荔枝蝽(Tessaratoma Papi1llosa)和龙眼木虱(Cornegenapsylla Slnica Yanget Li)都是龙眼树上具有一定飞翔能力的刺吸式口器的害虫。为证实这两种昆虫可能是龙眼鬼帚病的传病介体,我们自1983年以来进行了传病试验。毒源树系具有典型龙眼鬼帚病状的田间病株,供试健苗是从健株龙眼树采的种子,在防虫网室内培育的8个月至三年半的实生苗,以上品种均为“油潭本”。设龙眼木虱成虫、荔枝蝽成虫和若虫三个处 Tessaratoma Papi1llosa and Cornegenapsylla Slnica Yanget Li are pests that have a certain ability to fly on the longan tree. To confirm that these two insects may be the disease mediators of longan ghost broom disease, we have conducted a transmission test since 1983. The source tree is a typical longan ghost broom disease in the field of disease strains for the test Jianmiao is a seed collected from the longan trees, in the insect net indoor nurturing eight months to three and a half years of seedlings, the above varieties are “Oil Tan Ben.” Set longan psylla adult, lychee stink bug adult and nymph three
