Six bat species (ptenochirus jagori, Cynopterous brachyotis. Macroglossus minimus. Ptenochirus minor, Rousettus amplexicaudatus, and Haplonycteris fischeri) were examined for presence of ectoparasites. Three species of ectoparasites (Eucampsipoda sp., Leptocyclopodia simulans, and Leptocyclopodia ferrarii) of the family Nycteribiidae, order Diptera were collected. All bat species harbored ectoparasites except M. minimus. The highest infestation occurred in P. jagori, while the least infestation was observed in C. brachyotis, P. minor, and H. fischeri. The most abundant ectoparasites was the female L. simulans at 31.37% while the least abundant was the female L. ferrarii at only 7.84%. Prevalence was highest in R. amplexicaudatus and lowest in P. minor. Results from t-test revealed that the age and gender of the host do not influence the infestation by the ectoparasites. The Chi square test for Independence indicate that there is no relation between the age and the gender of the host in harboring ectoparasites.
