Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an invasive and destructive beetle that causes extensive damage to ash trees in North America. The entomopathogenic fungus Beauveria bassiana Vuillemin is considered as an effective biological control agent for EAB adult populations. Using an autodissemination device with a fungal isolate of B. bassiana, our research aims to investigate the possibility of horizontal transmission of the fungal disease from infected to uninfected EAB adults during mating. Results show that the efficiency of fungal transmission is significantly related to the sex of EAB carrying the fungal pathogen. EAB males are the promising vector to transmit mycosis to their partners during mating. Results strengthen the potential of the fungal autodissemination device as a powerful biological strategy to control EAB populations.
外来入侵种榆绿毛萤叶甲（EAB），扁叶甲属平腹小蜂，是一种具有极强破坏性的甲虫，会对北美的白蜡树造成广泛的损害。球孢白僵菌（一种真菌）被认为是一种有效的生物防治剂，可以控制 EAB 成虫种群。我们使用一种具有球孢白僵菌真菌分离株的自动传播装置，旨在研究在交配过程中，真菌疾病是否可能从感染的 EAB 成虫传播到未感染的 EAB 成虫。结果表明，真菌传播的效率与携带真菌病原体的 EAB 的性别显著相关。EAB 雄性是在交配过程中将真菌感染传播给它们的伴侣的有前途的媒介。研究结果增强了真菌自动传播装置作为一种强大的生物防治策略来控制 EAB 种群的潜力。
