Size of Interacting Resource-Host-Parasitoid Populations Influences Mass Rearing of Cotesia vestalis

The importance of Cotesia vestalis (Haliday) has been well documented as one of the most significant biocontrol agents for the diamondback moth, Plutella xylostella (L.). The aim of the present study was to optimize the procedure of mass rearing of C. vestalis. The effects of space and plant-herbivore-parasitoid biomass on the quality of produced wasps were investigated. In particular, the effects of food and space resources of P. xylostella and...
