| 摘 要： | 1985~1989年进行了荔枝蝽,龙眼角颊木虱和龙眼鸡传染龙眼鬼帚病以及荔枝蝽从龙眼到荔枝的传病试验。结果指出:荔枝蝽成虫、幼虫和龙眼角颊木虱成虫均能传染龙眼鬼帚病,传病率分别为18.8-36.7% 40.0-45.0%与23.3-37.9%。试验苗的潜育期,短的为2-3个月,长的约一年。龙眼鸡和对照处理的试验苗均无发病。电镜检查结果表明:在荔枝蝽(成虫)唾液腺细胞内所见的线状病毒粒体,与龙眼鬼帚病叶组织采用超薄切片所观察到的病毒粒体,在形态结构上基本相同,进一步确认介体昆虫传病的可靠性。荔枝蝽成虫,若虫还能将龙眼鬼帚病传到荔枝上,引起与龙眼鬼帚病十分相似的病状。这一结果为揭示荔枝鬼帚病和龙眼鬼帚病之间的密切关系提供了新证据。

| Abstract: | The test of transmission of longan witches' broom disease by insect vectors,was carried out from 1985 to 1989.The results indicated that Tessaratoma papillosa Dtury and Corne genapsylla sinica Yang et Li were the insect vectors of the disease.of the 61 tested plants inoculated with the adults of Tessaratema papillosa and 95 tested plants inoculated with its nymphs,17 and 38 showed symptoms respectively. |
