Present study was analyzed to determine the toxicological effects of Urgineamaritime at different concentrations (0.1, 1 and 10%) against larvae and adults of Triboliumcastaneum. In the present study it was observed that by tropical application, leaf extract shows highest toxicity to larvae as compared to adults. LC50 value and LC90 value was found to be 27.8g/L and 55.1g/L respectively in probit analysis of leaf extract for the larvae. However the bulb extract was found to be more toxic, LC50 and LC90 values were much lesser with 16.6 and 34.4g/L respectively. The present study also determined the in vivo toxicity of leaf as well as bulb extracts on larvae and the LC50 value was found to be 92 and 19.3g/L respectively. Similarly in residual film toxicity, LC50 and LC90 were found to be 87.9 and 495.4g/L, respectively. However no mortality was observed in the present study in the control experiment.
