Borah N, Phukan SC, Islam S, Tamuli SM and Rajbongshi P

A survey was conducted in seven districts of upper Assam for a period of one year from June, 2016 to May, 2017 to study the prevalence of ectoparasites of domestic ducks in upper Assam. A total of 675 ducks, comprising of 595 live ducks procured from the study areas and 80 dead ducks brought for post mortem examination to the District Diagnostic Laboratory and Head Quarters of Veterinary Officers in upper Assam, were thoroughly screened for the presence of ectoparasites on their body surfaces. Morphological study of mounted ectoparasite specimens were identified as per the keys and descriptions provided by Sen and Fletcher (1962), Soulsby (1982) and Hernandes (2015). Out of total 6 75 numbers of ducks examined, 467 ducks were found positive for different ectoparasites showing the overall prevalence of 69.19 per cent. Ducks from Gaurisagar of Sibsagar district Lahowal of Dibrugarh district showed highest (92.86%) and lowest (58.82%) prevalence for ectoparasites. Five different lice and two different types of mites were recovered from different body parts of duck, of which infestation with Lipeurus caponis (13.33%) was highest followed by Menopon gallinae (12.74%), Menacanthus stramineus (10.67%), Columbicola columbae (8.44%), different feather mites viz. Dubininia melopsittaci, Megninia ginglymura and Bdellorhynchus sp. (5.19%), Goniodes sp. (3.70%) and larva of Trombiculid mite (0.89%), respectively. The three feather mites, larva of the Trombiculid mite and Columbicola columbae were first time reported in ducks from Assam.
