Abstract

                                Peak occurrence of green leafhoppers (GLH) was observed during September and October months of the three years 1991 93. The species composition in light-trap and field collections revealed that Nephotettix virescens dominated over N. nigropictus. The seasonal incidence of GLH in the three defined seasons of Cauvery Delta Zone revealed that early planting of the crop in Kuruval season i... July 25 recorded low incidence of GLH than the late planted crop. The early as well as late planting of samba and thaladi season was susceptible to GLH. Among the weather factors. relative humidity and minimum temperature influenced the pest population.

Key words : Green leafhopper, species, rice, season, field population, light-trap, correlation, regression
