Dengue fever is one of the most rapidly spreading arthropod-borne diseases. Diurnal vectorial properties of Aedes albopictus contribute to the dispersion of the dengue viruses. Frequent and injudicious use of synthetic insecticides led to the evolution of resistant phenotypes in Ae. albopictus which necessitates the search for an alternative of current control strategies. Developing a long-lasting and environmentally safe tactic based on knowledge of ecology and population dynamics of Ae. albopictus is critical. Therefore, with a view towards biological control and ecology, the effect of entomopathogenic fungi (EPF) Beauveria bassiana on filial and first filial generations of Ae. albopictus were studied. Investigations showed 87.5% adulticidal activity leading to altered fecundity and adult longevity in a filial generation. The lethal (LC₅₀) and sublethal (LC₂₀) concentrations of B. bassiana were applied to filial generation (F₀) to study demographic parameters in the first filial generation (F₁). Results showed reduced net reproductive rates (R_o) intrinsic rate of increase (r), and mean generation time (T) compared to uninfected controls. Prolonged larval and pupal duration were observed followed by reduced longevity of male and female adults. Fecundity in the first filial generation was significantly changed with the lethal and sublethal concentrations of B. bassiana. Thus, it is concluded that B. bassiana has the potential to play a vital role in integrated mosquito management strategies.

白僵菌对白纹伊蚊种群的致死、亚致死和跨代影响评估（库蚊科：双翅目）


登革热是传播最快的节肢动物传播疾病之一。白纹伊蚊的昼夜传播特性有助于登革热病毒的传播。频繁且不明智地使用合成杀虫剂导致了伊蚊抗性表型的进化。白纹伊蚊，这使得有必要寻找当前控制策略的替代方案。基于生态学和伊蚊种群动态知识，制定持久且环境安全的策略。白纹伊蚊至关重要。因此，从生物防治和生态学的角度，研究昆虫病原真菌(EPF)白僵菌对白蚊子代和子代第一代的影响。对白纹伊蚊进行了研究。调查显示，87.5% 的杀成虫活性导致子代的繁殖力和成虫寿命发生改变。将白僵菌的致死浓度（LC ₅₀ ）和亚致死浓度（LC ₂₀ ）应用于子代（F ₀ ），以研究第一子代（F ₁ ）的人口统计参数。结果显示，与未感染的对照相比，净繁殖率（ R _o ）、内在增长率（ r ）和平均世代时间（ T）降低。观察到幼虫和蛹的持续时间延长，随后雄性和雌性成虫的寿命缩短。第一子代的繁殖力随白僵菌致死和亚致死浓度的变化而显着变化。由此，得出结论： B. 白僵菌有可能在综合蚊子管理策略中发挥至关重要的作用。
