the effect of two insecticides, imidacloprid and pyriproxyfen, were investigated on some biological parameters of ladybird beetle menochilus sexmaculatus (f.) (coleoptera: coccinellidae) under laboratory condition. theladybird beetle were exposed to insecticides by ingestion of the common pistachio psylla, agonoscena pistaciae burckhardt and lauterer (hemiptera: psyllidae) (prey). for imidaclop...

some oxime ether derivatives of α-ionone (4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-one) have been synthesized. reaction of 4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-ketoxime with various chloro and fluoro aromatic and hetero aromatic compounds gave the corresponding oxime ether derivatives via aromatic nucleophilic substitution (snar). the structures of these compounds were elucida...
