Abstract: The present invention relates to immediately acting pest control compositions based on cyclic polysiloxanes, which can be employed without a residue and without a lasting action.

Abstract: An anti-fouling composition comprising a carrier, and a binder, the improvement which comprises an effective amount of at least one insecticide. The composition is applied to the surfaces of articles which come into contact with seawater or brackish water, especially wood. Other conventional anti-fouling agents may also be present.

Abstract: The present invention relates to the use of cyclic depsipeptides having 18 ring atoms of the general formula (I) ##STR1## in which R.sup.1 to R.sup.6 have the meaning given in the description, and to their optical isomers and racemates, in medicine and veterinary medicine for combating endoparasites, to their preparation, and to new cyclic depsipeptides having 18 ring atoms.

Abstract: New cyclic depsipeptides having 18 ring atoms, of the general formula (I) ##STR1## in which R represents hydrogen, straight-chain or branched or cyclic alkyl having up to 8 carbon atoms,and their optical isomers and racemates,and their use for combating endoparasites in the field of medicine and veterinary medicine.

Abstract: Insecticidally active substituted heteroaryl phenyl ethers of the formula ##STR1## in which Het represents an optionally substituted heteroaromatic radical,X represents O, S, --CH.sub.2 --, --O--CH.sub.2 --, --S--CH.sub.2 --, --CH.sub.2 --O--, ##STR2## Y represents O, --O--CH.sub.2 -- or S, Z represents an optionally substituted aromatic or heteroaromatic radical;m represents integers from 1-4n represents 0, 1, 2, 3, 4O represents 0, 1, 2, 3, 4, provided than n and o do not simultaneously represent 0p represents integers from 1-4,R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 independently of one another represent hydrogen, C.sub.1 -C.sub.6 -alkyl which is optionally substituted; two radicals adjacent to one another can also, together with the C atoms to which they are bonded, form a saturated carbocyclic 5- or 6-ring,R.sup.1 represents identical or different radicals hydrogen, halogen, CN, C.sub.1-4 -alkyl, 1-5-halogeno-C.sub.1-4 -alkyl, C.sub.1-4 -alkoxy, C.sub.1-4 -alkylthio, 1-5-halogeno-C.sub.

Abstract: The present invention relates to the use of substituted alkoxydiphenyl ethers or alkoxydiphenylmethanes of the general formula I ##STR1## in which R.sup.1 represents hydrogen, halogen, alkyl, alkoxy, alkylthio, halogenoalkyl, halogenoalkoxy, halogenoalkylthio, dioxalkylene, dioxyhalogenoalkylene, CN, NO.sub.2, alkenyl, alkinyl, alkoxyalkyl, alkoxyalkoxy or hydroxyalkoxy,R.sup.2 represents the radicals indicated for R.sup.1,R.sup.3 represents the radicals indicated for R.sup.1,R.sup.4 represents hydrogen, alkyl, halogenoalkyl or halogen,R.sup.5 represents the radicals indicated for R.sup.4,Het represents optionally substituted heteroaryl which is not linked to the remaining radical via the hetero atom,X, Y independently of one another represent --O-- or --S--Z represents --O--, --S--, --CH.sub.2 --, --CHCH.sub.3 -- or --C(CH.sub.3).sub.2 --,m and n independently of one another represent 0, 1, 2 or 3 but their total is equal to, or more than, 2are exceedingly suitable for controlling fleas.
