摘要

瓜類作物包含木瓜、西瓜、洋香瓜、冬瓜、黃瓜、南瓜等；為我國重要蔬果之一，但由於海島型氣候－溫暖多濕之影響，所以病蟲害發生種類繁多，其中尤其以欠缺防治藥劑之病毒病害，常造成農友之重大損失。以往病毒病害之防治工作偏重於預防，例如健康種苗之選擇、栽種抗病品種、田間衛生管理、早期拔除病株、農機具之消毒、溫網室之隔離、適時防治媒介昆蟲等防治策略；但若已罹染病毒病害之植株，農民就束手無策了。最近生物技術突飛猛進，導入了對植物病毒病害新的防治技術及觀念，例如病毒鞘蛋白轉基因植物、輕症病毒交互保護系統、RNA干擾技術等已有相當好之研究成果，相信若能再配合傳統之防治策略，則能為減少病毒病害對農作物之肆虐，開創出一條康莊大道。

Warm and humid weather allows many pests being able to colonized in Taiwan. Among these pests, plant viruses which without chemical controlling strategies are always causing economical lose to farmers. Traditional controlling strategies of plant virus diseases include growing healthy seedling, utilizing screen house and green-house to prevent insect vector from early invasion. Recently, well-developed biological technologies already have some approaches to control plant virus diseases, for example, transgene plants, cross protection against severe strain viruses, and RNA interference. It would be a trend that merging traditional controlling strategies with new biological technology to prevent crops from plant virus infection.
