Efficacy of essential oil of aromatic plants against immature stages of Callosobruchus maculatus Fab. and Bruchidius atrolineatus Pic. (Coleoptera-Bruchinae)

Toufique Bello Mariama, Ali Doumma

In this study, lethal effect of three essential oils extracted from aromatics plants, Ocimum basilicum, Ocimum gratissimum and Cymbopogon giganteus on immature stages of Callosobruchus maculatus (F.) And Bruchidius atrolineatus P. (Coleoptera-Bruchinae) are compared. For this; neonate larvae, fourth instar larvae and pupae of each species are treated with 6.25 µl; 12.5µl, 25µl and 50 µl oil of both plant. Results reveal the susceptibility of all stages of the two bruchids species to fumigation with essential oil of Ocimum basilicum, Ocimum gratissimum and Cymbopogon giganteus. Oil. Regardless to the aromatic plant, Adult emergence decreased significantly as oil concentration amount increased. For both species neonate larvae seems to be more susceptible. The study also indicates the susceptibility of C. maculatus immature stage to the three essentials oils compared to those of B. atrolineatus. Besides that, O. basilicum and Cymbopogon gayanus essentials oils were more effective than essential oil of O. gratissimum.
