Dastarcus helophoroides imago feeding box and egg collecting method

Abstract

The invention belongs to the technical field of biological control, and discloses a dastarcus helophoroides imago feeding box and an egg collecting method. The feeding box comprises a box body with the top of an opening structure, a net plate horizontally arranged in the box body and close to the bottom of the box body, a tray arranged in the box body, and a box cover; an opening in the bottom of the box cover is matched with an opening in the top of the box body; a plurality of grid holes are distributed in the net plate; a feed disc, a moisturizing centrifugal tube and an egg collecting card are arranged on the net plate; and the tray is located at the bottom of the box body and is located below the net plate. The feeding box is simple in structure and large in living space, excrement is convenient to clean, eggs are convenient to collect, the survival rate of dastarcus helophoroides imagoes and the working efficiency of follow-up egg card collection and release are improved, large-scale application and popularization of the dastarcus helophoroides imago feeding box are facilitated, and therefore the yield of dastarcus helophoroides is improved.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to a breeding box and egg collection method for velvet parasite adults. Background technique [0002] Flower velvet beetle (Dastarcus helophoroides Fairmaire, also known as flower velvet hard armor, flower velvet hole armor, carpenter hornet and constricted wing armor, etc.) belongs to the order Coleoptera (Coleoptera, bothrideridae), and is a long-tailed long-tailed beetle. Monochamus alternatus Hope, Anoplophora glabripennis, A. chinensis, Massicus raddei Blessig, etc. are one of the effective parasitic natural enemies of long beetle borer pests, and they are the dominant natural enemy insects currently used for biological control. [0003] At present, the release of the egg card of the velvet beetle to control the pine beetle, star beetle, and pink-necked beetle has achieved good control effects, and the market demand for the egg card of the velvet beetle is also gradu...

Problems solved by technology

[0004] Conventional velvet beetle adults are mainly raised in plastic fresh-keeping boxes. The bottom of the box is lined with plastic gauze, and feed, water and a certain number of velvet beetle adults are placed in the box. This method makes the velvet beetle Adults feed and excrete in the same area, and the air permeability of the plastic box is poor, which makes the feed easy to breed caseosa mites, and the adult velvet beetle is easy to be infected with bacteria and die, and the survival rate of adults is reduced
