Summary

  1. 1.

    Gas-liquid chromatographic analyses of haemolymph lipids inSpodoptera littoralis Boisduval larvae showed the presence of C12:0, C14br, C14:0, C15:0, C15:1, C16:0, C16:1, C17:0, C18:0, C18:1, C18:2, and C18:3 fatty acids.

  2. 2.

    In all studied instars, palmitic acid was the predominant composing about 46–56 per cent of the total, while oleic acid was the major unsaturated fatty acid comprising about 17–19 per cent of all acids.

  3. 3.

    The relative amount of monounsaturated acids was about two and half times more than the polyunsaturated group in the third, fourth, and sixth instars and about four times more in the fifth instar.

  4. 4.

    Relative per cent of linolenic acid was higher in the sixth instar than that of the other studied instars.
