- 2. A compound of claim 1 wherein X is fluorine.
- 3. A compound of claim 1 wherein the cyclopropane copula has (1R, cis) structure.
- 4. A compound of claim 1 wherein the double bond has (E) geometry.
- 5. A compound of claim 1 which is 2,3,5,6-tetrafluorobenzyl [1R-[1.alpha.,3.alpha.(E)]]-3-(2-cyano-2-fluoro-ethenyl)-2,2-dimethyl-cyclopropanecarboxylate.
- 6. An insecticidal composition comprising an insecticidally effective amount of at least one compound of claim 1 and an insert carrier.
- 7. A composition of claim 6 wherein X is fluorine.
- 8. A composition of claim 6 wherein the cyclopropane copula has (1R,cis) structure.
