Control biológico be larvas de Culex SP, mediante el uso de náyades de odonata en condiciones de laboratorio

Abstract

In the city of Bogotá Culex quinquefasciatus represent a problem for public health due to its sting can cause allergies and discomfort in humans and domestic animals. Therefore, its population control has been sought with different methods. Biological control with natural predators is one of the control mechanisms used, for which consumption was evaluated during the months of October to December of 2016 and the months of January and February of the 2017. The aim of this study was to evaluate the biological control of Culex sp. in their different stages (I, II, III and IV), by nymphs of the suborders Zygoptera and Anisoptera (Insecta: Odonata), commonly known as devil's horses and dragonflies. Taking into account related studies where it is shown that these can be an effective biological control, it was determined that the consumption is higher in Anisoptera than in Zygoptera and that the two suborders have a preference for stage II larvae.
