The khapra beetle is categorized as notorious species, an extended standing species around the world
and at the same time it is perceived among the world’s 100 most essential intrusive species. Thiamethoxam
and imidacloprid are Neonicotinoids with a minute toxicity and they have no teratogenic effects on grains,
therefore both are used as cereals protectant against stored grain pests world widely. The recent study was
planned to evaluate the efficacy of thiamethoxam and imidacloprid for the control of Trogoderma granarium
under laboratory conditions. The insecticides were tested at four different concentrations (0.25, 0.5, 1
and 2ppm). Mortality of insects was documented after 24, 48 and 72 hours. Abbot’s formula was used to
determine the corrected mortality. At 2ppm concentration thiamethoxam and imidacloprid provided 87.57%
and 78.59% mean mortality of khapra larvae on treated filter paper after 72 hours respectively. On treated
wheat, thiamethoxam provided 82.61% while imidacloprid gave 78.18% mean mortality of khapra larvae at
2ppm after 72 hours. Mortality was dose and exposure dependent. Results demonstrated that thiamethoxam
was more lethal as compared to imidacloprid for concern insects.
