Abstract:
: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.
