Reproductive strategy of Podisus rostralis (Stal) (Heteroptera : Pentatomidae) females under different feeding
Biocontrol Science and Technology 8 (4), 583-588
Abstract: The reproduction and survival of Podisus rostralis was evaluated under different feeding intervals using Tenebrio molitor larvae as food and a continuous supply of bean slices. There was a linear relationship between the pre-oviposition period and the periods without feeding. Females fed at intervals of 1-4 days laid their first egg mass 8-10 days after emergence, while those fed every 8 and 16 days did so after 13.6 and 20 days respectively. The oviposition period, number of egg masses, total number of eggs, number of eggs/egg mass, total number of nymphs and rate of egg consumption/day showed negative linear correlations with the increase in feeding interval. The longevity of P. rostralis was not affected by feeding interval (P> 0.05). The present results suggest a type of trade-off, where longevity is maintained at the expense of reproduction. This behaviour or attribute of P. rostralis can contribute to its establishment and survival in an environment of fluctuating food supply.
