One Season of Anti-Malarial Work at Pasighat

malaria, identified the anophelines responsible and incriminated the Mora-Lalli to be their breeding place. He recommended, among other measures, oiling the stream, clearing the station of jungle from the Dihang to the MoraLalli. filling in of puddles and pools and the prophylactic issue of mosquito-nets and quinine where practicable. The anophelines identified by him were the following:?A. macnlatus, sinensis, fuliyinosus, barbirustris, aitkcni, ncoaitkeni, lisloni and culiciformis. Of these A. macnlatus predominated. For some obscure reason the task of oiling was left to a non-medicai department, the officers of which had no training for this sort of work. They were using a mixture of crude and refined kerosene oils which was poured into kerosene oil tins with a hole knocked at the bottom and fitted with a gauze wick. These wicks lost their capillarity in a short time and then acted as plugs, preventing any dripping. In addition the actual breeding places were not found out and dealt with.
