TI  - Insecticidal Efficacy and Repellency of Trans-Anethole Against Four Stored-Product Insect Pests
AB  - In this study, it was investigated that repellency andinsecticidal efficacy of trans-anethole of botanical origin onmajor stored product on pests species, namely Sitophilusgranarius (L.) (Coleoptera: Curculionidae), Sitophilusoryzae (L.) (Coleoptera: Curculionidae), Triboliumconfusum Jacquelin du Val (Coleoptera, Tenebrionidae) andTribolium castaneum (Herbst) (Coleoptera, Tenebrionidae).Repellency effect was evaluated by choice test in petridishes, while the mortality effect was examined by exposureto wheat treated at different concentrations, such as 1, 2, 3,4, and 8 µL trans anethole. In efficacy tests, after 72 hoursexposure, the highest adult mortality was found on T.castaneum with a 60% mortality, while other test speciesshowed no significant mortality. On the other hand,repellency tests revealed varying degree of repellencydepending on the application dose of trans-anethole. It wasdetermined that S. granarius belongs to repellent class III,while all of the other species fall under repellent class IV. F1progeny decreased as trans-anethole concentration increased,and in this context 8 µL of trans-anethole is proved to be theoptimal concentration causing maximum decrease inprogeny production. Among the insect species tested, T.confusum was found to be the most sensitive to transanethole with 100% decrease in F1 progeny production. Ourresults indicate that trans-anethole can be used as a potentialrepellent for the control of major stored grain pests.Additionally, trans-anethole, by its contact efficacy, might beconsidered as a grain protectant against S. granarius, S.oryzae, T. confusum and T. castaneum.
