RESUMEN
Data on malaria incidence and prevalence as well as on abundance of anopheline species collected in Jairampur, Arunachal Pradesh, show that P. falciparum contributed 27.59% of the total positive cases, most of these being recorded during July to September. Of the twelve anopheline species recorded, Anopheles maculatus was the most predominant comprising 54.32% of the total collection. Other common species were An. peditaeniatus, An. philippinensis and An. kochi in order of decreasing proportion. An. dirus, the known vector, was collected in the whole-night human bait catches (indoor) but in low numbers. An. philippinensis is implicated as another potential vector, and changes in anopheline/vector fauna are attributed to ecological succession.
