Abstract: Continues use of synthetic insecticides has resulted in resistance towards insecticides. Therefore, present study was conducted to evaluate the biocontrol potential of three essential oil fumigation viz., Zea mays, Zingiber officinale, and Allium sativum against flour beetle Tribolium confusum. For this purpose, fourth larval instars and adults were treated with a different concentration of selected essential oils. Results of present study revealed that after 24 and 48 hours, fourth larval instars were more susceptible to the used plants oil fumigation as compared to the adults. Among the tested oils, fumigation by ginger oil showed highest mortality rate on the fourth larval instars and adults after 24 and 48 hours and it was followed by the fumigation by garlic essential oil. Therefore, from these results, it can be conclude that essential oils fumigation could be use for the biocontrol of flour beetle Tribolium confusum.
