Storage, transport and application are major hurdles in the widespread acceptance of entomopathogenic nematodes (EPNs) by the growers. We hypothesized that EPNs can be delivered directly in the potting media circumventing the application hurdles. We also hypothesized that EPNs delivered through the infected host cadavers will be more stable than an aqueous suspension in the potting media. We found that in aqueous application, nematode survival declined rapidly within 2 months for both Steinernema carpocapsae and S. feltiae. Virulence remained constant (~42%) for S. carpocapsae but decreased for S. feltiae (31% and 8%) after one and two months. The nematodes applied through cadavers were found viable even after three months of storage in the potting media. Virulence of nematodes delivered through Galleria mellonella and Tenebrio molitar cadaver treatments was 58% and 28% respectively after 3 months. We then compared survival of S. carpocapsae applied through either G. mellonella cadavers or an aqueous suspension to the potting media at 20%, 30%, 40% and 50% moisture levels. Highest survival was observed at 20% moisture content in the cadaver application after 2 months. Virulence was above 50% in all the cadaver treatments for 2 months. Therefore, the results support our hypothesis that nematodes delivered through cadavers coupled with low moisture content of the media survive better than the nematodes applied as aqueous suspension.
