Abstract

This article studies the biological efficacy of two types of entomopathogenic nematodes (Steinernema carpocapsae and Heterorhabditis bacteriophora) against the larvae of cotton bollworm using different concentrations (200 YL/ml and 500 YL/ml). The results indicated that both nematode species caused larval mortality, with H. bacteriophora demonstrating the highest efficacy when applied at a concentration of 500 YBL/ml.
