摘要:
 松沫蝉是同翅目(Homoptera)沫蝉科(Cercopidae)的一种刺吸式害虫，危害多种松树。若虫隐藏在排出的泡沫中，不易直接观察，采用人工饲养观察若虫蜕皮的方法来划分龄期有很大难度。本研究采集松沫蝉若虫957头、成虫116头，测量若虫的头壳宽度，通过头壳宽度的频次分布划分若虫龄数和龄期。结果表明，松沫蝉若虫可分为5龄，1~5龄头壳宽度均值分别为0.60±0.00、0.83±0.01、1.12±0.01、1.61±0.01 mm与2.20±0.12 mm；不同龄若虫的头壳宽度均值差异显著。Crosby指数支持5龄的划分，生长模型拟合结果表明头壳宽度与不同龄期极相关。1~5龄若虫龄期值分别为3.55、13.49、9.12、16.22 d与18.93 d，若虫龄期为61.31 d。松沫蝉若虫龄数和龄期的划分，可以为林间快速判断其发育状态提供依据。
Abstract:
Aphrophora flavipes (Homoptera: Cercopidae) is a sucking mouthparts pest,is harmful to many pine species.The nymph of A.flavipes is not easily found because it hides in the excreted froth by itself.So it is very difficult to determine its instars using the method of observing its ecdysis by artificial feeding the nymph.In this study,957 nymphs and 116 adult were collected,the head carapace widths of nymph were measured to divide instars by frequency distribution of its head carapace widths.The results showed that the nymph of A.flavipes was divided into 5 instars,the mean values of the head carapace widths of 5 instars were 0.60±0.00 mm,0.83±0.01 mm,1.12±0.01 mm,1.61±0.01 mm,and 2.20±0.12 mm,respectively with significant differences.The Crosby index supported the conclusion of dividing 5 instars and the fitting result of growth model showed that the head carapace widths were very significantly correlated with its instars.The average stadia from 1st to 5th nymph based on the median value of samples were 3.55,13.49,9.12,16.22,and 18.93 d respectively and the whole stadia of nymph was 61.31 d.The result of dividing the A.flavipes nymph into 5 instars was dependably,it could provide a basis for distinguishing its instars in forestry quickly.
