Juvenile hormone acid methyltransferase activity in imaginal discs of Manduca sexta prepupae. It was first discovered in immune-challenged pupae of "Hyalophora cecropia" and "Manduca sexta". The substrate specificity of juvenile hormone esterase from Manduca sexta haemolymph. In studies with "Manduca sexta", moths have dynamic flight sensory abilities due to their antennae. Juvenile hormone-specific esterases in the haemolymph of the tobacco hornworm, Manduca sexta. The haemolyph juvenile hormone esterase of Manduca sexta (L.)-inhibition and regulation. Tomato hornworms are closely related to (and sometimes confused with) the tobacco hornworm "Manduca sexta". In the crepuscular hawk moth ("Manduca sexta"), antennae aid in flight stabilization. The polydnavirus will severely interfere with development of the host, "Manduca sexta".
