Objetivo: Evaluar el riesgo ambiental de cuatro plaguicidas convencionales en los servicios ecosistémicos de la artropofauna terrestre en el cultivo de cacao. Materiales y Métodos: Se aplicó cipermetrina (T1), carbofurano (T2), oxicloruro de cobre (T3) y clorpirifos (T4) con una mochila fumigadora pulverizadora manual “Jacto PJ-16”, en una finca de cacao en San Martín, Perú del 01 de enero al 17 de febrero del 2019 (7 semanas). Se colocaron cuarenta trampas de caída por cada tratamiento para capturar a la artropofauna terrestre. Resultados: Para la evaluación global, se encontraron diferencias significativas en los depredadores para el índice de riqueza específica (S) entre T2 y T3 (valores más bajos), en comparación con los otros tratamientos; mientras que en el índice de Margalef (Dmg), se encontraron diferencias significativas entre T3 (valor más bajo) y los otros tra...

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...
