Dubas bug, Ommatissus lybicus is a key sucking pest of date palm in Balochistan. Three main commercial date palm cultivars, viz, Kehraba, Jan Sore and Mozavati were selected for present study. Suceptability of cultivars were scaled by considering number and size of honeydew droplets. Count of honeydew droplets excreted by dubas bug (population) was highly significant among tested cultivars over the seasons and various life stages. Irrespective of cultivars, among all life stages maximum (7.1) and minimum (2.8) number of honeydew droplets were excreted by 5th nymphal instar and adult stages of dubas bug respectivelly. Mean diameter of honeydew droplet (spot) size of 1st instar, 5th instar, and adult stages was 0.15, 0.60, 0.65 mm, with a relative % age of 6.0, 23.5 and 25.4, respectively. Mean diameter of honeydew droplet was 0.426 mm and 0.428 mm in spring and summer 2009-10, respectively.The size of honeydew droplets was larger in Jan Sore compared to Mozavati and Kehraba cultivars.
