Introduction
Amitus hesperidum Silvestri is one of the most effective parasites of the citrus blackfly, Aleurocanthus woglumi Ashby. This parasite was described by Silvestri in 1 927 from Aleurocanthus citriperdus in Hong Kong and Singapore ( Silvestri 1927). It was collected in India and introduced into Mexico for controlling citrus blackfly (Smith et al. 1964). Because of the success in Mexico, it was imported into Texas ( Summy et al. 1983) and Florida (Hart et al. 1978) to suppress the population of citrus blackfly in these states.
