abstract
Present investigation was carried out to study the relation of geographical distribution with biological attributes and genetic variability of Eocanthecona furcellata thriving in different crop ecosystems of North-Western Himalayas, India. The study was conducted on seven diverse locations of Uttarakhand and the result showed no significant differences in biological attributes and predatory efficiency between the populations of predatory bug of different locations. In the study of genetic variability, similarity coefficient of cluster analysis of individual predatory bug from high hills to plain areas was ranged from 0.07 to 0.77. The overall 131.55 bands were obtained from 5 primers and out of them 8 bands were monomorphic. RAPD primer EF6 showed highly efficient in determining the polymorphicity within species. Results indicated that E. furcellata was present in all seven diverse locations and it had adapted different climatic conditions to survive with at par predatory efficiency. Hence, utilization of native population of this potential predator could be effective in biological control programme for effective management of insect pests in Western Himalayas of Uttarakhand.
