中文摘要：玉米象鼻虫玉米象（Mostchulsky），是贮藏玉米中的一种害虫，损害饲料并导致产毒真菌增殖。用高浓度CO2气调是一种控制玉米象并抑制真菌生长的替代方法。本研究旨在确定玉米象侵扰、籽粒破损及粮食水分对玉米中黄曲霉产生黄曲霉毒素的作用，以及高CO2气调包装对虫害侵扰及黄曲霉毒素产生的影响。研究显示，所测试的高CO2气调包装(90% CO2, 5% O-2 and 5% N-2)阻止了霉菌毒素的产生。
外文摘要：The weevil Sitophilus zeamais (Motschulsky), the maize weevil, is a pest of stored maize that can cause feeding damage and lead to the proliferation of toxigenic fungi. The application of modified atmospheres with a high concentration of CO2 is an alternative method for the control of S. zeamais and the inhibition of fungal growth. The objectives of the study were to determine the effect of S. zeamais infestation, grain damage and grain moisture content on aflatoxin production by Aspergillus flavus on maize, and the impact of high CO2 modified atmosphere packaging on pest infestation and aflatoxin production. Mycotoxin production was only recorded when maize was infested with S. zeamais and had A. flavus inoculum. However, production of mycotoxins was not recorded when the maize was mechanically damaged and stored at 18% moisture content, indicating that the biological activity of the insect was determinant in the production of mycotoxins. The high CO2 modified atmosphere packaging tested (90% CO2, 5% O-2 and 5% N-2) prevented mycotoxin production.
