Control methods of Ganoderma lucidum mosquitoes

Bacterial mosquitoes, also known as Zhi mosquitoes, harm more than 10 species of Ganoderma lucidum mosquitoes, of which late-eyed mosquitoes and small mosquitoes are more common. The adults of Ganoderma lucidum are dark brown, with dark head color and a body length of 2 mm. The adults of small mosquitoes are light brown, with a dark head and a body length of 4mm to 6mm. Let's take a look at the control methods of Ganoderma lucidum mosquitoes.

Occurrence regularity of Ganoderma lucidum mosquitoes

The peak periods of mosquito adults are from March to April and from October to November, and they have strong decay and phototaxis. Most of the eggs of adults are laid on the gap surface of the culture material and covered with soil, and rarely on the sesame body. The larvae like to move at the temperature of 15-28 ℃ and grow well. Most of the mature larvae pupate in the gaps in the soil or in the culture material. Bacteria and mosquitoes eat miscellaneous, like humus, and often live in unclean places, such as garbage, waste, dead Ganoderma lucidum and old roots.

Harmful symptoms of Ganoderma lucidum mosquitoes

The eggs, larvae and pupae of the mosquitoes mainly enter the bacterial bed with the culture material or covered soil, while the adults fly directly into the sesame room to reproduce and lay eggs. Mosquito adults do not directly harm Ganoderma lucidum, but often carry bacteria, nematodes and mites in and out of Zhi Fang. The larvae endanger the mycelium and fruiting body of Ganoderma lucidum, and mostly crawl between the hyphae, making the culture material black, loose and sunken, and the hyphae change from white to yellowish brown, which makes it difficult to produce Ganoderma lucidum. After the emergence of Ganoderma lucidum, the larvae feed from the base of the sesame stalk, and gradually eat into the interior of the Ganoderma lucidum, in which the primordia and young Ganoderma lucidum suffer the most. The development of young Ganoderma lucidum in the parts with a large number of insect population will be inhibited, and the infected Ganoderma lucidum will show leathery or cluster hollow stalk after browning, so that the affected Ganoderma lucidum will become soft and spongy, and finally rot.

Control methods of Ganoderma lucidum mosquitoes

1. Do a good job in environmental hygiene inside and outside the sesame room in order to effectively reduce the source of insects.

2. 60 mesh screen should be installed on the doors, windows and vents of the Zhifang room, and it is best to apply long-term drugs to kill mosquitoes and flies to prevent the adults of late-eye bacteria and mosquitoes from moving into the room.

3. During the cultivation period, the daily management of Zhi Fang should be arranged during the day as far as possible. Under the principle of ensuring the working light, the indoor lighting should reduce the opening times and time. During the adult activity, black light or incandescent lamp is used to trap and kill day and night to reduce the number of adults and control the number of eggs laid.

4. Before the culture material enters the house, 40% diazinon emulsion can be combined with turning pile and mixed material, and the film can be sealed for 1 / 2 days, 0.1 kg per ton of culture material, and the 1000-1200 times liquid of the medicine can also be used to spray the sesame room, bed frame and covering soil. During the peak period of adults, 1000 times of dichlorvos can be used to spray space. When larval damage occurs in the bacterial bed, 2.5% cypermethrin 1500-2000 times or 50% malathion 1500-2000 times can be sprayed on the surface of the bed without Ganoderma lucidum.
