Abstract

The bean weevil, Acanthoscelides obtectus (Say, 1831), is a problem for producers and storage of legumes. It is estimated to cause as much as 20% loss of production. It also reduces the quality of harvest and affects viability of seeds for sowing. Ethanol extracts from eight plants were evaluated: saltmarsh leaf, Baccharis glutinosa Pers.; eucalyptus, Eucalyptus globulus Labill; creosote bush, Larrea tridentata (Sessé & Moc. ex DC.) Cov.; tree tobacco, Nicotiana glauca Graham; cacachila, Karwinskia humboldtiana (Shult.) Zucc.; chinaberry seed, Melia azedarach L.; castor, Ricinus communis L.; and copalquin bark, Hintonia latiflora Bullock, at doses of 5, 10, 15, and 20% w/v. Corrected mortality and pest emergence, repellency index, percentage of damaged seed, and loss of germination capacity were evaluated. Results indicated that N. glauca and K. humboldtiana (10% w/v) were the best treatments with 0% damaged seed, no emergence of the F1 generation of the pest, and maintained ability to germinate. Extracts of the two plants might be an alternative to manage A. obtectus in stored beans.
