POTENSI NEMATODA ENTOMOPATOGEN Stelnemema carpocapsae (ALL STRAIN) SEBAGAI PENGENDALI HAMATANAMAN KUBIS Plutella xylostella Linn.

The research was conducted based on cabbage pest Plutella xylostella difficult to control, because this pest resistant to synthetic chemistry insecticide. and Bacillus thuringiensis. One of the alternative control endeavored by using biological agent entomopathogenic nematodes. Entomopathogenic nematodes Steinernema carpocapsae (All strain), not only effective to control P. xylostella, but also friendly environment insecticide. The purpose of the research was to know the potential of entomopathogenic nematodes Steinernema carpocapsae (All strain) to control pest of cabbage P. xylostella. This experiment was done on Faculty of Agriculture, Jember University from March 2002 until May 2002. In this researh, experiment was on Fully Randomized Design. The result of this research indicated that Steinernema carpocapsae more effective to control larvae 3rd - 4th instar of P. xylostella than larvae 1 5t - 2nd instar and pupae
