Description

J. L'arrêté du 26 décembre 2012 classe le frelon asiatique (Vespa Velutina Nigrithorax) parmi les « dangers sanitaires de deuxième catégorie » pour les abeilles domestiques. Le dispositif de cette invention vise à diminuer la population de frelons asiatiques dans leur nid au moyen d'un support insecticide placé sur le dos d'un frelon cobaye. Les méthodes traditionnelles consistent à déposer des pièges mécaniques, chimiques ou électriques et des appâts toxiques dans les lieux qu'ils fréquentent. Une deuxième méthode consiste à éloigner les attaques des frelons en enfermant les ruches dans des cages grillagées où seules les abeilles peuvent entrer et sortir. Une troisième méthode consiste à rechercher les nids de frelons et à les détruire. La progression annuelle du nombre de frelons et leur extension géographique montrent non seulement l'insuffisance des méthodes traditionnelles devant ce fléau mais aussi des impacts sur la biodiversité. A savoir : - Le recours aux pièges ou aux appâts n'est pas sélectif à l'heure actuelle et cause d'importants dégâts à la biodiversité. - La protection des ruches par des grilles est censée éviter les attaques de frelons aux abords du rucher. Ce procédé n'empêche pas l'attaque des abeilles loin de leurs ruches et ne permet pas de contrôler la progression des frelons. Ces deux méthodes ne permettent pas le contrôle de la progression des frelons puisqu'elles visent l'effet et non pas la source de la prolifération des frelons asiatiques. 0 - La solution de détruire le nid est efficace mais nécessite de repérer d'abord le nid de frelons, or les nids de frelons asiatiques ne sont pas toujours faciles à détecter car ils sont installés de préférence en haut des grands arbres, cachés sous les feuillages et parfois à quelques centaines de mètres du lieu de la prédation. Une fois le nid repéré, il faut des moyens en hommes et en matériels pour l'atteindre et le détruire. Cette intervention est onéreuse et expose les hommes aux dangers de la hauteur et aux attaques des frelons. Le procédé utilisé dans cette invention ne présente pas les inconvénients des méthodes susmentionnées puisqu'en ciblant uniquement le frelon asiatique, il respecte la biodiversité et ne présente pas un risque de contamination de l'eau, de la terre, de la faune et de la flore. Il permet d'atteindre le nid du frelon à distance, il n'y a donc pas besoin de localiser le nid, ni d'avoir à faire intervenir des hommes. Cette invention consiste à contaminer le Md de frelons asiatiques par un frelon cobaye qui transporte un insecticide. La figure 1 montre le dispositif de l'invention composé successivement d'une couche adhésive (2), d'une couche étanche (3) et d'un support (4) contenant une substance insecticide, le tout est fixé sur le dos d'un frelon (1). La couche 3 5 étanche constitue la partie intermédiaire entre le corps et le support et sa fonction est d'empêcher le contact direct de la substance toxique avec le corps du frelon cobaye. Avec ce dispositif, la substance insecticide peut être choisie parmi les substances qui agiront soit par contact, soit par ingestion, soit par inhalation, soit par une combinaison de ces différents modes d'action. Les dispositifs de cette invention sont: La première phase consiste à capturer un frelon asiatique (cobaye). Il est nécessaire que le frelon cobaye soit capturé vivant et sans lésions, dans les lieux qu'il fréquente notamment à proximité des ruchers d'abeille domestique. La seconde phase de l'intervention est d'anesthésier le frelon afin de fixer le dispositif sur lui sans s'exposer à des risques. Une méthode facile et à la portée de tous est d'anesthésier le frelon par le froid. Pour cela, on met le frelon capturé dans un bocal aéré et on met le bocal 'D pendant quelques minutes dans un congélateur. On surveille l'état d'anesthésie du frelon et on le sort au moment où le frelon courbe son abdomen et où ses pattes bougent à peine ou à l'instant où il vient de s'immobiliser. Une durée d'enfermement trop longue dans le congélateur risque de tuer le frelon. La résistance au froid et la durée de l'anesthésie par le froid peuvent varier selon les frelons. I 5 La troisième phase consiste à fixer le dispositif, grâce à une couche adhésive, sur le dos du frelon encore anesthésié. L'emplacement du dispositifs ne doit pas empêcher l'envol, ni déranger les mouvements de la tête du frelon. Il est préférable que l'inter v'ention soit effectuée rapidement, avant la dissipation de l'effet d'anesthésie, afin de ne pas perturber le frelon et d'éviter tout risque pour le manipulateur.J. The Decree of 26 December 2012 classifies the Asian hornet (Vespa Velutina Nigrithorax) as a "second-class health hazard" for honey bees. The device of this invention aims to reduce the population of Asian hornets in their nest by means of an insecticidal carrier placed on the back of a guinea pig hornet. Traditional methods include placing mechanical, chemical or electrical traps and toxic baits in the places they frequent. A second method is to remove the attacks of hornets by enclosing the hives in wire cages where only the bees can enter and leave. A third method is to search for nests of hornets and destroy them. The annual increase in the number of hornets and their geographical extension show not only the inadequacy of traditional methods in the face of this scourge but also impacts on biodiversity. Namely: - The use of traps or baits is not selective at present and causes significant damage to biodiversity. - The protection of the hives by grids is supposed to avoid attacks of hornets in the vicinity of the apiary. This process does not prevent the attack of bees away from their hives and does not control the progress of hornets. These two methods do not allow the control of the progress of hornets since they aim at the effect and not the source of the proliferation of Asian hornets. 0 - The solution to destroy the nest is effective but needs to first identify the nest of hornets, or the nests of Asian hornets are not always easy to detect because they are installed preferably at the top of large trees, hidden under the foliage and sometimes a few hundred meters from the place of predation. Once the nest is spotted, it takes means in men and materials to reach and destroy it. This intervention is expensive and exposes men to the dangers of height and attacks of hornets. The method used in this invention does not have the drawbacks of the above-mentioned methods since, by targeting only the Asian hornet, it respects biodiversity and does not pose a risk of contamination of water, soil, fauna and water. flora. It allows to reach the nest of the hornet at a distance, so there is no need to locate the nest, or to have to involve men. This invention involves contaminating the Md of Asian hornets with a guinea pig hornet that carries an insecticide. FIG. 1 shows the device of the invention successively composed of an adhesive layer (2), a waterproof layer (3) and a support (4) containing an insecticidal substance, the whole is fixed on the back of a hornet (1). The watertight layer forms the intermediate part between the body and the support and its function is to prevent the direct contact of the toxic substance with the body of the guinea-pig hornet. With this device, the insecticidal substance can be chosen from the substances that will act either by contact, by ingestion, by inhalation, or by a combination of these different modes of action. The devices of this invention are: The first step is to capture an Asian hornet (guinea pig). It is necessary that the guinea pig hornet be captured alive and without lesions, in the places that it frequents in particular near the bee apiaries. The second phase of the intervention is to anesthetize the hornet in order to fix the device on him without exposing himself to risks. An easy and easy method for all is to anesthetize the hornet by the cold. For this, we put the captured hornet in a ventilated jar and put the jar 'D for a few minutes in a freezer. The anesthesia state of the hornet is monitored and released when the hornet bends its abdomen and where its legs are barely moving or when it has just stopped. Too much time in the freezer will kill the hornet. Cold resistance and duration of cold anesthesia may vary between hornets. The third step is to fix the device, through an adhesive layer, on the back of the hornet still anesthetized. The location of the device must not prevent the flight or disturb the movements of the hornet's head. It is preferable that the intervention be performed quickly, before the dissipation of the anesthetic effect, so as not to disturb the hornet and to avoid any risk for the manipulator.

20 La quatrième phase est de libérer le frelon, muni du dispositif, à l'endroit ou à proximité de l'endroit où il a été capturé afin de ne pas désorienter le frelon par rapport à l'emplacement de son nid. Lorsque ce frelon porteur du dispositif rejoindra ses congénères, il les mettra en contact avec le produit contenu dans le support. Ce procédé est rapide et efficace, c'est une intervention à distance et peu onéreuse, elle peut 2 être répétée autant de fois que c'est nécessaire. C'est un procédé ciblé qui ne présente aucun danger ni pour les abeilles mellifères et polinisatrices, ni pour les autres espèces, il ne risque pas de polluer l'eau, la terre et les végétaux. Pour augmenter le taux de la réussite du retour du frelon à son nid, il est préférable d'opérer vers la fin d'après-midi car le frelon asiatique est un animal diurne qui rejoint son foyer au T30 coucher du soleil. L'application industrielle de ce dispositif, sous forme de pastilles prêtes à l'emploi, aurait l'avantage de contrôler la structure du dispositif ainsi que la qualité et la dose du produit utilisé. Elle faciliterait l'application du procédé, d'une part en réduisant le temps de fixation du dispositif sur le frelon cobaye, et donc les accidents dus au réveil du frelon, et d'autre part, 3 5 en évitant les risques liés à la manipulation des produits contenus dans le dispositif.The fourth phase is to release the hornet, equipped with the device, at or near the place where it was captured so as not to disorient the hornet with respect to the location of its nest. When this hornet carrying the device will join his congeners, he will put them in contact with the product contained in the support. This process is fast and efficient, it is a remote intervention and inexpensive, it can be repeated as many times as necessary. It is a targeted process that is safe for honey bees and polinizers, or for other species, it is not likely to pollute water, soil and plants. To increase the rate of successful return of the hornet to its nest, it is better to operate towards the end of the afternoon because the Asian hornet is a diurnal animal that joins his home at T30 sunset. The industrial application of this device, in the form of ready-to-use tablets, would have the advantage of controlling the structure of the device as well as the quality and the dose of the product used. It would facilitate the application of the method, on the one hand by reducing the fixing time of the device on the guinea-pig hornet, and therefore the accidents due to the awakening of the hornet, and on the other hand, by avoiding the risks associated with the handling of the products contained in the device.
