Notes on Helopeltis sanguineus, Popp., on Cotton in Nigeria
Published online by Cambridge University Press: 10 July 2009
Extract
In 1925, the writer (2) described some experiments that demonstrated the rôle of Helopeltis as a pest of cotton at Ibadan, Nigeria. Evidence was obtained that attack was greater on the improved indigenous Ishan (Gossypium barbadense, formerly described as G. vitifolium) than on either American Allen (G. hirsutum) or the ordinary native cotton (G. peruvianum).
