Claims (4)

REVENDICATIONS 1. Produit insecticide et antiparasitaire à base de Pyrethrines, pyréthrinoïdes et/ou roténones naturelles ou de synthèse, caractérisé en ce que sa formulation comprend, en plus, du diméthylformamide.1. Insecticide and pest control product based on natural or synthetic pyrethrins, pyrethroids and/or rotenones, characterized in that its formulation additionally comprises dimethylformamide. 2. Utilisation du produit selon la revendication 1 dans la lutte contre les insectes et parasites.2. Use of the product according to claim 1 in the fight against insects and parasites. 3. Utilisation selon la revendication 2 dans la lutte contre les poux, moyennant une teneur en diméthylformamide pour moitié environ du produit.3. Use according to claim 2 in the fight against lice, with a dimethylformamide content for about half of the product. 4. Utilisation selon la revendication 2 dans la lutte contre les insectes et parasites fréquentant les étables, moyennant une teneur en diméthylformamide à concurrence de 90% environ.4. Use according to claim 2 in the fight against insects and parasites frequenting stables, with a dimethylformamide content of approximately 90%. La présente invention concerne un produit insecticide et antiparasitaire à base de pyréthrines, pyréthrinoïdes et roténones naturelles et de synthèse, et son utilisation.The present invention relates to an insecticide and antiparasitic product based on natural and synthetic pyrethrins, pyrethroids and rotenones, and its use. Les pyréthrines, pyréthrinoïdes et roténones naturelles ou de synthèse ont l'avantage d'être actifs dans des formulations devant éliminer des insectes, reptiles, batraciens, mollusques, crustacés et poissons, etc., c'est-à-dire tout animal vivant à sang froid. Ils s'emploient généralement à des doses de 5 à 2%a avec des synergisants.Natural or synthetic pyrethrins, pyrethroids and rotenones have the advantage of being active in formulations intended to eliminate insects, reptiles, batrachians, molluscs, crustaceans and fish, etc., i.e. any animal living in cold blood. They are generally used in doses of 5 to 2%a with synergists. Les pyréthrines et pyréthrinoïdes ont l'inconvénient de ne paralyser les insectes que pour une période plus ou moins courte pouvant varier de quelques minutes à plusieurs heures. Toutefois, quand la paralysie excède 6 h, l'insecte meurt.Pyrethrins and pyrethroids have the disadvantage of only paralyzing insects for a more or less short period which can vary from a few minutes to several hours. However, when the paralysis exceeds 6 h, the insect dies. On remédie à cet inconvénient de paralysie simplement momentanée en introduisant dans la formulation d'autres insecticides naturels ou de synthèse, tels que par exemple des organochlorés, des organophosphorés ou des alcaloïdes dans des proportions variables. Toutefois, il en résulte que la qualité première des pyréthrines et pyréthrinoïdes, qui est la très faible toxicité des formulations pour les espèces à sang chaud, se trouve atténuée par l'adjonction de matières toxiques. Donc, la qualité de produit non polluant des pyréthrines et pyréthrinoïdes se trouve affectée.This disadvantage of simply momentary paralysis is remedied by introducing into the formulation other natural or synthetic insecticides, such as for example organochlorines, organophosphates or alkaloids in variable proportions. However, the result is that the first quality of pyrethrins and pyrethroids, which is the very low toxicity of the formulations for warm-blooded species, is attenuated by the addition of toxic materials. Therefore, the non-polluting product quality of pyrethrins and pyrethroids is affected. Un objet de la présente invention consiste à remédier à l'inconvénient mentionné ci-dessus, sans altérer la qualité de produit non 5 polluant des pyréthrines, pyréthrinoïdes et roténones naturelles ou de synthèse.An object of the present invention consists in remedying the drawback mentioned above, without altering the quality of the non-polluting product of the natural or synthetic pyrethrins, pyrethroids and rotenones. Le produit insecticide et antiparasitaire selon l'invention, à base de pyréthrines, pyréthrinoïdes et/ou roténones naturelles ou de synthèse, est caractérisé en ce que sa formulation comprend, en plus, io du diméthylformamide.The insecticide and antiparasitic product according to the invention, based on natural or synthetic pyrethrins, pyrethroids and/or rotenones, is characterized in that its formulation additionally comprises dimethylformamide. En effet, il a été constaté expérimentalement que l'adjonction de diméthylformamide aux pyréthrines et pyréthrinoïdes augmente considérablement la mortalité des insectes et améliore la rémanence de la formulation. Or, il a été également constaté qu'une formulation 15 à base de pyréthrines ou pyréthrinoïdes ou roténones contenant du diméthylformamide conserve la qualité de produit «inoffensif aux doses usuelles d'emploi» envers les espèces à sang chaud.Indeed, it has been observed experimentally that the addition of dimethylformamide to pyrethrins and pyrethroids considerably increases the mortality of insects and improves the persistence of the formulation. However, it has also been observed that a formulation based on pyrethrins or pyrethroids or rotenones containing dimethylformamide retains the quality of product “harmless at the usual doses of use” towards warm-blooded species. En pratique, la mortalité des insectes est augmentée par le fait que les molécules de diméthylformamide sont véhiculées avec les molécules d'insecticides dans le sang de l'insecte et, dès que les molécules de diméthylformamide sont dans le muscle cardiaque, elles bloquent ce dernier. Ainsi, l'action conjuguée de l'insecticide et du diméthylformamide accroît la rapidité de l'effet de knock down et l'insecte est plus rapidement terrassé.In practice, insect mortality is increased by the fact that the molecules of dimethylformamide are transported with the molecules of insecticides in the blood of the insect and, as soon as the molecules of dimethylformamide are in the heart muscle, they block the latter. . Thus, the combined action of the insecticide and the dimethylformamide increases the rapidity of the knock down effect and the insect is struck down more quickly. Les expériences menées ont fait apparaître que l'utilisation d'un produit ayant pareille composition, est indiquée dans la lutte contre les insectes et parasites, notamment contre ceux qui fréquentent les étables, et contre les poux. Dans la lutte contre les poux, la formulation comprendra du diméthylformamide pour moitié environ. Dans la lutte contre les insectes et parasites fréquentant les étables, elle en comprendra à concurrence de 90% environ.The experiments carried out have shown that the use of a product having such a composition is indicated in the fight against insects and parasites, in particular against those which frequent barns, and against lice. In the fight against lice, the formulation will include dimethylformamide for about half. In the fight against insects and parasites frequenting barns, it will include about 90% of them. Le diméthylformamide présente l'avantage de ne pas augmenter la très faible toxicité des pyréthrines, pyréthrinoïdes et roténones; le produit ainsi obtenu est donc efficace sans être nocif. De plus, le diméthylformamide augmente la solubilité des pyréthrines et pyréthrinoïdes dans de nombreux solvants, ce qui permet de diminuer la proportion de ces derniers dans le fluide véhiculant l'insecticide en vue de son utilisation en vaporisation, etc.Dimethylformamide has the advantage of not increasing the very low toxicity of pyrethrins, pyrethroids and rotenones; the product thus obtained is therefore effective without being harmful. In addition, dimethylformamide increases the solubility of pyrethrins and pyrethroids in many solvents, which makes it possible to reduce the proportion of the latter in the fluid carrying the insecticide with a view to its use in vaporization, etc. 2525 3030 RR
