Abstract

The biology of the rice grain bug, Paraeucosmetus pallicornis (Dallas), was studied on string beans, Phaseolus vulgaris L. and rice, Oryza sativa L. under laboratory conditions at ambient temperature range of 28-30 deg C in clear bottles. P. pallicornis completed the biology on string beans and rice; however, significant differences were observed in the life history, fecundity and oviposition period of the insect. The insect passes through the egg stage and four nymphal instars before becoming an adult. The adult stage is longest, lasting for about twice the individual stages of post embryonic development. Full understanding of the biology of P. pallicornis led to the development of a mass rearing technique under laboratory conditions.
