          Abstract

          Muchas especies de plantas superiores producen metabolitos secundarios, a los cuales se les atribuye funciones ecologicas y de defensa contra microorganismos y fitofagos. El objetivo de este trabajo fue conocer la susceptibilidad de larvas de Ae. aegypti y An. albimanus a dos tipos de extractos de acetogeninas obtenidos de semillas de Annona muricata. Las dos especies de Culicidae estudiadas fueron altamente susceptibles a ambos tipos de extractos bajo condiciones de laboratorio. Las concentraciones letales medias (CL50) para los extractos polar, no polar y mezcla de acetogeninas para Ae. aegypti fueron de 74,7 ppm, 236,2 ppm y 20,3 ppm, respectivamente, mientras que en An. albimanus fueron de 0,8 ppm, 16,2 ppm y 1,4 ppm. Se presentan las dosis diagnosticas y su respectivo rango de variacion. Las diferencias entre la mortalidad producida por los extractos no fueron estadisticamente significativas. Una eleccion para su utilizaciòn, podra ser determinada posteriormente cuando se evalùe la residualidad de ambos compuestos y la relaciòn costo beneficio.

          Many species of higher plants produce secondary metabolites, to which ecological functions and defense against microorganisms and phytophages are attributed. The objective of this work was to understand the susceptibility of Ae. aegypti and An. albimanus larvae to two types of acetogenins extracts obtained from seeds of Annona muricata. The two species of Culicidae studied were highly susceptible to both kinds of extracts under laboratory conditions. The mean lethal concentrations (CL50) for the polar, nonpolar and mix of acetogenins extracts for Ae. aegypti were 74,7 ppm, 236,2 ppm and 20.3 ppm, respectively, while in An. albimanus they were 0,8 ppm, 16,2 ppm and 1,4 ppm. The diagnostic doses are presented with their respective range of variation. The differences in mortality produced by the extracts were not statistically significant. An option for its use could eventually be determined when the residuality of both compounds and the costbenefit ratio are, evaluated.

            Botanical derivatives in mosquito control: a review.

            A review on the reported uses of chemicals derived from botanical sources is presented, along with the part of the plant used for extraction, the mosquito species studied and the bioactivity observed for 344 plant species. Examples of phytochemicals evaluated against mosquitoes as general toxicants, growth and reproduction inhibitors, repellents and ovipositional deterrents are given. The effects of mosquito species and life stage specificity, solvents used for extraction, phototoxic activity and the geographical source from where the plant compounds are derived are discussed.
