Abstract

The biological properties of Trichogramma evanescens that may influence lifetime productivity and its performance as a biocontrol agent were quantified. The mode of reproduction was re-evaluated and the rate of egg and sperm maturation was determined in the presence and absence of food. T. evanescens undergoes a sex-related parthenogenetic development. The female wasp requires about five hour pre-oviposition period. The average number of mature ovarian eggs per female per day from starved wasps was 17±4 eggs and wasps lived for a maximum of three days. With food, the average number of mature ovarian eggs per female per day was 28±4 eggs and wasps lived for a maximum of nine days.
