Temperature has profound effects on biological efficiency of parasitoid wasps. In the present study, effects of seven constant temperatures (12, 15, 20, 25, 30, 32 and 35 ± 0.5 ^°C) on the pre-adult development of Trichogramma brassicae (Hymenoptera: Trichogrammatidae) were investigated on Sitotroga cerealella (Lepidoptera: Gelechiidae). Temperature effects on the emergence rate and sex ratio were also determined. The development rate of T. brassicae was described using two linear and twenty non-linear functions and critical bioclimatic temperatures (i.e., T_min, T_opt, T_max and k) were estimated. Efficiency of models was assessed by different criteria (i.e., R², R²_adj, SSE, AIC, AIC_c, BIC and z_i). Rate of development increased from 12 to 30 ^°C but decreased at two higher temperatures (i.e., 32 and 35 ^°C). At all thermal regimes a higher number of female individuals was emerged than males (1.81, 2.23, 2.03, 1.44, 1.78 and 1.78 ♀: ♂, respectively). At 12 ^°C, the lowest rate of parasitoid emergence (9%) was observed. The lower threshold predicted by the two linear models were 8.13 (Ordinary regression method) and 8.36 ^°C (Ikemoto method). These models predicted the thermal constant for pre-adult development as 181 and 177 DD, respectively. The estimates of optimum temperature ranged from 30 to 32 ^°C with an upper threshold between 36 and 41 ^°C, depending on which model was used. Based on both biological and statistical goodness-of-fit criteria, the non-linear model of Lactin-1 had the best described the experimental data. The information herein highlighted the higher performance of T. brassicae at tropical conditions and can be helpful to predict possible effects of temperature on developmental rate, select the best period of time for inundative release and improve mass rearing protocols of this parasitoid wasp.

温度对寄生蜂的生物效率具有深远的影响。在本研究中，7恒定的温度（12，15，20，25，30，32和35±0.5的效果 ^°上的预成人发展C）赤眼蜂甘蓝（膜翅目：赤眼蜂科）上进行了调查Sitotroga cerealella（鳞翅目：Gelechiidae）。还确定了温度对出苗率和性别比的影响。的发展率T.甘蓝使用两个线性和20的非线性函数和临界温度生物气候（即，进行了说明Ť_分钟，Ť_选择，Ť_最大值和ķ）进行估算。通过不同的标准（即R ²，R ² _adj，SSE，AIC，AIC _c，BIC和z _i）评估模型的效率。显影速率从12 ^° C增加到30  ^° C，但在两个较高的温度下（即32和35 ^° C）下降 。在所有热态下，出现的女性人数都多于男性（分别为1.81、2.23、2.03、1.44、1.78和1.78♀：♂）。在12  ^°C，观察到最低的寄生虫发生率（9％）。这两个线性模型预测的下限阈值为8.13（普通回归方法）和8.36  ^° C（Ikemoto方法）。这些模型预测成年前发育的热常数分别为181和177 DD。最佳温度的估计范围为30至32  ^° C，上限介于36至41  ^° C之间，具体取决于所使用的模型。基于生物学和统计学拟合优度标准，Lactin-1的非线性模型最能描述实验数据。本文中的信息强调了芸苔科的较高性能 在热带条件下，可以帮助预测温度对发育速度的可能影响，选择最佳时间过分释放并改善这种寄生蜂的质量饲养方案。
