nematode formulation

Entomopathogenic nematodes can be applied through infected insect host cadavers by Ganpati Jagdale

Entomopathogenic nematodes are generally applied as infective juveniles in aqueous suspensions using various techniques including irrigation systems, sprayers and water cans. These nematodes can also be applied through infected host cadavers. It has been demonstrated that the application of nematode infected insect cadavers can provide superior nematode dispersal (Shapiro and Glazer, 1996), infectivity (Shapiro and Lewis, 1999) and survival (Perez et al., 2003) when compared with the nematodes that applied in aqueous suspensions. Please read following literature to learn more about the advantages and disadvantages of applying nematodes through infected insect cadavers.
