以中央研究院提供之歐洲玉米螟性費洛蒙,每盒使用1 mg,於12月至7月間皆未誘到雄蛾,所以台南地區之玉米螟應屬於亞洲玉米螟。不同日齡處女蛾之引誘雄蛾能力,以第2日齡最强,而後3日齡、4日齡、5日齡依次遞減,超過5日齡之處女蛾,其引誘力甚弱。亞洲玉米螟雄蛾在田間尋找配偶之活動時間,於12月間以晚上10時至淩晨2時為主。在落花生田誘殺之雄蛾數目遠較玉米田或空田多,可知雄蛾具有喜好在矮欉植物中活動之習性,此可供防治之參考。亞洲玉米螟性費洛蒙,在不同成份比例中,順-12-乙酸十四烯醋:反12-乙酸十四烯醋:乙酸十四(烷)醋:乙酸十六(烷)醋=38:37:33:2及75:25:0:0之誘蟲效果較佳,不遜於2隻處女蛾。上列四種成份38:27:33:2之配方,國內製品之誘殺效果,仍較國外製品差。每盒劑量以1 mg較理想。有效期間30天以上。濕式、粘著式及保特瓶式等不同型態誘蟲器之誘虫效果,以濕式最佳,粘著式次之,保特瓶式最差。不同構造保特瓶誘蟲器之誘蟲效果以上位開口較底位全開口為佳,但較粘著式差。不同性費洛蒙施效基,在春季塑膠管與橡皮帽之誘蟲效果差異小。塑膠管施放基封口有否剪開之誘蟲效果,在冬天處理間差異不大,但在夏天以雙開口式較佳。誘蟲器設放高度應依作物高度調整,在1m以下時,高於生長點為宜,其後可調整至方便操作之高度,獨立飼料用玉米田周圍之高度不宜超過1m。亞洲玉米螟雄蛾在台南本場周年發生量,以11月至2月間較多,3月至5月間次之,6月至9月間較少。
Synthetic sex pheromone of European corn borer obtained from Academia Sinica failed to attract male moths in the test conducted between December 1989 and July 1990 in Tainan.
The 2-days-old of virgin females showed the best results of attraction to the moths followed by the 3-days-old ones. For those females of 5-days-old or more were very little in their efficacy of attraction. The results of the experiment conducted in December indicated that the male moths were much more active around midnight and the main time of mating was found between 10 PM and 2 AM. More make moths were trapped in peanut field than corn field or fallow field. It means that the male moths preferred to lodge in the canopy of short plants.
Combinations of Z-12-tetradecenyl acetate, E-12-tetradecenyl acetate, tetradecyl acetate, and hexadecyl acetate at the ratio of 38:27:33:2 and 75:25:0:0 showed the best results of trapping, and their results were as good as 2 virgin females. Better trapping was observed in the sex pheromone imported from the U.S. (foreign country) than the local products of Z-12-tetradecenyl acetate: E-12-tetradecenyl acetate:tetradecyl acetate : hexadecyl acetate at the ratio of 38:27:33:2. The best dose for trapping of Asian corn borer was found with 1 mg/trap of synthetic sex pheromone and the effectiveness could last for 30 days or more.
The results of trapping with different type of traps showed that wet type of traps was the best followed by sticky paper type and PET bottle traps. Among the various type of PET bottle traps, those opened at the rip end were better than those opened at the bottom end. However they were still worse than the sticky paper traps.
In spring, the efficiency of trapping varied in the different type of dispensers. However, no difference was observed between rubber septum and PE tube dispensers in the spring. In winter, the PE tube dispenser was closed or not did not influence the efficacy of trapping. In summer, both ends kept opened was the best.
The setting height of the traps depends on the canopy height of the plants, when the canopy height is less than 1 meter, the traps should be set higher than the growth points, when the canopy height is higher than 1 meter such as corn, the trap can be set around 1 meter high. Higher than 1 meter is difficult to manipulate in the filed.
The height population dynamics of Asian corn borer in Tainan was found between November and February in a year, followed by the population between March and May, while the population between June and September was the lowest.
