Abstract:

A laboratory bioassay was carried out to determine LC50 and relative toxicity of three plant oils along with check chlorpyriphos 20EC and control against termite, Odontotermes obesus. The data on mortality of Odontotermes obesus revealed that among the plant oils tested neem oil showed the lowest LC50 value (0.241) followed by karanj oil (0.636) and jatropha oil (2.130) after 72 hours exposure period. Considering the relative toxicity of chlorpyriphos as unit value the comparison of relative toxicity revealed that neem oil, karanj oil and jatropha oil were 0.066, 0.025, 0.008 times less toxic than chlorpyriphos after 72 hours exposure period respectively. The order of relative toxicity was found in the following manner; neem oil >karanj oil >jatropha oil.


Keywords: Odontotermes obesus, LC50, relative toxicity, plant oils and chlorpyriphos
