1. Breeding pond construction: The specifications of the breeding pond are 300cm long, 200cm wide and 200cm deep. The bottom is covered with loam, then covered with humus soil and decomposed and fermented horse manure or wheat straw, and finally sprinkled with Layer corncobs or straw. 2. Seed acquisition and release: From April to May and September to October every year, use a flashlight or black light to trap adults in the wild (such as farmland), then screen and release them into the pond. 3. Feeding: Feed in the evening. Green feed should be fed every day, and concentrated feed should be fed every 1-2 days. Feed small amounts more often.
1. Construction of breeding pond
1. Use bricks to build the breeding pond, and then use cement to smooth the surrounding and bottom. The specifications are 300cm long, 200cm wide and 200cm deep.
2. Lay a 100cm thick layer of loam at the bottom of the breeding pond and compact it slightly to provide an environment for the mole crickets to overwinter and lay eggs.
3. Fill in humus soil or soil containing farmyard manure, the thickness is about 20cm, and it needs to be moist and loose (adapting to the mole cricket's habit of running wet but not dry, loose and not hard).
4. Sprinkle a layer of decomposed and fermented horse dung or cow dung, crushed wheat straw, and rice bran on the surface to serve as an active layer and protective layer for the mole crickets to dig tunnels, forage, and find mates. mating.
5. Finally, sprinkle a layer of corn cobs, straw, or long wheat straw, and cover the pool mouth with an iron gauze cage for shade and heat preservation to prevent mole crickets from escaping.
2. Seed acquisition and release
1. Acquisition time: capture adult mole crickets in April-May and September-October each year.
2. Seed acquisition method: Take advantage of the strong phototaxis of mole crickets and use flashlights or black lights to trap adult insects in the wild (such as farmland).
3. Release: Screen the trapped mole crickets to select high-quality individuals with complete limbs and vitality, and then release 10 pairs of mole crickets per square meter.
3. Feeding
1. Food types: Common foods that can be used to feed mole crickets include wheat seedlings, millet seedlings, corn, sorghum, young leaves, melon peels, vegetable leaves, etc. Green feed, cooked and sun-dried grains, fried bean cakes, peanut cake residue, wheat bran and other concentrated feeds.
2. Feed processing: Before feeding the concentrated feed, it is best to process it (prepare 5kg dry grass powder, 0.5kg fried wheat bran, 50g dry yeast, 1kg fried bean cake powder, 1.5L of water, mix and stir into a thick paste, press into pancakes, cut into small pieces, dry and store in the sun), which can effectively reduce the occurrence of mildew and other problems.
3. Feeding method: Feed in the evening, with green feed fed every day and concentrated feed once every 1-2 days (concentrated feed needs to be crushed into rice grain size before feeding) , invest less and more.
4. Feeding amount: The daily feeding amount should be such that it can be eaten all on the same day and there will be no leftover when checking the next day.
4. Management
1. If it is Oriental mole cricket, harvest it once a year. If it is North China mole cricket, harvest it every two years.
2. When the temperature of the breeding pond is too high, splash water around the breeding pond to cool down. When the breeding pond is too dry, sprinkle an appropriate amount of water into the breeding pond to increase the humidity. In winter, windproof facilities are set up and straw is laid in the pool for insulation.
3. Harvesting method: In spring, use a large-hole sieve to sift the 20cm-deep humus soil in the pond, remove the adult insects, and retain some of the high-quality mole crickets as seed insects.
4. If there is a lot of insect feces in the soil or there are clumps, parasites and mites, the soil should be replaced in time.
