LIPID AND FATTY-ACID ANALYSIS OF UNINFECTED AND GRANULOSIS VIRUS-INFECTED PLODIA-INTERPUNCTELLA LARVAE

A comparative study on the lipid and fatty acid composition of the uni nfected and GV-infected Plodia interpunctella larvae was performed. Hi gher levels of free fatty acids were found in GV-infected larvae compa red to those of the uninfected larvae, while the latter had more triac ylglycerol compared to the former. The known identified phospholipids were fewer in the GV-infected larvae compared to those in the uninfect ed larvae. However, an unidentified phospholipid was found to be appro ximately two times higher in GV-infected larvae. The total lipid of bo th larvae had palmitic, oleic, and linoleic as the major fatty acids. The fatty acid composition of the GV-infected larval phospholipid diff ered considerably compared to that of the uninfected larvae, in that t he ratio of unsaturated fatty acid to saturated fatty acid was 3.5 tim es less in the GV-infected larvae.
