真菌蚊蚋是一种世界性的害虫，栖息在富含有机物的环境中，包括蘑菇栽培基质，导致食用菌的大量生产损失。为了推广一种非杀虫防治策略，我们评估了成虫对两种腐生真菌菌株黄曲霉和圆形毛霉的行为反应。(1)从寄生底物和6种食用菌中分离得到。结果表明：6种食用菌中，凤仙花对平菇的吸引力最大；(b)雄性和雌性对圆叶田鼠的吸引力显著高于黄斑田鼠和黄斑田鼠；(c)成虫呈动态吸引趋势，随培养时间的不同而变化，其中雌虫最多（平均为78.6%）；(d)以圆形圆霉菌丝培养物为食的幼虫可以完成整个生命周期，而以非真菌或黄斑圆霉为食的幼虫不能存活。这些结果表明，在食用菌栽培中，利用推拉策略对圆叶霉进行生物防治是有潜力的。
The fungus gnat Bradysia impatiens (Johannsen) is a worldwide pest inhabiting organic-rich environments, including mushroom-cultivation substrates, which leads to massive production losses of edible mushrooms. To promote a non-insecticidal pest control strategy, we evaluated adult behavioural response towards two saprophytic fungal strains Aspergillus flavus Link and Mucor circinelloides Tiegh., isolated from B. impatiens-inhabiting substrates and six edible mushrooms species. Our results indicated that (a) B. impatiens was most attracted to the oyster mushroom Pleurotus ostreatus among all six edible mushrooms; (b) males and females demonstrated a significant attraction for M. circinelloides over A. flavus and P. ostreatus; (c) adults demonstrated dynamic attraction tendencies that varied with the culture periods of A. flavus and M. circinelloides, wherein females represented most (mean = 78.6%) of the attracted individuals; and (d) larvae that fed on mycelial cultures of M. circinelloides could complete their entire life cycles, but larvae could not survive on a non-fungal or A. flavus diet. These results demonstrate the potential for the development of M. circinelloides in a push-pull strategy to biocontrol this pest in edible mushroom cultivation.
