Abstract

A profile of the fatty acid composition in green bolls of cottonseeds at various periods of maturity has been developed. Larval lipids contained 16:0 and 18:1 acids as major constituents except for the first period which in addition contained 18:2 as major components. During the first periods of larval activity TU/TS ratios were over 2:1 whilst in the latter periods were 1:1 or less. The TU/TS ratios in cottonseeds obtained from bolls of successive ages showed some similarity to those in the corresponding larval extracts. Hence lipids of diapaused larvae might be dependent upon lipids of cottonseeds. However, the percentage distribution of individual fatty acids of cottonseeds and larvae at various collection periods was dissimilar.
