Trichogramma laid egg collecting device

Abstract

The invention discloses a trichogramma laid egg collecting device which is used for facilitating uniform distribution of trichogramma and making full use of intermediate host eggs for parasitism. Thedevice comprises a box, a partition plate frame, a plurality of partition plates and egg laying plates, a dark box is arranged at the left end of the box, the right end of the box is transparent, thepartition plate frame is erected in the box, the partition plates are movably arranged on the partition plate frame, the partition plates are bilaterally swung front and back relative to the partitionplate frame, the partition plates and the partition plate frame can be relatively static, the egg laying plates are arranged on the partition plates and coated with the intermediate host eggs. According to the device, after the intermediate host eggs are placed, the trichogramma lays eggs on the egg laying plates, the egg laying plates can be obliquely arranged according to habits of the trichogramma, so that the trichogramma moves towards high positions, strong and weak illumination is arranged, so that trichogramma is driven to move towards one side of the strong illumination, and the trichogramma is driven to move.

Description

technical field [0001] The invention relates to the technical field of Trichogramma breeding, in particular to a Trichogramma egg collection device. Background technique [0002] Trichogramma is a natural enemy insect, which can be used for biological control of various agricultural pests. In order to breed Trichogramma in large quantities in production, the eggs of intermediate hosts (such as wheat moths) are usually used for factory multiplication. In the prior art, the intermediate host egg is usually painted on the surface of the egg-laying plate, and then the Trichogramma is placed on the egg-laying plate to impel the Trichogramma to lay eggs on the intermediate host egg. Due to the biological learning factors of Trichogramma, Trichogrammas tend to gather at the edge of the spawning plate, resulting in most of the intermediate host eggs on the spawning plate without Trichogramma parasitism, and the parasitism rate is not up to standard, which leads to waste of resource...
