Abstract : The cabbage butterfly (Pieris brassicae) is a destructive pest of cruciferous crops. This study evaluated the efficacy of the entomopathogenic nematodes Steinernema feltiae and Heterorhabditis bacteriophora under laboratory conditions. Larvae were treated with different nematode concentrations, and mortality was recorded over 5–7 days. Both species caused significant larval mortality (70–90%). S. feltiae was more effective at lower temperatures (15–20°C), whereas H. bacteriophora performed better at higher temperatures (25–30°C). The results support the use of entomopathogenic nematodes as sustainable biological control agents.
