Abstract
Rice earhead bug, Leptocorisa acuta Thunberg (Hemiptera: Alydidae) is found in almost all the countries where rice crop is grown. It, however, becomes more prevalent in rainfed wetland or upland rice. In Tripura, rice earhead bug (REB) is one of the major pests of rice crop leading to considerable field losses. Experiments were conducted in the field to evaluate the efficacy of some insecticides against REB, L. acuta. The results in field evaluation showed that all the insecticides are having significantly reduced pest population. The mortality percentage of L. acuta caused by different insecticides ranged from 74.01 to 97.03%. Among all the treatments tested, Quinolphos 25 EC gave the highest mortality(97.03%) as compared to untreated control (5.48%).
