Observations on the physiology of adult anophelines in Asia.
Some recent physiological observations made in Afghanistan, Ceylon and Burma on adults of Anopheles culicifacies and A. aconitus are described. The specimens from Ceylon and Burma, in particular, showed a peculiar physiological process in which, at the beginning of the dry season, the coagulated, dark red, and almost desiccated stomach contents indicated a period of partial quiescence. As there were in most cases no signs of apparent growth of the fat-body, it appeared that a hitherto undescribed form of physiological behaviour occurred under certain climatic and seasonal conditions.
