Emergence release device for Noctuidae pupae in natural environment

Abstract

The invention discloses an emergence release device for Noctuidae pupae in the natural environment. The device comprises an inner cage and an outer cage, wherein the inner cage is installed at the upper part of the outer cage; the inner cage comprises a first frame which is provided with a first water chamber, a pupa chamber and a second water chamber from top to bottom sequentially; an opening Iis arranged on one side surface of the first water chamber, the pupa chamber and the second water chamber; and the top surface, the bottom surface and the other side surface are surrounded by gauze toform a space for placing articles; a partition plate is arranged in the pupa chamber, and divides the pupa chamber into a left pupa chamber and a right pupa chamber based on the opening I of the pupachamber as a partition face; and two observation doors capable of being opened and closed are arranged at the opening I of the pupa chamber, and correspond to the opening I of the left pupa chamber and the right pupa chamber respectively. Two structures, namely, an inner cage and an outer cage, are designed, the inner cage is arranged at the upper part of the outer cage, and the pupa chamber is completely surrounded by the gauze and is far away from the ground, climbing difficulty is increased for ants, and the risk that the pupae are eaten can be reduced.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a release device for Noctuidae pupae emergence used in natural environment. Background technique [0002] Noctuidae is the largest family of Lepidoptera, with more than 25,000 known species. Many species of this family are important agricultural and forestry pests, such as Spodoptera litura, Spodoptera litura, Spodoptera litura, Armyworm, Spodoptera moth, silver print moth, large borer, tea yellow poisonous moth. Noctuidae are holometabolous insects, with four stages of eggs, larvae, pupae and adults. Adults are typical nocturnal moths with strong phototaxis and sugartaxis. The forewings are dark and protective, and many species have migratory habits. , such as armyworms, cutworms, cotton bollworms, and armyworms, can migrate over long distances. Most of the larvae feed on the leaves and are often polyphagous. A few larvae eat stems and live in seclusion. Generally, matur...

Problems solved by technology

However, this device uses a control system, which is expensive and has no sunshade design, so the sun protection effect is not good; since pupae are one of the foods that ants like, they will attract ants after one to two hours in the natural environment. The feathering drawer is very close to the rollers on the ground. Even putting glue on the rollers is not conducive to preventing ants from climbing, and the pupae will be quickly eaten by ants
