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。
From 1985 to 1989, litchi stinkbugs, longhorn psyllid louse and longan gondolas were introduced, and the pathogenicity test of litchi stinkbug from longan to litchi was conducted. The results showed that adults, larvae and adults of Longyinopus longicollis all could infect longan ghost broom disease, with the prevalence rates of 18.8-36.7% 40.0-45.0% and 23.3-37.9%, respectively. Potential incubation of test seedlings, short for 2-3 months, about a year long. There was no disease in the experimental seedlings treated with longan and control. Electron microscopy results showed that the virions observed in the salivary gland cells of litchi stink bug (adult) were similar to the virions observed with the ultrathin sections of longan ghost broom leaves, and their morphological structures were basically the same Confirm the reliability of mediator insects. Lychee stink bug adults, nymphs can spread longan ghost broom disease on the lychee, causing very similar symptoms with the longan ghost broom disease. This result provides new evidence for revealing the close relationship between litchi ghost broom and longan ghost broom disease.
