How to choose the right feed for ground beetle (Eupolyphaga sinensis) farming

The ground beetle has very omnivorous feeding habits, and feed sources are wide-ranging. Feed includes both plant-based feed and animal-based feed. Among them, plant-based feed can be further divided into green feed, grain feed, and cake (meal) feed, and it is the main feed for raising ground beetles.

Plant-based feed Green feed Lettuce, water spinach, rapeseed, pumpkin, luffa, winter melon, watermelon rind, potato, carrot, various wild vegetables, forage grass, tree leaves, the stems and leaves of crops, and the peels of fruits such as apples and pears can all be used as feed for ground beetles. Among them, mulberry leaves, dandelion, lettuce, pumpkin, carrot and others are the green feeds most commonly eaten by ground beetles. Grain feed includes wheat bran, rice bran, sorghum, corn, and others, and these are also currently the main feeds for feeding ground beetles. Among them, wheat bran is the main one, and generally it can all be fed raw. If it is stir-fried, steamed, or blanched until cooked and slightly fragrant, ground beetles like to eat it even more, and the feeding effect is even better. Cake (meal) feed such as soybean cake, tofu residue, peanut cake, sesame cake, rapeseed cake, and others. This type of feed is rich in protein. Although it is not the main feed, it is not dispensable either. Cake and meal feed has a relatively strong promoting effect on the yield of ground beetles. Animal-based feed includes fish meal, bone meal, silkworm pupa meal, small fish, small shrimp, various animal scraps, earthworms, and others. Adding this type of feed can promote rapid growth of ground beetles and shorten the farming cycle, and it is a very excellent feed. Commonly used feed formulas Larva feed: 65% bran, 20% soybean cake or soybean powder, 10% green feed, 5% fish meal or bone meal. Third-instar ground beetle feed: 40% wheat bran, 10% cornmeal, 5% soybean cake or peanut cake, 40% green feed, 5% fish meal or bone meal. Ground beetles at the ninth instar and above: 30% wheat bran, 10% cornmeal, 10% cake-type feed, 45% green feed, 5% fish meal. In short, the feed for ground beetles is diverse, and the formula must also be grasped flexibly. Only with reasonable combination and scientific formulation can a good nutritional foundation be laid for the growth and development of ground beetles, and only then can high yield and high efficiency be achieved later.
