Abstract
Entomopathogenic nematodes (EPNs) are effective biocontrol agents for managing agricultural pests because they can rapidly kill their hosts in an environmentally friendly manner. This study aimed to explore and identify entomopathogenic nematodes (EPNs) in the highlands of Dlundung, Trawas, Mojokerto, and to analyze the relationship between vegetation density and population abundance. Soil samples were collected from two sites at different elevations: 980 masl (dense vegetation, NDVI 0.55) and 1020 masl (sparse vegetation, NDVI 0.23), using the soil baiting method with Tenebrio molitor larvae as bait. Isolation results revealed two genera of EPNs, Steinernema spp. and Heterorhabditis spp., distinguished by morphological characteristics and host cuticle coloration. EPN populations were higher in dense vegetation (29.51 IJ/mL) than in sparse vegetation (15.86 IJ/mL), although the difference was not statistically significant (p > 0.05). These findings indicate that both sites provide suitable environmental conditions for EPN development and have potential as local isolates for biological pest control. Keywords: Abiotic factors, biological control, morphometric analysis, pathogenicity
