粉虱是一个昆虫类群，包括多个物种和生物型，能够通过韧皮部取食、病毒传播和促进真菌定殖来影响作物。这些害虫分布在世界各地。在位于热带的哥斯达黎加，最成问题的粉虱是烟粉虱生物型B和温室粉虱。2009年9月，在该国首都圣何塞西北部的阿尔法罗鲁伊斯地区的两个温室进行了调查，作为更大努力的一部分，以确定在这个重要的农业地区粉虱的物种和种族的发生。此外，分析昆虫样品以确定番茄褪绿病毒（ToCV）的存在，这是一种由粉虱传播的影响产量的蔓状病毒。结果表明存在B的Q生物型。烟粉虱和重要入侵种以及预期的T.温室病毒检测试验确定了番茄褪绿病毒的潜在病毒个体。这些结果确定了一种能够携带植物病毒的新害虫，以及在一个没有报告的地区发现的病毒剂（ToCV），这可能会导致重大的产量损失。
Whiteflies are an insect group that comprises multiple species and biotypes, capable of affecting crops by phloem feeding, virus transmission and promotion of fungal colonization. The distribution of these pests is worldwide. In Costa Rica, a country located in the tropics, the most problematic whiteflies are Bemisia tabaci biotype B and Trialeurodes vaporariorum. In September 2009, two greenhouses in the Alfaro Ruiz region, northwest of the country's capital, San Jose, were surveyed as part of a larger effort to determine the occurrence of species and races of whiteflies in this agronomically important region. In addition, the insect samples were analyzed to determine the presence of Tomato chlorosis virus (ToCV), a yield-affecting crinivirus transmitted by whiteflies. The results revealed the presence of the Q biotype of B. tabaci, and important invasive species, as well as the expected T. vaporariorum. Viral detection assays identified potentially viruliferous individuals for Tomato chlorosis virus. These results identified a new pest capable of harbouring plant viruses has been identified, as well as a viral agent (ToCV) in a region where it was not reported, and which might cause significant yield losses.
