A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) during Kharif and Rabi 2020-21. A total, 103 soil samples were collected from different habitats, viz., fruit crops, field crops and fallow land of the AAU campus, Anand. Out of these, three were found positive and collected from three different locations, i.e., Horticultural farm (Mango), Veterinary College Garden and International Agri-Business Management College. The frequency of occurrence of these nematodes was 2.9 per cent and they belonged to the genus Steinernema. Nematode cultures from different locations were considered isolates and designated Steinernema sp. (AAU St-1), Steinernema sp. (AAU St-2) and Steinernema sp. (AAU St-3). Among three, Steinernema sp. (AAU St-1) was successfully maintained under laboratory conditions. Based on the morphometrics, Steinernema sp. (AAU St-1) was found similar to Steinernema ritteri.EnglishThesis
