Temperature is a key environmental factor that influences mosquito phenotypic traits and the effectiveness of vector control strategies. () has shown promise as a microbial biocontrol agent due to its insecticidal properties; however, its effects on mosquitoes under different environmental conditions are still unexplored. This study investigated the effects of (strain WHk23) exposure on the life history traits of at two temperature conditions (20 °C and 30 °C), focusing on development, longevity, and reproductive fitness. Results showed that temperature significantly affected mosquito development and longevity, with faster development and shorter adult longevity observed at 30 °C compared to 20 °C. Exposure to further accelerated larval development and reduced adult emergence, with the effects being more pronounced at 30 °C than at 20 °C. Exposure to reduced adult longevity regardless of temperature. In addition, -exposed females had larger body sizes but lower fecundity and fertility, suggesting that exposure may cause physiological stress that disrupts reproductive processes. These findings highlight the importance of considering environmental factors in mosquito control programs while reinforcing the efficacy of as a sustainable biocontrol agent under a variety of environmental conditions.
温度是影响蚊子表型特征和病媒控制策略有效性的关键环境因素。（）由于其杀虫特性，已显示出作为微生物生物防治剂的潜力；然而，其在不同环境条件下对蚊子的影响仍未得到探索。本研究调查了在两种温度条件（20°C和30°C）下，（菌株WHk23）暴露对（某种蚊子）生活史特征的影响，重点关注发育、寿命和繁殖适应性。结果表明，温度显著影响蚊子的发育和寿命，与20°C相比，30°C时发育更快，成虫寿命更短。暴露于（该微生物）进一步加速了幼虫发育并减少了成虫羽化，30°C时的影响比20°C时更明显。无论温度如何，暴露于（该微生物）都会缩短成虫寿命。此外，暴露于（该微生物）的雌性蚊子体型较大，但繁殖力和生育力较低，这表明暴露于（该微生物）可能会引起生理应激，从而扰乱生殖过程。这些发现突出了在蚊虫控制计划中考虑环境因素的重要性，同时也强化了（该微生物）作为一种在各种环境条件下可持续的生物防治剂的功效。
