Method for efficient chilo suppressalis breeding

Abstract

The invention provides a method for efficient zizania aquatica chilo suppressalis and rice chilo suppressalis breeding. The method includes that a first device and a second device are provided, wherein the second device comprises a colorless and transparent 500ml glass bottle; four layers of gauzes are paved at the bottom of the glass bottle, and a filter sheet is cushioned on the gauzes; three sections of fresh zizania aquatica are placed above the filter sheet in a triangle mode, and one layer of preservative film and one towel block are sequentially placed on the zizania aquatica; then, the opening of the glass bottle is covered with black cloth which is tightened through a rubber ring; or the second device comprises a colorless and transparent 500ml glass bottle; a wetted filter sheet is paved at the bottom of the glass bottle; rice seeds already sprouted are sown on the filter sheet, and when rice seedlings grow by 4-5cm, one layer of preservative film and one towel block are sequentially placed above the rice seedlings; after that, the opening of the glass bottle is covered with the black cloth which is tightened through the rubber ring. The chilo suppressalis can be gathered at one place for pupation, so that efficiency of pupa collection is improved, and death rate of the pupa is greatly reduced.

Description

Technical field [0001] The invention belongs to the technical field of insect breeding and is used for a new method for indoor continuous breeding of Chilo suppressalis to collect pupae. Background technique [0002] Chilo suppressalis Walker (Chilo suppressalis Walker) belongs to Lepidoptera Pyralidae, a completely metamorphic insect. The mouthparts of the larvae are chewing type, which is an important boring and omnivorous pest. It mainly feeds on many gramineous crops such as rice, water chestnut, corn, and sugarcane. Chilo suppressalis overwintering with mature larvae in rice straws, rice stumps, spring flowering plants, zizania remnants and weeds, and pupate in the following spring when the temperature and humidity are suitable. [0003] In recent years, due to the large-scale planting of host plants, the replacement of rice varieties, changes in farming systems, and climate change, the population of Chilo suppressalis has shown an upward trend in recent years, and its damage...

Problems solved by technology

[0006] However, the indoor artificial breeding of Chilo borer in the above prior art is cumbersome and complicated, and it is difficult to raise, which not only consumes a lot of time, but also host plants (such as wild rice stems, rice seedlings) are easy to rot and deteriorate or become moldy, causing the larvae to be easily malnourished and infected. Therefore, the mortality rate of larvae is high; coupled w
