拟微丝菌（膜翅目：Braconidae）是斜纹夜蛾幼虫（鳞翅目：夜蛾科）的单内寄生。在此，在发展和繁殖力恒温（18，21，24，27，30，33和36°C）的效应M.线虫在显影斜纹夜蛾在实验室进行了研究，以阐明其潜在的范围分布并更好地了解其作为生物防治剂的潜力。泥螺的发育持续时间从10.6（33°C）到27.9天（18°C）不等。拟南芥的发育阈值温度和有效累积温度分别为9.96°C和231.14度·天。成人的平均寿命M. similis的范围从5.1（33°C）到26.8天（18°C）。在27°C和30°C下观察到了最大的产卵量，分别是43.07和39.73个卵。在18°C时观察到该寄生虫的最小繁殖力为8.27个卵。在30°C时，sim麻的固有增加率（r _m）和有限增加率（λ）最高。净繁殖率（R ₀）在27℃和30℃时最高，分别为44.34和40.39。我们得出的结论是，温度在27–30°C的范围内最适用于拟南芥的繁殖和繁殖。。我们的研究提供了在不同温度条件下development虫的发育和繁殖的详细基础信息。

Effects of temperature on the development and fecundity of Microplitis similis (Hymenoptera: Braconidae), a parasitoid of Spodoptera litura (Lepidoptera: Noctuidae)

Microplitis similis (Hymenoptera: Braconidae) is a solitary endoparasitoid of Spodoptera litura larvae (Lepidoptera: Noctuidae). Here, the effects of constant temperature (18, 21, 24, 27, 30, 33 and 36 °C) on the development and fecundity of M. similis developing in S. litura were studied in the laboratory to clarify the range of its potential distribution and better understand its potential as a biological control agent. The developmental duration of M. similis varied from 10.6 (33 °C) to 27.9 days (18 °C). The developmental threshold temperature and effective accumulative temperature of M. similis were 9.96 °C and 231.14 Degree‐days, respectively. The average adult longevity of M. similis ranged from 5.1 (33 °C) to 26.8 days (18 °C). The maximum fecundity of the parasitoid was observed at 27 and 30 °C, which were 43.07 and 39.73 eggs, respectively. The minimum fecundity of the parasitoid was observed at 18 °C, which was 8.27 eggs. The intrinsic rate of increase (r_m) and finite rate of increase (λ) of M. similis were the highest at 30 °C. The net reproduction rate (R₀) was the highest at 27 °C and 30 °C, which were 44.34 and 40.39, respectively. We concluded that temperatures in the range 27–30 °C are the most suitable for development and reproduction of M. similis. Our study provides detailed basic information for development and reproduction of M. similis under different temperature conditions.
