摘要: 采用体视镜分别测定无翅型和有翅型艾小长管蚜(Macrosiphoniella yomogicola)1龄、2龄、3龄、4龄若蚜和成蚜的体长、体宽、头宽、触角长、腹管长、尾片长、后足胫节长7个形态指标,并进行相关分析和回归分析,明确艾小长管蚜的龄期特征,为艾蚜虫的综合防治提供技术支撑。结果表明,不同龄期艾小长管蚜的形态指标存在显著差异,且形态指标间呈极显著正相关;回归分析表明,无翅型和有翅型艾小长管蚜的龄期与头宽、触角长、腹管长和后足胫节长呈线性极显著相关,而与体长、体宽和尾片长无线性显著相关;进一步研究表明,无翅型和有翅型艾小长管蚜的腹管长在各龄期间无重叠,后足胫节长在1龄和2龄若蚜间无重叠,触角长在1龄、2龄和3龄若蚜间无重叠,而体长、体宽、头宽和尾片长在各龄期间均重叠。综上,选择腹管长作为艾小长管蚜龄期鉴定的主要指标,触角长和后足胫节长作为艾小长管蚜龄期鉴定的辅助指标。

Abstract: The morphologic indicators of body length,body width,head width,antenna length,cornicle length,cauda length,and hind tibia length for Macrosiphoniella yomogicola at 1st,2nd,3rd,4th instars and adult were measured by stereoscopy,the data were analyzed by correlation analysis and regression analysis,and then the characteristics of Macrosiphoniella yomogicola at different instars were identified,to lay technical support for aphid integrated control in Artemisia argyi of Chinese medicinal materials.The results showed that morphologic indicators of Macrosiphoniella yomogicola had significant differences at different instars,and showed significantly positive correlation among them. Regression analysis indicated that head width,antenna length,cornicle length and hind tibia length of Macrosiphoniella yomogicola were linearly positively related to instars,but body length,body width and cauda length showed no linear significant correlation with instar. Further data analysis showed that cornicle length of wingless and winged Macrosiphoniella yomogicola displayed no overlap between adjacent instars,hind tibia length displayed no overlap between 1st and 2nd instar nymphs,antenna length displayed no overlap between 1st,2nd and 3rd instar nymphs,but body length,body width,head width and cauda length had overlap between adjacent instars. In conclusion,cornicle length can be screened as a main indicator for identification of instars of Macrosiphoniella yomogicola,and antennae length and hind tibia length can be as assistant indexes.
