54. These dissections were done during the malarious season of the year, and the results indicate that little or no malaria was being carried by A. maculatus, although it has been shown at the Bureau to be a good experimental carrier.
55. Unfortunately there are no closed pigsties in the immediate neighbourhood. There are pig yards with open air shelters, but it was not thought likely that Anophelines could be readily obtained from them.
Wong, Chok Hang Village (Little Hong Kong).
56. Catching operations were continued throughout the year. The locality is surrounded by hills on all sides except in the direction of the sea. A stream with several branches flows through it. A ravine which was formerly a rice swamp, drains into the main stream. At the end of 1933 most of this swamp was ditched and divided into rectangular plots for growing crops such as Indian corn, three or four small plots were left for rice growing; rice was also planted in such of the ditches as held water. During the present year no rice was grown.
In surveys done towards the end of the year, A. jeyporiensis larvae were found in good numbers in some of the ditches between the plots. The people of the village live in houses built of stone and roofed with tiles, the market gardeners in huts made of bamboo and roofed with thatch. All are engaged in growing crops and rearing pigs. The pigsties here are, as a rule, unsuitable as day time resting places for Anophelines owing to their exposure to wind and weather. No cattle are kept in the locality.
57. In 1931 a high spleen rate was found amongst the children and in 1932 a microfilaria rate of 12% was obtained from the examination of 106 people, the blood being taken at night.
58. From 8:30 a.m. until 11:30 a.m. collections were made by the catching coolie in two groups of huts on alternate days. These groups were situated north and south of Island Road, the northern group along the stream banks, close to places where A. minimus larvae were in abundance, the southern group about 440 yards down stream where the larvae of A. minimus were scarce.
59. Of A. minimus, 2872 were obtained in 153 morning catches done in the northern group or 18.77 per morning, 829 were collected in 151 mornings from the southern group or 5.49 per morning about one-third of the catch obtained from the northern group. It would thus appear that habitations closest
