31. Growth of the male accessory gland in adult locusts : Roles of juvenile hormone , JH esterase, and JH binding proteins. 32. This large insect had enough juvenile hormone in its abdomen to permit extraction of detectable JH from a single abdomen. 33. Compared with vertebrate, insects and crustaceans possess a number of structurally unusual hormones such as the juvenile hormone , a sesquiterpenoid. 34. "' Methoprene "'is a juvenile hormone ( JH ) analog which acts as a growth regulator when used as an insecticide. 35. The vitellogenin expression is part of a regulatory feedback loop that enables vitellogenin and juvenile hormone to mutually suppress each other. 36. The degradative metabolism of juvenoids by insects, in : Gilbert, L . I . ( Ed . ), The Juvenile Hormones . 37. Elevated juvenile hormone levels have a negative effect on larval growth regardless of whether larvae forage by begging or by self-feeding. 38. In addition, it is induced by treatment of insects with either natural juvenile hormone , with JH I being the most potent inducer. 39. Queen bees can control oogenesis in worker bees by suppressing juvenile hormone ( JH ) in the workers, which regulates egg development. 40. Certain species of crustaceans have been shown to produce and secrete methyl farnesoate, which is juvenile hormone III lacking the epoxide group.
