Abstract: Insecticidally and acaricidally active novel compounds of the formula ##STR1## in which A is --CF.sub.2 --CF.sub.2 --, --CF.sub.2 --CHF-- or --CF.sub.2 --CFCl--,X is oxygen or sulphur,R.sup.1, R.sup.2 and R.sup.3 each independently is hydrogen, halogen or alkyl,R.sup.4 and R.sup.5 each independently is hydrogen, halogen, alkyl or halogenoalkyl, andR.sup.6 is hydrogen, halogen or alkyl.The benzodioxene intermediates therefor are also new.

Abstract: Compounds of the formula ##STR1## in which R.sup.1 is hydrogen, halogen or alkyl,R.sup.2 is halogen, alkyl or alkylthio,X is oxygen or sulphur, andY is hydrogen, halogen, alkyl or halogenoalkyl,which possess pesticidal activity.

Abstract: Pesticidally active 2,2-dimethyl-3-(2-halogeno-vinyl)-cyclopropanecarboxylic acid esters of the formula ##STR1## in which R.sup.1 and R.sup.2 are identical or different and represent alkyl or halogenoalkyl,R.sup.3 represents alkyl or the grouping --(CH.sub.2)--.sub.n R.sup.4,in whichn represent 0 or 1 andR.sup.4 represents halogenoalkyl, optionally substituted aryl or the grouping --XR.sup.5,in whichX represents oxygen or sulphur andR.sup.5 represents alkyl, halogenoalkyl, optionally substituted aryl or optionally substituted aralkyl,Hal represents fluorine, chlorine or bromine andR represents an alcohol radical which can be used in the case of pyrethroids.Intermediates carrying an acid, acid chloride or alkyl ester group in place of --COOR are also new.

Abstract: The present invention relates to new substituted hydroxy-malonic acid amide-thioamides of the formula (I) ##STR1## in which R represents optionally substituted alkyl, optionally substituted alkenyl, optionally substituted cycloalkyl, optionally substituted aryl or optionally substituted heteroaryl,and a process for their preparation and their use as agents for combating pests, in particular insecticides and acaricides.

Abstract: The present invention relates to combating pests with five-membered nitrogen-containing heterocyclic compounds of the formula (I) ##STR1## in which R.sup.1, R.sup.2, R.sup.3, X and Y have the meaning given in the description. Many of the compounds are new.

Abstract: 3-(Pyrimidin-5-yl-oxy-phenyl)-1-benzoyl-(thio)-ureas of the formula ##STR1## in which R represents hydrogen, alkyl, cycloalkyl, halogenoalkyl or optionally substituted aryl,R.sup.1 represents hydrogen, nitro, halogen, alkyl or alkylthio,R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are indentical or different and represent hydrogen or halogen,R.sup.6 and R.sup.7 are identical or different and represent hydrogen, halogen or alkyl andX represents oxygen or sulphurwhich possess arthropodicidal activity. Novel intermediates are also shown.

Abstract: Pyrimidin-5-yl-(thio)phosphoric acid ester-amides of the formula ##STR1## in which X is oxygen or sulphur,R is hydrogen, alkyl, aryl or cycloalkyl,R.sup.3 is alkyl, halogenoalkyl, cyanoalkyl, mono- or di-alkylamino, optionally substituted aryl, or ##STR2## R.sup.1, R.sup.2, R.sup.4, R.sup.6 and R.sup.7 each independently is alkyl, andR.sup.5 is alkyl or optionally substituted aryl which possess pesticidal activity.

Abstract: The invention relates to new O-(pyrazol-4-yl) N-(.alpha.-cyanoalkylsulphenyl)-carbamates of the general formula (I) ##STR1## in which R.sup.1 represents alkyl or cycloalkyl,R.sup.2 represents alkyl andR.sup.3 and R.sup.4 each represent alkyl or together represent an alkylene radical linked in two places,which can be used as agents for combating pests.
