Summary
Surveys for virus and virus-like plant diseases were conducted in the US territory of Guam; in the Commonwealth of the Northern Mariana Islands (CNMI), on the islands of Saipan, Rota and Tinian; in the Republic of the Marshall Islands (RMI) on the atolls of Majuro and Arno; and on Nauru. New virus records for Guam were those of Watermelon mosaic virus (WMV) in bitter gourd (Momordica charantia), Citrus tristeza virus (CTV) in several Citrus spp., Potato virus Y (PVY) in tomato (Lycopersicon esculentum) and chilli (Capsicum annuum var. annuum), Tomato mosaic virus (ToMV) in tomato, and Cymbidium mosaic virus (CymMV) in ornamental orchids (Dendrobium spp. and Oncidium sp.), all detected by enzyme-linked immunosorbent assay (ELISA); and of Taro bacilliform virus (TaBV) in taro (Colocasia esculenta), detected by polymerase chain reaction (PCR). The survey of CNMI provided the first laboratory confirmation, by ELISA, of the presence of Banana bunchy top virus (BBTV) in banana (Musa sp.) following many visual reports of bunchy-top-diseaselike symptoms. Other new virus records for CNMI, determined by ELISA, were of Dasheen mosaic virus (DsMV) in taro (C. esculenta and Xanthosoma sp.), CTV in three Citrus sp., and both Tobacco mosaic virus (TMV) and ToMV in chilli. New virus records for RMI were of the cucurbit-infecting strain of Papaya ringspot virus (PRSV-W) in pumpkin (Cucurbita maxima) and cucumber (Cucumis\n sativus) and Bean common mosaic virus (BCMV) in Phaseolus vulgaris (garden bean), both detected by ELISA. New records for Nauru were of Zucchini yellow mosaic virus (ZYMV) in pumpkin, bitter gourd, and ridge gourd (Luffa acutangula), PRSV-W in bitter gourd, BCMV in snakebean V. unguiculata ssp. unguiculata), Cucumber mosaic virus (CMV) in the roadside weeds Synedrella nodiflora and Physalis angulata, and DsMV in taro (C. esculenta), all detected by ELISA; plus TaBV in taro (C. esculenta) detected by PCR.
