The female insect is black and shiny, and the male insect is light brown and dull. It is oval, about 35 mm long, with a small head and hidden on the ventral surface of the chest. The head has a pair of antennae about 20 mm long, and the compound eye is very large and surrounds the outside of the antennae.
The female insect has no wings, and the male insect has wings. It often moves in the soil at the root of residential walls.
feeding experiment
300g of Eupolyphaga sinensis larvae aged 45-60 days were selected and randomly divided into 3 groups, with 65438 000g in each group. Under the same conditions, the experimental group 1 was fed with wheat bran, the experimental group 2 was fed with fermented material, and the experimental group 3 was fed with wheat bran+fermented material. The experimental period is 2.5 months.
Results The experimental results showed that the feed ratio of experimental group 3 was the most favorable for the growth and development of Eupolyphaga sinensis, followed by experimental group 1 and experimental group 2. Conclusion Using the feed formula of three experimental groups, the weight gain effect of Eupolyphaga sinensis nymph is obvious.
