Abstract
銀葉粉蝨為菸草粉蝨種群(Bemisia tabaci complex)的B生理小種(B-type)，為台灣目前最具優勢的粉蝨族群。銀葉粉蝨在全球至少傳播 111 種以上之雙生病毒科 (Geminiviruses) 中 Begomovirus 屬的病毒，本屬病毒寄主非常廣泛，引起多種作物嚴重的經濟損失。台灣已記錄之雙生病毒有 7 種，其中以番茄黃化捲葉病毒及南瓜捲葉病毒發生最為普遍，在田間感染危害番茄、洋香瓜等蔬果。常用殺蟲劑對銀葉粉蝨卵與若蟲的毒效偏低，施用於田間無法達到防治效果。網室試驗結果顯示，番茄在苗 期至開花期間感染番茄黃化捲葉病毒(TYLCV)，嚴重影響結果數及果重，為有效遏止雙生病毒的蔓延，在蔬果開花前徹底防治粉蝨減少傳播為最佳管理策略。本文簡介銀葉粉蝨生態習性、傳毒機制、帶毒粉蝨檢測及監測方法，以及有效管理傳毒粉蝨之策略。
The silverleaf whitefly (Bemisia argentifolii Bellow & Perring), the B-type of Bemisia tabaci complex, is the most superior whitefly species in Taiwan. There are more than 111 Begomovirus (Family Geminiviridae) species transmitted by silverleaf whitefly globally. Among them seven begomoviruses reportedly existed in Taiwan, especially Tomato yellow leaf curl virus (TYLCV) and squash leaf curl virus (SLCV) that seriously cause yield loss on tomato and cantaloupe. It is inefficient to control silverleaf whitefly with insecticides in the flied since their toxicity to its eggs and larvae are low. Tomato plants-infected by Geminiviruses during the seeding stage were
unable to grow, bloom and set fruits normally. Therefore, an effective and suitable control tactic applied during the early planting period is imperative in order to reduce the population density of silverleaf whitefly and hence the reduction of Geminiviruses-infected tomato plants in net houses. This article describes the taxonomy, ecological habitats, virus transmission mechanism of silverleaf whitefly as well as the detection of silverleaf whitefly that carries the viruses and the effective
control strategies for silverleaf whitefly.
