摘要：
The present invention provides a device for assessing the resistance of laminate materials against the attack of warehouse insects-plagues, said device is operated under controlled conditions so that obtaining a highly sensitive and accurate response. This device is particularly formed by a container for storing, under a controlled atmospheric pressure, humidity and gas concentration, a predetermined amount of cereal grains and plague insects of cereal grains a mechanism for controlling the pressure is communicated with the container for creating and maintaining a pressure differential within said container, the differential being measured between the pressure inside and outside the container a mechanism for controlling the gases is located inside the container for maintaining a predetermined concentration of gases, an assessing unit being coupled to the end portion of the controller, and consisting in a first and second metal ring where at least a laminate sample is located between said rings the remaining end portion of the unit is connected to: a reservoir base for supporting the container and the ring with at least a laminated sample brought into contact with the cereal grains of the container, and temporarily confining the plague insects that penetrate the laminated sample for being counted.La presente solicitud provee un dispositivo para evaluar la resistencia contra el ataque de insectos-plagas de almacén de materiales laminados, dicho dispositivo opera en condiciones controladas de tal forma que se obtiene una respuesta de alta sensibilidad y precisión. Particularmente, dicho dispositivo esta conformado por un contenedor para almacenar, bajo presión atmosférica, humedad, y concentración de gases controlada, una determinada cantidad de granos de cereales e insectos plaga de granos cereales un mecanismo controlador de presión en comunicación con el contenedor para crear y mantener un diferencial de presión dentro de dicho contenedor, dicho diferencial medido e
