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 Activation and inactivation of fat body glycogen phosphorylase was investigated in ligated abdomens of larval __Manduca sexta__ and in vitro. After maximal activation through __Manduca__ adipokinetic hormone (AKH) or chilling, inactivation of glycogen phosphorylase commenced as soon as
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
Phosphotyrosine-containing proteins are present in the prothoracic glands, muscle, and fat body of Manduca sexta, as determined by immunoprecipitation followed by kinase assay, and by Western blotting. One such protein (M(r) 178,000) can also be immunoprecipitated using antibodies directed against t
