Potential of selected plant essential oils in management of Sitophilus oryzae (L.) and Rhiyzopertha dominica (F.) on wheat grains

Abstract Background Two plant essential oils, basil ( Ocimum basilicum L.) and petitgrain mandarin Citrus reticulate L.), one pyrethroid chemical insecticide, lambda-cyhalothrin, were evaluated against two of the most important stored product insect pests, Sitophilus oryzae Rhyzopertha dominica , on wheat grains under laboratory conditions using mixing with feeding method. The effect tested materials was studied F 1 progeny insects. Chemical components oils side effects protein content percentage, total carbohydrates grain germination investigated. Results obtained showed that had a good insecticidal Petitgrain oil premier. reduced progeny. In addition, progressive periods after storage (0–180 days) significantly (%) compared to control. Nearly, there no significant differences between treatments (LC 50 LC 95 ) (petitgrain) parameters. Germination percentages from 0 180 days post-storage slight control for oils. Lambda-cyhalothrin germination, especially 60 days. analysis demonstrated main linalool, eugenol, methyl chavicol cani, while dimethyl panthenalate, α-terpinene, β-cinem citral accounting 71.1 95% respectively. Conclusions results proved an obvious role in suppressing activity insects can be used integrated pest management program. as green pesticides effective alternatives pesticides.
