A study was conducted to evaluate the role of bio-physical traits of ber, Ziziphus mauritiana fruits on varietal preference of stone weevil Aubeus himalayanus Voss (Curculionidae: Coleoptera) infestations. Seven popular Ziziphus varieties was evaluated for their bio-physical traits including fruit size, fruit shape, average fruit weight, fruit texture and pulp stone ration (PSR) using standard procedure. Corresponding per cent fruit infestation of stone weevil also recorded. Results revealed that, bio-physical characters influences fruit infestation by stone weevil. Among the parameters estimated, the pulp stone ratio (PSR) found to be most critically influencing factor for weevil preference for infestation. Of the seven cultivars tested, CV Banarasi Karaka was relatively less attracted to fruit weevil and it was attributed due to bio-physical factor, low PSR ratio. This cultivar can be utilized as a source of resistance to ber stone weevil in ber improvement programme.
