Breeding method for feeding spodoptera frugiperda larvae with teosinte

The invention relates to the technical field of insect feeding, in particular to a feeding method for feeding spodoptera frugiperda larvae with teosinte. Comprising the steps that larvae from the first age to the second age are placed in culture containers, one larva is placed in each culture container, 1-4 teosinte leaf sections are placed in the culture containers every day, gaps between upper covers and lower bottoms of the culture containers are sealed, and ventilation openings are reserved; when the peste des petits grow to 3-4 years old, 2-4 peste des petits leaf sections are put into the culture container every day, and a gap between an upper cover and a lower bottom of the culture container is reserved; when the larvae grow to 5-6 years old, putting 2-5 teosinte leaf sections into the culture container every day, and reserving a gap between the upper cover and the lower bottom of the culture container until the larvae pupate. According to the method, the larvae of the spodoptera frugiperda are bred in
