Host Plant Preference Study for Ceratothripoides claratris (Shumsher) (Thysanoptera: Thripidae) and CaCV (Genus Tospovirus; Family Bunyaviridae) in Bangkok, Thailand
N. Steenken and N. Halaweh

Abstract:
Host plant preference of Ceratothripoides claratris and Capsicum chlorosis virus (CaCV) were conducted in Bangkok, Thailand. More information about the host plants of CaCV and its thrips vector is needed, which could help working out cultural control measures that might hinder spread of the virus and pest population growth. The potential relevance of the results for crop rotation approaches that would reduce tospovirus epidemics is discussed and common pea is suggested to be integrated in crop rotation. Fourteen crop plants were potted and placed in a greenhouse, which was covered with non-thrips proof net to allow natural infestation. Thereafter, the number of adult thrips and larvae was counted in order to determine host preference. The susceptibility of plants to CaCV was tested by ELISA. Ceratothripoides claratris was the predominant thrips species that infested all offered plant species except for angled luffa and common pea. As scarce other thrips species were recorded, the high numbers of larvae were assumed to be Ceratothripoides claratris larval stages. Ceratothripoides claratris had a clear and significant preference to hosts in the families Solanaceae and Cucurbitaceae. Tospovirus could be detected in tomato, pepper and tobacco, which all belong to the family of Solanaceae.
