Abstract

As a part of our project which aimed to find new growth inhibitors agent’s spodoptera littoralis (Boisd.), several inhibitors structurally relevant to the Fenoxycarb as insect growth regulator, and the naturally transpiring juvenile hormone of insects were chemically designed, prepared and evaluated as anti-proliferative agents. This Epihalohydrins derivatives had previously proved to be an extremely active growth inhibitor against spodoptera littoralis (Boisd.). Insecticidal bioefficacy data showed that that some compounds are very active against spodoptera littoralis (Boisd.) It shows up compounds having naphthalene derivatives 11 and 10 are more active against 2nd instar larvae and 4th instar larvae than another’s of tested compounds.
