Abstract:
Reproduction and longevity of Podisus restralis (Stil) (Heteroptera:Pentatomidae) females, fed at different intervals were studied in the 'Nucleo de Biotecnologia Aplicada A Agropecuaria' (BIOAGRO), of the'Universidade Federal de Vigosa' (UFV), in Viqosa, Minas Gerais, Brazil, at 25 t 2 deg. C, 70 t 1096 R.H. and photophase of 12 hours. Females of P. rostralis were fed with Tenebrio molitor L. (Coleoptera: Tenebrionidae) larva, during 24 hours, every one, two, four, eight and16 days. An inverse linear effect was found between oviposition period, egg batches/female, total number and number of eggs per day with feeding interval. Daily fed females laid more eggs (199.6) while those fed every 16 days showed lowest number of eggs (45.3). Longevity ofP. rostralis was similar in all feeding intervals. Egg oviposition rate was reduced but females of this predator maintained its longevitywhich give then higher chances to maintain themselves in the ecosystem until occurs better conditions of preys.
