近年来,新疆甜瓜感染病毒病(主要是甜瓜花叶病毒)严重,轻病区发病率5—20％,重病区达100％。感病植株座果率低,产量下降,瓜的品质也变劣,商品价值大受影响。 据历年调查,五家渠地区,甜瓜生长期瓜田麦二叉蚜发生量占有翅蚜总量的80.3％,麦长管蚜占15.7％,紫闭蚜占2.85％,其它蚜虫占1.15％。由此看来,新疆甜瓜病毒病的发生可能与麦二叉蚜的关系较大。为此,我们进行了下列方面的调查研究,初步证明麦二叉蚜是传播甜瓜病毒病的介体,采取灭蚜措施可以减轻此病害。
In recent years, Xinjiang melon virus disease (mainly melon mosaic virus) serious, the incidence of mild disease 5-20%, severe disease reached 100%. Sensitive plants with low fruit yield, yield decline, melon quality also worse, greatly affected the value of the commodity. According to the survey over the years, Wujiaqu area, melon growth period Melon Aphid meliloti accounted for 80.3% of the total amount of occurrence, wheat aphid 15.7%, purple aphids accounted for 2.85%, other aphids accounted for 1.15%. Seen in this light, the occurrence of melon virus disease in Xinjiang may have a greater relationship with the wheat aphid. To this end, we conducted the following aspects of the investigation and study, preliminary evidence of wheat aphid is the media for the spread of melon virus mediator, taking aphid measures to alleviate the disease.
