abstract
With a view to establish a proper control program for the pest of dried fish, an investigation was taken under laboratory condition on life cycle parameters of Dermestes frischii on three most consumable and popular dried fishes (Harpadon nehereus Hamilton 1822; Sicamugil cascasia Hamilton 1822 and Macrobrachium lamarrei Edwards 1823). The parameters that have been taken under investigation on the above mentioned dried fish substrates were developmental period, size and weight of larvae and pupae, adult longevity, fecundity and fertility of Dermestes frischii. Incubation and pupation period were estimated as insignificant (p>0.01) among all dried fishes whereas the highest larval period was revealed from M. lamarrei. The result obtained from this experiment expressed a short developmental period for H. nehereus and S. cascasia against that of the M. lamarrei. The mean fertility screened from H. nehereus, S. cascasia and M. lamarrei was ranged between 81.2 ± 0.80 to 86.2 ± 1.77. There was a sharp peak for mean fecundity from dried H. nehereus and also a sharp decline in mean fecundity for dried M. lamarrei. In case of pupal weight, the heavier pupae were recovered from S. cascasia whereas the lightest pupae were collected from M. lamarre. A significant (p<0.01) result was obtained from all three dried fishes for adult male female longevity of D. frischii. The present experiment specifies a good indication for host preference of Dermestes fischii and also initiates a proper control program for this pest of dried fish.
