The study of the effects of (fig. 1) on mosquito development reported in 1928 (6) has been continued and expanded during the past season. Our investigations were directed along five principal lines: () Continued studies of the effects of on larval development under experimental conditions. () A survey of a portion of the central New York area to determine the distribution of spp. and their effect on mosquito density. () The introduction of into various types of ponds, marshes, etc., to study its rate of growth and effect on future mosquito breeding. () A continued study of the food (plankton) in ponds and typical mosquito breeding pools. () The effects of other aquatic plants on the larvae of .

The results of this season's work can be presented best under these five headings.
