Abstract:

Population status of sugarcane leaf hopper, Pyrilla perpusilla (Walk.) and its natural enemies were studied at Kabirdham District of Chhattisgarh. During the year 2016-17 and 2017-18, the population of sugarcane leaf hopper, P. perpusilla (Walk.) was first occurred second fortnight of July with 1.63 and 0.64 eggs, 0.07 and 0.04 nymphs and 0.04 and 0.05 adults leaf-1 and gradually decreased first fortnight of January with 1.42 and 0.84 eggs, 0.80 and 0.47 nymphs and 0.32 and 0.24 adults leaf-1, respectively. Second fortnight of September peak activity was noticed with 31.27 nymphs and 5.93 adults leaf-1 but in case of eggs 9.44 eggs leaf-1 at first fortnight of October during the year 2016-17. Similarly, during the year 2017-18 peaks was observed first fortnight of October with 27.72 nymphs and 5.94 adults leaf-1 but eggs was 9.24 eggs leaf-1 during second fortnight of October. Two natural enemies viz. egg parasitoid, Tetrastichus pyrillae (Chrawford) and ento-pathogenic fungus, Metarhizium anisopliae (Metschn) have play role to suppress the population of P. perpusilla. The maximum egg parasitization by T. pyrillae was noticed during second fortnight of December with 43.12 and 45.19 per cent. Parasitization by M. anisopliae was high during the first and second fortnight of October during the year 2016-17 and 2017-18 with 11.63 and 16.31 per cent.
