Abstract
The insecticidal activity of six lately synthesized carbamate derivatives of furfural oxime N-methylcarbamate (I), 5-methyljural oxime N-methylcarbamate (II), methyl p-(methylcarbamoyl) oxybenzoate (IV), ethyl p-(methylcarbamoyl) oxybenzoat(V), n-propyl p-(methyl carbamoyl)oxybenzoate(VI) and n-butyl p-(methyl carbamoyl)oxybenzoate examined using o.2w/v% acetone solutions of each compound. Among them, alkyl p-(methyl carbamoyl) oxybenzontes exerted slightly insecticidal effects on Sogata furcifera H$_{ORVATH}$, Delphacodes stria striatella FALLEN, wherease no significant effects were observed on Mil-aparvata Iugens Stal, Inazuma dorsolis Moischiulsky, and Naphotettix apicalis cincticeps U$_{HLER}$.
