Notes on the natural Enemies of the Sugar-cane Froghopper (Tomaspis saccharina, Dist.) in Trinidad, with Descriptions of new Species

Abstract

From the formation of the Froghopper Investigation Committee in 1925, the chemico-ecological relations of the froghopper have engrossed the greater part of the attentions of the scientific workers on this pest, and a considerable volume of precise knowledge on these lines has been accumulated by Hardy and his colleagues. From representations made by Dr. J. G. Myers, however, the necessity for more strictly entomological work was realised, work which should be “comparable in precision and in extent with that already amassed by the Committee.” The present paper is an account of a part of the work undertaken with this somewhat ambitious end in view. The studies of which an account is given here were commenced in September 1929, but owing to absence on duty abroad, the real beginning of the work did not occur until March 1930.
