摘要

茄園南黃薊馬（Thrips palmi Karny）對不同背景色之偏好性試驗，以藍色黏板（或黃色黏板）為主誘集色搭配紫、粉紅、黑、黃（藍）、白及紅色為背景色進行顏色偏好性試驗，結果顯示藍色黏板（或黃色黏板）為主誘殺板，背景色為黃色（或藍色）可誘殺南黃薊馬11.50隻，較其它處理組有顯著差異。篩選數種氣味化合物對茄園南黃薊馬之誘殺效果，實驗結果發現p-anisaldehyde 及ethyl nicotinate較對照組分別高2.56及2.38倍之誘殺效果，進一步將p-anisaldehyde及ethyl nicotinate稀釋為1、5、12.5、25、50及100%之不同濃度對南黃薊馬之誘引倍數分別為1.00－1.85倍及1.25－1.75倍不等，統計分析差異不顯著，顯示氣味化合物經稀釋後對南黃薊馬之誘引效果，並未隨濃度降低而漸降。另外發現茄株上面鋪蓋黃色塑膠布及噴施香茅油及薄荷油可分別降低5.10及3.47倍之南黃薊馬蟲數，顯示此項防治措施對南黃薊馬具忌避趨離之作用，可做為非農藥防治之參考方法。

Capture of the southern yellow thrips, Thrips palmi Karny on blue or yellow traps when placed in front of violet, pink, black, yellow (or blue), white and red as background color was studied in an eggplant field. The results showed that the blue (or yellow) traps placed in front of a yellow (or blue) background could capture 11.5 thrips, it captured significantly more thrips than traps with other background colors. The attract effects were tested for some volatile chemicals against the southern yellow thrips. Our results showed the attract ratios were 2.56 for p-anisaldehyde and 2.38 folds for ethyl nicotinate than the blank. Further more the volatile chemicals were diluted to a series of various concentrations, such as 1, 5, 12.5, 25, 50 and 100%. The attract effects of different concentrations of p-anisaldehyde and ethyl nicotinate for thrips were 1 to1.85 and 1.25 to 1.75 folds, separately. It appearance the diluted volatile chemicals didn't decrease the attract effects for the thrips. When sprayed the citronella oil or peppermint oil and combined to yellow plastic covered could decrease 5.10 and 3.47 folds of thrips, separately. It was apparent these control method had repellent effect and could avoid damage from the thrips on the eggplant. The above integrated control methods maybe can apply in non-chemicals to control the thrips in eggplant by the farmers.
