Barkat Hussain, Abdul Rasheed War and Douglas G Pfeiffer
Experiments were conducted from 2012-2014 to develop the georefrenced maps on cole crops for observing foliage damage index (FDI) and hot spots for cabbage butterfly in Ganderbal, Budgam, Anantnag, Srinagar, Kulgam, Baramulla and Pulwama districts of Kashmir Valley. Data revealed that, among the locations, Chadura (Budgam) recorded highest (3.60) and lowest from Wanpow (Anantnag) (1.80), FDI on Kale, respectively. Whereas, among the locations, during two survey periods, Zazun (Ganderbal) recorded the highest (100 and 90) and Arampora (Kulgam) recorded the lowest (10 & and 20) butterfly index, respectively, on geographic information system (GIS) Map. Among the aspects, north-western direction, and highest elevations recorded highest butterfly numbers.
