番茄黄化卷叶病毒的流行危害引起番茄产量大幅度下降。番茄间作其它作物 ,可减轻媒介昆虫传毒 ,是综合防治番茄黄化卷叶病毒的有效方法之一。番茄间作黄瓜、玉米、菜用大豆、黄秋葵、红薯后对发病情况及白粉虱虫口密度的影响试验结果表明 ,定植 5 8d后 ,病害发生达高峰期 ;白粉虱成虫迁飞高峰在 1月份 ,1月中旬至 2月中旬白粉虱幼虫虫口密度最大 ;定植后 3 7、47、5 8、78d ,不同间作作物上白粉虱幼虫虫口密度有显著或极显著差异 ;黄瓜、菜用大豆是白粉虱偏爱的寄主植物 ;番茄间作菜用大豆、玉米、红薯、黄瓜对番茄黄化卷叶病毒有一定防效
The prevalence of tomato yellow leaf curl virus caused a substantial drop in tomato production. Tomato as intercropping crops, can reduce the transmission of vector insects, is one of the effective ways to comprehensively control tomato yellow leaf roll virus. Effect of Intercropping Cucumber, Corn, Vegetable Soy, Okra and Sweet Potato on Incidence and Population Density of Bemisia tabaci The results showed that the disease peaked at 58 days after planting, and the migratory peak of the whitefly adult was at January 1 The population density of larvae of B. tabaci was the highest from mid-month to mid-February. Significant or very significant differences were observed in larval population density of B. tabaci on different intercrops at 37, 47, 58, 78 days after inoculation; cucumber and vegetable soybean were the preferred ones Of the host plants; tomato intercropping with soybeans, corn, sweet potatoes, cucumber tomato yellow roll virus has some control effect
