摘要

於台灣為害檬果之葉蟬有二種，即為檬果褐葉蟬(Idioscopus niveosparsus Leth)與檬果綠葉蟬(I. clypealis Leth)。兩種葉蟬於愛文、金煌、海頓及本地種不同檬果品種植株上之分布比例（褐葉蟬：綠葉蟬）分別為1.04:1、1.43:1、0.99:1及0.32:1，顯然綠葉蟬於本地種檬果植株上較佔優勢。按愛文檬果株高區分，低於2公尺（小）、介於2~3公尺（中）及高於3公尺（大）等三種株高，調查二葉蟬之分布，其比例分別為1.93:1、104:1及0.31:1，而在本地種小、中、大棵果樹二種葉蟬之比例分別為。0.61:1、0.32:1及0.18:1，顯然植株較高大之檬果樹綠葉蟬族群量較大；另於混植有龍眼樹之愛文、海頓及本地種檬果植株上，兩種葉蟬之分布比例分別為0.69:1、0.75:1、0.27:1，顯然檬果園有龍眼樹混植時綠葉蟬較佔優勢。室內毒殺測試及田問防治試驗結果，2.8%賽洛寧乳劑對綠葉蟬防治效果最好，而5%護賽寧水溶劑及3%亞滅培乳劑則對檬果褐葉蟬防治效果較佳。

The field distribution and control of the two species of mango leafhopper, mango brown leafhopper (Idioscopus niveosparsus Leth) (MBL) and green leafhopper (I. clypealis Leth)(GL) were studied. The ratios of field populations of MBL and GL on the varieties of Irwin、Jin-huang、Haden and Native mango were 1.04:1、1.43:1、0.99:1 and 0.32:1, respectively. The population ratios of the two species (MBL:GL) on Irwin and Native mango plants lower than 2m、2 to 3m and taller than 3m in height were 1.93:1、1.04:1、0.31:1 and 0.61:1、0.32:1、0.18:1, respectively. These results indicated that GL prefers native mango and taller plants. However, the population of GL was more abundant than MBL when mango was mixed plantings with longan (Diamocarpus longana). Six insecticides were evaluated for their effectiveness against the leafhoppers in the laboratory and field conditions. Results indicated that 5% flucythrinate L. and 3% alphamethrin EC were more effective against the mango brown leafhopper and 2.8% cyhalothrin EC provided a better control of the green leafhopper.
