Experiments were conducted to determine the settling behavior, survival, and reproduction of the beet leafhopper, Circulifer tenellus (Baker), when maintained on selected host plants. This leafhopper was recently identified in the Columbia Basin of Washington and Oregon as the probable vector of the beet leafhopper-transmitted virescence agent phytoplasma, causal agent of several vegetable crop diseases, including potato purple top. Plants selected for study were sugar beet, Beta vulgaris L.; radish, Raphanus sativus L.; dry bean, Phaseolus vulgaris L.; potato, Solanum tuberosum L.; carrot, Daucus carota L.; and tomato, Lycopersicon esculentum Mill. Leafhopper adults were confined on caged plants, and settling behavior was observed during a 72-h period and survival was monitored for 40 d. Also, oviposition and nymphal production were investigated by maintaining leafhoppers for approximately 90 d on each of the selected plants. Sixty to 100% of leafhoppers settled on all studied plants during the first 5 h, but settling on bean and tomato declined sharply thereafter. Leafhopper mortality was very high on bean and tomato, with 95 and 65% of the leafhoppers, respectively, dying in about a week. In contrast, 77, 90, and 95% of leafhoppers maintained on potato, sugar beet, and radish, respectively, survived until the end of the 40-d experimental period. Beet leafhopper oviposition and nymphal production and development only occurred on sugar beet, radish, and potato; reproduction was lower on potato.
开展了实验，以确定甜菜叶蝉（Circulifer tenellus (Baker)）在选定寄主植物上饲养时的栖息行为、存活情况和繁殖能力。这种叶蝉最近在华盛顿州和俄勒冈州的哥伦比亚盆地被确认为可能传播甜菜叶蝉传播性绿变病原体植原体的媒介，该病原体是包括马铃薯紫顶病在内的几种蔬菜作物病害的致病因子。选择用于研究的植物有甜菜（Beta vulgaris L.）、萝卜（Raphanus sativus L.）、干豆（Phaseolus vulgaris L.）、马铃薯（Solanum tuberosum L.）、胡萝卜（Daucus carota L.）和番茄（Lycopersicon esculentum Mill.）。将叶蝉成虫限制在笼养植物上，在72小时内观察其栖息行为，并监测40天的存活情况。此外，通过在每种选定植物上饲养叶蝉约90天，研究其产卵和若虫产生情况。在最初的5小时内，60%至100%的叶蝉栖息在所有研究植物上，但此后在豆类和番茄上的栖息率急剧下降。叶蝉在豆类和番茄上的死亡率非常高，分别约有95%和65%的叶蝉在一周内死亡。相比之下，分别在马铃薯、甜菜和萝卜上饲养的叶蝉，有77%、90%和95%存活到40天实验期结束。甜菜叶蝉的产卵、若虫产生和发育仅发生在甜菜、萝卜和马铃薯上；在马铃薯上的繁殖率较低。
