中文摘要 | 於東部鹿野、太麻里、瑞穗等茶區監測主要茶樹病蟲害的族群變動。四年來調查結果顯示茶園病蟲害發生頻率以茶枝枯病(Macrophoma theicola Petch)為首,每次調查都可發現,其餘依序為茶小綠葉蟬(Jacobiasca formosana Paoli)有88.2%,柑橘刺粉蝨(Aleurocanthus spiniferus (Quaintance))為81.1%,茶捲葉蛾(Homona magnanima Diaknoff)為80.7%,茶姬捲葉蛾(Adoxophyes sp)為75.5%,茶葉蟎(Oligonychus coffeae Nietner)為42.1%,茶角盲椿象(Helopeltis fasciaticollis Poppius)為34.1%,茶黃薊馬(Scirtothrips dorsalis Hood)為16.1%,神澤氏葉蟎(Trtranychus kanzawai Kishida)為5.1%以及茶赤葉枯病(Glomerella cingulata (Stonem) Spauld & Schrank)為4.8%。四年中病蟲害的發生以2002年發生較前三年嚴重。茶小綠葉蟬一般在5月份時密度升高,以太麻里茶區發生較為嚴重;柑橘刺粉蝨在鹿野茶區發生較為嚴重,成蟲出現在4月、6月、8月及10月;茶姬捲葉蛾及茶捲葉蛾在前三年發生輕微,2002年以鹿野茶區發生較為嚴重,茶姬捲葉蛾在4月至6月及10月至11月、茶捲葉蛾在10月至次年3月發生密度較高;茶角盲椿象以太麻里茶區發生較為普遍,在5月至6月及8月至9月發生密度較高;茶葉蟎以瑞穗茶區發生較為嚴重,一般在4月至5月及7月至9月密度較高;茶枝枯病在鹿野茶區普遍發生,2002年發生最為嚴重,罹病率最高曾達83%。 |
英文摘要 | The population fluctuation of important tea pests and diseases was monitored at Luye, Taimali and Ruisui, in the eastern part of Taiwan from 1999 till 2002. Results showed that the die-back disease (Macrophoma theicola Petch) was found every month. The occurrence frequency for other pests and disease including tea leaf hopper (Jacobiasca formosana Paoli), citrus spiny-blackfly (Aleurocanthus spiniferus (Quaintance)), tea tortrix (Homona magnanima Diaknoff), smaller tea tortrix (Adoxophyes sp), red spider mite (Oligonychus coffeae Nietner), tea mosquito bug (Helopeltis fasciaticollis Poppius), yellow thrip (Scirtothrips dorsalis Hood), Kanzawa spider mite (Trtranychus kanzawai Kishida) and brown blight of tea (Glomerella cingulata (Stonem) Spauld & Schrank) was 88.2%, 81.1%, 80.7%, 75.5%, 42.1%, 34.1%, 16.1%, 5.1%, and 4.8%, respectively. Tea pests and diseases occurred more seriously in 2002 than the other three years. Generally, the population density of leafhopper was high from May. It was occurred more seriously in Taimali than the other two districts. Citrus spiny-blackflies occurred more seriously in Luye than the other two districts and the adults appeared in April, June, August and October. Smaller tea tortrix and tea mosquito bugs occurred during two periods, May to June and August to September, in Taimali. Red spider mites occurred more seriously in Ruisui and appeared seriously during April to May and July to September. Die-back disease was very prevalent in Luye with significant damage (83%) in late April in 2002. |
