Extract

In a field of ground-provisions growing near the Imperial College of Tropical Agriculture at St. Augustine, Trinidad, it was noticed, in November 1928, that the leaves of cassava (Manihot utilissima, L.), which formed a large part of the crop, were attacked by a gall-forming insect. Urich (1915, p. 39) has recorded a gall-midge (Lasioptera sp.) as occurring in Trinidad, with one or two Hymenopterous parasites, and Bequaert (1926, p. 205) states that Felt (1921) reports having received Cecidomyia manihot, Felt, from Trinidad (collected by F. W. Urich).
