番椒（Capsicum annuum L., C. frutescens L.）主要分為甜椒和辣椒，為重要的茄科(Solanaceae)作物，台灣危害番椒病毒有11 種之多，自96 年起調查病毒在田間發生情形，甜椒樣本採集自露天栽培甜椒者，病毒發生率不高，各病毒檢出率差異不大，介於6.0-10.5%之間。設施栽培者，potyvirus 的檢出率遠高於其他病毒，且出現病毒病徵植株常呈現區塊存在，疑似人為傳播所致。檢測的辣椒樣本中，除了potyviruses，CMV 感染率最高，複合感染的比例高達80.5%。地球暖化雨量分布不均，很容易造成小型昆蟲大量發生，尤其是媒介病毒傳播的薊馬和粉蝨。98 年在仁愛鄉採集205 個番椒樣本，測到薊馬傳播的TSWV 感染比例達86.8%，99 年則降至32.0%。調查中粉蝨傳播的TYLCV 在番椒的感染率不高，鑒於其對番茄造成的嚴重危害，未來對番椒生產的影響亦須密切注意。
Pepper (Capsicum annuum L., C. frutescens L.) is divided into sweet pepper and chili pepper, as an important vegetable crops. There are 11 species of viruses infecting pepper in Taiwan. Pepper samples showed symptoms could be caused by virus were collected for analysis with ELISA and polymerase chain reaction (PCR). The virus infection rate of sweet pepper collected from open field is insignificant, ranging from 6.0-10.5% respectively. The infection rate of potyviruses in sweet pepper is much higher than other viruses if samples collected from net house. In chili pepper, the infection rate of CMV is the highest and 80.5% of samples showed co-infection with potyviruses. Since abnormal rainfall distribution of global warming, the population of virus vector may be increased and caused serious diseases. A severe disease on pepper plants showing chlorosis, necrosis and die back were observed in Renai Township in 2009. The causal agent is TSWV, a thrip transmitted tospovirus. The infection rate is higher than 30% but dropped to lower than 5% till 2010. In this survey, TYLCV, the whitefly transmitted virus does not show high infection rate in pepper. Since TYLCV caused dramatic losses in tomato, its influence in pepper production should pay more attention.
