项目摘要

There has been much studied on host plant selections and the influence of plant materials to sap suiting by aphids, planthoppers and leafhoppers. First we have taken experiments on host selection behavior of Aphis cractivora on the red and white flowering lablab beans(Dolichos lablab). Rid pigments in the red flowering lablab bean did not disturb sucking from the red colored stem, as we learned from Chinese observation. We discontinued the experiments on A. craccivora at this stage.We then took experiments on feeding preference tests on the green leafhoppers. Four green leafhoppers, Nbohotettix cineticeps, N. nigropictus, N. virescens and N. malayanus distribute from temperate to tropical regions of Asia. N. malayanus prefer Leersia hexandra, a gramineous grass, as host plant than cultivated rice cultivars. All four species colonies were kept in our laboratory on rice seedlings and three Nephotettix well established colonies except for N. malayanus. Host preference tests were carried out using rice cultivars and gramineous grass and found differences on survival rate, growth index and feeding experiments using electric measurement of insect feeding(EMIF) were carried out. Test results indicated presence of feeding stimulant in "nihonbare" for three Nephotettix spp. and feeding inhibitor in IR42 for N. cincticeps and N. nigropictus. L. hexandra contains feeding inhibitor for N. virescens. EMIF were first carried out on plant seedings and feeding tests were expanded using with plant extracts through artificial membrane, parafilm. Identification of chemical factors on preference by the green leafhoppers are now being investigated in extracts from rice cultivars and gramineous plants.

关于蚜虫、稻飞虱和叶蝉对寄主植物的选择以及植物材料对它们汁液适应性的影响，已有大量的研究。首先，我们进行了豆蚜对红扁豆和白色扁豆寄主选择行为的试验。正如我们从中国人的观察中了解到的那样，红色开花的扁豆中的色素并没有妨碍红色茎的吮吸。我们停止了对A的实验。在此阶段，我们对绿色叶蝉进行了摄食偏好试验。本文报道了四种绿色叶蝉，即灰叶蝉Nbohotettix cineticeps、灰叶蝉N. nigropictus、黑刺拟步行虫N. virescens和N.马来人分布于亚洲的温带至热带地区。N. Malayanus喜欢Leersia hexandra，一种禾本科草作为寄主植物比栽培水稻品种。所有四个物种的菌落都保存在我们的实验室中的水稻幼苗上，并且除了N.马来西亚利用水稻品种和禾本科牧草进行了寄主选择性试验，发现存活率和生长指数的差异，并利用昆虫取食电测量（EMIF）进行了摄食试验。试验结果表明，“nihonbare”中存在三种黑尾叶蝉属的摄食刺激物。IR 42对N. cincticeps和N.黑刺象。L. hexandra含有N.绿色的首次在植物性小球藻上进行了EMIF试验，并利用植物提取液通过人工膜、石蜡膜进行了扩大饲养试验。鉴定化学因子的喜好绿色叶蝉目前正在调查的提取物从水稻品种和禾本科植物。
