VI.-LOCAL SURVEYS FOR THE ABATEMENT OF MOSQUITO NUISANCES AND THE SUPERVISION OF ANTI MOSQUITO MEASURES AFFECTING MOUNT KELLETT, POKFULAM, ETC.
134. Anophelines have been seldom found to cause mosquito nuisance in this Colony, the common culprits being the Culicines—C. fatigans, A. (S) albopictus, and A. (F) togoi.
135. In areas where there is a likelihood of malaria being contracted, the Culicine pest has its uses, as it compels residents, especially servants, to make use of mosquito nets and thus the chances of contracting malaria are considerably lessened.
136. C. fatigans and A. (S) albopictus often breed in receptacles containing water in or around houses, occupied or unoccupied. Chinese villages and settlements of market gardeners swarm with them, unless there is a trained and efficiently supervised staff to deal with the situation. C. fatigans often breeds in septic tanks, and in stream pools and wet cultivation when the water is polluted. A. (F) togoi favours pools by the seashore.
137. During the year, complaints of mosquito nuisances were received from the R. A. F. Kai Tak, Diocesan Boys' School, Fanling Golf Club, Tai How Wan (Telegraph) Bay, Government House, Stanley Gaol, Kowloon Hospital, Torpedo Station Laichikok, Gascoigne Road, 25 The Peak, and Gap Road.
138. At Telegraph Bay and Laichikok the mosquitoes causing the nuisance were A. (F) togoi, at 25 The Peak A. (S) albopictus, in the other instances C. fatigans. Recommendations were made for dealing with the breeding places.
139. Anti-mosquito work was carried out at Mount Kellett and Pokfulam, also at various other places already mentioned in connection with anti-malarial operations.
Mount Kellett (Peak).
140. On the western side of the Mount Kellett ridge is a stream which flows into Mount Kellett Bay. Its lower portion is polluted with drainage from cattle byres.
141. C. fatigans larvae were formerly found in enormous numbers in the polluted pools but none were found above the pollution. Since 1934 oiling has been regularly carried out in the stream after removal of stones and boulders.
142. On the eastern side of Mount Kellett ridge is a stream flowing into Aberdeen Bay and polluted by drainage from pigsties, cesspits, etc. C. fatigans larvae formerly abounded in
