Abstract : Mango green leafhopper, Idioscopus clypealis, is the most destructive insect pest during the mango flowering stage. The insect feed on the tender shoots and excreted a sticky substance which causes sooty moulds 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 collected from 2000 to 2004 in a mango orchard at Fengshan in southern Taiwan. The population abundance of the mango green leafhopper during the 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 had more effect compared with the other factors.
