Abstract
經四年來試驗結果顯示：花薊馬對柑桔幼果之傷害不明顯，但由接蟲試驗顯示開花初期接2對薊馬則對柑桔之著果便會有顯著影響，然而需要有多少數量之薊馬才會造成經濟為害損失，則尚有待進一步探討。由 3 天施一次及 6 天施藥一次之結果得知，以 2.8% 大禧 2000 倍之效果為最佳，50% 滅賜克 1000 倍為其次，藥效一般皆可維持 6 天。而由於 3 天施藥一次與 6 天施藥一次者之著果率與對照組比較差異都不明顯，故建議農民在柑桔開花期間儘可少用農藥來防治此種花薊馬。
In order to formulate effective control measures for the flower thrip, which becomes abundant when the citrus blooms, a study was taken to determine the damage of this insect pest to the lowering and fruit setting of citrus plant. Result of the experiments carried out at farmers' orchards and Chiayi Agricultural Experiment Station during 1983 to 1986 are summarized in the following. 1. Thrip damage to the young fruit was insignificant. 2. Fruiting was affected by two pairs of thrips introduced at blooming stage. Nevertheless, the economic injury level was not determined.
