Parasitic bee, what is it?

Parasitic bees include APIs mellifera, Trichogrammatidae, and common species include Lepidoptera, Lepidoptera, Lepidoptera, Trichogramma dendrolimi, etc. The body color of parasitic bees varies from species to species, but the physical characteristics of adult bees are basically similar. Parasitic bees are completely abnormal insects, and all parasitic bees have to go through four stages of growth and development: egg, larva, pupa and adult bee.

First of all, the classification of biology

Parasitic bees are the general name of all parasitic bees in LEPIDOPTERA, mainly including the insects of Apiidae, Apiidae and Trichogrammatidae, such as Lepidoptera, Trichogramma, Trichogramma and so on. They are common parasitic bees, especially Trichogramma, which are widely used in agricultural pest control.

Second, the morphological characteristics

The body color of parasitic bees varies from species to species, but adult bees have a pair of tentacles, two pairs of wings and three feet. The body consists of head, chest and abdomen. The head is mostly kidney-shaped with compound eyes on both sides of the head. The chest is approximately cylindrical and divided into three parts. Each part has a pair of feet, the middle and rear breasts have a pair of membranous wings, and the female bee has a needle formed by fallopian tube degeneration at the end of her abdomen.

Third, growth and development

Parasitic bees are completely abnormal insects. All parasitic bees go through four stages: egg, larva, pupa and adult bee. Egg white, oval, white larva, short body, yellow-white pupa, and the body color gradually deepens with age. Head, chest and abdomen are obvious, and the main organs are obvious. They don't eat at the pupa stage, and they don't eat honeycombs.

Fourth, living habits.

1, egg parasitism

Egg parasitism means that parasitic bees lay eggs in the host eggs, and the larvae of parasitic bees feed on the host eggs and complete their development. For example, Trichogramma corn borer and Trichogramma corn borer belong to egg parasitism.

2. Larvae parasitism

Larval parasitism means that parasitic wasps lay eggs in host larvae, and parasitic wasp larvae feed on host body fluids to complete their development. For example, the aphid jumping bee and the golden bee belong to larval parasitism.

3. Pupa parasitism

Pupa parasitism means that parasitic bees lay eggs on the parasitic main pupa, and the larvae of parasitic bees feed on the parasitic main liquid to complete their development, such as thigh bees and gypsy moths.

4. Adult parasitism

Adult parasitism means that parasitic bees lay eggs on the host, and the larvae of parasitic bees feed on the host body fluids to complete their development, such as spider bees and gourd cocoons.
