Occurrence Characteristics and Control Methods of Mushroom Gall Midge
I. Morphological Characteristics The gall midge, also known as the small red maggot or mushroom gnat, has adults that resemble small mosquitoes, tiny and delicate, difficult to see with the naked eye. The head, thorax, and dorsal side of the body are dark brown, while the rest is grayish-brown or light orange. Larvae can hatch from eggs or be reproduced by the mother's larvae. Each female can produce an average of more than 20 larvae. In the early stage, larvae cause damage in the substrate, resulting in sparse and weak mycelium. In the later stage, they move to the mycelium and fruiting bodies. When fruiting bodies are damaged, they first breed at the base of the mushroom stipe, then climb to the junction between the stipe and the cap, and some bore into the gills, which are eaten into scars and trails, appearing light orange-red. A single mushroom can host 20 to 30 larvae in severe cases, seriously affecting the quality and yield of mushrooms.

What are the control methods for mushroom gall midges?
I. Causes (1) Improper composting of the growing substrate. The substrate is not fully fermented, the turning of the pile is uneven, the fermentation time is too short, and disinfection is not thorough. (2) Unsuitable microclimate inside the mushroom house, such as humidity being too high. (3) Poor cultivation conditions. Growers use old mushroom racks to cultivate mushrooms and do not disinfect thoroughly after harvesting. The water source is not clean and carries diseases, pests, and contaminant microorganisms. The mushroom house has poor ventilation. II. Control methods (1) Site selection and mushroom house disinfection. The mushroom production site must be chosen in a place with dry terrain, close to a clean water source.
