    Abstract:
    During a cucurbit disease survey in August 2004, severe symptoms resembling those caused by viruses were observed on bottlegourd (Lagenaria siceraria (Molina) Standl.) in the Vojvodina region of Serbia. Symptoms included stunting, mosaic, green veinbanding, blistering, yellowing, chlorotic spots, leaf deformation, and fruit distortion. Leaf samples from 25 symptomatic plants were collected from two localities for virus identification using mechanical transmission and serological testing. Crude sap extract from leaf samples was mechanically inoculated onto bottlegourd and pumpkin (Cucurbita pepo) under greenhouse conditions. Field-collected bottlegourd and inoculated plants were tested using double-antibody sandwich enzyme-linked immunosorbent assays (DAS-ELISA). Positive reactions were obtained on collected and inoculated plants with polyclonal antiserum (Loewe Biochemica, Sauerlach, Germany) to Zucchini yellow mosaic virus(ZYMV) in 23 samples, with antiserum to Watermelon mosaic virus (WMV) in eight samples, and with antiserum to Cucumber mosaic virus (CMV) in seven samples. Each of the three viruses was detected in single as well as in mixed infections with the other two viruses. Biological characterization of viruses detected in single infections was done on the following indicator plants: Chenopodium amaranticolor, C. quinoa, Cucumis sativus, Cucumis melo, Citrullus lanatus, Nicotiana glutinosa, and N. tabacum cv. Samsun. The symptoms observed on indicator plants for each isolate corresponded to the results of DAS-ELISA (2,3). All three viruses are known to be important pathogens of cucurbit plants and were previously reported in pumpkin in Serbia (1). To our knowledge, this is the first report of ZYMV, WMV, and CMV in bottlegourd in Serbia. References: (1) N. Dukić et al. J. Agric. Sci. 47:149, 2002. (2) D. E. Lesemann et al. Phytopathol.
