| The functional and numerical responses, reproductive characteristics, and viability of Campoletis flavicincta (Hymenoptera: Ichneumonidae) as well as the mortality after parasitism of the host Spodoptera frugiperda (Lepidoptera: Noctuidae) were analyzed in the laboratory. Campoletis flavicincta pairs were maintained until female death with 10, 20, 30, 40, or 50 caterpillars day-1 of the host S. frugiperda. A type III functional response curve was fitted to the average number of caterpillars supplied per day during the female wasp lifespan, as the explanatory variable. The handling time was 0.5940 ± 0.0875h, and the instantaneous search 0.0047 ± 0.0020 h-1. The functional response for each of the first five days of the host was a type III. The longevity at... |
