Method of rearing single-head diamondback moth indoors

Abstract

The invention belongs to the technical field of Lepidoptera moth rearing, aims to solve the problems that the existing feeding devices for feeding the diamondback moths affect the growth of larvae, the diamondback moths are difficult to observe in close range, which causes the adult diamondback moths to escape and affect the adult life of diamondback moths, and the existing feeding devices do not benefit the operation and experiment and the like, and provides a method of rearing single-head diamondback moths indoors. Fresh cabbage leaves are plugged in a feeding device to feed the single head diamondback moths, the feeding device comprises a cylinder-shape transparent feeding tube with both ends open, one end of the feeding tube is provided with a cabbage leaf growth block, the other end is provided with a sponge seal layer; a nutrition layer is arranged inside the cabbage leaf growth block, the top center of the cabbage leaf growth block is provided with a socket, and cabbage leaves are plugged in the socket. The cabbage leaves are kept in good freshness and tenderness and in good growth conditions by the plant nutrient solution. The adult life is extended through the rearing with fluctuating temperatures, and pupal weight is increased; the mortality rate of eggs, larva and pupa is reduced. Errors are reduced, the growth conditions of diamondback moths are easy to observe and record; the durability and operability are enhanced; and repeated use is possible. The device is low in manufacturing cost, secure, convenient and fast.

Description

technical field [0001] The invention belongs to the technical field of lepidopteran diamondback moth breeding, and in particular relates to an indoor breeding method for a single diamondback moth. Background technique [0002] Plutella xylostella, belonging to Lepidoptera, Plutellaidae, is distributed in cruciferous vegetable producing areas all over the country. It mainly damages cruciferous plants such as cabbage, purple cabbage, broccoli, stalks, mustard greens, cauliflower, cabbage, rapeseed, and radish. . Observing and mastering the development, survival, lifespan and reproduction of single-headed diamondback moth is an important basis for revealing the core life activities of diamondback moth in different ecological environments, and it is also the key to elucidating the environmental response mechanism of diamondback moth. To this end, it is necessary to create a test device and method of use that is relatively independent (free from interference by natural enemies, ...

AI Technical Summary

Problems solved by technology

[0007] The present invention solves the problem that the existing Plutella xylostella larvae feeding device cannot meet the total food intake of the larval growth stage of Plutella xylostella, the larvae have a small moving space, affects the growth of the larvae, and it is difficult to observe quickly at a close distance, and solves the problem of frequent replacement of leaves in the existing Plutella xylostella xylostella adult feeding device , cotton thread, and plastic wrap will cause the adults of diamondback moth to escape, and the difference in temperature and humidity between the inside and outside of the plastic bucket will affect the life of adults of diamondback moth, and the overall volume of the device is large, which is not conducive to operation and experiments. A kind of indoor rearing of single-headed diamondback moth is provided. method
