Within biotic communities, nematodes are important environmental indicators of conservation of agricultural soil systems. The objective of the study was to isolate and identify nematodes in 10 land use systems of the Yurimaguas district, Peru. The collection of samples from each soil system was random, 10 soil samples, collected from an approximate depth of 15 cm, later the isolation of the samples was carried out in sterilized containers, where they were divided into two subsamples for the placement of 5 to 10 moth larvae (G. mellonella), which were kept in environments between 20 and 25 °C for one week; After the incubation period, the presence of entomopathogenic nematodes was evaluated. The presence of nematodes of the genus Heterorhabditis and Steinernema was found in land use systems of cocoa (Theobroma cacao L), cassava (Manihot esculenta) and plantain (Musa paradisiaca) crops. The identification study of native entomopathogenic nematodes in the different land uses of Yurimaguas contributes as a proposal for the biological control of pests in crops of economic importance.
