Abstract

Studies involving microstructure, ecobehavioural, physiological, cytogenetic and biochemical aspects were shown to be useful in revealing the true nature of species and genera. Considerable work has been carried out on the biosystematics of parasitic insects, which included a search for new characteristics both in the adult and immature stages, studies on the life cycle, longevity and fecundity, examination of animal products as well as crossing experiments using individuals collected from different hosts or habitats
