Abstract

Large amounts of wheat streak mosaic virus (WSMV) accumulate in the midgut of its mite vector Eriophyes tulipae reared on virus infected plants. Masses of flexuous rod shaped virus particles persisted in the midgut, without degradation, for at least 5 of the 6--9 day adult life of mites. WSMV particles also were found distributed in the body cavity and in salivary glands of mites suggesting that the virus is "circulative" in E. tulipae. Abacarus hystrix, a nonvector of WSMV, when reared on virus infected plants, occasionally contained a small number of virus particles in its gut only. Extracts of such mites were not infective. Barley stripe mosaic (BSMV)--a rod-shaped virus, was not transmitted by E. tulipae, although a large concentration of virus particles was found in the midgut of mites reared on virus infected plants. Extracts of such mites were infective and the virus particles were retained for several days in the gut of such mites held on virus-free plants. BSMV particles were also found in the body cavity of mites. Possible reasons for E. tulipae being a nonvector of BSMV are discussed.

摘要

大量小麦条纹花叶病毒（WSMV）在以感染病毒的植物为食的叶螨传毒介体郁金香瘿螨的中肠中积累。在螨6至9天的成虫寿命中，至少有5天，大量弯曲的杆状病毒粒子持续存在于中肠中，没有降解。在螨的体腔和唾液腺中也发现了WSMV粒子，这表明该病毒在郁金香瘿螨中是“循环型”的。无网长管蚜，一种WSMV的非传毒介体，在以感染病毒的植物为食时，仅在其肠道中偶尔含有少量病毒粒子。这种螨的提取物没有感染性。大麦条纹花叶病毒（BSMV）——一种杆状病毒，不能由郁金香瘿螨传播，尽管在以感染病毒的植物为食的螨的中肠中发现了大量病毒粒子。这种螨的提取物具有感染性，并且在以无病毒植物为食的螨的肠道中，病毒粒子能保留数天。在螨的体腔中也发现了BSMV粒子。文中讨论了郁金香瘿螨作为BSMV非传毒介体的可能原因。
