A compound having the formula ##STR1296## wherein R and R.sub.1 are independently selected from the group consisting of C.sub.2 -C.sub.10 alkyl and;
- R and R.sub.1 together contain from 12 to 22 carbon atoms;
- R.sub.2 is selected from the group consisting C.sub.1 -C.sub.14 alkyl, C.sub.3 -C.sub.10 alkenyl, and C.sub.3 -C.sub.4 alkynyl;
- and
- R.sub.3 is selected from the group consisting of ##STR1297## wherein R.sub.4 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.22 alkyl, phenyl, and substituted phenyl wherein the substituents are independently selected from the group consisting of halogen, C.sub.1 -C.sub.5 alkyl, C.sub.1 -C.sub.5 alkoxy, nitro, cyano, --N(CH.sub.3).sub.2 and --CF.sub.3, and
- R.sub.5 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, and phenyl.
The lepidoptericidal compositions of claim 21 or 38 or 39 wherein R.sub.3 is ##STR1330## wherein R.sub.4 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.12 alkyl, phenyl and substituted phenyl wherein the substituents are independently selected from the group consisting of halogen, C.sub.1 -C.sub.5 alkyl, C.sub.1 -C.sub.5 alkoxy, nitro, cyano, --N(CH.sub.3).sub.2, and --CF.sub.3 ;
- and R.sub.5 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, and phenyl.
