Description

Composition pour lutter contre les taupesComposition for combating moles
La présente demande concerne une composition pour lutter contre les taupes, ainsi que l'utilisation d'une telle composition dans des galeries de taupes.The present application relates to a composition for combating moles, as well as the use of such a composition in mole galleries.
Dans la lutte contre les taupes, il est connu d'utiliser diverses compositions comportant un produit répulsif ou toxique, sous forme d'appâts à préparer ou prêts à l'emploi que l'on vient déposer directement dans la galerie souterraine. Il est alors nécessaire dans un premier temps de creuser le sol, puis de déposer le produit dans les galeries, ou en variante d'utiliser une canne d'injection directe dans les galeries. Afin d'attirer la taupe, des compositions taupi- cides, prêtes à l'emploi, présentées sous la forme de blocs ou de boudins ont déjà été utilisées. Elles sont cependant difficiles à mettre en oeuvre dans la mesure où il est nécessaire de mettre en forme la composition, puis de la conditionner de manière adéquate pour assurer sa conservation. Leur utilisation est délicate. Elles sont en outre peu efficaces du fait principalement de leur mauvaise conservation.In the fight against moles, it is known to use various compositions comprising a repellent or toxic product, in the form of baits to be prepared or ready to use which are just deposited directly in the underground gallery. It is then necessary to first dig the ground, then deposit the product in the galleries, or alternatively to use a direct injection cane in the galleries. In order to attract the mole, ready-to-use taupicidal compositions, presented in the form of blocks or sausages have already been used. However, they are difficult to implement in so far as it is necessary to shape the composition, then to condition it adequately to ensure its preservation. Their use is delicate. They are also ineffective mainly because of their poor conservation.
Le document FR-A-1 498 299 décrit ainsi une composition taupicide sous forme d'une pâte aqueuse conditionnée dans un tube que l'on presse pour en faire sortir un boudin souple ayant à peu près la forme d'un ver de terre. Toutefois, le fait qu'un boudin souple extrait d'un tube ressemble à peu près à un ver de terre ne suffit pas pour attirer les taupes. En particulier, la texture et le pH de cette composition taupicide ne conviennent pas, ce qui explique que ce produit a dû être retiré du marché car il n'a pu obtenir une autorisation de vente définitive.Document FR-A-1 498 299 thus describes a taupicidal composition in the form of an aqueous paste conditioned in a tube which is pressed to release a flexible rod having it roughly in the form of an earthworm. However, the fact that a flexible rod extracted from a tube roughly resembles an earthworm is not enough to attract moles. In particular, the texture and pH of this taupicide composition are not suitable, which explains why this product had to be withdrawn from the market because it could not obtain a final sales authorization.
Le document FR-A-2 659 194 décrit un appât pour la destruction de certains rongeurs amphibies nuisibles (rats musqués, ragondins) . Cet appât n'est pas prévu pour lutter contre les taupes, et le document est muet sur la recherche d'une texture ou d'un pH particuliers. On pourra également se référer au document BE-A-1 000 534 qui décrit une composition en poudre pour l'extermination des rats.Document FR-A-2 659 194 describes a bait for the destruction of certain harmful amphibious rodents (muskrats, nutria). This bait is not intended to fight against moles, and the document is silent on the search for a particular texture or pH. Reference may also be made to document BE-A-1,000,534 which describes a powder composition for the extermination of rats.
Le document JP-A-03 292 841 décrit un appât chimique en bloc moulé, et le document JP-A-55 108 407 un agent gélifiant.Document JP-A-03 292 841 describes a molded block chemical bait, and document JP-A-55 108 407 a gelling agent.
Le document EP-A-0 078 737 illustre une canne à long tube servant à injecter un produit répulsif ou toxique directement dans une galerie de taupe.Document EP-A-0 078 737 illustrates a long tube cane used for injecting a repellant or toxic product directly into a gallery of moles.
Le document FR-A-2 663 506 décrit une poudre taupicide destinée à former extemporanément un boudin après mouillage de ladite poudre. Le document EP-A-0 811 322 décrit un appât dont l'élément d'appétence provient de la solidification du liquide issu d'une graisse ou d'une huile. Cet appât sous forme de bloc est en réalité plutôt raticide ou souricide que taupicide, car les taupes se nourrissent presque exclusivement de vers de terre et de larves d'insectes.Document FR-A-2 663 506 describes a taupicide powder intended to form a tube immediately after wetting said powder. The document EP-A-0 811 322 describes a bait whose element of palatability comes from the solidification of the liquid from a fat or an oil. This bait in the form of a block is actually more rat poisonous or micide than taupicide, because moles feed almost exclusively on earthworms and insect larvae.
Les documents EP-A-0 097 093, FR-A-2 668 892 et EP-A-0 240 826 illustrent également divers appâts pour lutter contre les animaux nuisibles, mais qui sont inhomo- logables et/ou inopérants contre les taupes . Le document FR-A-2 750 008, publié postérieurement à la date de priorité de la présente demande, décrit enfin un appât anti-taupes dont l'agent appétent est à base de protéines d'insectes. Toutefois, ce document est muet sur la recherche d'une texture ou d'un pH particuliers. La présente invention a pour but de résoudre les inconvénients précités et de proposer une composition taupicide qui soit à la fois efficace et homologable comme telle, et qui puisse être aisément mise en forme de boudin souple . La composition visée par l'invention est du type comportant un produit toxique, et elle est caractérisée en ce que la texture, l'appétence, la teneur en eau et le pH de ladite composition sont sensiblement identiques respectivement à la texture, à l'appétence, à la teneur en eau, et au pH d'un lombric.The documents EP-A-0 097 093, FR-A-2 668 892 and EP-A-0 240 826 also illustrate various baits for combating pests, but which are inhomologable and / or ineffective against moles. Document FR-A-2 750 008, published after the priority date of the present application, finally describes an anti-mole bait whose palatable agent is based on insect proteins. However, this document is silent on the search for a particular texture or pH. The object of the present invention is to solve the aforementioned drawbacks and to propose a taupicide composition which is both effective and homologable as such, and which can be easily formed into a flexible tube. The composition targeted by the invention is of the type comprising a toxic product, and it is characterized in that the texture, palatability, water content and pH of said composition are substantially identical respectively to the texture, palatability, water content, and pH of a earthworm.
On parvient ainsi à créer un véritable leurre reproduisant fidèlement les propriétés physico-chimiques et organoleptiques du lombric, ce qui permet de tromper la taupe qui ingère le produit sans méfiance avec la percep- tion de ce qui constitue 90% de sa nourriture habituelle.We thus manage to create a real lure faithfully reproducing the physico-chemical and organoleptic properties of earthworms, which makes it possible to deceive the mole which ingests the product without distrust with the perception of what constitutes 90% of its usual food.
De préférence, la composition comporte pour la texture au moins 60 % d'eau en poids et un agent gélifiant, des protéines animales pour l'appétence, et un pH compris entre 6 et 8, en étant de préférence voisin de 6,2 (pH moyen de la chair des lombrics) .Preferably, the composition comprises for the texture at least 60% water by weight and a gelling agent, animal proteins for palatability, and a pH of between 6 and 8, being preferably close to 6.2 ( average earthworm flesh pH).
Une telle composition permet alors d'obtenir un appât dont la composition en protéines et en eau sont proches de celles des lombrics qui constituent l'essentiel de l'alimentation et de l'apport en eau des taupes. En outre, la texture de la composition obtenue permet d'utiliser cette composition dans un dispositif d'injection et ainsi de mouler directement sur le site la composition sous la forme d'un cylindre allongé ou autre. A titre d'exemple, l'agent gélifiant est un polymère d'acide polyacrylique réticulé épaissi en présence d'un catalyseur, lequel catalyseur est par exemple une base organique, telle que du triéthanol aminé, dans une proportion double de celle du polymère d'acide polyacrylique, cette proportion étant de préférence sensiblement égale à 2 % en poids et la proportion en eau étant sensiblement égale à 75% en poids.Such a composition then makes it possible to obtain a bait whose protein and water composition are close to those of earthworms which constitute the main part of the diet and the water supply of moles. In addition, the texture of the composition obtained makes it possible to use this composition in an injection device and thus to mold the composition directly on the site in the form of an elongated cylinder or the like. By way of example, the gelling agent is a crosslinked polyacrylic acid polymer thickened in the presence of a catalyst, which catalyst is for example an organic base, such as amino triethanol, in a proportion double that of the polymer d polyacrylic acid, this proportion preferably being substantially equal to 2% by weight and the proportion of water being substantially equal to 75% by weight.
De préférence, la composition comprend comme protéines animales de la farine de poisson dans une proportion comprise entre 5% et 10 % en poids. Cette farine de poisson joue un rôle d'attractif à l'égard des taupes et contribue notamment à attirer les taupes vers la composition taupicide.Preferably, the composition comprises, as animal proteins, fish meal in a proportion of between 5% and 10% by weight. This fish meal plays an attractive role with regard to moles and contributes in particular to attract moles towards the taupicide composition.
Avantageusement encore, la composition est conditionnée, lorsqu'elle est introduite dans une galerie de taupe, sous la forme de boudins mous d'environ 3 à 4 mm de diamètre, lesquels boudins mous ont de préférence une longueur voisine de 5 à 6 cm : on parvient ainsi à reproduire également les caractéristiques dimensionnelles du lombric, ce qui renforce encore l'efficacité du leurre. Selon un deuxième aspect de l'invention, la composition taupicide est introduite dans une galerie de taupe au moyen d'une canule d'injection montée sur un corps de piston contenant ladite composition. La composition est alors de préférence conservée en étant prête à l'emploi dans le corps de piston. On pourra pour cela utiliser les matériels de type standard qui sont communément utilisés pour appliquer du mastic ou de la colle.Advantageously still, the composition is conditioned, when it is introduced into a mole gallery, in the form of soft tubes of approximately 3 to 4 mm in diameter, which soft tubes preferably have a length close to 5 to 6 cm: this also manages to reproduce the dimensional characteristics of the earthworm, which further enhances the effectiveness of the lure. According to a second aspect of the invention, the taupicide composition is introduced into a mole gallery by means of an injection cannula mounted on a piston body containing said composition. The composition is then preferably stored while being ready for use in the piston body. This can be done by using standard type materials which are commonly used to apply sealant or glue.
Cette utilisation de la composition conforme à l'invention permet de délivrer une quantité de produits taupicides sans risque pour l'utilisateur de toucher le produit .This use of the composition in accordance with the invention makes it possible to deliver a quantity of taupicide products without risk for the user to touch the product.
D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will appear in the description below.
Au dessin annexé, donné à titre d'exemple non limitatif :In the appended drawing, given by way of nonlimiting example:
- la figure 1 est une vue schématique illustrant l'utilisation de la composition conforme à l'invention.- Figure 1 is a schematic view illustrating the use of the composition according to the invention.
La composition taupicide conforme à l'invention va tout d'abord être décrite. Les pourcentages indiqués ci-après dans les formulations sont des pourcentages massiques .The taupicide composition in accordance with the invention will first be described. The percentages given below in the formulations are mass percentages.
La composition comporte de préférence au moins 60The composition preferably comprises at least 60
% d'eau en poids, un produit toxique, des protéines animales et un agent gélifiant, et son pH est compris entre 6 et 8 , en étant de préférence voisin de 6 , 2 , de sorte que la texture, l'appétence, la teneur en eau et le pH de la composition sont respectivement sensiblement identiques à celles et celui d'un lombric.% water by weight, a toxic product, animal proteins and a gelling agent, and its pH is between 6 and 8, preferably being close to 6, 2, so that the texture, palatability, water content and pH of the composition are respectively substantially identical to that of a earthworm.
De manière classique, la texture est définie par les valeurs de viscosité, d'élasticité, de dureté, d'adhérence et de cohésion de la composition, selon les termes de la norme NF V 00 150.Conventionally, the texture is defined by the viscosity, elasticity, hardness, adhesion and cohesion values of the composition, according to the terms of standard NF V 00 150.
Le produit toxique peut être à titre d'exemple de l' alphachloralose, de la crimidine, de la chlorophacinone, de scilliroside, ou de la arfarine .The toxic product can be, for example, alphachloralose, crimidine, chlorophacinone, scilliroside, or arfarin.
Lorsque la composition est destinée à lutter contre les taupes, la proportion d' alphachloralose peut être comprise entre 8 % et 12 % en poids, et de préférence égale à 10%. Cette quantité est suffisante pour éliminer les taupes lors de l'ingestion du produit.When the composition is intended for combating moles, the proportion of alphachloralose can be between 8% and 12% by weight, and preferably equal to 10%. This quantity is sufficient to eliminate the moles during the ingestion of the product.
La composition peut en outre comprendre un agent anti-desséchant, tel que du glycerol ou du sorbitol ou un mélange des deux, dans une proportion comprise entre 3% et 6% en poids .The composition can also comprise an anti-drying agent, such as glycerol or sorbitol or a mixture of the two, in a proportion of between 3% and 6% by weight.
Le glycerol améliore en particulier la résistance au séchage et la cohésion de la composition obtenue.The glycerol in particular improves the resistance to drying and the cohesion of the composition obtained.
L'agent gélifiant peut être une gélatine pure alimentaire, telle que du Cryogel ® (marque déposée de la société Tessenderlo Chemie NV) qui présente l'avantage de se dissoudre et se figer à froid.The gelling agent can be a pure food gelatine, as the cryogel ® (trademark of the company Tessenderlo Chemie NV) has the advantage of dissolving and freezing cold.
La proportion de gélatine est comprise entre 5% et 15% en poids, et de préférence égale à 8% et la proportion d'eau est comprise entre 60% et 75% en poids, et de préférence égale à 69%, ce qui correspond sensiblement à la valeur réelle rencontrée pour le lombric.The proportion of gelatin is between 5% and 15% by weight, and preferably equal to 8% and the proportion of water is between 60% and 75% by weight, and preferably equal to 69%, which corresponds substantially at the actual value encountered for earthworms.
Ces proportions permettent d'obtenir une composition ni trop liquide, ni trop compacte, qui se prête bien à l'injection par une canule dans une taupinière. L'agent gélifiant peut encore être un polymère d'acide polyacrylique réticulé, tel que le Carbopol" (marque déposée de la société BF Goodrich Co . ) , épaissi en présence d'un catalyseur. Ce polymère est obtenu par la réaction d'un monomère d'acide acrylique en présence d'un solvant tel que de 1 ' éthylacétate/cyclohexane . Le catalyseur est alors de préférence une base organique, telle que du triéthanol aminé, dans une proportion double de celle du polymère d'acide polyacrylique.These proportions make it possible to obtain a composition that is neither too liquid nor too compact, which lends itself well to injection by a cannula in a molehill. The gelling agent may also be a crosslinked polyacrylic acid polymer, such as Carbopol " (registered trademark of the company BF Goodrich Co.), thickened in the presence of a catalyst. This polymer is obtained by the reaction of an acrylic acid monomer in the presence of a solvent such as ethyl acetate / cyclohexane. The catalyst is then preferably an organic base, such as amino triethanol, in a proportion double that of the polyacrylic acid polymer.
Ce catalyseur renforce le pouvoir gélifiant du Carbopol'" en présence d'eau et permet également de relever le pH alors descendu à une valeur proche de 3 , en le ramenant à une valeur comprise entre 6 et 8 , et de préfé¬ rence voisine de 6,2, donc sensiblement égale au pH d'un lombric .This catalyst enhances the gelling power Carbopol "in the presence of water and also allows to raise the pH then lowered to a value close to 3, by reducing it to a value between 6 and 8, and pref ¬ neighboring ence 6.2, therefore approximately equal to the pH of a earthworm.
La proportion de polymère d'acide polyacrylique est sensiblement égale à 2% en poids et la proportion en eau est sensiblement égale à 75%.The proportion of polyacrylic acid polymer is substantially equal to 2% by weight and the proportion of water is substantially equal to 75%.
On obtient ainsi une composition dont la texture reproduit la texture d'un vrai lombric tout en étant suffisamment compacte et dure pour pouvoir être injectée dans une galerie de taupe.A composition is thus obtained, the texture of which reproduces the texture of a real earthworm while being sufficiently compact and hard to be able to be injected into a gallery of moles.
De la farine de poisson est avantageusement utilisée pour apporter des protéines animales à la composi¬ tion taupicide. La farine de poisson permet de renforcer l'effet attractif du produit à l'égard des taupes. La farine de poisson est par exemple introduite dans une proportion comprise entre 5% et 10% en poids.Of fishmeal is advantageously used to make animal protein composi ¬ talpicide. Fishmeal makes it possible to reinforce the attractive effect of the product with regard to moles. Fish meal is for example introduced in a proportion of between 5% and 10% by weight.

Le pH de la composition taupicide est également semblable à celui d'un lombric.The taupicidal compositions obtained have a texture identical to that of earthworms and water and protein contents substantially equal to those of earthworms. The pH of the taupicide composition is also similar to that of a earthworm.
En outre, des conservateurs classiques sont introduits dans la composition afin d'éviter l'apparition éventuelle de moisissures dans le produit.In addition, conventional preservatives are introduced into the composition in order to avoid the possible appearance of mold in the product.
Un produit pour éviter le dessèchement de la composition peut être ajouté à la composition. Un produit employé couramment dans l'alimentation humaine peut être utilisé .A product to prevent drying of the composition can be added to the composition. A product commonly used in human food can be used.
La composition qui vient d'être décrite est de préférence conditionnée, lorsqu'elle est introduite dans une galerie de taupe, sous la forme de boudins mous d'environ 3 à 4 mm de diamètre, lesdits boudins mous ayant une longueur voisine de 5 à 6 cm. On parvient alors à reproduire en plus les dimensions mêmes d'un véritable lombric . En référence à la figure 1, la composition taupicide est introduite lors de son utilisation dans une galerie de taupe 3, au moyen par exemple d'une canule d'injection 5 montée sur un corps de piston 1 contenant la composition. La composition taupicide peut être conservée à l'abri de la lumière et pour éviter la déshydratation dans le corps de piston 1, en étant prête à l'emploi. Lors de l'utilisation, il suffit de fixer la canule 5 à une extrémité du corps de piston 1 et d'actionner une tige de piston 2 pour distribuer une quantité de produit sous une forme allongée 6 par un ou des orifices de sortie de la canule 5. En l'espèce, on a prévu deux orifices latéraux 4, ce qui favorise le développement en boudins. Ces orifices seront naturellement calibrés pour correspondre au diamètre de 3 à 4 mm recherché. En outre, on pourra prévoir une graduation ou un repérage sur la tige de piston 2, permettant de visualiser facilement une course déterminée qui correspond à la longueur de boudin extrudé désirée (5 à 6 cm par exemple) ; en variante, on pourra déterminer la longueur extrudee par un comptage du nombre de courses de la tige de piston.The composition which has just been described is preferably packaged, when it is introduced into a gallery of mole, in the form of soft tubes of approximately 3 to 4 mm in diameter, said soft tubes having a length close to 5 to 6 cm. We then manage to reproduce in addition the very dimensions of a real earthworm. With reference to FIG. 1, the taupicide composition is introduced during its use into a mole gallery 3, by means for example of an injection cannula 5 mounted on a piston body 1 containing the composition. The taupicide composition can be stored at protected from light and to avoid dehydration in the piston body 1, by being ready for use. In use, it suffices to attach the cannula 5 to one end of the piston body 1 and actuate a piston rod 2 to dispense a quantity of product in an elongated form 6 through one or more outlet orifices of the cannula 5. In the present case, two lateral orifices 4 have been provided, which promotes the development of tubes. These orifices will naturally be calibrated to correspond to the diameter of 3 to 4 mm sought. In addition, a graduation or a marking can be provided on the piston rod 2, making it possible to easily visualize a determined stroke which corresponds to the desired length of extruded tube (5 to 6 cm for example); alternatively, the extruded length can be determined by counting the number of strokes of the piston rod.
On pourra aussi utiliser pour l'extrusion de la composition un matériel du type à cartouche et pistolet applicateur déjà largement répandu pour l'application de colle ou de mastic.It is also possible to use for the extrusion of the composition a material of the cartridge and applicator gun type already widely used for the application of glue or mastic.
Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation décrit ci-dessus, et de nombreuses modifications peuvent être apportées sans sortir du cadre de l'invention. Of course, the invention is not limited to the embodiment described above, and many modifications can be made without departing from the scope of the invention.
