Since the discovery by Barber and Hayne (1921) of the lethal effects of Paris green upon anopheline larvae, most of the quantitative studies made in this country on the distribution of dust particles have been in connection with aeroplane dusting (King and Bradley, 1926; Williams and Cook, 1927; Le Prince, et al., 1927; Watson, 1936, and Kiker, Fairer, and Flanary, 1938). Observations on the larvicidal efficiency of various brands of Paris green, used in different proportions with diverse diluents and discharged laterally from power or hand-dusters were reported by Gill, Kiker and Sims (1929) and Le Prince and Johnson (1929). The use of such ground equipment is relatively common in the Southern states, yet, with the exception of the last-mentioned papers little has been done to explore its limitations. A considerable literature exists on the use of these dusters in orchard and crop dusting but the objectives and circumstances of this type of dusting vary so from those of anti-mosquito applications that its significance in malaria control considerations is restricted.
