The research investigates the effectiveness of physical
stressors in enhancing the infectivity of entomopathogenic nematodes, which
could be valuable for biocontrol applications in agriculture. Entomopathogenic
nematodes act as good bio-control agents to manage lepidopteran and coleopteran
pests. Steinernematidae and Heterorhabditidae are considered important families
in entomopathogenic nematodes. An invitro experiment was conducted to enhance
the efficacy of Steinernema glaseri using hot water and UV radiation on final
instar larvae of Corcyra Cephalonica. The results showed that the highest
number of larvae were infected at 35°C and 45°C of hot water immersion. Among
the UV-exposed larvae, the highest number of larvae infected was obtained by UV
exposure for 10 minutes. It is hypothesized that changes in the external layer
of cuticle allowed entomopathogenic nematodes to penetrate, resulting in
increased S. glaseri infectivity in the current study.
