Abstract

Parnara guttata (Bremer & Grey) was found to support the population of three different larval parasitolds, namely, Apanteles sp., an ichneumonid, a taehinid and one pupal parasitoid, Brachymeria sp. in paddy fields at Regional Rice Research Station, Khudwani, Anantnag, from July to October during Kharif 2003&2004. Total host parasitisation was averaged as 41.83 and 44.43 per cent during 2003 and 2004 respectively, and showed nonsignificant positive correlation (0.22 and 0.13) with the availability of host, during both the years. Among the parasitic community studied, average parasitism by Apatiteles sp, was found maximum in nature (23.26 and 24.7), followed by tachinid (8.7 and 8.38), Brachymeria sp. (7.33 and 8.1) and ichneumonid (2.55 and 2.63 per cent) during the corresponding years. Pattern of parasitism for individual parasitoid species was worked out in detail along with possible reasons of dynamic similarity and changes in their population.
