| 中文摘要: |
| 黑胫腮扁叶蜂(Cephalcia nigrotibialis Wei)以雌虫为模式标本, 描述于我国陕西(周至)和河南(内乡)。2009年在北京延庆发现它是油松上一种新的重要害虫，1年1代, 以老熟幼虫在土室中越冬, 越冬虫口密度平均达20.7头/m2。6月初开始化蛹, 6月下旬出现成虫; 成虫产卵于2年生的松针上, 幼虫在小枝上做丝质的巢, 咬断松针基部后取食, 为害盛期为8-9月。色带诱集试验表明, 5种色带均可诱到成虫, 不同颜色之间差异不显著。目前在延庆将红色胶带用于黑胫腮扁叶蜂的防治。本文对各虫态进行了描述, 并提供了彩色图片, 讨论了该虫的分布特点和成灾原因。 |
| 英文摘要: |
| The web-spinning sawfly Cephalcia nigrotibialis Wei was previously recorded from Shaanxi and Henan Provinces. It was found as a new insect pest on the Chinese red pine (Pinus tabulaeformis) in Yanqing County, Beijing. It has one generation per year and overwinters as matured larva in soil cell, with average population of 20.7 larvae/m2 about 3 cm under the soil. The overwintered larvae begin to pupate at the beginning of June and adults emerge at the last 10-days of June. The female adults lay eggs on the needle of the biennial branch. The larvae cut down the pine needle before eating with silk nest along the branch. The infestation peak is in August and September. The colored sticky traps experiments show that adults come to all 5 colors (red, blue, yellow, white, and black) without significant difference among them. Now the red sticky trap has been in C. nigrotibialis control in Yanqing County. The paper described morphology of four stages, provided with color pictures, and discussed its distribution and causes of heavy infestation. |
