Abstract

A method for in-lab breeding of Spodoptera frugiperda in winter comprises the steps of (S1) adult pairing, (S2) uniform egg cultivation, (S3) incubation and feeding, (S4) excrement cleaning and feed changing for first to third larvae, (S5) dividing and breeding of advanced-age larvae, (S6) preparation of a pupation environment, and (S7) centralized pupa breeding and worm formation by pupation. Different devices are used in different stages, disposable plastic cups are used during adult pairing and larva breeding, narrow space of the disposable plastic cups is beneficial for adult pairing, andescape of young-age larvae which are small in size and quick in creeping can be prevented through cup breeding; and a latticed breeding device is used for the advanced-age larva, so that mutual bitingcaused by competition can be avoided, space is saved, and the larvae of different ages can be bred at the same time. The method for in-lab breeding of Spodoptera frugiperda in winter effectively increases a survival rate, is high in breeding density and small in floor area, increases the yield, is convenient to operate and saves time and effort.

Description

technical field [0001] The invention relates to the field of biotechnology, and specifically belongs to a method for breeding Spodoptera frugiperda in a laboratory in winter. Background technique [0002] Spodoptera frugiperda is an important pest that invaded my country in 2019. It is extremely harmful to crops such as corn, rice, and wheat. As a migratory pest, it has been colonized in southern my country. The task of prevention and control is even more arduous. In order to effectively prevent and control the outbreak of fall armyworm, many universities and scientific research institutes have carried out all-round research on it. Since the annual occurrence area of ​​fall armyworm in my country is mainly south of the isotherm with an average daily temperature of 10°C in January areas, including the tropical and subtropical regions of Hainan, Guangdong, Guangxi, Yunnan and Fujian provinces. Therefore, the population must be cultured in the laboratory during winter research ...
