Bio-ecological characteristics and control strategies of Bradysia impatiens

The bio-ecological characteristics and control strategies of Bradysia impatiens Johannsen were summarized in this study. Edible fungus and Chinese chives (Allium tuberosum) are B. impatiens’ most favored host plants for adaptability and food preference. For population growth, the most favorable growth conditions were found to be temperature 25 ℃, photoperiod L ꞉ D = 16 h ꞉ 8 h, and light intensity of 588 lx. Humidity is closely related to the living habits and behavior of insects; however, there are few known studies on this topic for B. impatiens. At present, chemicals remain the main control method for B. impatiens. Potentially better control may be possible, though, by using biological control technologies, such as entomopathogenic nematodes, predatory mites, and Bacillus thuringiensis, and physical control methods, such as high temperature solar film covering and phototaxis. In the present study, we summarize and elaborate the bio-ecological characteristics and control strategies of B. impatiens, with the aim of providing a theoretical basis for further study of B. impatiens.
