The objective of this thesis is to study viruses infecting plants in the family curcubitaceae in Coast and Dar es Salaam regions in Tanzania. The focus is on watermelon, cucumber and pumpkin farms and to study the incidence and distribution of three different viruses called Cucumber mosaic virus (CMV), Zucchini yellow mosaic virus (ZYMV) and Watermelon mosaic virus (WMV).
Samples were collected from farms on Coast and Dar es Salaam Regions, Tanzania. On the farms the farmers were asked questions about their experience about the viruses and diseases on the farms. The samples were tested to laboratory using ELISA-method and the results were read visually and by using ELISA plate reader.
26% of the collected samples were infected either with CMV, ZYMV or WMV. Some of the plants were infected with two of the viruses, one plant was infected by all three viruses. Only on 10% of the farms there were no symptomatic plants found and samples were tested negative, from 90% of the farms symptomatic plants were found and part of the samples were tested positive. The highest percentage of infected plants on one farm was 80%.
