Abstract
自 1982 至 1988 年於嘉義溪口地區設置早、中及晚植稻調查田觀察褐飛蝨在本地區之族群變動，結果顯示褐飛蝨在一期稻侵入稻田數甚少，侵入期大部無法追蹤；在全期作中可完成三個世代，第一世代成蟲一般於4月下旬至5月上旬出現，其後約一個月完成一個世代；族群最高峰大部出現於水稻收獲前 1-2 週，每叢稻最高蟲數為 10.2 隻，平均為 1.33 隻。
The population changes of brown planthopper, Nilaparvata lugens (Homoptera: Delphacidae) in paddy fields were investigated for the first and second rice crops in Chianan area from 1982 to 1988. The results revealed that the immigration of brown planthopper in the initial stage of the first rice crop in most cases could not be traced due to low immigrant.
