Continuous rearing of the aster leafhopper, Macrosteles fascifrons, on a chemically defined diet

A holidic diet for feeding the aster leafhopper, Macrosteles fascifrons, was formulated. The amino acids, B-vitamins, and sucrose are less concentrated than in aphid diets. Cholesterol, at 5 mg/ml, is required for the last ecdysis. Although leafhoppers reared on this diet have poorer survival and shorter life span than those reared on plants, they produce more progeny. Leafhoppers reared on this diet have completed the ninth generation and the culture is still thriving.
