Notes	The functional response to host density and mutual interference of an egg parasitoid, Anagrus incamatus Haliday, parasitizing eggs of Nilaparvata Zagem (Stal) were analysed. The behavioural response to varying host egg densities of this parasitoid was found to be fitted the Helling’s Type II functional response. By utilizing the Holling’s (1959) method, the handling time (Tn) and searching efficiency (a) were evaluated. This parasitoid was also found to possess some degree of mutual interference (m), follwing the Hassell and Varley’s (1969) model. In addition, ohservation on the sex ratio of the parasitoid’s progeny, with respect to the host egg and searching parasitoid densities available in the present study, showed that its ratio was rather constant, the females usually outnumbered the males, about 2 or 3 to 1.
