不同大米包装材料防害虫钻蛀性研究

Study on the Resistance of Different Rice Packaging Materials Against Insect Pests

在28℃、75%±5%相对湿度条件下,进行四种储粮害虫赤拟谷盗、锈赤扁谷盗、谷蠹、米象对七种常见大米包装材料的钻蛀能力的研究。结果表明,双面覆膜打孔包装与单面覆膜打孔包装抗虫性差,对不同虫态的四种储粮害虫均无防御作用。双面覆膜不打孔包装、双面覆膜带内衬包装、真空包装和充气包装能够防御四种害虫钻蛀。

This study investigated the boring ability of four stored grain insects including Tribolium castaneum,Cryptolestes ferrugineus,Rhizopertha dominica,and Sitophilusoryzae to seven common rice packaging materials at the temperature of 28℃and relative humidity of 75%±5%.The results showed that the double-sided coated perforated packaging material and the single-sided film perforated packaging material exhibited poor insect resistance and had no defense against the four insects at different life stages.However,the double-sided coated non-perforated packaging material,the double-sided coated packaging material with lining,the vacuum PE packaging material,and the inflatable PE packaging material can prevent the boring of the four insects.
