الملخص EN

The present research is conduct to synthesize and evaluate the pesticidal efficacy of 2-(benzo[d]thiazole-2-yl)-3,A3-bis(methylthio) acrylonitrile and their new derivatives against cotton leafworm Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) that were obtained by reaction of this compound with different aromatic and heterocyclic amines.

2-(Benzo[d]thiazole-2-yl)-3, 3-bis (methylthio) acrylonitrile (2) was consider as promising compound.

So that it was formulated and evaluated against the 2nd instar larvae of the cotton leafworm S.

littoralis .

It was found thatA the latter compound has good efficacy as obtained from its LC50 compared with that of the other derivatives.
