Insect infestation on stored cowpea (Vigna unguiculata) is an economic obstacle to agriculture. In this context, a test in laboratorial scale was proposed aiming to investigate Ocimum gratissimum, O. basilicum, Cymbopogon nardus, C. citratus, Lippia alba, Mentha arvensis, Schinus terebinthifolius and Cordia verbenacea essential oils (EOs) fumigant potential on control of cowpea-weevil (Callosobruchus maculatus) life cycle. Thus, EOs were extracted and analyzed by GC/MS, furthermore, were used for evaluating mortality, oviposition and new adults emergence. As a result of EOs analyses linalool (32.8%) and eugenol (48.1%) in O. basilicum; eucalyptol (14.8%) and eugenol (74.5%) in O. gratissimum; menthyl acetate (10%) and menthol (73.3%) in M. arvensis; citronellal (50.3%) and nerol (10.8%) in C. nardus; citral (75.8 and 87.1%) in C. citratus and L. alba respectively; ?-santalene (35.8%) and ?-sinensal (17.7%) in C. verbenacea and ?-pinene (23,1%), ?-3-carene (32.1%) and limonene (16.9%) in S. terebinthifolius were reported. In biological tests, EOs showed toxic effect on cowpea-weevil life cycle, inhibiting over 80 and 98% oviposition and new insects emergence, respectively, except for C. verbenacea EO. DOI: 10.5935/1984-6835.20150142A infestação de insetos durante o armazenamento do feijão-caupi (Vigna unguiculata) é um obstáculo econômico a agricultura. Neste contexto, foi proposto um teste em escala laboratorial, objetivando investigar o potencial fumigante dos óleos essenciais (OEs) de Ocimum gratissium, O. basilicum, Cymbopogon nardus, C. citratus, Lippia alba, Mentha arvensis, Schinus terebinthifolius e Cordia verbenacea no controle do ciclo de vida do caruncho do feijão-caupi (Callosobruchus maculatus). Assim, os OEs foram extraídos e analisados por CG/EM, depois foram usados para avaliar a mortalidade, a postura de ovos e emergência de novos adultos. Como resultado da análise dos OEs observou-se os compostos: linalol (32,8%) e eugenol (48,1%) para O. basilicum; eucaliptol (14,8%) e eugenol (74,5%) para O. gratissimum; acetato de mentol (10%) e mentol (73,3%) para M. arvensis; citronelal (50,3%) e nerol (10,8%) para C. nardus; citral (75,8 e 87,1%) respectivamente para C. citratus e L. alba; ?-santaleno (35,8%) e ?-sinensal (17,7%) para C. verbenacea e ?-pineno (23,1%), ?-3-careno (32.1%) e limoneno (16.9%) para S. terebinthifolius. Nos testes biológicos, os OEs apresentaram efeitos tóxicos sobre o ciclo de vida do caruncho do feijão-caupi, inibindo acima de 80% a postura de ovos e mais que 98% a emergência de novos insetos, exceto o OE de C. verbenacea. DOI: 10.5935/1984-6835.2015014
