Pest - MUSHROOM FLIES
Most mushrooms growers find mushroom flies to be a most challenging pest.
Mushroom flies go through seven developmental stages: egg, four larval stages, pupa, and adult. At a temperature of 76 degrees F, development from egg to adult takes approximately 21 days; at 61 degrees this takes twice as long. Adults invade mushroom buildings containing freshly pasteurized compost. They are attracted by the smell of the compost and growing mushrooms. Each female can lay up to 170 eggs in the substrate.
Emerging larvae feed on compost, destroying structure and water retention capacity that inhibits growth and reduces yields. Larvae also feed on the developing mushrooms, making them unsaleable because of the damage that occurs. The adult flies are a constant nuisance to picking staff, and are known to be vectors of harmful funguses, bacteria, nematodes, and mites.
Yellow sticky traps (HORIVER) are effective in detecting and monitoring adult flies. Effective control of mushroom flies is possible with the Koppert products listed below.
