48. Catches were also done from time to time in the course of malarial investigations, as the presence of A. minimus and A. jeyporiensis in a locality, especially in the rainy season, can often be determined more readily by searches made in the right type of buildings than by larval surveys, provided that these buildings are within flying distance of breeding places. Results of catches are given in accounts of these investigations.
Dissections of Mosquitoes for filaria.
49. Mosquitoes obtained from Shing Mun Camp, Little Hong Kong, and elsewhere were examined for larval filaria. The results are shown in Table VIII.
Precipitin Reactions.
50. A full report upon the material sent to Dr. Toumanoff, Chef du Laboratoire d'Entomologie de l'Institut Pasteur de Saigon, during the years 1934, 1935, has been furnished by him in his publication "L'Anophelisme en Extrême Orient". The results extracted are given in Table IV and are of the utmost importance and interest.
51. As Dr. Toumanoff went to Europe on leave in 1935, no further material was forwarded to him. During the present year, the Government Bacteriologist was good enough to arrange for the preparation and supply of certain anti-sera for the use of the Bureau; tests were afterwards carried out under the direction of the Acting Malariologist on mosquitoes caught in various places. The results are given in Table V.
52. The mosquitoes obtained from Pokfulam were taken at night in the Dairy Farm cattle byres; those from the pigsties at Little Hong Kong and Kowloon Tong were also obtained at night. All other mosquitoes were taken in day catches.
53. At Shing Mun, with the exception of a few dogs whose European owners resided in screened houses and about a dozen goats kept by the Indian police, there were no animals within half a mile of the Camp; attempts had been made to render the coolie lines mosquito-proof. From the precipitin results obtained, it would seem that in the absence or scarcity of suitable animals, A. maculatus, A. hyrcanus, A. minimus, A. jeyporiensis feed upon man.
54. The great majority of Anophelines captured at Wo Li Hop and Sheung Kwai Chung were taken in dark, ill-ventilated village cow byres and pigsties; those at Shek O from cow byres only, as none could be obtained from the village houses or pigsties.
