Clover fish, also known as scissors fish, carp, whitebait, anchovy and so on. , a primitive wingless insect, belongs to trilobite family, with about 250 species known all over the world and more than 20 species known in China. This insect is not only a moth stored indoors, but also an important pest of archives, books and cultural relics in libraries around the world.

Generally, this insect has 1 generation every year, and it only takes 3 months for each generation under suitable temperature conditions. Adults can lay eggs after mating, and the eggs are scattered in the gaps of boards, books and documents. Each female lays 6~ 10 eggs. After 35~40 days of incubation, the hatched nymphs can feed. I like dark and damp, hiding in the cracks of my master during the day and coming out at night. Sexually lively and agile. You can see it all year round in a warm room. Inactive when the temperature is below 4℃. Adults have strong hunger tolerance, and can survive for 300~3 19 days without eating, which is harmful to stratified feeding. The optimum temperature for growth and development is 22~28℃, and the optimum humidity is 75~95%.

1. Breeding environment

The breeding grounds of clothing fish are bookcases, bookshelves, book bundles, floor seams and gaps between old books. Carp has negative phototaxis, so it often hides in the dark and comes out at night. Carp is sensitive to temperature and humidity. The suitable environmental temperature for carp breeding is 65438 06℃ ~ 30℃, and the relative humidity is 75% ~ 95%. When the temperature and humidity are not suitable for the breeding of sweater fish, clothing fish will migrate to an environment with suitable temperature and humidity.

2. Eating habits

Carp has a wide range of recipes, such as grain, finished grain, Chinese herbal medicine, organic matter in indoor dust, photos, paper, paste, glue, cotton cloth, animal fur, silk fiber, human dander, etc., all of which are rich in protein, sugar and trace elements. The feeding characteristics of Armillaria mellea larvae and adults are similar, and foods rich in sugar are more attractive to them. ? [2]?

breed

Carp has a strong reproductive ability, mating takes place at night, and males produce sperm cells in reproductive gaps. Female insects ingest sperm cells and complete fertilization in the body. If the temperature and humidity are suitable, females will choose hidden crevices to lay eggs. The incubation time varies with the ambient temperature. Catfish takes about 4 ~ 6 months from larva to adult. It takes about 1 ~ 3 years for larvae to develop into adults when the temperature changes frequently or the temperature is too low. The development of carp is semi-metamorphosis. It takes 8 times from larva to adult, and it still molts in adult stage, reaching 19~58 times, and its life span is about 2 ~ 8 years.
