This paper reports the compatibility of native species of entomopathogenic nematode, Steinernema abbasi with pesticides (ten insecticides, six fungicides and six herbicides) that are registered for agricultural use in India. It was investigated how these chemical pesticides affected the viability and virulence of infective juveniles (IJs) of S. abbasi when exposed directly to them at recommended concentrations. After the IJs were subjected to the intended pesticidal concentrations, which was highest recommended dose specific to the type of pesticide, up to 72 hours, data on their survivability was documented. Thereafter, infectivity of the surviving IJs was documented by inoculating them on 4th instar larvae of Galleria mellonella under laboratory conditions. With the exception of cartap hydrochloride (100%) and acetamiprid (19.1%) among insecticides, carbendazium + mancozeb (23.5%) and tricyclazole (14.1%) among fungicides and pendimethalin (19%) and 2, 4 - D sodium salt (11%) among herbicides, all the tested pesticides showed less than 10% nematode mortality after 72 hours of exposure. The tested pesticides had no negative effect on the pathogenicity of IJs, since 100% mortality of Galleria mellonella larvae was observed in each treatment after 72 hours of inoculation. The experimental findings of this work are noteworthy in light of future prospects for combination treatments under the Integrated Pest Management programme against economically important insect pests of crops.
