The cocoa crop (Theobroma cacao), is pollinated mainly by Forcipomyia spp. (Diptera: Ceratopogonidae). The objective was to evaluate the environmental risk of four conventional pesticides: cypermethrin, carbofuran, copper oxychloride and chlorpyrifos, used in the cultivation of cocoa on the pollinator, Forcipomyia spp. The environmental risk was evaluated by analyzing the abundance index of Forcipomyia in the town of Sangamayoc, Barranquita district, Lamas province, San Martín region, Peru. The individuals were obtained by incubation and capture in emergency boxes with cocoa litter that encountered the four pesticides over three evaluations. The results show that chlorpyrifos presented the highest environmental risk on the abundance of Forcipomyia, followed by cypermethrin, carbofuran and copper oxychloride. In the first evaluation, a decrease in pollinator abundance was observed, follo...

Introducción: Muchas plantas dependen de un tipo de polinizador específico, y si éste es alterado no se logrará que la planta del cultivo produzca el fruto o presente las mismas características. Este es el caso del cultivo cacao (Theobroma cacao L.), cuya flor presenta una estructura que permite que solo sea polinizada por insectos del orden díptero, de la familia Ceratopogonidae, principalmente del género Forcipomyia. Sin embargo, este polinizador podría estar viéndose afectado debido a que, en los últimos años, el cultivo de cacao ha sufrido un ataque más intenso de plagas, y por lo tanto, un mayor uso de pesticidas, de los cuales no se ha estudiado el impacto sobre su polinizador. Objetivo: Evaluar el riesgo ambiental de la aplicación de cuatro pesticidas convencionales utilizados en el cultivo de cacao (cipermetrina, carbofurano, oxicloruro de cobre y clorpirifos) sobre ...
