FN TRODUCTION
Due attention was given to the experimentation of jute crop in this part of the country when the Eastern Wing delinked permanently. In N.W.F,P. no pararnetrical assessment of the incidence of the pest species has been tackled so far in the past. ft was, therefore, considered necessary to scroe out the incidence of various pest species on jute. Anoints' flaw Fab. (13,17), Dasyckira mendosa Hub, (5), Earias arpreaviridis Walk. (5,6,7), E. insulana Boiled. (1,2,5,8,11,16), Erirproctis. dig 11 flats Walker (5,7), Spilosoina oblique:2 Walk. (3,4.5,9,10,12,1.4,15) and Spodopera litura Fab. (5,14) have been reported as pests of jute. The present report concerns with the initial assessment of the incidence of lepidop-terous pests on different cultivars of jute being cultivated at the Agricultural Research Institute Tarnab. Peshawar.
MATERIALS AND METHODS
Seed of the following jute cultivars were sown on June 2, 1R81, in lines 0.3 m apart, in randomised complete block design :-(A) Corchoras plitorius L. (B) eaPtilari4- L.
