Abstract
Adult Callosobruchus maculatus (F.) were introduced into cowpea seeds which were stored in containers with volatile oils derived from Mentha avrensis, M. piperata, M. spicata and Cymbopogon nardus. The numbers of eggs laid, a dult mortality, adult emergence and subsequent seed damage were studied for four months. All oils significantly influenced all parameters (P < 0.05) a nd results with different parameters were generally parallel. Significant d ifferences for at least some time/parameters combinations indicated an orde r of potency of M. spicata > M. piperata > M. arvensis > C. nardus. (C) 200 0 Elsevier Science Ltd.
