Abstract

L'invention concerne un tube de résine synthétique, lequel tube est conçu de telle sorte que le coût de fabrication peut être réduit et de telle sorte que des organismes nuisibles peuvent être régulés sur l'intérieur et l'extérieur du tube. Un tube (1) est constitué par une résine synthétique et comporte une paroi de tube ayant une couche externe (2), une couche interne (3), et une couche intermédiaire (4). Seules la couche externe (2) et la couche interne (3) du tube (1), à l'exclusion de la couche intermédiaire (4) du tube (1), comprennent des couches de régulation (par exemple, des couches de régulation de termites pour lutter contre les termites) pour lutter contre des organismes nuisibles. La région des couches de contrôle du tube (1), qui augmente le coût, peut être réduite en raison du fait que la couche intermédiaire (4) n'est pas une couche de régulation.
