其在管理雄刚毛虫时的表现有一定的意义。(C)2011爱思唯尔有限公司。保留所有权利。
The Life history and life table parameters of the parasitoid Encarsia inaron (Walker) parasitizing Neomaskellia andropogonis Corbett were studied at 20, 25, 30 and 32 degrees C. Egg-to-adult development time of females ranged from 31.7 days at 20 degrees C to 15.0 days at 30 degrees C. An average of 305.4 degree-days was required to complete development above the lower threshold temperature (10.8 degrees C). Pre-adult survivorship was 80.8, 86.6, 72.5 and 64.4% at 20, 25, 30 and 32 degrees C, respectively. Mean longevity of adult females E. inaron ranged from 22.3 days at 20 degrees C to 4.5 days at 32 degrees C. Mean total fecundity ranged from 12 to 74 eggs/female. The sex ratio (female %) ranged from 54 to 82%. The intrinsic rate of population increase (r(m)) at the different temperatures ranged from 0.113 to 0.203 females/female/day, with the highest value recorded at 25 degrees C. These data have implications for commercial rearing of E. inaron as well as for understanding its performance when used for the management of N. andropogonis. (C) 2011 Elsevier Ltd.
