This invention relates to insecticidal compositions containing N'-substituted-N,N'-disubstitutedhydrazines, methods of using such compositions and N'-substituted-N, N'-disubstitutedhydrazines. Specifically, the invention relates to insect growth regulating compositions, and methods of using such compositions, which include compounds having a nucleus of the formula ##STR1## where A', B', D and J are independently any atom or group of atoms; where E is a tertiary carbon containing organic radical, a haloalkyl having a total of at least four carbon and halogen atoms but not more than six halogen atoms, or a non-tertiary carbon containing non-haloalkyl organic or organometallic radical having at least five atoms other than hydrogen, oxygen and halogen, and is attached to the nitrogen shown in the formula by a carbon-to-nitrogen single bond; where one G.sub.1 is C, N, O and S, and both G.sub.2 's and the other G.sub.1 are carbon; or one G.sub.2 is S or P, and both G.sub.1 's and the other G.sub.2 are carbon; where the bonds shown as - - - are independently single or double bonds; where the A'-?-G.sub.1 and G.sub.1 -?-B' bonds are independently single bond, double bonds or aromatic bonds; where organic radical is a radical comprising at least one carbon atom, but no metal atoms; where organometallic radical is a radical containing a carbon-to-metal bond; or an agronomically acceptable salt thereof; and with the provisos discussed infra.
