    Abstract

    Helicoverpa armigera is the major pest of tomato which causes fruit damage. Farmers are usually using a synthetic pesticide to control the pest, however it makes negative impact on the environment. One of the alternative control is using by biological agents which more environmentally friendly. Field trials evaluating the potential of biological pest control with entomopathogenic nematodes and entomopathogenic fungi were conducted in tomato cultivation. The treatment of pest control consisted of control (no treatment), the entomopathogenic nematode strains Steinernema carpocapsae with population density of 105 IJ/ml, entomopathogenic fungi Beauveria bassiana strain 725 with spore density of 109/ml , combination of B. bassiana strain 725 with spore density of 109/ml + S. carpocapsae with population density of 105 IJ/ml and insecticide (profenofos) with concentration of 0.2 mg/ml. The result of this research indicated (1) B. bassiana more effective to pressure the population of H. armigera because it’s host and geographically specific (2) S. carpocapsae less effective to decrease the production of damage fruit cause pest’s behavior and (3) Aplication of biological agents was able to decrease production of damage fruit. Key words : Biological control, entomopathogenic, fungi and nematode
