| 摘 要： | 试验结果指出:棉蚜Aphis gossypii Glov.是罗汉果Siraitia grosvneri(Swingle)Jeffrey.疱叶丛枝病的媒介昆虫。有翅蚜和无翅蚜都有传毒力:传毒习性的研究结果指出:每苗接虫三头或使之吸食15分钟以上,就足以使健苗发病。 由于媒介昆虫自然传播的主导因素.所以理论上和实践上都指出与病区隔离种植实生苗,是解决罗汉果疱叶丛枝病的根本措施之一。

A PRELIMINARY STUDY ON INSECT VECTOR (APHIDES)AND CONTROL OF BLISTERED LEAVES WITCHES' BROOM DISEASE OF LUOHANGUO |

| Abstract: | The results of extensive transmissive experiments of MLO on Luohanguo Siraitia grosvenon (Swingle) Jeffrey] indicated that aphides, (Aphis gossypii Glov.), the winged and wingless aphides, were the vector of blistered leaves witches' broom disease.These evidences have been confirmed by observation, the wingless aphides are rather inactive and the spreading of MLO over Luohanguo depends upon the number and activity of winged aphides.Experiment in screen cages indicated the Aphis gossyphii Glov was able to transmit MLO in feeding period of no less than 15 minutes by inoculating seedling with three aphides. These can cause affection to the healthy seedlings.Since insects are the main factor to transmit disease in nature, one of the fundamental methods to solve this problem, theoretically and practically, should be the isolating plantation of Luohanguo seedlings from those of affected. |
