Safety of four combination products of insecticides and two single Compound insecticides to adults of brown mirid bug Tyttus parviceps, a predator of rice planthoppers was assessed under greenhouse conditions. Two combination products viz chlorpyriphos (50%.) + cypermethrin (5%,) (at 344 ppm.) and acephate (45%) + cypermethrin (5%) (at 500 ppm) were relatively safer than other two combination products, but less safe than acephate (750 ppm) or monocrotophos (500 ppm). In general, all the products were safer to nymphs of T. parviceps than to adults.
