Abstract
Novel pesticidal compounds of the formula: ##SPC1## Wherein R.sub.1 and R.sub.2 are the same or different and are selected from the group consisting of lower alkyl of from 1 to 4 carbon atoms; R.sub.3 and R.sub.4 are the same or different and are selected from the group consisting of hydrogen, halogen, and lower alkyl of from 1 to 4 carbon atoms, n = 1 or 2 provided that when n is 2 then R.sub.1 and R.sub.2 are the same as R.sub.3 and R.sub.4 are the same. 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.
