红铃虫是我省棉花生产上的主要害虫,各地在测报方面积累了多年的观察资料,但由于以往没有全省统一的标准,以致这些资料无法进行综合分析和利用。为此,我们在全国植保总站的指导下,用了两年的时间,分析了6个县站共76年次的资料。以一类田系统调查的百株卵量为主要依据,进行了红铃虫测报资料统计标准的研究。提出了将我省红铃虫的发生为害分为丘陵早发区和平原洲地迟发区两大类型。并分类型制订出划分世代、发生期、发生程度和为害损失的统计标准。为实现红铃虫测报规范化和标准化提供了依据。一、全省应划分为丘陵早发区和平原洲地迟发区无论从发生期或发生量来看,红铃虫
Red bollworm is a major insect pest on cotton production in our province. Various observational data have accumulated in the area of measuring and reporting for many years. However, since there was no unified standard in the province in the past, these data could not be analyzed and used comprehensively. Therefore, under the guidance of the National Plant Protection Agency, we spent two years analyzing the data of 76 counties in 6 county stations. Based on the data of one hundred ova collected from a field system, the statistical standards of red bollworm data were studied. It is proposed that the occurrence of red bellworms in our province be divided into two types: early onset area in hilly area and later developed area in plains area. And formulates the statistical standards for dividing generations, occurrences, occurrences and damages. In order to achieve the standardization and standardization of Red Bell pest forecast provided the basis. First, the province should be divided into hilly areas and the late plains of the late onset zone no matter from the occurrence or occurrence point of view,
