none Enter The intra-specific variation among the different geographic populations of Cotesia flavipes (from India), with respect to their host searching ability was evaluated under laboratory conditions. Intra-specific variation was observed among the different populations with respect to host searching ability. The searching efficiency in terms of number of larvae parasitized was higher in 1 cu.ft cage than in 3 cu.ft cage in all the populations, irrespective of the geographic location. The searching efficiency was maximum in the parasitoid population obtained from Shimla, Dindigal and Bangalore, while it was on par with each other in the populations from Coimbatore, Devganahalli, Malur and Aurangabad. Parasitoid strains with higher response to plant odours or an intercrop that emits significant levels of odours could increase attraction of the parasitoid to control stem borer larval populations in an integrated pest management strategies.
