全国农业技术推广服务中心近日称,据各棉区病虫害测报区域站监测,今年一代棉铃虫总残虫量大部棉区同比偏高,山东、山西、安徽等省份高于常年;6月份气象条件对黄河流域和新疆部分地区棉铃虫发生有利,预计今年二代棉铃虫在黄河流域、新疆大部为中等发生,长江流域为偏轻发生。但由于各地Bt棉种植面积比率大,棉田幼虫量较低,对棉花的危害较轻,花生、大豆、蔬菜、玉米等其他作物的危害将呈加重 According to the National Agricultural Technology Extension Service Center recently, according to the monitoring of the pest and disease detection regional stations in the cotton area, most cotton bollworms in this year’s generation have the highest year-on-year total cotton swallows, while the provinces such as Shandong, Shanxi and Anhui are higher than the normal ones. The meteorological conditions Helicoverpa armigera is favorable for the Yellow River Basin and parts of Xinjiang. It is estimated that the second-generation cotton bollworm in this year will occur moderately in the Yellow River Basin and Xinjiang, while the Yangtze River Basin will be slightly overweight. However, due to the large area around Bt cotton acreage, the low amount of cotton larvae, less harmful to cotton, peanuts, soybeans, vegetables, corn and other crops will be increased the hazard
