The hormonal regulation of life processes in insects (2.) The anti-juvenile hormones (1.)

Those compounds that decrease either the level or activity of natural endogenous juvenile hormones in insects are called anti-juvenile hormones (AJH). The possible effects of anti-juvenile hormones are manifold: they may inhibit special enzymes or the bindings of juvenile hormones to receptors and transport proteins or may cause the destruction of corpora allata, the sources of juvenile hormones. The most obvious possibility to elicit an anti-juvenile hormone effect lies in the inhibition of enzymes participating in the biosynthesis of juvenile hormones
