Abstract
Description
La présente invention concerne un distributeur perfectionné de phéromone. The present invention relates to an improved pheromone dispenser.
De façon générale l'invention concerne des procédés et des dispositifs pour lutter contre les insectes et plus particulièrement un dispositif perfectionné pour distribuer des phéromones photodégradables afin d'attirer les insectes et/ou perturber l'accouplement. In general, the invention relates to methods and devices for controlling insects and more particularly to an improved device for dispensing photodegradable pheromones to attract insects and / or disrupt mating.
Le brevet US 4 017 030 décrit un conduit microcapillaire utilisé pour contenir et libérer de façon réglée des attractifs ou leurres pour insectes tels que les phéromones. Les conduits microcapillaires des dispositifs sont généralement décrits comme constitués de "matières polymères naturelles ou synthétques obtenues selon l'un quelconque des procédés couramment employés pour la production des fibres artificielles. Des matières utiles comprennent les polyesters, les polyoléfines, les acryliques, les modacryliques, les polyamides, etc."
Beaucoup des phéromones qui peuvent titre contenues dans les conduits microcapillaires de l'art antérieur et en être libérées aans des conditions réglées sont photosensibles, c'est-à-dire se dégradent par exposition aux rayons ultraviolets.Lorsque les dispositifs à conduits microcapillaires contenant les phEnnTnes photosensibles sont '. dans des champs et des sites semblables fréquentés par les insectes, ils peuvent 9- tre exposés à la lumière solaire, si bien que la phéromone contenue est dégradée au point d'tre détruite très rapidement.US Patent 4,017,030 discloses a microcapillary conduit used to contain and release in a controlled manner attractants or lures for insects such as pheromones. The microcapillary conduits of the devices are generally described as consisting of "natural or synthetic polymer materials obtained by any of the processes commonly employed for the production of artificial fibers." Useful materials include polyesters, polyolefins, acrylics, modacrylics, and the like. polyamides, etc. "
Many of the pheromones that may be contained in the microcapillary conduits of the prior art and released therefrom under controlled conditions are photosensitive, i.e., degrade upon exposure to ultraviolet rays.When microcapillary conduit devices containing the photosensitive Phenomena are. in fields and similar sites frequented by insects, they can be exposed to sunlight, so that the contained pheromone is degraded to the point of being destroyed very rapidly.
Selon le procédé de l'invention les phéromones contenues dans un conduit microcapillaire sont protegées contre la dégradation par la lumière ultraviolette ce qui prolonge la durée de vie du dispositif comme leurre pour insectes et/ou dispositif perturbant l'accouplement. According to the process of the invention pheromones contained in a microcapillary conduit are protected against degradation by ultraviolet light which prolongs the life of the device as an insect lure and / or device disrupting the coupling.
L'invention concerne un dispositif pour la dissémination d'une phéromone dégradable par les rayons ultraviolets qui comprend un récipient destiné à contenir la phéro mone constitué d'un conduit microcapillaire perméable aux rayons ultraviolets, caractérisé en ce qu'il est muni d'un écran arrêtant les ultraviolets associé au conduit microcapillaire. The invention relates to a device for the dissemination of an ultraviolet-degradable pheromone which comprises a container for containing the pheromone consisting of a microcapillary conduit permeable to ultraviolet rays, characterized in that it is provided with a ultraviolet-stopping screen associated with the microcapillary duct.
La figure unique annexée est une coupe en élévation d'un dispositif constituant un mode de réalisation préféré de l'invention. The single appended figure is an elevational section of a device constituting a preferred embodiment of the invention.
Les modes de réalisation préférés de l'invention vont maintenant entre décrits. The preferred embodiments of the invention will now be described.
La figure annexée est une coupe en élévation d'un dispositif constituant un mode de réalisation de l'invention. The attached figure is an elevational section of a device constituting an embodiment of the invention.
Le dispositif comprend un conduit microcapillaire 2 ayant une lumière 4 fermée à une extrémité par un bouchon 6 de ciment époxy ou d'une matière semblable. La lumière 4 est rèmplie d'une phéromone qui peut se vaporiser par l'extrémité ouverte du conduit 2. La phéromone 8 forme de préférence un ménisque 10 concave à ltextrémité ouverte car la matière choisie pour la fabrication du conduit 2 est mouillable.The device comprises a microcapillary conduit 2 having a lumen 4 closed at one end by a plug 6 of epoxy cement or a similar material. The lumen 4 is replenished with a pheromone which can vaporize through the open end of the duct 2. The pheromone 8 preferably forms a concave meniscus 10 at the open end because the material chosen for the manufacture of the duct 2 is wettable.
La phéromone 8 peut être une phéromone vaporisable connue quelconque caractérisée notamment par sa dégradabilité par exposition d un rayonnement ultraviolet. On peut citer comme exemples caractéristiques de telles phéromones; le ( Z) -1;-hexauécénal, le (E > -ll-tétradécénal, le fZi-9-té- tradécénal, le (7,Z)-11,13-hexadecadiénal et similaires. Pheromone 8 may be any known vaporizable pheromone characterized in particular by its degradability by exposure of ultraviolet radiation. Typical examples of such pheromones include; (Z) -1; -hexauecenal, (E) -ll-tetradecenal, fZi-9-tetecenephenal, (7, Z) -11,13-hexadecadienal and the like.
Dans l'art antérieur, les conduits microcapillaires 2 utilisés pour contenir les phéromones 8 et permettre leur liberation réglée ont été fabriqués en matières perméables aux rayons tatraviolets, telles que des résines polymères synthétiques perméables aux rayons ultraviolets, comme le polytéréphtalate d'éthylène. Le perfectionnement de l'invention comprend l'association d'un écran arrêtant les ul trariolets ou conduit microcapillaire 2. On peut réaliser l'association de diverses façons.La façon préférée consiste à choisir comme matière du conduit ou tube 2 une matière imperméable aux rayons ultraviolets- On peut rendre des résines polymères synthétiques imperméables aux rayons ultra violets en formulant par exemple les résines en incluant des agents absorbants des rayons ultraviolets. On connut une grande diversité d'absorbants des rayons ultraviolets ainsi que leur procédé de préparation. In the prior art, the microcapillary conduits 2 used to contain the pheromones 8 and allow their controlled release have been made of tetraviolet-permeable materials, such as synthetic polymeric resins permeable to ultraviolet rays, such as polyethylene terephthalate. The improvement of the invention comprises the combination of a screen stopping the ul trariolets or microcapillary conduit 2. The association can be achieved in various ways. The preferred way is to choose as the material of the conduit or tube 2 a material impervious to ultraviolet rays. Synthetic polymeric resins can be made impermeable to ultraviolet rays by, for example, formulating the resins by including ultraviolet absorbers. A wide variety of ultraviolet absorbers and their process of preparation were known.
Par exemple la US Defensive Publication 1998, 013 (2 Septembre 1980) décrit des composés de formule
dans laquelle R1 représente un atome d'hydrogène ou un radical alcoxy ayant 1 à 12 atomes de carbone, R2 représente un atome dthydrogène, un groupe acide sulfonique ou son sel de sodium, R3 représente un atome d'hydrogêne ou un radical hydroxy et R4 représente un atome dhydrogène, un radical hydroxy ou un radical méthoxy.For example, US Defensive Publication 1998, 013 (September 2, 1980) discloses compounds of formula
in which R 1 represents a hydrogen atom or an alkoxy radical having 1 to 12 carbon atoms, R 2 represents a hydrogen atom, a sulfonic acid group or its sodium salt, R 3 represents a hydrogen atom or a hydroxyl radical and R 4 represents a hydrogen atom, a hydroxyl radical or a methoxy radical.
Ces composés sont compatibles avec les pheromones qu'ils protègent en empêchant leur dégradation par les rayons ultraviolets. On peut combiner les composés aux résines selon des techniques classiques et avec un appareillage classique ; par exemple selon des techniques de broyage, de dispersion à ltétat fondu et similaires. On mélange une partie suffisante de l'absorbant de la lumière ultraviolette à la résine pour rendre cette dernière imperméable aux rayons ultraviolets. These compounds are compatible with the pheromones they protect by preventing their degradation by ultraviolet rays. The compounds can be combined with the resins according to conventional techniques and with conventional equipment; for example, by grinding, melt dispersing and the like. A sufficient portion of the ultraviolet light absorbent is mixed with the resin to render the resin impervious to ultraviolet light.
D'autres additifs que l'on peut combiner aux résines polymères synthétiques pour former les fibres creuses 2 comprennent le charbon, les noirs de carbone et les colorants ou pigments semblables qui sont opaques aux rayons ultraviolets et dont la présence rend la résine sous forme d'un conduit microcapillaire imperméable aux rayons ultra violets. Beaucoup des résines ainsi formulées sont disponi bles dans le commerce. Other additives which can be combined with synthetic polymeric resins to form hollow fibers 2 include carbon, carbon blacks and similar dyes or pigments which are opaque to ultraviolet light and whose presence renders the resin in the form of a microcapillary conduit impervious to ultraviolet rays. Many of the resins thus formulated are commercially available.
Dans un mode de réalisation préféré de l'inven- tion, la résine contenant écran arrentant les rayons ultraviolets à partir de laquelle est constitué le conduit microcapillaire contient aussi un antioxydant. In a preferred embodiment of the invention, the ultraviolet-arresting screen-containing resin from which the microcapillary conduit is made also contains an antioxidant.
Un autre moyen pour associer un écran arrêtant les rayons ultraviolets aux conduits microcapillaires consiste à revêtir les fibres d'un revetement imperméable aux rayons ultraviolets par exemple d'un pigment foncé. Another means of associating an ultraviolet-arresting screen with microcapillary conduits is to coat the fibers with a coating impervious to ultraviolet rays, for example a dark pigment.
L'exemple suivant décrit la préparation et l'application du meilleur mode de réalisation de l'invention mais qui n'est pas limitatif. The following example describes the preparation and application of the best embodiment of the invention but which is not limiting.
Exemple
On se munit d'une certaine quantité d'un polymere thermoplastique de type polyoxyméthylène obtenu par polymèrisation anioiiique du formaldéhyde pour former un polymère linéaire ayant des motifs de formule O CH2 -- o - CH2- O --CH2-- (Celcon, Celanese Chemical Co,, Division of Celanese Corp., N. Y., N.Y.). On se munit également d'une certaine quantité de Celcon contenant un pigment noir (Black Celcon) rendant le polymère thermoplastique imperméable aux rayons ultraviolets. On se munit également d'une résine Black Celcon formulée à 1 /o en poids avec un antioxydant par exemple le
Bamox 20 BA, (Swift & Co.) dont llingredient-aotif principal est le 2,6-di-(tert-butyl)-p- crésol.Example
A certain amount of a polyoxymethylene-type thermoplastic polymer obtained by analogous polymerization of formaldehyde is provided to form a linear polymer having units of the formula ## STR2 ## (Celcon, Celanese Chemical Co, Division of Celanese Corp., NY, NY). A certain amount of Celcon containing a black pigment (Black Celcon) is also provided, rendering the thermoplastic polymer impervious to ultraviolet rays. It is also equipped with a Black Celcon resin formulated to 1 / o by weight with an antioxidant for example the
Bamox BA, (Swift & Co.), of which the main ally is 2,6-di- (tert-butyl) -p-cresol.
Selon les modes opératoires genéraux décrits dans le brevet US 4 017 030, on prépare des conduits microcapillaires à partir de chacune des résines Celcon et Black Celcon et on remplit les fibres de (Z)-ll-tétradécenal. On expose les conduits microcapillaires à l'action du soleil dans l'Arizona pendant 21 jours. A des intervalles de 7 jours pendant cette période on prélève des conduits microcapillaires dont on détermine la teneur en (Z)-ll-tétradécénal actif. According to the general procedures described in US Pat. No. 4,017,030, microcapillary conduits are prepared from each of the Celcon and Black Celcon resins and the (Z) -11-tetradecenal fibers are filled. The microcapillary ducts are exposed to sunlight in Arizona for 21 days. At intervals of 7 days during this period, microcapillary lines are taken out and the active (Z) -11-tetradecenal content is determined.
