Occurrence and control measures of jumping insects in mushroom house

Collembola is a common pest of mushroom. It has been found in the production of edible fungi such as Pleurotus ostreatus, Volvariella volvacea, Coprinus comatus, Lentinus edodes, Pleurotus eryngii, Pleurotus ostreatus, Auricularia auricula, Hericium erinaceus, Agaricus blazei, etc. Introduction of occurrence and control measures of springback in mushroom house.

1. The species of mushroom springworms

Mushroom common jumping insects have black horned jumping insects, yellow wart jumping insects, mushroom purple jumping insects, purple jumping insects and so on. Jumpers vary in color and individual size, but they all have flexible tails and bounce freely. The springback is oily and not afraid of water. Jumping insects occur mostly in damp old mushroom houses, often concentrated on the bed surface or in the dark. It mainly bites the fruiting body of edible fungi, and mostly invades people from wounds or pleats. A complete mushroom body is killed for 3 days, it is not edible, let alone as a commodity. Under suitable conditions, springtails can produce 6~7 generations per year in mushroom houses and reproduce very quickly. When it happens badly, the mushroom bed seems to be covered with a layer of soot powder. Therefore, hoppers are commonly known as ash worms.

II. Growth Habits of Jumping Worms

1. Growth and reproduction. The cycle is short, the growth and reproduction of fast-growing springworms is quite active under warm (20℃--28℃) and humid conditions (air relative humidity 85%), and the reproduction speed is the fastest, which can occur 6--7 generations per year.

2, a wide range of life, omnivorous strong. Jumping insects mostly occur in mushroom houses with poor ventilation, too humid environment and poor sanitary conditions. They not only harm a variety of edible fungi in mushroom houses, but also can be seen in soil, weeds, dead leaves and livestock manure all year round. They float on the water and jump freely, especially when it clears after continuous rain.

3. Carry and spread diseases and insect pests, resulting in cross-repeated infection. The adults and larvae of springtails carry a large number of germs and mites on their body surfaces. With the springback egg feeding and other activities, springback pests and diseases also quickly spread to where they go. If the conditions are suitable, cross infection will occur, causing heavy losses to edible fungi production.

III. Control measures of springtail in mushroom house

1. Clean and hygienic, eliminate insect sources

Thoroughly remove the garbage inside and outside the seed production site and cultivation site, especially without accumulated water, to prevent the breeding of springtails.

Jumping insects like warm and humid but do not tolerate high temperature. It is best to use fermented materials to make the temperature reach 65℃-70℃, which can kill adults and eggs. Mushroom houses and covering soil can only be used after fumigation.

Mushroom doors and windows installed gauze.

2. Trap method

Jumping insects have the habit of loving water. For places where jumping insects occur, they can be trapped and eliminated with water. The specific method is: use a small basin to hold clear water. Many jumping insects jump into the water. The next day, change the water and continue to kill them with water. Several times in succession, the density of insect population will be greatly reduced.

90% trichlorfon diluted by 1000 times and a small amount of honey are mixed into trapping agent and distributed in pots or dishes. They are scattered on mushroom beds. Jumpers will jump into pots when they smell sweet. This method is safe and nontoxic, and can also kill other pests.

3. Drug prevention

Pesticides are not recommended for the prevention and control of edible fungi diseases and insect pests. Other methods should be used as far as possible, with less or no pesticides. Only when the pests are serious can they be used as a last resort.

When there is no mushroom on the bed surface, 0.2% dimethoate can be sprayed.

During fruiting period, pyrethroids can be sprayed with 150 - 200 times solution.

spray chinaberry preparation: prepare according to that ratio of chinaberry bark: wat =1:3--1: 5, evenly mixing, decocting for 1.5 hours to obtain the original medicine, dilute by 1 time when used, and using with preparation.

Fumigate with 9.9 g aluminum phosphide per cubic metre.
