Control of Pleurotus ostreatus with Pleurotus ostreatus
Through investigation, it has been found that the pests that harm edible mushrooms, especially oyster mushrooms, this year are mainly Pleurotus ostreatus and Pyralidae, both of which belong to Diptera. The former is the dominant pest species in the country and endangers larvae. The head is black, chest and abdomen are milky in white, a total of 12 knots. The newly hatched larvae have a body length of about 0.6 mm, and the mature larvae are 4.6 and 5.5 mm. In a temperature range of 13 to 21°C, about 4 to 7 days are passed. Can be hatched into larvae, larval period of 9 to 17 days. Many larvae live on cultivated bacteria bags, eating hyphae and causing great harm. The fungal mosquitoes are tiny and delicate mosquitoes. The larvae are spindle-shaped. The epidermis is transparent and has no feet. The body color is orange-red, orange-yellow, light-yellow, white due to different environments and developmental periods. White plover or small red plague, mainly larvae, because the larvae are mainly breeding, the reproductive cycle is very short, and one generation can be bred for one week in the mushrooming period, so it can occur in a large amount in a short period of time. When the population density is large, piles can be seen. In larvae, larvae can drill into the epidermis of fruiting bodies at low temperatures. Prevention measures: First, pay attention to the health of the mushrooming places and bactericidal establishments. The mushroom house doors and windows should be installed with insect nets to timely remove the waste of edible fungi; second, the culture materials should be mixed with high efficiency and low toxicity before bagging or going to bed. Insecticides, usually beta-cypermethrin, phoxim, etc., are generally diluted to 2000-3000 times. During the germination period, insecticides should be sprayed continuously at the bacteria-producing sites. At present, the main agents are beta-cypermethrin and diosmin. Insects, mushrooms, net, mushroom net, etc., in the production of Pleurotus ostracodus should be used to eliminate the use of dichlorvos, otherwise it will lead to severe deformity of Pleurotus ostreatus fruiting body; The third is in the mushroom bag and mushroom bed insecticide mosquito can be used when spraying insecticide Agents and the use of aluminum sulphate fumigation, per cubic meter can be used 2 to 3, should pay special attention to safety; Fourth, in the cultivation and management, it should promptly remove the rot bacteria, control pests in the material propagation, but also pay attention to mushrooms The humidity of sheds and culture materials should not be too large, otherwise it will cause the decay of mycelium and mushroom bodies and cause an opportunity for mushroom mosquitoes to occur.
