Mushroom gnats
Mushroom gnats do the most damage during their larval stage. Besides boring and feeding on the surface of the growing medium, some also spin webs that cover the mushroom buds, preventing the fruiting bodies from growing normally. Control method: after harvesting, spray with trichlorfon at a 500-800 times dilution, and at the same time fit nylon mesh over the doors and windows of the mushroom shed to keep adult gnats from flying in to lay eggs and breed and cause damage.
