Description
Dispositivo para atraer insectos.Device to attract insects.
La presente invención se refiere a un dispositivo para la descarga sostenida o controlada de una formulación, tal como un semioquímico, por ejemplo una feromona o similar.The present invention relates to a device for sustained or controlled discharge of a formulation, such as a semi-chemical, for example a pheromone or Similary.
Muchos de los dispositivos empleados hoy día como portadores para la descarga sostenida de semioquímicos de insectos, tales como atrayentes, feromonas o similares, incluyen una mezcla del producto químico que atrae a los insectos y plásticos (incluso PVC). Para determinados atrayentes el polímero preferido ha sido el PVC porque da la longevidad requerida al producto. Aunque este sistema funciona bien para la descarga sostenida del producto atraeinsectos, el PVC se considera un problema porque este producto se deja en el campo al final de la temporada. Por lo tanto, los años de uso de un dispositivo basado en el PVC dan por
\hbox{resultado la acumulación de plástico
incorporado en la tierra.} Many of the devices used today as carriers for the sustained discharge of insect semiochemicals, such as attractants, pheromones or the like, include a mixture of the chemical that attracts insects and plastics (including PVC). For certain attractants the preferred polymer has been PVC because it gives the longevity required of the product. Although this system works well for the sustained discharge of the product through insects, PVC is considered a problem because this product is left in the field at the end of the season. Therefore, the years of use of a PVC-based device give \ hbox {result the accumulation of plastic
incorporated into the earth.}
Por consiguiente un objeto de la presente invención es solucionar algunas desventajas, al menos, de las señaladas arriba.Therefore an object of the present invention is to solve some disadvantages at least of the noted above.
Otro objeto más de la presente invención es aportar un dispositivo para la descarga sostenida de un atraeinsectos.Another object of the present invention is provide a device for the sustained discharge of a attracts insects.
Por consiguiente, según un primer aspecto de la presente invención se aporta un dispositivo sustancialmente biodegradable para la descarga sostenida de un atraeinsectos, el dispositivo comprendiendo una combinación de:Therefore, according to a first aspect of the present invention a substantially device is provided biodegradable for the sustained discharge of an attractant, the device comprising a combination of:
un polímero sustancialmente biodegradable o bioerosionable, o un polímero que es bioerosionable cuando está contenido en la combinación;a substantially biodegradable polymer or bioerodible, or a polymer that is bioerodible when it is content in the combination;
un material celulósico de carga; ya cellulosic filler material; Y
un material que afecta a los insectos.A material that affects insects.
El polímero puede ser cualquier polímero conocido en el campo de los plásticos que sean sustancialmente biodegradables, bioerosionables o sustancialmente biodegradables o bioerosionables cuando estén incluidos en la combinación. Sin embargo los polímeros basados en el etilenvinilacetato (EVA) han demostrado que aportan sustratos útiles al ser sustancialmente inertes y que no contienen cualquier compuesto nocivo pero el EVA por sí solo no sería sustancialmente bioerosionable; es la combinación del EVA con el material celulósico de carga la que hace que el dispositivo sea sustancialmente bioerosionable. Es provechoso que el material celulósico absorbe la feromona y, de este modo, se consigue una velocidad más lenta de descarga que con el material polimérico solo.The polymer can be any polymer. known in the field of plastics that are substantially biodegradable, bioerodible or substantially biodegradable or bioerodible when included in the combination. Without However polymers based on ethylene vinyl acetate (EVA) have shown to provide useful substrates by being substantially inert and do not contain any harmful compounds but the EVA by itself it would not be substantially bioerodible; is the combination of the EVA with the cellulosic loading material which makes that the device is substantially bioerodible. Is helpful that the cellulosic material absorbs the pheromone and, of this way, a slower download speed is achieved than with the polymeric material alone.
El material celulósico puede ser la misma celulosa, hemicelulosa, una fibra de madera, madera en polvo, viruta de madera, serrín, almidón, lignina o similares.The cellulosic material can be the same cellulose, hemicellulose, a wood fiber, wood powder, wood chip, sawdust, starch, lignin or the like.
El material que afecta a los insectos puede ser un semioquímico o similar. Este semioquímico puede incluir atrayentes, repelentes, feromonas y cairomonas (los cuales benefician al receptor en detrimento del emisor).The material that affects insects can be a semiochemical or similar. This semiochemical may include attractants, repellents, pheromones and cairomonas (which benefit the recipient to the detriment of the issuer).
Una mezcla de feromona preferida en particular es Z-11-16:AI/Z-9-16:AI/Z-13-18:AI cuando el insecto al que hay que afectar es el perforador del tallo del arroz. De manera muy útil, el dispositivo según la presente invención afectará de forma adversa a la indicación navigacional del insecto macho perforador del tallo del arroz, rompiendo de este modo las pautas de apareamiento. Sin embargo las feromonas adecuadas para otras plagas insectiles pueden incluir (Z, E) (Z, Z)-7,11-16:Ac (Gusano de cápsula rosa), Z, E-7,9-12:Ac (Lobesia botrana), E,E-8,10-12:01 (polilla del bacalao pequeño), E-5-10:Ac/E-5-10:01 (Anarsia lineatella) o E,Z-2,13-18:Ac/E,Z-3,13-18:Ac (Zeuzera pyrina).A particular preferred pheromone mixture is Z-11-16: AI / Z-9-16: AI / Z-13-18: AI when the insect to be affected is the rice stem borer. Very usefully, the device according to the present invention will adversely affect the navigational indication of the male rice stem borer insect, thereby breaking the pairing patterns. However, pheromones suitable for other insect pests may include (Z, E) (Z, Z) -7.11-16: Ac (Pink Capsule Worm), Z, E-7.9-12: Ac ( Lobesia botrana ), E, E-8,10-12: 01 (small cod moth), E-5-10: Ac / E-5-10: 01 ( Anarsia lineatella ) or E, Z-2,13-18: Ac / E, Z-3,13-18: Ac ( Zeuzera pyrina ).
El dispositivo comprende típicamente el material celulósico y el polímero biodegradable o bioerosionable en una cantidad combinada en el intervalo de 75% a 95% en peso del dispositivo. Una cantidad preferida en particular está dentro del intervalo del 83% al 91% en peso del dispositivo.The device typically comprises the material cellulosic and biodegradable or bioerodible polymer in a combined amount in the range of 75% to 95% by weight of the device. A particular preferred amount is within the range from 83% to 91% by weight of the device.

En el campo, la formulación estándar, descarga el 75% de su feromona durante un tiempo de 150 días (medidos de muestras recogidas en el campo en 2002). En un estudio más antiguo, en 1994, (ver la figura 2) la formulación estándar descargó aproximadamente el 50% de su feromona durante un tiempo de 2 meses y medio cubriendo la mayor de la temporada del arroz.In the field, the standard formulation, download 75% of its pheromone for a period of 150 days (measured from samples collected in the field in 2002). In an older study, in 1994, (see figure 2) the standard formulation downloaded approximately 50% of your pheromone for a period of 2 months and a half covering the largest of the rice season.
Los resultados indican que la formulación
estándar está descargando con más lentitud que la requerida y que
una cantidad sustancial de la feromona está todavía en el polímero
al final de la temporada a mediados de septiem-
bre.The results indicate that the standard formulation is discharging more slowly than is required and that a substantial amount of the pheromone is still in the polymer at the end of the season in mid-September.
bre.
Ambos tipos de formulación parecen que descargan con muchísima lentitud en condiciones experimentales con tan solo aprox. del 35% del Z-029 (Z11-16:A1) perdido del polímero de madera y aprox. del 25% del Selibate estándar durante un plazo de 115 días. El área de descarga tiene una oscilación de la temperatura diaria desde aprox. 15°C hasta 30°C. Esto es más frío pero no enormemente diferente de las condiciones de temperatura ambiental que se experimentan en España. La diferencia principal es la ausencia de radiación solar directa en las pruebas en laboratorio. Esto calentaría esencialmente los dispositivos de Selibate negro y aumentaría la velocidad de descarga. El resultado neto es que los resultados obtenidos son puramente comparativos y tienen relación poca con los productos que se espera de la duración en el campo.Both types of formulation seem to download very slowly in experimental conditions with just approx. 35% of Z-029 (Z11-16: A1) lost of wood polymer and approx. 25% of the standard Selibate for a period of 115 days. The area discharge has a daily temperature swing from approx. 15 ° C to 30 ° C. This is colder but not hugely different from the ambient temperature conditions that They experience in Spain. The main difference is the absence of direct solar radiation in laboratory tests. This would essentially heat the black Selibate devices and It would increase download speed. The net result is that results obtained are purely comparative and have a relationship little with the expected products of the duration in the countryside.
El ensayo demuestra que la nueva formulación
basada en la celulosa es más rápida en la descarga que la de
control de Selibate estándar. Dado que una gran parte de feromona
permanece en la formulación estándar al final de la temporada, el
dispositivo según la presente invención puede tener la ventaja de
una velocidad de descarga más
rápida.The test demonstrates that the new cellulose-based formulation is faster in discharge than the standard Selibate control. Since a large part of pheromone remains in the standard formulation at the end of the season, the device according to the present invention may have the advantage of a more rapid discharge rate.

La calidad de la extrusión está afectada notablemente por la temperatura de la extrusión, Enfriando la parte superior se consiguió un perfil mejor. Sin embargo cuando se enfrió demasiado la extrusión se paró de manera que, en este caso, una temperatura de compromiso, de menos de 100°C parece apropiada.The quality of the extrusion is affected notably by the extrusion temperature, Cooling the part superior got a better profile. However when it cooled too much extrusion stopped so that, in this case, a temperature of compromise, less than 100 ° C seems appropriate.

Extrusión de un perfil de 3,5 mm x 25 mm.Extrusion of a 3.5 mm x 25 mm profile.
Se comprobó que era sumamente difícil extruir la formulación si primero se absorbía la feromona dentro de la madera en polvo o dentro de la mezcla de polímero y madera antes de la extrusión. Este siguió siendo el caso incluso si de dejaba que el material reposase durante mucho tiempo y que la feromona se absorbiera dentro del polímero. Con el fin de solucionar este problema se ha hallado que primero se absorbe la feromona dentro del polímero y luego se añade virutas de madera y aceite. Como consecuencia se necesitó un poco más de aceite para lubricar la madera en polvo.It was found that it was extremely difficult to extrude the formulation if pheromone was first absorbed into the wood powder or within the mixture of polymer and wood before the extrusion. This remained the case even if he let the material rests for a long time and the pheromone is absorbed into the polymer. In order to solve this problem has been found that pheromone is first absorbed into of the polymer and then wood chips and oil are added. How consequently it took a little more oil to lubricate the wood powder
