  • Reproductive behavior of the red-striped golden stink-bug, Poecilocoris lewisi Distant, was investigated in a room at 25${\pm}$1$^{\circ}C$, 60${\pm}$5% R.H. and the 16L:8D photo regimen. Mating of adults started on the 9th day after emergence, peaked 84.5% on the 21st day. Mating behavior of this insect was observed as follows : approach, antennal contact, mount, abdominal approach and copulation (end-to-end position). Males were quite active and produced by rubbing their body with the cages while searching for the females. However, the females responded passively during mating. Studios were further carried to see the response of virgin pairs under controlled conditions. It was observed that 69% of pairs succeeded in mating within one hour after the lights were switched on. Females remained unreceptive for 7 days of first mating, however, males were very much positive subject to the availability of virgin females. Although the remating frequency of female was positively correlated with fertility, but a male showed lower fertility as its frequency increased.
