Application under field conditions of the juvenoid ethyl 11-chloro-3,7,11-trimethyldodec-2-trans-enoate to the caterpillars of Tortrix viridana induced development of intermediate forms between larva and pupa and between pupa and adult and increased

The paper describes activities of 31 representative juvenoids selected out of 200 compounds assayed on eggs, larvae, prepupae, and pupae. Affected eggs ceased to develop or produced malformed embryos, the larvae pupated with a delay or produced larva

The freshly ecdysed pupae are the most sensitive stage of L. decemlineata to juvenoids. They respond to 0.00002 μg/spec. of ethyl 3,7, 11-trimethyl-2,4-dodecadienoate and to ten times higher doses of three other compounds. Juvenoids impede the pupal

Acetone solutions containing 0.01% or more of juvenoids inhibit hatching when administered to freshly laid eggs of Spodoptera littoralis and Mamestra brassicae. Application of 1–100 μg of juvenoids to penultimate instar larvae of these species ind

Larvae of Syrphus corollae were treated with 30 selected juvenoids. One microgramme of the most active compound, the isopropyl 11-methoxy-3,7, 11-trimethyl-dodeca-2,4-die-noate, was required to cause incomplete rotation of male genitalia or failure o

Application of juvenoids to feeding last instar larvae of Galleria mellonella affects the onset of moult. The effect seems to be due to a direct inhibition of prothoracic glands and to modification of the prothoracicotropic brain activity. This doubl

Cul-1 protein is part of the ubiquitin ligase complex that is conserved from yeast to humans. This complex specifically marks cell-cycle regulators for their subsequent destruction. Two null mutations of the cul-1 gene are known, in budding yeast and
