The Binding of Juvenile Hormone to Larval Epidermis: Influence of Carrier Protein from the Hemolymph of Plodia interpunctella

  • Chapter
The Juvenile Hormones

Abstract

The role of juvenile hormone (JH) in growth and development of insects has been discussed in several recent reviews (Menn and Beroza, 1972; Burdette, 1974; Sláma et al., 1974). The hormone is secreted by the corpora allata and is transported by the hemolymph to target tissues. Lipoproteins and low molecular weight proteins in the hemolymph have been implicated as carriers for JH (Trautmann, 1972; Whitmore and Gilbert, 1972; Emmerich and Hartmann, 1973; Kramer et al., 1974a; Ferkovich et al., 1975). The low molecular weight proteins which bind JH and have been isolated from both Manduca sexta (Sanburg et al., 1975a,b) and Plodia interpunctella * protect JH against nonspecific esterases in fourth- and early fifth-instar larvae. JH specific esterases that degrade the protein-bound JH also appear in the hemolymph during the late fifth instar and may provide a mechanism for removing JH from the hemolymph to permit metamorphosis.
