More than 80% of total lipids of Triatoma infestans are triacylglycerols and only 3.7% and 4.0% are phosphatidyl-ethanolamine and phosphatidylcholine, whereas the diacylglycerols are 0.2%. However in hemolymph that contains 6.8 mg of lipids per ml predominate the phospholipids and there are approximately 22% of diacylglycerols with very little triacylglycerols. Therefore these diacylglycerols may play an important function in fatty acid transport since they incorporate in a few minutes injected 1 14C oleate. The radioactivity is later on transferred to the choline and ethanolamine phospholipids and then to the energy stores represented by the triacylglycerols.
