Abstract
利用盆栽臺南五號及田間種植之相同稻種，於其分蘗初期、分蘗末期、孕穗初期、孕穗末期、乳熟期及糊熟期分別網罩不同數目之3~4齡褐飛蝨危害七天，結果發現稻穀損失按其重輕次序為分蘗初期、孕穗初期、孕穗末期、乳熟期、及分蘗末期，而以糊熟期受害損失最輕。
Various population levels of 3rd-4th instarnymph of the planthopper (BPH) were caged on single-hill pots as well as 20-hill plot of Tainan 5 rice plants at 6 different growing stages for a week period. The results revealed that the severity of damage was in the order of initial tillering, initial booting, maximum booting, milky, maxium tillering, and doughy stage.
