Linking life table and predation rate for biological control: A comparative study of Eocanthecona furcellata (Hemiptera: Pentatomidae) fed on Spodoptera litura (Lepidoptera: Noctuidae) and Plutella xylostella (Lepidoptera: Plutellidae)
Journal of Economic Entomology 109 (1), 13-24
Abstract: To better understand the predator–prey relationship and to compare predation rates, we studied the life table and predation rate of the predator Eocanthecona furcellata Wolff (Hemiptera: Pentatomidae) when reared on two major crucifer pests, Spodoptera litura (F.) (Lepidoptera: Noctuidae) and Plutella xylostella L. (Lepidoptera: Plutellidae). The net reproductive rate, intrinsic rate of increase, finite rate, and net predation rates of E. furcellata reared on P. xylostella were 292.4 offspring, 0.1389 d-1, 1.1490 d-1, and 644.1 third instars of P. xylostella, respectively. These values are significantly higher than those reared on S. litura, i.e., 272.3 offspring, 0.1220 d-1, 1.1298 d-1, and 863.1 third instars of S. litura. To evaluate the predation potential of E. furcellata fed on P. xylostella and S. litura, we combined both the growth rate and predation rate to calculate the finite predation rate (omega); our results showed that E. furcellata is an effective predator of both S. litura (omega = 1.6029) and P. xylostella (omega = 1.4277).
