The control of this insectis still poor and involves the use of conventional insecticides. There is an increasing demand in thesearch for new active substances and products for pest control towards reduction of adverse e ectson human health and the environment. The protection of grains with alternative products, such asessential oils, is a possible alternative to meet the needs described above. Therefore, this investigationevaluated the applications of basil, Ocimum basilicum, and citronella, Cymbopogon winterianus, essentialoils for A. obtectus control. These essential oils significantly reduced the bean weight losses and thenumber of beans damaged by A. obtectus at higher doses than 60 or 120 L/sample. The number ofholes per bean did not di er between the doses of basil essential oil, not even at the dose of 60 L,while it was higher at 120 L, probably due to a lower capacity of movement of the insects treatedwith this dose and/or the oil’s direct or indirect e ects on the insects. Basil and citronella oils exhibitedsimilar patterns of insecticidal activity over the insect, both directly in adult insects or indirectlyover bean seeds. These essential oils a ected the development of A. obtectus since the greatest dosesapplied on beans decreased the emergence of the bean weevil. The results prove the insecticidalcapacity of the tested essential oils and hence their potential as active substances against A. obtectus inenvironmentally low risk pest control strategies. Supplementary trials should be conducted underreal storage conditions.
