Abstract
Novel pesticidal compounds of the formula: ##STR1## wherein R.sub.1 is lower alkyl of from 1 to 4 carbon atoms; R.sub.2 is hydrogen, halogen or lower alkyl of from 1 to 4 carbon atoms; R.sub.3 and R.sub.4 are the same or different and are hydrogen, alkyl of 1 to 8 carbon atoms, inclusive; haloalkyl, arylalkyl and ##STR2## WHEREIN ALKYL IS FROM 1 TO 4 CARBON ATOMS, CYCLOALKYL OF FROM 3 TO 6 CARBON ATOMS, ARYL AND R.sub.3 and R.sub.4 taken together are a member selected from the group piperidine, morpholine, pyrazole, tribromopyrazole, N-methylpiperazine, pyrrole, pyrrolidine, pyrrolidone. The compounds are combined with carriers to prepare compositions and are useful in controlling insect pests either as an insecticide or behavioral modifier and are particularly effective as miticides.
