Abstract:
 
The distribution of the rats’ ectoparasites in Bangkok and Nonthaburi was studied. The result showed that the average percentage of trapped rats in 11 representative slum areas was 20.3 and the percentages of species density were the following : Rattus exulans 65.4, R. norvegicus 16.4, R. rattus 13.4, Suncus murinus 4.8. There were only 2 Orders of ectoparasites, flea and mite. Fleas were oriental rat fleas, Xenopsylla cheopis, that were of great importance as vectors of plague. Flea index value of these areas were between 0.01-0.94 and the average value was 0.45 Other ectoparasite was only mite, Laelap sp., that causes dermatitis, the percentage of mite infestation was 22.26.
