摘要
对我国不同地区和不同植物上所采集的棉褐带卷蛾3个属群进行形态分类研究,发现茶叶、棉花上的2个属群幼虫上颚第5齿、蛹下唇基毛、雄虫前翅基斑、中带、雄性爪型突和雌性囊导管长度等与苹果、桃树上的属群均存在较大差异。结合性信息素、杂交等研究,认为我国的棉褐带卷蛾已发生了种下分化,应分为两个亚种,即为害苹果、桃树的种为苹褐带卷蛾AdoxophyesoranabeijingensisZhouetFu,而在棉花、茶树上为害的种是棉褐带卷蛾AdoxophyesoranaoranaFischervonRoslerstamm。
Summer fruit tortrix Adoxophyes orana Fischer von Roslerstamm, a polyphagous pest of great economic importance to crops and forest in China and all over the world, has been studied recently. Four strains of the trotrix collected on apple and peach tree in the northern China and on cotton and tea tree in southern China are investigated. We have found some morphological differences between two groups. These facts strongly suggest that differential speciation of the tortrix Adoxophyes orana has occured. Therefore, the tortrix fed on apple and peach in north has been named as Adoxophyes orana beijingensis Zhou et Fu(subsp.nov.) and the tortrix fed on cotton and tea in south of China as Adoxophyes orana orana Fischer von Roslerstamm. Followed is the summary table about the main different characters of these two subspecies. Table 1. Main difference characters of the two subspecies Species Larva Pupa AdultGenitaliaAdoxophyes orana beijingensis Zhou et Fu with five sharpen tooth on mandible and round dots on anterior region of anal plate three pairs of satea on clypeus smaller basal patch and a broken median fascia on malefore wing uncus width 0.22-0.24mm ductus bursae length 2.28mmAdoxophyes orana orana Fischer von Roslerstamm the fifth teeth blunt and no round dots on anal plate two pairs of satea on clypeus larger basal pa tch and an unbro ken median fascia on male forewing uncus width 0.16-0.19mm ductus bursae length 2.90-3.00mm
