棉红铃虫是本省棉花中、后期的主要害虫。在开展红铃虫发生量预报、制定全省棉虫综防决策时,如何正确估计该虫的为害损失程度,确定合理的棉花受害虫口允许密度,提高测报和防治经济效益,是我省当前急待解决的问题。为此,自1982年3月起,我们按照农牧渔业部农作物病虫测报站的要求,在省测报站主持下,组织荆州地区和枝江、广济、当阳县等四个植保站,进行了棉红铃虫危害损失测定及防治指标研究. Cotton bollworm is the province of cotton, the main pest in the late. In carrying out the forecast of the occurrence of the pink bollworm and formulating the province’s cotton comprehensive prevention and control decision, how to correctly estimate the damage degree of the insect, to determine the reasonable allowable density of the cotton bollworm population, to improve the reporting and prevention and control of economic benefits Problem to be solved. To this end, since March 1982, we have organized four plant protection stations in Jingzhou Prefecture, Zhijiang County, Guangji County and Dangyang County in accordance with the requirements of the Crop Disease and Pest Report Station of the Ministry of Agriculture, Animal Husbandry and Fisheries. Study on Hazard Loss and Control Index of Cotton.

“最近老是睡不好,真烦人。”现代社会,不少人都为失眠所困。科学家们也一直在孜孜不倦寻找扰乱我们睡眠的“罪魁祸首”。最新的研究结果是:我们的身体里,有一种和睡眠相关的基因,如果这种基因缺失,就会产生睡眠障碍。  这则消息让人没法淡定了:“失眠居然是因为基因出了问题,那还能治吗?”“既然是基因的问题,那会不会遗传啊?我的老爸老妈经常失眠,那我以后是不是也会失眠啊?”  先别急,来听听研究者是怎么说的。
