The 1,4-diaryl-1-cyclopropyl-4-substituted butane pesticides of the following formula are effective as insecticides and acaricides: ##STR1## in which X and Y are independently hydrogen, halogen, alkyl, alkoxy, cycloalkylalkoxy, alkylcarbonyl, alkoxycarbonyl, haloalkyl, haloalkoxy, alkylthio, haloalkylthio, alkylsulfinyl, alkylsulfonyl, trialkylamino, nitro, or cyano; or X and Y together are --OCH.sub.2 O-- or --OCF.sub.2 O-- bridging the 2-3 or 3-4 positions of the phenyl ring; Ar is 3-phenoxyphenyl, 4-fluoro-3-phenoxyphenyl, 6-phenoxypyridin-2-yl, or 2-methyl(1,1'-biphenyl)-3-yl;

1,4-diaryl-1-cyclopropyl-4-substituted butanes as insecticides and

Ethynylbenzothiophene compounds of the following formula are effective as pesticides. ##STR1## wherein R is selected from ##STR2## R.sup.1 is selected from hydrogen, halogen, lower alkyl, lower haloalkyl, and phenylethynyl;

Ethynylbenzothiophene pesticides

Compounds of the formula ##STR1## in which Ar is substituted or unsubstituted phenyl, naphthyl, or thienyl; and Ar.sup.1 is 3-phenoxyphenyl, 4-fluoro-3-phenoxyphenyl, 2-methyl[1-1'-biphenyl]-3-yl, or 6-phenoxy-2-pyridyl, exhibit pyrethroid-like insecticidal and acaricidal activity and are relatively nontoxic to fish.

Insecticidal cyclopropyl di(aryl) 2-butenes

Compounds of the formula ##STR1## in which Ar is substituted or unsubstituted phenyl, naphthyl, or thienyl; Z is oxygen, sulfur, or methylene; and Ar' is 2-methyl[1,1'-biphenyl]-3-yl, 3-phenoxyphenyl, 4-fluoro-3-phenoxyphenyl, or 6-phenoxy-2-pyridyl exhibit pyrethroid-like insecticidal and acaricidal activity and are relatively harmless to aquatic fauna.
