Compounds are prepared which correspond to the formula ##STR1## wherein each X independently represents chloro, fluoro or bromo; X' represents hydrogen, methyl, chloro, fluoro or bromo; G represents oxygen or sulfur; Z represents oxygen, sulfur, sulfinyl or sulfonyl, with the proviso that Z is attached to the pyridine ring in only the 2 or 4 ring position; D represents cyano, nitro, trifluoromethyl, loweralkyl, loweralkoxy, loweralkylsulfonyl, loweralkylthio, or the radical ##STR2## R represents loweralkoxy, loweralkylamino or diloweralkylamino; R' represents R or phenyl; m represents an integer of from 0 to 4; n represents 0 or 1 and the sum of m + n represents an integer of from 0 to 4. The compounds have been found to be effective insect control agents.
