Effects of granulated sugar on the longevity and fecundity of Orius strigicollis were examined under laboratory conditions. The 50% survival duration of adult female O. strigicollis fed with 3-5% glucose was 9-10 days and survival of those fed with solid granulated sugar was more than 25 days. The latter result was not different from that of females fed with Ephestia kuehniella eggs. The total number of eggs laid per female with a diet of both solid granulated sugar and yeast was twice as many as that with solid granulated sugar alone. Under weak starvation (fed 3 eggs of E. kuehniella per day), longevity of O. strigicollis females with solid granulated sugar was about five times as long as that of the control and fecundity was about three times greater. There were a few nymphs with mixed artificial diet (solid granulated sugar, trehalose, yeast and casein) that grew to adult stage and laid eggs.
