A kind of insect cage and breeding method for large-scale breeding of predatory natural enemy stinkbug

Abstract

The invention discloses an insect rearing cage for large-scale rearing of a predatory natural enemy arma chinensis fallou and a rearing method for arma chinensis fallou. The insect rearing cage comprises an insect rearing cage body, strainers and perching rods, wherein the insect rearing cage body is formed by assembling a top cover and a bottom plate, which can be disassembled; a plurality of strainer carrying holes for inserting the strainers are uniformly formed in each surface of the cage body and the top cover; a plurality of perching rod carrying holes for inserting the perching rods are also uniformly formed in the top cover. The rearing method comprises the following steps of placing arma chinensis fallou adults in the insect rearing cage for rearing, directly disassembling the strainers and the perching rods, on which eggs are laid, from the insect rearing cage, incubating and developing the eggs on the strainers and the perching rods into second-instar larvae, placing the second-instar larvae in the insect rearing cage, and continuing rearing the second-instar larvae into adults. According to the insect rearing cage and the rearing method, arma chinensis fallou can be reared on a large scale, the egg laying rate, the rearing space and the rearing cost are greatly improved, and the reared adults can be used for a plurality of purposes such as propagation or biological characteristic researches or field release for preventing and controlling target pests.

Description

technical field [0001] The invention relates to the technical field of insect breeding, in particular to an insect cage used for large-scale breeding of predatory natural enemy gnats and a method for raising gnats. Background technique [0002] The stinkbug is a natural enemy insect with a wide range of predation. It can prey on more than 40 common agricultural and forestry pests such as pine caterpillars, inchworms, leaf beetles, sting moths, scale insects, and cabbage caterpillars. It has a significant effect in controlling the number of pest populations. The use of gnat bugs in biological control can greatly reduce the use of pesticides in the field and in the greenhouse, protect the ecological environment, and ensure food and food safety. [0003] The traditional breeding tool for stinkbugs is a cuboid bracket connected by wooden or iron materials, the four walls and the bottom are made of gauze, and the front is made into a cuff or a small door that can be opened and cl...

Problems solved by technology

However, the biggest disadvantage of this kind of insect cage is that the gnats lay their eggs on the walls or brackets of the cage. When collecting eggs, the insect collection port can only be opened and scraped off the walls or brackets with a small blade.

There will be 3 kinds of adverse consequences in this way, one is easy to cause damage to the eggs, the other is laborious and laborious, many adults escape during the operation, and the third is that many eggs produced in the cracks cannot be taken out, resulting in losses. The density is 0.3 heads / cm 2 , so most of the space inside the traditional insect cage cannot be used, resulting in increased feeding costs, and cannot be raised on a large scale
