Annonaceae cause mortality in Aedes aegypti (Linnaeus, 1762) (Diptera: Culicidae)

Abstract

This work aimed at to evaluate the effect biocidal of Annona crassiflora, A. dioica, A. mucosa, A. coriacea and Cardiopetalum calophyllum in different solvents on larvae of A. aegypti after 24 hours of exhibition, being the data submitted to the variance analysis and test of comparison of averages. The lethal concentration (LC50) it was certain for Probit. A. coriacea in methanol and hexano and A. mucosa in methanol presented 100% of mortality in 0,1mg/mL, with LC50 0.007, 0.007 and 0.010, respectively. A. crassiflora presented superior mortality to 90% in 1.0 mg/mL, in the extract rude methanolic (CL50 0.100), hexane (LC50 0.507), dichloromethane (LC50 0.185) and in the fraction hexane (CL50 0.433). The fractions hidroalcoolica, etila acetate and chloroform didn’t cause mortality. In the species A. dioica and C. calophyllum the mortality was subscript to 50%. Therefore, A. crassiflora, A. coriacea and A. mucosa, in the solvents methanol and hexane are promising species for the development of futures biocides in the combat to the dengue vector.
