据了解,我国有记载的棉花害虫有300多种,其中常发性害虫有30多种,为害严重的有棉铃虫、盲蝽象、烟粉虱、棉蚜虫、红蜘蛛等。据统计,我国棉花生产每年因害虫造成的损失有10%~30%,严重时可超过50%。近年来,转基因抗虫棉的应用,使棉铃虫的发生为害有所缓解。但一些次要害虫却逐年增加并成为主要害虫,特别是受栽培制度的变革、生态环境恶化、气候变化、外来生物入侵和棉农滥用化学农药等因素的影响,主要虫害持续严重。那么,我国昆虫科学家将如何应对这种状况,确保我国棉花产业的稳定发展呢?近日,记者采访了中国
It is understood that there are more than 300 kinds of cotton pests recorded in our country, of which there are more than 30 kinds of common pests. The most serious pests are cotton bollworm, black bugs, whitefly, cotton aphids and red spiders. According to statistics, the annual loss caused by pests in China’s cotton production is 10% to 30% and in severe cases it can exceed 50%. In recent years, the application of transgenic cotton has made the damage of cotton bollworm eased. However, some minor pests have increased year by year and become major pests. In particular, the main pests continue to be seriously affected by factors such as changes in the cultivation system, deterioration of the ecological environment, climate change, invasive alien species and chemical abuse by cotton farmers. So, how will our insect scientists cope with this situation to ensure the stable development of China’s cotton industry? Recently, the reporter interviewed China
