Device and method for breeding Trichogramma

Abstract

The invention relates to a device for breeding Trichogramma, which comprises a Trichogramma breeding box, Trichogramma breeding frames and egg carrying boards. The Trichogramma breeding frames are arranged in the Trichogramma breeding box; the egg carrying boards are arranged on the Trichogramma breeding frames; the Trichogramma breeding box comprises a bottom plate, a top plate and side walls; the side walls and the bottom plate are lightproof; one side of the top plate is provided with a light-transmitting board and the other side of the top plate is provided with a lightproof board; guide rails are arranged in the Trichogramma breeding box; and the Trichogramma breeding frames translates below the top plate from the side of the light-transmitting board to the side of the lightproof board by the guide rails. The invention also relates to a method for breeding Trichogramma by the breeding device. The device and the method have the advantages of simple structure, simpleness for operation, high breeding efficiency and improvement on the breeding conditions and belong to the field of insect breeding.

Description

technical field [0001] The invention relates to an insect breeding device and method, in particular to a Trichogramma breeding device and method. Background technique [0002] Trichogramma is a parasitic natural enemy widely propagated and utilized by countries all over the world. It can parasitize the eggs of various Lepidoptera, Coleoptera, Diptera, Homoptera, Hymenoptera and other insects, and eliminate pests at the egg stage . The natural host eggs for large-scale reproduction of Trichogramma mainly include rice moth eggs, wheat moth eggs, tussah silkworm eggs and Mediterranean mealworm eggs, etc., and these eggs are all small eggs. The cost of artificial large-scale propagation of rice moth (or wheat moth) is relatively low, and the source of raw materials is wide. The technology of using rice moth (or wheat moth) eggs to breed Trichogramma is widely used. [0003] However, the current methods and equipment for breeding Trichogramma by using rice moth eggs are relativ...

AI Technical Summary

Problems solved by technology

The main disadvantage of this method is that the parasitism rate is low. Due to the small gap between the eggs of the rice moth, the Trichogramma is not allowed to pass through smoothly, and the parasitism rate of the bottom eggs is often less than 20%.

Adopting this technology to breed egg parasitoids has the following disadvantages: 1. This technology uses cages for breeding, with light transmission on all sides, mainly for bee species such as flat-bellied wasps, and is not conducive to the parasitism of Trichogramma

2. The egg card is to stick the eggs on the paper. After the parasitization, the eggs cannot be swept down and cannot be reused, and the storage and transportation need to be together with the paper, which is not convenient for storage and transportation; when the parasitic effect is not good, the entire egg card becomes invalid. cause waste

3. This technology cannot solve the problem of bee sweeping, and the efficiency of bee breeding is low
