Abstract
A new apparatus for feeding mosquitoes is described. It is constructed without special technique and easy of handling. The usefulness of the apparatus is demonstrated by a report on investigations into the effects of nucleotides on mosquito gorging and the development of the microfilariae from the jird peritoneal cavity and from the dog venous blood in Aedes aegypti. As a phagostimulant 10-3M ATP is the most effective of the nucleotides tested. The microfilariae from the jird peritoneal cavity have been proved to reach stage III (i.e. infective stage) as those from the dog, although the rate is lower in the former. It is also proved that the microfilariae develop to infective larvae in the mosquitoes which have not taken blood, serum or protein meals.
