ABSTRACT

One of the primary insects of stored goods thatcauses significant losses globally is Sitophilusoryzae L. (Coleoptera: Curculionidae), a pest of stored grains. Utilizationof synthetic pesticides, which are effective but also dangerous for theenvironment and human health, and has caused stored product pests to acquireresistance and disrupt the balance of ecosystem. As a result, creation of novelnatural insect-control methods utilizing plants products in form of plantessential oils in a binary combination to control S. oryzae as a substitute to chemical. The Preference index (PI)was observed by binary combination of Aeglemarmelos and Mentha arvensis are -0.95at 0.40% concentration (χ2 value=3.582) (P<0.05) with 95.35 per centrepellency. In A. marmelos and M. arvensis binary combination ofessential oils it also showed, minimum LC₅₀ value of 10.296 µl/cm3with maximum toxicity against adults at 48 hrs (F=28.358) (P<0.001),respectively comparison to other essential oils combinations. With thesub-lethal concentration 60% of 48 hrs. LC₅₀ value, the binarycombination of essential oils showed an antifeedant effect, reaching 85.69% forS. oryzae. In accordance with thepresent investigation, insecticides derived from plants can be employed as asubstitute for chemical pesticides in formulations, that measure theirinsecticidal effectiveness against S.oryzae as fumigants in the binary combinations.
