Factors determining the functional response of the parasitoid Venturia canescens
1989
Trudeau, D. | Gordon, D.M.
A series of experiments were undertaken to determine the factors responsible for the maximum number of hosts attacked by the parasitoid Venturia canescens (Gravenhorst) (Hymenoptera: Ichneumonidae) in the course of functional response experiments. Egg limitation is not a constraint on the maximum number of parasitoid progeny produced per day. Rather, the constraints arise from the requirement that eggs must be moved from the ovarioles to the oviducts and the rate at which this occurs, together with the existence of a positive relationship between the rate of parasitoid searching behaviour and the number of eggs in the oviducts.
