Abstract

A modified trapping technique for the entomopathogenic nematodes was tested for its efficacy in recovery of naturally occuring insect parasitic nematodes, optimum time of removal of baited traps from the soil and at the same time prevention of attack by predatory ant,Solenopsis geminata (Fabr.). The highest nematode recovery (13.5 %) and the least ant attack were achieved on fourth day of trapping. Modified trapping technique was found effective in the prevention of predatory ant attack which subsequently increased the efficacy of nematode recovery.
