How to raise yellow mealworms in basins? Master these methods and it's easy

    Raising yellow mealworms in basins is suitable for farming with a monthly output of 10 kg. It does not require a full-time person to feed them; you can do it in your spare time. The rearing equipment is simple and economical (such as old washbasins, iron boxes, wooden boxes, etc.). As long as the container is intact, has no breaks or leaks, and has smooth inner walls so the insects cannot escape by crawling out, it is fine. 

If the inner wall of the box is not smooth, you can stick a ring of tape around it to prevent the insects from escaping. In addition, you need 1 sieve of 60 mesh. 

1. After obtaining the insect stock, first carefully select them, choosing individuals that are large, uniform, vigorous, and bright in color, and raise them in a dedicated basin. A container the size of an ordinary washbasin can raise 0.3-0.6 kg of larvae. 

2. Put feed into the basin, such as wheat bran, cornmeal, etc., and at the same time put in the larval stock. The feed should be 10-20% of the insect weight. After 3-5 days, when the insects have finished eating the feed, sieve out the insect droppings with a 60-mesh sieve. Continue to add feed. Appropriately add some water-containing feed such as vegetables and melon and fruit peels. 

3. When the larvae pupate, promptly pick out the pupae and store them separately. After 8-15 days, the pupae emerge as adults. Lay a sheet of newspaper on the bottom of the basin or box, then spread a layer of fine feed about 1 cm thick on the paper, and place the emerged adults on the feed. At 25°C, adults begin mating and laying eggs about 6 days after emergence. Yellow mealworms are gregarious insects, and mating and egg-laying require a certain population density, with 1500-3000 insects per sq m of insect box. During the adult egg-laying period, feed them better concentrated feed. In addition to mixed feed plus multivitamins, also add an appropriate amount of water-containing feed, such as vegetable leaves and melon and fruit peels. 

4. When adults lay eggs, they extend the ovipositor under the feed and lay the eggs on the paper. After 3-5 days, the egg paper is covered with insect eggs, and new egg paper should be replaced. Collect the removed egg paper, place it in a basin according to the same date, and wait for it to hatch. At a temperature of 24-34°C, it can hatch in 6-9 days. Newly hatched larvae are very soft, so try not to touch them with your hands to avoid harming them. 

5. Put the hatched larvae together for rearing. After 15-20 days, when the feed in the basin is basically eaten up, you can sieve out the insect droppings for the 1st time. Use a 60-mesh sieve screen to sieve the insect droppings. After that, sieve out the insect droppings once every 3-5 days, and at the same time feed once, with the amount of feed added based on being eaten up in 3-5 days. 

Note: Feeding vegetable leaves or melon and fruit peels should be done 1 day before sieving the insect droppings, and the amount added should be based on being completely eaten by the larvae overnight, or sieve out the insect droppings first before feeding vegetable leaves and melon and fruit peels. The next day, as soon as possible, remove the uneaten.
