【摘要】 为了澄清中国玉米螟的种名,1979年8月,我们用一种亚洲玉米螟Ostrinia furnacalis(Guen(?)e)和三种欧洲玉米螟O.nubilalis(H(?)bner)不同配比的性诱剂,在河南许昌作了田间诱捕试验。试验结果表明:亚洲玉米螟性诱剂顺12-和反12-十四烯醇乙酸醑及醋酸十四(烷)醇34∶39∶27,11天132盆次共诱到71头蛾,效果良好:欧洲玉米螟性诱剂顺11-和反11-十四烯醇乙酸酯97∶3和3∶97,前者共诱到3头蛾,后者共诱到2头蛾,有一定活性:而欧洲玉米螟性诱剂顺11-和反11-十四烯醇乙酸酯35∶65没有诱到蛾,无话性。因此,初步证明:(1)河南许昌的玉米螟主要为亚洲玉米螟,至于是否有欧洲玉米螟存在,须进一步作试验和对标本进行鉴定后才能确定:(2)性诱剂装在橡皮塞内的效果优于装在毛细管内的效果;(3)用诱蛾水盆比用“非洛康”捕蛾器纸盆效果好。

【Abstract】 In August 1979, field test with one kind of Asian corn borer sex pheromone and three kinds of European corn borer pheromone, with different ratio of its mixing components, was conducted in corn field near by Xiuchang. The results showed that the Asian borer sex pheromone (Z)-12-tetradecen-l-ol acetate, (E)-12-tetradecen-l-ol acetate and tetradecyl acetate 34:39:27 tested for 11 days, using 132 pan-times, 71 moths were captured, the effect was significant. When European borer sex pheromone (Z)-and (E)-ll-tetradecen-l-ol acetate 97:3 and 3:97 were used, only 3 moths were captured for the former and 2 moths were attracted by the later, indicating these pheromones have certain active capacity. But, European borer sex pheromone (Z)-and (E)-ll-tetradecen-l-ol acetate 35:65 captured none of the moths, indicating it has no any active capacity. Therefore it maybe concluded that: (1) the corn borers in Xiuchang region of Henan Province are mainly Asian corn borers, whether there are European corn borers or not, further study and identification of large number of specimens are needed; (2) rubber septa impregnated with sex pheromone has better effect than those impregnated in capillaries, and (3) the effect of using water-basin traps is better than using "Pherocon" traps.
