Abstract

Studies conducted on the bionomics of the pteromalid parasitoid, Trichomalopsis apanteloctena Crawford indicate that the reproductive ability of the parasitoid is hindered by the male during oviposition period. The hindrance was caused by the male either by chasing for mating or by antennal encounters during oviposition. The mean fecundity of the female in the presence of male was lower and in the absence it is higher. The mean sex ratio was higher in isolated females than those females that were mixed with male.
