COMPARATIVE STUDIES OF HERPETOMONADS AND LEISHMANIAS

Abstract

Nine strains of herpetomonads have been isolated in pure culture from eight varieties of insects, and three strains from two species of plants. Four of the cultures were derived from latex-feeding insects (Oncopeltus fasciatus, Oncopeltus sp. ?, Lygæus kalmii) and three from latex plants (Asclepias syriaca, Asclepias nivea), two from mosquitoes (Culex pipiens and Anopheles quadrimaculatus), one from the house fly (Musca domestica), and two from bluebottle flies. In addition impure cultures have been obtained from Oncopeltus cingulifer and from its plant host, Asclepias curassavica.
