“…They are the proven vectors of three human nematodes, Acanthocheilonema perstans (Garnham and Harper, 1944;Hopkins, 1952;Hopkins and Nicholas, 1952;. Kershaw, 1950;Nicholas, 1953a, Nicholas, et al, 1953Roman, 1941;Sharp, 1927Sharp, , 1928; Acanthocheilonema streptocerca (Chardome and Peel, 1949;Henrard and Peel, 1949;Van Den Berghe and Chardome, 1952); and Mansonella ozzardi (Briceño-Rossi, 1949;Buckley, 1933Buckley, , 1934aBuckley, , 1934bO'Connor, 1937;Romana and Wygodzinsky, 1950); but not of Onchocerca volvulus (Gibson and Ascoli, 1952). Various authors have suspected them to be vectors of fevers of undetermined origin (Huttel, et al, 1953;Loughnan, 1921;Purcell, 1937;Stephens, 1923;Wanson, 1939).…”
