 Abstract

 

The anopheline resistance to synthetic pesticides has led to the use of plant biocides as alternative biological and natural control strategies. The red variety of Capsicum annuum (Solanaceae), locally used to fight against insects was tested in this study for its insecticidal effect against aquatic stages of Anopheles gambiae s.l. mosquitoes. Fresh ripe fruits were crushed, and essential oil was extracted by hydro distillation in Clevenger-type apparatus. Seven working concentrations (0, 10, 20, 30, 40, 50, and 100 ppm) were tested against eggs, larval and pupal stages of An. Gambiae s.l. Overall, the hatching rates were low and decreased with the oil concentrations with median inhibitory concentration (IC50) of 13.735 ppm after 24 h exposure to C. annuum fresh fruits essential oil.  This oil revealed high larvicidal effect against third instars larvae (L3) of An. Gambiae s.l. with median lethal concentration (LC50) of 26.181 ppm and 19.643 ppm, respectively after 30 min and 1 h exposure. A pupicidal effect was also observed against pupal stages of An. Gambiae s.l. with LC50 of 27.303 ppm and 20.939 ppm, respectively after 30 min and 1 h exposure. Overall, this study revealed and confirmed the biological potentials of C. annuum fresh fruits essential oil as a safe tool to fight against eggs, larvae and pupal stages of An. Gambiae s.l. in areas where this insect is known as vector borne disease implicated in the transmission of malaria.
