【背景】柳厚壁叶蜂是一种严重为害柳树的害虫,会造成叶片提早枯黄、脱落,虫瘿成串,叶片扭曲变形,严重影响柳树的生长发育和园林景观效果。【方法】通过体视显微镜观察了柳厚壁叶蜂雌雄成虫、卵、幼虫、蛹及虫瘿的形态特征,并调查了乌鲁木齐市不同区域各种柳树上柳厚壁叶蜂的危害率及空间分布特征。【结果】垂柳和龙爪柳受害最严重,受害株率达到100%;其次是旱柳,受害株率52.63%;该蜂对白柳及馒头柳没有危害。柳树冠不同方向和上、中、下不同部位受害率无显著性差异。每片叶通常有1~3个虫瘿,串珠状分布,每个虫瘿中有1头幼虫,幼虫在枝条上的分布格局为聚集分布。不同区域垂柳受害率调查表明,新疆农业大学柳树枝条受害率最高,达8.65%;其次是新疆大学洪湖,枝条受害率为5.19%;然后依次是儿童公园、西公园、植物园、水上乐园、红山公园、水磨沟公园。【结论与意义】本研究为柳厚壁叶蜂的预防控制提供了依据。
【Background】 The willow thompson is a pest that willfully damage the willow and will cause the leaves to turn yellow and fall off earlier. The insects will be twisted and the leaves will be twisted and distorted, which will seriously affect the growth and development of willow trees and landscape effects. 【Method】 Morphological characteristics of male and female adults, eggs, larvae, pupae, and larvae of the genus Horsetail were observed by stereomicroscope. The hazard rates and spatial distribution characteristics of Salix lanceolata were studied on various willow trees in different regions of Urumqi. 【Result】 Weeping willow and Przewalsla crenata harmed most seriously, with the rate of affected plants reaching 100%; followed by Salix matsudana, with a rate of 52.63%. The bees had no harm to the white willows and the steamed breads. Willow crown different directions and the upper, middle and lower parts of the victimization rate was no significant difference. Each leaf is usually 1 to 3 insects, beaded distribution, each insect has 1 larvae, larvae in the distribution pattern of the distribution of aggregates. The investigation of weeping willow damage rate in different regions showed that the damage rate of willow branches in Xinjiang Agricultural University was the highest (8.65%), followed by that of Honghu in Xinjiang Province, with 5.19% of the damage rate of branches; then followed by Children’s Park, West Park, Botanical Garden, Water Park, Hongshan Park, Shuimogou Park. 【Conclusion and Significance】 This study provided the basis for the prevention and control of Isatis indigotica.
