中文摘要 | 由2000至2004年利用黃色粘紙於鳳山地區檬果園內偵測綠葉蟬(Idioscopus clypealis)之族群消長,結果顯示其族群均於開花期(1~4月)最高,且為褐葉蟬之3.5倍。開花期每週36張粘紙所捕捉到蟲數為466.3~2243.5隻,平均1312.4隻;其次結果期(5~7月)216.4~824.8隻,平均600.8隻,其他時期則較少。在開花期氣象單因子中以溫度與綠葉蟬數之直線關係(R^2=0.7211, p=0.0012)較明顯,結果期關係次之(R^2=0.6302, p=0.0025);開花期氣象雙因子中,溫度及雨量與綠葉蟬數相關性高(R^2=0.8102, p=0.002),與溫度、相對濕度相關性也高(R^2=0.8314, p=0.0018),如同時以溫度、雨量及相對濕度三因子進行複迴歸分析時,其間相關性更高(R^2=0.8517, p=0.0026)。預測檬果綠葉蟬之實測與估算值比較,均以開花期同時與溫度、雨量、相對濕度之複迴歸導出來蟲數誤差最小,5.68~9.93%,平均7.69%,另利用路徑分析變數因子之貢獻率,為溫度31.42%,相對濕度10.43%及雨量8.72%,故氣候因子中以溫度佔較大影響力。 |
英文摘要 | Mango green leafhopper, Idioscopus clypealis Leth, is a most destructive insect pest during mango flowering stage. The insect feed on the tender shoots and excreted a sticky substance which cause sooty molds grow. This experiment was conducted to investigate the population fluctuation of mango green leafhopper to determine factors that affecting the population abundance, based on data collecting from 2000 to 2004 in a mango orchard at Fengshan in southern Taiwan. The population abundance of the mango green leafhopper in mango blossom stage was highly correlated with the climatic factors such as temperature (p=0.0012), rainfall (p=0.0902) and relative humidity (p=0.0665), and among them, temperature affected more than others. |
