摘要

在臺灣茄園為害之葉蟎有數種，屏東及南投地區主要為神澤氏葉蟎（Tetranychus kanzawai Kishida），臺中及彰化地區則除神澤氏葉蟎外，赤葉蟎（T. cinnabarinus Boisduval）及二點葉蟎（T. urticae（Koch））亦普遍發生；此外偶而亦可發現偽二點葉蟎（T. truncatus Ehara）及錫蘭偽葉蟎（Brevipalpus obovatus Donnadieu）。1990年及1991年調查園中赤葉蟎年發生兩次高峰，第一次在5-7月間，後因降雨而被抑制；第二次在8-10月間不降雨時。調查期間赤葉蟎之族群消長主要受降雨影響，而溫度及相對濕度之影響較不明顯。南黃薊馬（Thrips palmi Karny）主要發生於5月間，其族群消長亦主要受降雨影響。二點小綠葉蟬（Chlorita biguttula biguttula （Ishida））則全期均有發生。三種害蟲之發生情形均與臺灣南部有差異。

Several species of tetranychid invaded eggplant in Taiwan. Tetranychus kanzawai Kishida dominates in Pintung and Nantou, but T. cinnabarinus Boisduval and T. urticae (Koch) share with T. kanzawai in Taichung and Changhwa. Other tetranychoids found on eggplant include T. truncatus Ehara and Brevipalpus obovatus Donnadieu. Surveyed consecutively in Taiwan Agricultural Research Institute during 1990 and 1991, the population of T. cinnabarinus peaked twice in both years. The first peak appeared on May-July, after the rainy season which usually occurred arround May and June, then diminished by rainfall. The second peak was found on September-October, whenever the rainfall is not heavy. The influence of temperature and relative humidity on the spider mite population is not as obvious as rainfall. The population of Thrips palmi Karny peaked on May, and was surppressed mainly by rainfall too. Chlorita biguttula biguttula (Ishida) infested eggplant all growing seasons. Population fluctuation of these three pests in central Taiwan differs to which in southern Taiwan.
