Ganoderma lucidum pest: fungus gall midge

Fungal gall midge (MycophilafungicolaFelt), also known as mushroom gall midge, mushroom. Belongs to Diptera, gall mosquito family.

1. Morphologically and sexually small adults are small, about 1 mm long. The head, chest and back are dark brown, and the others are taupe or orange. Small head, large compound eyes, left and right connected, antennae slender and beaded, 11 nodes, each node has circular radial fine hairs, male antennae longer than females, wings broad and hairy. The ventral end of the female is thin, and the male has a pair of clamp-like grips. The egg kidney shape is about 0.3 mm long, milky white to light brown. The larvae are maggot-shaped, 13-segmented, legless, orange, yellowish or white. The pupa is naked, with an average length of 1.07 mm and a width of 0.27 mm, orange-red, with 2 hairs at the top, which are respiratory tubes.

Both adults and larvae have phototaxis, and the population density is high in brighter places. The larvae like to be wet, move freely in the damp places, and can survive in the water for many days. Under the condition of high temperature and high humidity, reproduce one generation every week. Therefore, it can occur in a large number in a short time.

two。 The mycelium and fruiting body of Ganoderma lucidum are harmed by larvae. During the period of infection, it was harmful in the material, and then transferred to the soil layer after covering the soil to damage the villous hyphae and fruiting body primordium. the buds yellowed and wilted and died after being injured.

3. Prevention and cure method

The main results are as follows: (1) screen should be installed on the doors and windows of the room to prevent the invasion of adults.

(2) remove waste dirt and waste, keep it hygienic and keep the environment dry with lime.

(3) when gall mosquitoes are found, 1% permethrin or 1000 times 50% phoxim is sprayed.

(4) 500 times dichlorvos solution was sprayed on the surface during disinfection treatment, covering the film to kill eggs, pupae and larvae.

(5) making use of the phototaxis of adults, install "edible fungus high voltage electrostatic insecticidal lamp" to catch and kill. Recently, Zhejiang Yuyao Edible Fungi Research Institute designed and produced a novel high voltage electrostatic insecticidal lamp according to the design of edible mushroom flying insects. The product has the characteristics of good insecticidal effect, convenient installation, safe use, low power consumption, long life, small size and so on.
