DETECTION OF TOMATO CHLOROSIS VIRUS AND ITS VECTOR TRIALEURODES VAPORARIORUM IN GREENHOUSE-GROWN TOMATO AND SWEET PEPPER IN THE CARTAGO PROVINCE, COSTA RICA

摘要

Whiteflies and whitefly-borne viruses are major constraints to the production of tomato and sweet pepper both in field and greenhouses settings. Limited data exist about the epidemiological factors related to these pests and pathogens for greenhouse production in Costa Rica. The aim of this study was to determine the incidence of Tomato chlorosis virus (ToCV) and its vector Trialeurodes vaporariorum in tomato and sweet pepper grown in greenhouses in the Cartago province. Results showed that both vector and virus are widespread across all the greenhouses in the province. Detection of ToCV in several weeds shows its adaptation to this type of environment. Possible evidence for genetic differentiation between T. vaporariorum populations is presented.
