Abstract:
A primitive cotton (Gossypium hirsutum L.) accession, V-64, from the Caribbean Islands was bioassayed for antibiosis against pests of this crop in comparison with the commercial strains Acala SJ-2 and Pima S-5. V-64 reduced weight gain and leaf consumption of Spodoptera littoralis and Helicoverpa armigera, and significantly reduced oviposition of Bemisia tabaci. The leaf pigment glands in V-64 were larger and more abundant than in the commercial strains, and the feeding of H. armigera on these glands was avoided, indicating that the glands probably constituted the major resistance character in V-64. © 1991, Springer Science + Business Media B.V..
