Abstract

Biological Data of Podisus nigrispinus (Dallas) Fed Dione juno juno (Cramer) Larvae ABSTRACT-Survival and life cycle of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) fed Dione juno juno (Cramer) (Lepidoptera: Heliconiidae) larvae were studied at 25 ± 2°C, 65 ± 10% RH and 12 h D:L. Duration of egg stage and of 1st, 2nd, 3rd, 4th and 5th stadia was 4.0; 4.0; 4.9; 4.7; 4.8 and 5.8 days, respectively. Survival from 1st instar to adult stage was 67%. The predator took 28 days and the prey 33 days to complete the life cycle.

Comparison of Eggs, Larvae, and Pupae ofPlutella xylostella(Lepidoptera: Plutellidae) as Prey forPodisus nigrispinus(Hemiptera: Pentatomidae)

“…• Number of eggs produced per female and the survival data ofthe predators, we prepared were used to calculate fertility life tables for P. nigrispinus fed P. xylostella larvae and pupae {Table 6). The data obtained for the parameters used in the fertility life table were as follows for the larvae and pupae fed predators, respectively: R«, 216.1 and 267.2; T, 33.4 and 32.1 d; r"" Discussion P. nigrispinus development was more rapid in our study than that reported for stink bugs fed Dionejuno jinw {Cramer) (Lepidoptera: Nymphalidae), which were 4.9, 4.7, 4.8, and 5.8 d for the second to fifth instars, respectively (Moreira et al 1998). Rates sim- ilar to those reported here have been obtained with D. saccharalis as prey, with a nymph development period of 18.2 d ( Vacari et al 2007).…”

“…Rates sim- ilar to those reported here have been obtained with D. saccharalis as prey, with a nymph development period of 18.2 d ( Vacari et al 2007). In similar studies, survival was only 67% for nymphs fed D. juno juno larvae (Moreira et al 1998) and 89% for those fed D. saccharalis (Vacari et al 2007). The specie P. distinctus showed 18.7 d to nymphal period using Bombyx mori (L.) (Lepidoptera: Botnbycidae) as prey (Lacerdaet al 2004).…”

A dieta alimentar da presa Tenebrio molitor (Coleoptera: Tenebrionidae) pode afetar o desenvolvimento do predador Podisus nigrispinus (Heteroptera: Pentatomidae)?

“…O percevejo predador P. nigrispinus geralmente é alimentado com larvas ou pupas de Tenebrio molitor Linnaeus, 1758 (Coleoptera: Tenebrionidae) devido ao baixo custo e fácil manutenção em laboratório (Vivan et al ., 2002). Estas podem afetar o desempenho reprodutivo deste predador, podendo ser de forma semelhante (Lemos et al, 2003) ou superior a presas naturais, como larvas de Lepidoptera (Moreira et al, 1998;Espindula et al, 2010) ou presas alternativas, como o bicho da seda (Zanuncio et al, 1994) ou larvas de mosca doméstica (Jusselino Filho et al, 2001). Esta última, no entanto, pode ter custo mais baixo (De Bortoli et al, 2011).…”

Morphology of female reproductive tract of the predator Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) fed on different diets

“…Studies on biology (Medeiros et al, 1998, Moreira et al, 1998, ecology and nutrition (Saavedra et al 1996 have been developed but little is known about the reproductive tract, internal morphology and histology of P. nigrispinus. The female reproductive system of insects consists of a pair of ovaries in the abdomen above or lateral to the gut, and it is formed by functional units denominated ovarioles associated to tracheae and fat body (Engelmann 1970, Davey 1985, Nijhout 1994, Chapman 1998.…”
