Abstract

A method for culturing Spodoptera frugiperda in a laboratory in winter, comprising the following steps: S1, pairing of adults; S2, unified egg rearing; S3, hatching and feeding; S4, clearing feces of 1-3 instar larvae, and changing feed; S5, advanced age The larvae are reared separately; S6, prepare the environment for pupation; S7, concentrate the pupae, and pupate into adults. The present invention adopts different devices in each period, and adopts disposable plastic cups when mating adults and raising larvae. The narrow space of disposable plastic cups is conducive to adult mating, and young larvae are small and crawl fast, and feeding with cups can prevent larvae the escape of older larvae; adopting a grid rearing device for advanced larvae has not only avoided the mutual biting caused by competition, but also saves space, and can raise larvae of different ages at the same time; in the present invention, Spodoptera frugiperda is raised in the laboratory in winter, effectively Improve the survival rate, high breeding density, small footprint, increase production, easy operation, save time and labor.

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 ...
