Abstract

Entomopathogenic nematodes in the families, Steinernematidae and Heterorhabditidae are obligate parasite of many insects and two species STEINERNEMA SP. and Heterorhabitis bacteriophora have been used efficiently for biological control of pests. In order to evaluate the efficacy of ENTOMOPATHOGENIC NEMATODES collected from POLYPHYLLA OLIVIERI larvae in 1998-1999, field expriments arranged in a completely randomized block design. STEINERNEMA SP. and HETERORHABDITIS BACTERIOPHORA, nematodes were applied with initial inoculum levels of 0, 2.5×105, 5×105 individual per m2. The experiments were conducted in 6×15 cm pots containing a sandy-loam soil mixture. Nematodes at the mentioned rates suspended in 20 cm3 distilled water were sprayed on the surface of the soil in the pots. After releasing a third instar larvae in each pot, they were covered with gauze. After 14 days dead larvae were counted in the pots. The results indicated that STEINERNEMA SP. and H. bacteriophora at the rate of 5×105 individuals per m2 were able to parasitize 33.33% and 45.37% of the pest larvae respectively.
