摘要：為了有效控制小菜蛾的發(fā)生和危害。以甘藍為試材，研究了不同顏色誘捕器和誘蟲板組合對露地甘藍小菜蛾成蟲的誘捕效果。結果表明，4種組合處理對露地甘藍小菜蛾成蟲均有較好的誘捕效果，誘捕效果由高到低依次為白色誘捕器＋白色誘蟲板組合、白色誘捕器＋黃色誘蟲板組合、綠色誘捕器＋白色誘蟲板組合、綠色誘捕器＋黃色誘蟲板組合。白色邊框誘捕器＋白色誘蟲板組合可作為露地甘藍小菜蛾成蟲綠色防控措施在生產(chǎn)上應用。

Abstract： To provide references for the monitoring and green prevention and control of cabbage moth （Plutella xylostella）， the trapping efficiency under combination of different color catchers and insect-attracting boards on moth of Plutella xylostella in open cabbage field was studied. The results showed that all four combinations had good trapping effects on moth of Plutella xylostella in open cabbage field， and the ranking of trapping efficiency was as followed the combination of white catcher plus white insect-attracting board > the combination of white catcher plus yellow insect-attracting board > the combination of green catcher plus white insect-attracting board > the combination of green catcher plus yellow insect-attracting board. Therefore， the combination of white catcher and white insect-attracting board could be used as the green prevention and control measure on the control of moth of Plutella xylostella in open field cabbage production.

Key words： Catcher; Insect-attracting board; Cabbage; Plutella xylostella; Trapping efficiency

小菜蛾是為害甘藍、紫甘藍的主要害蟲，在天祝呈逐年加重趨勢，發(fā)生危害頻率高，不易防治，影響甘藍的正常生長，常造成甘藍減產(chǎn)、甚至絕收。小菜蛾對常用有機磷和菊酯類農(nóng)藥已產(chǎn)生較高的抗藥性［1 - 3 ］，藥劑選擇范圍比較窄，是當前生產(chǎn)上化學殺蟲劑防治困難的典型害蟲之一。天祝縣境內(nèi)海拔2 040～4 874 m，年平均氣溫0.3 ℃，年降水量407.4 mm，夏季晝夜溫差大，適宜小菜蛾的發(fā)生危害。在實際生產(chǎn)中，種植戶常通過提高施藥濃度、增加使用次數(shù)等方法來防治，致使天敵昆蟲被大量殺傷，造成害蟲再度猖獗，導致高原夏菜中農(nóng)藥殘留超標，影響了高原夏菜品質(zhì)。為了有效控制小菜蛾的發(fā)生和危害，生產(chǎn)綠色食品甘藍，我們對不同顏色誘捕器和誘蟲板組合防治露地甘藍小菜蛾成蟲的效果進行了試驗，現(xiàn)將試驗結果報道如下。
