They usually are pale yellow in color but sometimes are nearly white. Immediate identification and implementation of controls are critical. The adult chilli thrips is approximately 1⁄2 the length of the western flower thrip. The thrips vectors and the viruses making up the Tospoviruses have large, overlapping host ranges that make management of virus spread one of the greatest challenges facing agricultural and ornamental industries today. The virus caused local and systemic infections on Cucumis sativus, Nicotiana benthamiana, and N. clevelandii and induced local necrotic lesions only on Chenopodium quinoa, C. amaranticolor, C. ficifolium, C. murale, Petunia hybrida, Cucurbita melo, Zinnia elegans, and Spinacia oleracea.

In addition, MAbs to WBNV NP strongly reacted with the NPs of WSMoV and HT-1, but did not react with those of PBNV and CCSV. The yields of the purified NPs of WBNV and PBNV from 100 g infected tissues were approximately 1.25 ~ 2.5 mg and 0.1~0.2 mg, respectively. than the leaf buds, leaf size over broader than leaf buds. In response, leaves, buds and fruits may turn bronze in color, Ludwig said. The infected squash leaves were harvested for purification of the expressed NPs by a method involving differential centrifugation and slab gel electrophoresis.
