Abstract: 1. An insecticide composition comprising: a) between 0.001 and 5 %, preferably between 0.05 and 1 %, more preferably between 0.05 and 0.5% of a compound of formula I: in which: R1 is a halo atom or a CN group, or a methyl group, or a CH3CO group; R2 is S(O)nR3; R3 is C1-C6 alkyl or haloalkyl; R4 is a hydrogen or halo atom, or a NR5R6 radical, S(O)mR7, C(O)R7 or C(O)O-R7, C1-C6 alkyl, haloalkyl containing 1-6 carbon atoms or OR8; or a -N=C(R9)(R10) radical; R5 and R6 are independently a hydrogen atom or an alkyl C1-C6 radical, haloalkyl, containing 1-6 carbon atoms, C (O) alkyl C1-C6, S(O)rrCF3; or R5 and R6 can together form divalent alkylene radical which can be interrupted by one or two divalent hetero atoms such as oxygen and sulfur; R7 is an alkyl C1-C6 radical or haloalkyl, containing 1-6 carbon atoms; R8 is an alkyl C1-C6 radical, haloalkyl, containing 1-6 carbon atoms or a hydrogen atom; R9 is an alkyl C1-C6 radical or a hydrogen atom; R10 is a phenyl radical or heteroaryl optionally substituted by one or a plurality of halo atoms or by groups such as OH, -O-alkyl C1-C6, -S-alkyl C1-C6, cyano, or alkyl C1-C6; X is a trivalent nitrogen or a C1-C12 radical, in which three other valences of a carbon atom constitute a portion of an aromatic cycle; R1 and R12 are independently a hydrogen or halo atom; R13 is a halo atom or a haloalkyl radical, haloalkoxy, containing 1-6 carbon atoms, S (O)qCF3 or SF5; m, n, q and r are independently integers 0, 1 or 2; provided that when R1 is methyl than R3 haloalkyl, R4 is NH2, R11 is Cl, R13 is CF3, and X is N; b) between 0.05 to 10%, preferably between 0.1 to 5 % one (or a plurality of) agent(s) retaining moisture, preferably an agent retaining moisture of organic nature; and c) between 40 to 99%, preferably between 50 to 98% (and more preferably between 70 to 97%) vegetable flour. 2. The insecticide composition according to claim 1, characterized in that the flour is produced by milling cereals such as wheat, barley, rye, triticale, oats, and also rice, sorghum, soy and maize. 3. The insecticide compositions according to claim 1 and 2, characterized in that the flour is maize flour. 4. The insecticide composition according to any one of claims 1 to 3, characterized in that hydrophilic macromolecular derivatives of vegetable origin, in particular, hydrophilic derivatives of cellulose and more definite cellulose are used as a water-retentive agent of organic nature. 5. The insecticide composition according to any one of claims 1 to 4, characterized in that the composition contains between 3 to 30%, preferably between 4 to 20% of sugar. 6. The insecticide composition according to any one of claims 1 to 4, characterized in that the sugar is selected, in particular, from mono-, oligo- or polyorganosaccharides, and more definitely from sucrose, lactose, fructose, dextrose, glucose or also from molasses or honey. 7. The insecticide composition according to any one of claims 1 to 6, characterized in that comprises a conservative agent formed during flour degradation, such as sodium benzoate, 1,2 benzisothiazoline-3-one, benzoic acid, p-hydroxybenzoic acid, esters thereof, and salts thereof with alkali or alkali-earth metals, in particular, sodium salt, 2-phenylphenol, and salts thereof with alkali or alkali-earth metals, in particular, sodium salt, paranitrophenol. 8. The insecticide composition according to any one of claims 1 to 7, characterized in that comprises other additives, such as dying agents or attractive agents for pests or repulsive agents for birds and animals which are useful or to be protected, and/or other additives used for ready formulations such as gluing, agglomerating, causing appetite, agglutinating, gel-forming, bloating, antiadhesive and other additives. 9. The insecticide composition according to any one of claims 1 to 8, characterized in that the compound of formula I is 5-amino-3-cyano-1-[2,6-dichloro-4-(trifluoromethyl) phenyl]-4-[(trifluoromethyl) sulfinyl]-1H-pyrazole. 10. The insecticide composition according to any one of claims 1 to 9, characterized in that the ready formulations are in the form of granules between 0.1 mm to 3 mm, preferably between 0.5 mm to 4 mm, said granules are preferably insoluble in water. 11. A method for fighting insects, characterized in that an effective amount of the composition according to any one of claims 1 to 10 in the form of granules between 0.2 mm to 2 cm in size is applied on soil or in soil (preferably in soil) in a zone to be cultivated. 12. The method according to claim 11, characterized in that the compound of formula I is used for crop protection. 13. The method according to claim 11 or 12, characterized in that cereals are protected, preferably maize or beet, or sun flower, or potato, or rape. 14. The method according to any one of claims 11 to 13, characterized in that an effective amount of one of compositions is used for fighting insects, in particular, against click beetles. 15. The method according to any one of claims 12 to 14, characterized in that an effective amount of the composition corresponds to the dose of the composition of formula I, which is between 1 to 50g/ha, preferably between 3 to 40 g/ha. 16. The method for fighting insects, comprising applying on or in soil the composition as defined in one claims 1 to 10, comprising a dose which is not lethal in contact, but lethal in ingestion. 17. The method according to claim 16 used against click beetles.
