The Bahamian Government was never able to establish a coordinated
laboratory such as these, but in the early 1930's it enlisted the help of J. G. Myers, a government entomologist, from Trinidad. Since 1950 it has relied heavily on the assistance of private entomologists from the United States, two of whom should be mentioned for their important work on the biology and control of Bahamas sandflies-Edwin A.
