An experiment was conducted during Kharif season of 2016, to evaluate the field efficacy of certain insecticides against rice gundhi bug [Leptocorisa acuta (Thonberg)] under agro-climatic condition of Allahabad, at Central Research Farm, SHUATS, Naini, Allahabad. Three applications of seven insecticides viz Imidacloprid 17.8% SL, Trizophos 25% SP, Monocrotophos 36% SL, Thiamethoxam 25% WG, Acephate 75% SP, Carbaryl 50% SP, Malathion 50% EC were evaluated against Rice Gundhi bug, Leptocorisa acuta. Results were revealed that all the treatments were effective significantly to suppress population of gundhi bug as compared with control (3.51 bug/hill). And the treatment Imidacloprid was recorded lowest population of gundhi with (0.91 bug/hill) and found to be superior among all other treatments. This was followed by Thimethoxam (1.22 bug/hill) < Triazophos (1.44 bug/hill) < Monocrotophos (1.77 bug/hill) < Acephate (2.06 bug/hill) < Carbaryl (2.57 bug/hill) < Malathion (2.84 bug/hill) respectively.
