Alternative treatments in bean seeds for repelling Acanthoscelides obtectus (SAY)

Abstract: The objectives of this study were to evaluate treatments with alternative products for repelling bean weevils, and to assess their influence on the physiological quality of Phaseolus vulgaris seeds. The experiment was carried out in a completely randomized design, with four replications, in a two-factorial scheme (10x4). It comprised 10 treatments: Piper nigrum, diatomaceous earth and kaolin (4 g/kg of seed); Cinnamomum zeylanicum, Citrus sinensis and Eucalyptus sp. (1% of the seed weight); Azadirachta indica … Show more

“…Previous studies of EO effects in A. obtectus have involved EOs isolated from plants belonging to families of Amaranthaceae [58], Asteraceae [59], Cupressaceae [60], Lamiaceae [61][62][63], Lauraceae [64], Meliaceae [65], Myrtaceae [60,62,64,66], Piperaceae [65], Poaceae [67], Rutaceae [68]. In the present study we examined how thyme EO (Thymus vulgaris L., Lamiaceae, thymol chemotype) applied by contact affected A. obtectus mortality, F1 progeny production and choice of seeds for oviposition.…”

“…Without any treatment, the A. obtectus populations grow exponentially and could completely destroy the stored beans [17]. The most common method to control weevil in beans for human consumption is by phosphine or pyrethroids [18]. As regards the seeds for sowing, the complete control of bruchids can be achieved by an insecticide coating of the stored seeds.…”

“…Recently, as a result of the increase in ecological awareness, biological control methods have begun to be used which can be an alternative to chemical control (Oliveira et al 2018). Success in biological control depends on the determination of control strategies and timing.…”
