Abstract

Improved rodenticide bait consisting of an edible support to which an active rodenticide substance has been added, characterised in that it also comprises a synthetic pear aroma. Application: rat destruction.

Description

L'invention concerne un nouvel appat rodenticide. The invention relates to a new rodenticide bait.

Comme on le sait, un rodenticide est un composé bien connu. I1 n'y a donc pas lieu de les décrire ici en détail. Pour l'essentiel, le plus généralement, un tel appat se compose d'un support comestible mélangé à une substance active rodenticide proprement dite. As is known, a rodenticide is a well known compound. There is therefore no need to describe them here in detail. For the most part, most generally, such a bait consists of an edible carrier mixed with an active rodenticidal substance proper.

Selon la nature du support, la substance active rodenticide est additionnée à ce support par imprégnation ou par enrobage.Depending on the nature of the support, the active substance rodenticide is added to this support by impregnation or by coating.

Comme on le sait, les rongeurs, tels que notamment les rats, les souris, les mulots, sont très méfiants. De la sorte, ils peuvent reconnaître très rapidement un produit rodenticide, qui alors, de ce fait, devient totalement inefficacewpuisqu'il n'est pas consommé. As is known, rodents, such as in particular rats, mice, field mice, are very wary. In this way, they can very quickly recognize a rodenticide product, which then, as a result, becomes totally ineffectivewas not consumed.

L'invention est destinée à pallier ces inconvénients. Elle vise un rodenticide perfectionné qui surmonte la méfiance des rongeurs, notamment des rats, des souris et des mulots, et qui soit donc plus efficace que les produits commercialisés jusqu'alors. The invention is intended to overcome these drawbacks. It aims at a perfected rodenticide which overcomes the distrust of rodents, in particular rats, mice and field mice, and which is therefore more effective than the products marketed until then.

Cet appat rodenticide perfectionné, constitué par un support comestible enrobé d'une substance active rodenticide, se caractérise en ce qu'il comporte également un arôme synthétique de poire. This improved rodenticide bait, consisting of an edible support coated with a rodenticide active substance, is characterized in that it also has a synthetic pear aroma.

En d'autres termes, l'invention consiste à ajouter un arome synthétique de poire à un appat rodenticide connu, afin de vaincre la méfiance naturelle du rat vis-à-vis de cet appât.  In other words, the invention consists in adding a synthetic pear aroma to a known rodenticide bait, in order to overcome the natural distrust of the rat vis-à-vis this bait.

On ne pouvait pas imaginer que la simple addition d'un arôme spécifique, à savoir l'arôme synthétique de poire, parmi tous les adjuvants connus, permette de surmonter et vaincre efficacement la méfiance très profonde des rongeurs. One could not imagine that the simple addition of a specific aroma, namely the synthetic aroma of pear, among all known adjuvants, would overcome and overcome effectively the very deep distrust of rodents.

Comme on le sait, l'arôme d'un produit comestible est une composition qui caractérise son goût et son odeur. Ces composés naturels peuvent être soit reconstitués (arôme artificiel), soit reproduits par synthèse (arôme synthétique). As we know, the flavor of an edible product is a composition that characterizes its taste and smell. These natural compounds can be either reconstituted (artificial flavor), or reproduced by synthesis (synthetic flavor).

Par "arôme synthétique de poire", on désigne une composition aromatique de synthèse qui donne aux aliments le goût et l'odeur de la poire. En pratique, un arôme synthétique de poire est essentiellement constitué par une solution hydroalcoolique d'extraits de vanille avec un corps comportant de la triacétine, des esters, tels que l'acétate d'héxyle ou d'amyle, des alcools cycliques tels que l'hexanol, de l'acide acététique, des aldéhydes cycliques, tels que l'aldéhyde trans-2-hexanol, et des ionones, et éventuellement des agents stabilisants. By "synthetic pear aroma" is meant a synthetic aromatic composition which gives food the taste and smell of pear. In practice, a synthetic pear flavor consists essentially of an aqueous-alcoholic solution of vanilla extracts with a body comprising triacetin, esters, such as hexyl or amyl acetate, cyclic alcohols such as l hexanol, acetetic acid, cyclic aldehydes, such as trans-2-hexanol aldehyde, and ionones, and optionally stabilizers.

Certes, il est bien connu que certains rongeurs apprécient volontiers les fruits. On a déjà proposé d'incorporer des fruits ou des extraits de fruits, voire des arômes naturels de fruits, à des appats rodenticides. Cette solution s'est avérée peu efficace. Admittedly, it is well known that some rodents like fruit. It has already been proposed to incorporate fruits or fruit extracts, or even natural fruit flavors, into rodenticide baits. This solution has proven ineffective.

Or, de manière inattendue, la sélection de l'arôme synthétique de poire provoque un attrait irrésistible pour le rongeur ,alors que d'autres arômes, notamment naturels, même des extraits de poire, donnent des résultats nettement inférieurs,et en tout cas nullement comparables.  However, unexpectedly, the selection of the synthetic pear aroma causes an irresistible attraction for the rodent, while other aromas, especially natural, even pear extracts, give significantly lower results, and in any case not at all comparable.

Avantageusement, en pratique
- l'arôme synthétique de poire est introduit par enrobage lorsque le support comestible est à base de grains, ou par mélange lorsque ce support est à base de parafine - - la quantité d'arôme synthétique de poire introduite est comprise entre 0,1 et 5 % du poids du support, et de préférence au voisinage de un pour cent en effet, on a observé que, avec une solution concentrée, si la quantité d'arôme synthétique de poire introduite excède 5 %, on augmente inutilement le prix de la composition sans obtenir d'effets supplémentaires proprotionnels, alors que si la concentration est inférieure à 0,1 %, l'effet est trop réduit ; de même, on a constaté que l'on obtenait de meilleurs résultats avec une concentration voisine de un pour cent qui, en outre, donne une odeur détectable par l'homme
- la substance active rodenticide est d'un type en soi connu ; on peut faire appel à des anti-coagulants tels que la coumafène, la chlorophacinone, la bromodialone, le difenacoum, et le brodifacoum ; on peut également utiliser des poisons à action immédiate tels que la scilliroside
- le support comestible est soit solide : grains de millet , semoule de blé, riz expansé, blocs de parafine additionnés de matières comestibles, soit liquide : eau
- les quantités de substances actives déposées sur le support comestible correspondent aux quantités usuelles et/ou réglementées ; ces quantités sont généralement de l'ordre de 0,05 à 0,005 % de subtance active par rapport au poids du support et ce, en fonction de la nature de cette substance active. Advantageously, in practice
- the synthetic pear flavor is introduced by coating when the edible support is grain-based, or by mixing when this support is based on paraffin - - the amount of synthetic pear flavor introduced is between 0.1 and 5% of the weight of the support, and preferably in the vicinity of one percent, in fact, it has been observed that, with a concentrated solution, if the quantity of synthetic pear flavor introduced exceeds 5%, the price of the product is unnecessarily increased. composition without obtaining additional proprotional effects, whereas if the concentration is less than 0.1%, the effect is too reduced; similarly, it has been found that better results are obtained with a concentration close to one percent which, in addition, gives a smell detectable by humans.
- the active substance rodenticide is of a type known per se; anti-coagulants such as coumafene, chlorophacinone, bromodialone, difenacoum, and brodifacoum can be used; immediate action poisons such as scilliroside can also be used
- the edible support is either solid: millet grains, wheat semolina, expanded rice, paraffin blocks containing edible materials, or liquid: water
- the quantities of active substances deposited on the edible support correspond to the usual and / or regulated quantities; these amounts are generally of the order of 0.05 to 0.005% of active substance relative to the weight of the support, depending on the nature of this active substance.

Ainsi, comme dans les autres composés rodenticides du commerce, le support comestible est très largement majoritaire, puisqu'il représente pratiquement 99 % en poids de la composition. Thus, as in the other commercial rodenticide compounds, the edible support is very largely in the majority, since it represents practically 99% by weight of the composition.

Le mélange des trois composants, à savoir support comestible, substance active, arôme synthétique de poire, peut s'effectuer dans n'importe quel ordre. Il suffit simplement de prendre des précautions usuelles, notamment afin que l'arôme reste bien fixé sur l'appat. The mixture of the three components, namely edible carrier, active substance, synthetic pear aroma, can be carried out in any order. It is enough simply to take usual precautions, in particular so that the aroma remains well fixed on the bait.

Comme déjà dit, l'invention réside essentiellement dans la sélection d'un composé additif particulier, à savoir l'arôme synthétique de poire, alors que d'autres arômes testés , naturels ou synthétiques, tels que des arômes de pomme, de raisin, de banane, de viande,de noix, donnent des résultats nettement inférieurs. As already said, the invention essentially resides in the selection of a particular additive compound, namely the synthetic aroma of pear, while other tested aromas, natural or synthetic, such as aromas of apple, grape, bananas, meat, nuts, give significantly lower results.

Pour tester l'efficacité d'une composition selon l'invention, on contrôle de manière connue les quantités de différentes nourritures proposées simultanément à des rats témoins pendant une durée déterminée. To test the effectiveness of a composition according to the invention, the quantities of different foods offered simultaneously to control rats are controlled in a known manner for a determined period.

Ainsi, on a constaté que pour la même nourriture additionnée de différents composés aromatiques, le rat témoin est attiré
- trois fois plus lorsque cet additif est l'arôme synthétique de poire que lorsque cet additif est l'arôme de raisin ou de la saccharine
- cinq fois plus par un arôme synthétique de poire que par un arôme gras
- et enfin huit fois plus par l'arôme synthétique de poire que par un arôme de noix. Thus, it has been found that for the same food supplemented with different aromatic compounds, the control rat is attracted
- three times more when this additive is the synthetic pear flavor than when this additive is the grape or saccharin flavor
- five times more by a synthetic pear aroma than by a fatty aroma
- and finally eight times more by the synthetic aroma of pear than by a nutty aroma.

On a constaté que l'on obtenait les meilleurs résultats en utilisant comme support comestible du riz expansé ou du millet d' Argentineenrobé à raison de 1 % d'arôme synthétique de poire. It has been found that the best results are obtained by using expanded rice or coated Argentine millet as an edible support at the rate of 1% of synthetic pear flavor.

I1 est à souligner que le riz expansé est particu fièrement adapté aux rats, alors que le millet d'Argentine,de par ses dimensions est bien adapté aux souris. It should be noted that expanded rice is particularly suitable for rats, while Argentine millet, by its dimensions, is well suited for mice.

L'appat rodenticide selon l'invention présente donc de nombreux avantages par rapport aux produits commercialisés à ce jour, puisqu'il exerce sur le rongeur un effet attractif important et que, ainsi, le rongeur pourra consommer ce produit sans se méfier et par la même, être empoisonné.  The rodenticide bait according to the invention therefore has many advantages compared to the products marketed to date, since it exerts on the rodent an important attractive effect and that, thus, the rodent will be able to consume this product without being wary and by the even be poisoned.
