The entomopathogenic nematode Steinernema feltiae strain Ustinov Russia used on potato foliage to control larvae of the Colorado potato beetle, Leptinotarsa decemlineata.(Say.) (Coleoptera: Chrysomelidae) Formulations of agar at 4%, 2%, 1% and 0.5% concentrations were tested as anti-desiccant compared to the application of nematodes only in water (control) alone. The agar formulation significantly improved efficacy to nematodes survival as compared to water when 100 infective juveniles’ nematodes (IJs) in 20 ml of agar formulation were tested for each concentration. In conclusion, the agar formulation enhanced nematode survival, delayed drying for a relatively longer time, provided a suitable environment and increased the possibility for nematodes to invade their host on the foliage.
