AB - Abstract Techniques for sampling sorghum webwom, Celama sorghiella (Riley), infestations and sorghum midge, Contarinia sorghicola (Coq.), damage in four varieties of grain sorghum were evaluated. No significant correlation occurred between field estimates and standard counts (actual number) of webworm in two tight-headed varieties, Combine Kafir 60 and Martin. Significant correlation did exist between most field and standard webworm counts in case of the open-headed varieties, DeKalb E56a and RS 610. A small range of percentage for rating the degree of midge damage to field grain sorghum had a higher significant correlation to actual grain yields than resulted from a rating method using a larger range.
