title: Fatty acid composition of whole bodies, specific tissues and cell lines of two lepidopteran insects.
abstract: We detail the fatty acid compositions of last larval instars of two lepidopterans, Spodoptera frugiperda and Trichoplusia ni, two tissues from T. ni, a cell line derived from each species and the respective larval and cell culture media. Larval whole-body and specific tissue fatty acid profiles exhibited the major features commonly found in previous lepidopteran analyses, whereas the cell-line fatty acid compositions were substantially different from the compositions of both their growth media and larvae of their respective species. It appears that these cell-line patterns result from increased monoene biosynthesis in response to low levels of exogenous polyunsaturated fatty acids, a commonly observed essential fatty acid deficiency symptom in whole animals.
