The results of infestation by maize weevil, Sitophilus zeamais (Coleoptera, Curculionidae), in different packaging filled with pasta are presented in this research. Three different types of packaging were used, that is, two paper tubes (one novel, laminated with bio‐based polyethylene and one without lamination) and commercial polypropylene, pillow pouch packaging. Material properties such as grammage, thickness, surface analysis, moisture and water resistance, tensile and compressive strength were analysed. Improved compressive strength, moisture and water resistance were detected at the bio‐polyethylene laminated tube packaging (approx. 30%), compared to the non‐laminated sample. The obtained results demonstrated that adult maize weevils revealed significant preferences to enter the pasta packages through the already existing holes which were in the polypropylene packaging, while no infestation was observed inside the packages at the paper tube packaging. The study revealed that the shape and construction, for example, tube packaging with an innovative bio‐polyethylene film, are very effective regarding insect infestation and mechanical overloads.

包装具有抗玉米赤潮菌（Sitophilus zeamais）侵染的能力
玉米象鼻虫（Sitophilus zeamais）侵染的结果（鞘翅目，Curculionidae），在不同的包装中充满了意大利面。使用了三种不同类型的包装，即两根纸管（一根新颖的管，用生物基聚乙烯层压，另一根未层压）和商用聚丙烯枕套包装。分析了材料性能，如克重，厚度，表面分析，耐湿水性，拉伸强度和抗压强度。与未层压样品相比，在生物聚乙烯层压管包装中检测到了更高的抗压强度，耐湿性和耐水性（约30％）。获得的结果表明，成年玉米象鼻虫显示出明显的偏好，希望通过聚丙烯包装中已经存在的孔进入面食包装，而在纸管包装的包装内没有发现侵扰。研究表明，形状和结构，例如采用创新的生物聚乙烯薄膜的管包装，对于昆虫侵扰和机械过载非常有效。
