中文摘要 | 番茄斑潛蠅(Liriomyza bryoniae (Kaltenbach))對豌豆之危害始見於播種 後20∼30天。其族群密度隨植株成長而逐漸升高,危害益趨嚴重。在發生盛期 豌豆之被害株率可達100%,被害葉率達34%。在畦面覆蓋黑色塑膠布、稻草及 不覆蓋之豌豆田,使用黃色粘板誘捕番茄斑潛蠅成蟲分別為50.5、195.4及218.1 隻/片/週,前者與後者有顯著差異,但在植株上幼蟲族群密度三者間差異不顯著。 比較不同顏色粘板及水盤於距地面0、50、100及150cm等4種不同高度誘捕成 蟲之效果,均以距地面0cm之黃色粘板及水盤之誘捕蟲數為最多,與其他三種 不同高度之誘捕蟲數有顯著差異。在比較不同顏色水盤使用不同溶液對成蟲之誘 捕效果,顯示以黃色水盤裝水1,600ml加洗潔精4ml之誘捕效果最佳,與其他處 理比較呈顯著差異,對於雌蟲的誘捕蟲數約為雄蟲的3∼4倍。藥劑防治以75% 賽滅淨(Cyromazine) W.P. 6,000倍之防治率平均達90%最佳,單獨使用黃色粘板 、水盤或塑膠布對斑潛蠅之防治率均在60%以下,但與藥劑配合使用,則可進一 步減少番茄斑潛蠅之危害。 |
英文摘要 | Pea plants were usually attacked by tomato leafminer (Liriomyza bryoniae (Kaltenbach)) since 20 to 30 days after sowing. The population density of the pest and their damage on plants increased gradually with the plant development. The rate of infested plant and damaged leaf could reach 100% and 34%, respectively at population peak of the insects on the varieties of Taichung 11, 12 and 13. The average number of L. bryoniae adults attracted by a yellow sticky card in the pea field mulched with black plastic film, rice straw and non-mulching plots were 50.5, 195.4 and 281.1 per week, however, there were no significant difference of larvae population density in pea plants among three mulching treatments. The yellow sticky cards and yellow water pans placed on the ground level attracted a significant higher number of adults than those placed higher than the crop. When water pan trap was used, adding 4 cc detergent in 1,600 cc water in a trap could catch more adults than other treatment. The female adults attracted by the yellow water-pan trap was 3 to 4 times higher than male adults. Among the chemicals tested, 75% Cyromazine W.P. 6,000X showed the best control of the pest, rate of control reached as high as 90%. Using yellow sticky cards, yellow water pan trap or plastic film alone for control of L. bryoniae was far beyond satisfactory, but when they were used integrated with chemicals in a wide area could reduce the damage of the leafminers . |
