INSECTICIDAL, MITICIDAL, AND OVICIDAL ACTIVITY OF 5,6-DIHYDRO-4H-1,3,4-OXADIAZINES

Dihydrooxadiazines, conformationally restricte analogs of octopamine, were toxic to eggs of twospotted spider mites, Tetranychus urticae (Ko ch); to eggs of tobacco budworms, Helicoverpa virescens (F.); and to a dult rice delphacids, Sogatodes orizicola (Muir). The effects of dihyd rooxadiazines on reproduction of T. urticae included inhibition of bot h oviposition and egg hatch.
