We report on secretion of phospholipase A 2 (PLA 2 ) by in vitro preparations of midguts isolated from tobacco hornworms, Manduca sexta. This enzyme is responsible for hydrolysis of fatty acids from the sn-2 position of phospholipids, a necessary step in fatty acid absorption. The in vitro midgut pr

O n the hypothesis that prostaglandins and other eicosanoids mediate nodulation responses to bacterial infections in insects, we describe an intracellular phospholipase A2 (PLA2) in homogenates prepared from hemocytes collected from the tobacco hornworm, Manduca sexta. PLAz hydrolyzes fatty acids fr
## Abstract Enzyme activities and mitochondrial substrate oxidation were measured in the posterior midguts of tobacco hornworms at different larval stages. A comparison of third, fourth, and fifth instars demonstrated no differences in citrate synthase activity (per gram of midgut), indicating that
