Lima Multidisciplinaria (Ciencias Naturales y Exactas) cowpea tridecanone Pilocarpus microphyllus Callosobruchus maculatus The effect of 2-tridecanone vapor on the cowpea weevil (Callosobruchus maculatus) development was determined.Seeds of cowpea were infested with adults and exposed to different doses of 2-tridecanone isolated from Pilocarpusmicrophyllus Stapf ex Holm, a plant species native from northeastern Brazil. The pure monoterpene was evaluated bothundiluted as well as in the dilutions 1:10, 1:100 and 1:1,000 (v/v). The following parameters of the cowpea weevillife cycle were analyzed in response to decreasing doses of 2-tridecanone: number of eggs laid, percentage of egghatching on seeds, percentage of adult emergence, adult weight at emergence, mean developmental time and numberof adults emerged. Vapor of 2-tridecanone caused a significant (P < 0.05) reduction in the number of eggs laid, in thepercentage of eggs hatched and in the number of emerged adults in infested seeds. The fumigant insecticidal effect of2-tridecanone was mainly due to its ovicidal activity. 2007 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32779105 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.1 Vol.79 |
