Intrinsic rates of increase and interspecific relationships between Cotesia orientalis, Cotesia diurnii and Diadegma tarichoptilus (Hymenoptera: Ichneumonidae), the larval parasitoids of Exelastis atomosa

Intrinsic rates of increase and interspecific relationships between Cotesia orientalis, Cotesia diurnii and Diadegma tarichoptilus (Hymenoptera: Ichneumonidae), the larval parasitoids of Exelastis atomosa

The intrinsic rates of increase of the braconids Cotesia orientalis and C. diurnii and the ichneumonid Diadegma trichoptilus, parasitoids of Exelastis atomosa, were determined in the laboratory at 24 degrees C and 55-60% RH. The intrinsic rates of increase were 0.188, 0.158 and 0.149, resp., and the populations multiplied by 41.93, 25.99 and 25.63 times in mean generation times of 19.87, 20.61 and 21.77 days.
