A kind of indoor raising method and device of green-winged silkworm

Abstract

The invention relates to an insect rearing method and device, in particular to a diaphania angustalis indoor rearing method and device. The method comprises the steps of larva, pupa and imago rearing,egg collecting and incubation. Particularly, preliminary hatching larvae of diaphania angustalis are reared in a larva rearing device, glycine leaves are adopted as food, the larvae are reared to prepupa, and the prepupa is placed into a pupating device till pupating is performed; male and female pupae are recognized and then placed into emergence boxes separately, after emergence, the pupae areplaced into an imago rearing device in pair for mating and egg laying; eggs in the imago rearing device are collected and placed into a clean circular plastic culture dish with the bottom paved with moisture filter paper, small and tender glycine leaves are laid, the culture dish is placed into an artificial weather box, attention needs to be paid to moisturizing everyday till incubation is achieved; after larva incubation, the larvae are subjected to the steps circularly to perform subculture rearing. The influences of biological and non-biological factors on diaphania angustalis population survival and propagation are researched, and the insect source with the consistent insect state development progress is supplied.

Description

technical field [0001] The invention relates to an insect feeding method and a feeding device thereof, in particular to an indoor feeding method and device of the green silk borer. Background technique [0002] Diaphania angustalis Snellen (Lepidoptera: Pyralidae) is the main foliar pest of sugar tree Alastonia scalaris L. The degree of its harm is increasing year by year, which has aroused people's attention. The larva spins silk and rolls the leaves vertically to form a bud, and eats the mesophyll inside to cause damage. It has strong concealment and large food intake. In severe cases, the damage rate of plants reaches 90%-95%; the damage rate of young leaves reaches 85%; Withered and yellow, causing fallen leaves, resulting in bare branches and bare poles, seriously reducing its use value, medicinal value, and ornamental value, and affecting the growth of sugar gum and the development of biopharmaceutical industry. Although the green-winged silk borer is widely distribu...
