Abstract：
Metarhizium anisopliae (Ascomycota: Hypocreales) is an entomopathogenic fungus considered a key factor in developing integrated management of several insect pests on a variety of crops. The predatory coccinellid, Menochilus sexmaculatus (Col.: Coccinellidae), is also an important natural enemy that must be conserved for effective aphid control. Laboratory studies were conducted under controlled conditions to investigate the interaction between M. anisopliae isolate IRN. 1 and the coccinellid predator M. sexmaculatus in combating Aphis gossypii Glover (Hem.: Aphididae). The combined application of M. sexmaculatus and M. anisopliae led to significant reduction in aphid populations. The foraging behavior of M. sexmaculatus notably facilitated the dispersion of M. anisopliae conidia to uninfected plants, resulting 54 ± 1.3% decrease in aphid density after 10 days. In both choice and non-choice experiments, female adult M. sexmaculatus to fungus-infected aphids was offered as prey and avoided as a food source during all starvation periods. However, live and dead non-fungus-infected aphids were fed upon. The result revealed the compatibility between M. sexmaculatus and M. anisopliae, which may provide a sustainable strategy for the effective management of A. gossypii in a cropping system.
摘要：
metarhiziumanisopliae（Ascomycota：Hypocreales）是一种昆虫病原真菌，被认为是对多种作物上的几种害虫进行综合管理的关键因素。捕食性球虫,甲虫（上校。：球藻），也是重要的天敌，必须保守才能有效控制蚜虫。在受控条件下进行了实验室研究，以研究分离株IRN之间的相互作用。1和球虫捕食者M.sexmaculatus在对抗棉签格洛弗（Hem。：蚜虫）。六斑马菌和金丝虫的联合应用导致蚜虫种群的显着减少。六斑分枝杆菌的觅食行为显着促进了分生孢子分生孢子向未感染植物的分散，10天后，蚜虫密度降低54±1.3%。在选择和非选择实验中，在所有饥饿期间，将雌性成年M.sexmaculatus提供给真菌感染的蚜虫作为猎物，并避免作为食物来源。然而,以活的和死的非真菌感染的蚜虫为食。结果揭示了六斑分枝杆菌和斑驳分枝杆菌之间的相容性，这可以为种植系统中棉草的有效管理提供可持续的策略。
