Special economic animal earthworm predator control method
1． Natural enemy animal control
Earthworms have more natural enemies, generally omnivorous, carnivorous and parasitic animals, such as centipedes, centipedes, mites, spiders, parasitic flies, ants, cockroaches, green earthworms, toads, snakes, sparrows, thrushes, magpies, crows, voles and so on are its natural enemies. Cage nets can be used to prevent natural enemies of earthworms from entering the pool and bed, and when adding materials, it is also forbidden for ants to enter the pool and bed with the material, use watermelon peels, fruit cores or meat bones after people eat to trap ants, use flour to trap mites, and use larks to spray ants, cockroaches, etc. Rats are caught with rat clips or cages, and birds such as sparrows are trapped with rice or wheat grains. In addition, ditches are dug around the breeding bed to guard against predators.
2． Black-eyed mosquito control
The black-eyed mosquito is a genus of dipterocarp mosquitoes, with a tiny body, about 2 mm long, and gray-black. Summer is the peak of the insect's activity, and its population has decreased significantly after mid-September. The main hazards are to crush the base material, reduce the amount of stomatal pores, eat microorganisms so that earthworms can not move to the surface, and seriously reduce the spawning rate and the survival rate of young earthworms. Control uses 400 times the net spraying of pests on the surface of the breeding pond. It should be sprayed when the earthworm has not climbed to the surface, and it should be fast, only a trace amount of it is swept away, otherwise it is harmful to the earthworm. Secondly, the pool can be soaked in water to allow the adult worms to float up and remove. It can also be hung by the pool with a light, a small stove under the lamp, and the adult insects will fly up and be smoked by the heat of the stove and die.
3． Red gall mosquito control
The harmful effects of the red gall mosquito are the same as those of the black-eyed mosquito, but to a more severe extent. The red gall mosquito is long, 0.8 to 1 mm, bright orange, and the compound eyes are large and black. The mosquitoes are extremely adaptable and multiply all year round. The worm is very fond of rotting ferments, and the base material is a good place for its reproduction and growth, so within 1 week, it can cause the entire earthworm pond to turn red, resulting in no earthworms on the upper layer of the earthworm pond. Insect pests seriously affect the amount of eggs laid by earthworms, but also affect the normal eating and activities of earthworms, destroy the entire breeding environment, and limit the growth of earthworms. Gall mosquitoes also carry and transmit the virus. The control method is the same as the control of the above-mentioned "black eye fungus mosquito".
4． Flea control
Flies can consume earthworm feed in large quantities, seriously polluting and even destroying the living environment of earthworms. It is about 8 mm long and gray-black. From May to October, the activity is the peak period, the insect is good at jumping, and the phototropism is strong. The larvae swallow enzymatic nutrients in large quantities. It seriously affects and hinders the spawning of seed earthworms, causing a significant decline in the reproductive rate and even causing the collapse of the population. The control method is the same as the control of the above-mentioned "black eye fungus mosquito".
5． Mealymouth control
There are many kinds of mealymous mites, and the most harmful are carrion mite and wood-loving mite. The body of the pink mite is round and white, and the limbs are small and difficult to see. It often feeds on fungal organic decompositions, which is extremely harmful to the closed edible hyphae and binders, so when the edible mushroom waste base material is used as the earthworm base material, it will multiply in large quantities, causing the earthworm population to escape and inhibit spawning. Prevention and control can be sprayed on the surface of the breeding bed 1-2 times with 0.05% long-acting mosquito repellent, which can be completely killed.
6． Jumping insect control
Jumping insects, commonly known as jumping insects, there are many types, common mushroom wart jumping insects, proto-jumping insects, blue jumping insects, mushroom jumping insects, black horn jumping insects, black flat jumping insects and so on. Jumping insects are 1 to 1.5 mm long, shaped like fleas, and mostly move on humus such as dung piles, carrion, edible mushroom beds, and slag piles. Its tail is pointed, with the ability to bounce, and the height of the bounce is 2-8 cm. Its body surface is oily and can float on the surface of the water. The larvae are adults, white in color, and peel off their skin after hibernation and turn silvery gray. The eggs are translucent white bulbous and are laid on the surface. Jumping insects mainly gather on the surface of the breeding pond to nibble on the base material into a powder, and can also directly bite the earthworm to death. The control method is the same as that of "powder mite".
7． Ape leaf insect control
Ape leaf insect is one of the main pests of cruciferous vegetables, mainly large ape leaf worm and small ape leaf worm, the two kinds of ape leaf worm are similar in shape. In general, adult insects overwinter at 4-8 cm of saprophyll leaves and loose soil or dive into saprophylls below 15 cm or soil to sleep in summer, and are frequently active on weekdays. Larvae, like adults, have a suspended animation habit and are very confusing, mainly damaging to the substrate and directly injuring earthworms or eggs. The control method is the same as the control of the above-mentioned "jumping insects",
