Earthworms (earth yuan)'s predators and their control
Earthworms (earth yuan) are the main enemies of earthworms, ants, mice, poultry, birds, rats and other women. 1. 螨 (1) The endangered locust is mainly a whitefly, which is a species of earthworm that grows in deteriorating feed or rotted ground maggots (earth yuan) in the rainy season with high temperature and high humidity. Easy to happen. Earthworm worms (earth yuan) leftover feed and residue can easily breed maggots in the environment of 20-25. The aphids are very fertile and reproduce 1 generation every 14-16 days. Each female quail can lay eggs. More than 200 grains can easily cause harm.The whitefly's larvae and adults parasitize in the internodes of the chest, abdomen, and leg base of the earthworm (earth earthworm), and bite the body of the earthworm (earth yuan) and eat it. The nymphs and nymphs that are being molted in the earthworm locust often cause a large number of deaths of earthworm locusts (Tuyuan) if they are not eliminated in time. (2) Prevention and control methods 1 Regular inspections, such as the surface of cultured soil When white creeping piles of small clams are removed immediately, all cultured soil is taken out and discarded, or exposed to the sun in the hot sun to kill whiteflies, and the earthworm mites (earth soil) are all sieved and replaced with new breeders. Do not place crops such as cottonseeds and rice straw near the rearing ponds to prevent the parasited locusts from crawling into the pond; feeds should not be fed too much, and the remaining feed residue, earthworm corpses, and egg sheaths must be promptly removed. (3) Killing mealworms, using oil cakes, meat, and bones as baits and putting them into the pool every day, every other day Take 1-2 hours and take it out once, and then attach the above-mentioned cockroach to death with boiling water.The effect will be better several times in succession.It can also be used to burn the cocoon on the surface of the pool wall and culture soil during the daytime.4Medicine control.40% available Dimethoate emulsion 2000 times spray Nichi surface, spraying once every 5-7 days, even spray 3N4 times have a certain effect (but the liquid can not be sprayed on the body).5 found earthworms with earthworms (earth yuan), The mouth can be processed into finished products.6 Improved feeding methods: Bran and rice bran are soaked in boiling water or cooked in a pan and then fed to avoid food carry.2. A species of crustacean, which often moves around the surface (surface) and wall of the cultured soil in aquaculture ponds, and feeds on the feed of earthworms (earth elements) to endanger young nymphs. (2) Control methods 1 Do not put straw Grass litter and other debris are brought into the culture tank to eliminate the breeding ground of the rat. 2 It is found that there is a rat woman that can be caught by hand. If the rat is in a hole outside the pond, water can be forced to climb out to capture it. The trichlorfon solution is sprayed around the culture ponds. 3. Ants can ditch the water around the breeding pond to prevent ants from invading. If ants are found in the pond, they can be baited out of the pond by meat bones, oil sticks, etc. In addition, chickens, ducks, cats, rats, geckos, spiders and other predators, in addition to pits, pools, pits, pool walls, Door gaps and other gaps should be blocked in good time; on hot days, pits and pools should be covered with lead-wire woven yarns to facilitate ventilation; geckos and spiders can also be captured manually.
