Abstract: The invention describes a biodegradable device with a slow-release of volatile products having an attractant action with respect to insects, which can be applied to a wide range of crops.

Abstract: Amides of pyrazolecarboxy acids having the general formula (I): ##STR1## exhibiting a high insecticidal and acaricidal activity.

Abstract: 5-pyrazolecarboxylic acid amide-based insecticide and acaricide compounds of general formula (I): ##STR1## in which: R.sub.1 represents a hydrogen atom, a linear or branched C.sub.1 -C.sub.4 alkyl group or a benzyl group;R.sub.2 represents a hydrogen atom or a linear or branched C.sub.1 -C.sub.4 alkyl group;R.sub.x represents a hydrogen atom, a halogen atom such as chlorine, fluorine or bromine, or a linear or branched C.sub.1 -C.sub.4 alkyl or haloalkyl group; or R.sub.2 and R.sub.x together represent an RHC--(CH.sub.2).sub.n --CH.sub.2 group in which R represents a hydrogen atom or a C.sub.1 -C.sub.3 alkyl group and n is a whole number between 1 and 2;R.sub.3, R.sub.4, R.sub.5 represent, each independently, a hydrogen atom or linear or branched C.sub.1 -C.sub.4 alkyl group;X.sub.1, X.sub.2, X.sub.3 and X.sub.4 represent, each independently, a hydrogen atom or a halogen atom such as chlorine, fluorine or bromine;R.sub.y represents a linear or branched C.sub.3 -C.sub.

Abstract: There are described 1-phenoxy(phenylthio)-4-aryl-alkynyloxy-benzene derivatives endowed with a juvenile hormonic activity towards insects and with an acaricide activity. The use of these compounds for controlling insects infestations in both the agrarian and civil field and the processes for preparing said compounds are described too.

Abstract: There are described compounds of formula: ##STR1## in which X (or X')=H, F, Cl and X' (or X)=F, Cl; ##STR2## with R.sup.2 =H, Cl, Br, F an optionally halogen-substituted alkyl C.sub.1 -C.sub.3 ;R.sup.3 =halogen, an optionally halogen-substituted alkyl C.sub.1 -C.sub.3 ;R.sup.4 =H or R.sup.3 ;R.sup.1 =H, halogen, an optionally halogen-substituted alkyl C.sub.1 -C.sub.3, OCH.sub.3, SCH.sub.3, OCF.sub.3 ;n=an integer from 1 to 4.The compounds of formula I are endowed with a high insecticide activity which is mainly exerted against insects' larvae and eggs.

Abstract: There are described compounds of formula: ##STR1## in which one of R and R.sup.1 is F or Cl and the other is H, F or Cl;X is a 1,4-phenylene or pyridyl bound in positions 2 and 5, optionally substituted;Y is a phenyl, 2- or 3-pyridyl, optionally substituted.The compounds of formula I are endowed with a high insecticide activity which is mainly directed against insect larvae and eggs.
