【摘要】 采用三角型及Ｕｎｉ－ｔｒａｐ型诱捕器．对兴安落叶松鞘蛾（ＣｏｌｅｏｐｈｏｒａｄａｈｕｒｉｃａＦｌｋｖ．）人工合成性引诱剂（Ｚ５－１０：ＯＨ）的最佳诱虫剂量、昼夜反应节律．诱捕器设置高度以及在发生期监测上应用等内容进行了研究、结果表明：供试的５种剂量（１～１０００μｇ）均显示出一定的诱虫活性，在中低剂量（１００μｇ）范围内．诱虫数量随诱芯剂量的增大而增加：超过１００μｇ时、其诱虫数量反而随着剂量的增大逐渐下降、故１００μｇＺ５－１０：ＯＨ为此虫的最佳诱虫剂量。雄蛾对该性引诱剂的昼夜越性反应主要出现在２２时～１０时．高峰期为２时～８时。利用１００μｇＺ５－１０：ＯＨ对雄蛾季节性飞行规律的监测发现、其成虫期出现两个扬飞高峰就相同剂量诱芯而言。非粘胶Ｕｎｉ－ｔｒａｐ型诱捕器的诱虫效果明显好于三角型粘胶诱捕器。更多还原

【Abstract】 The sex-attractant of Coleophora dahurica Flkv. Z5-10: OH. was field tested by using sticky Delta-traps and non-sticky Uni-traps with special emphasis on optimal dose. diurnal response of males. trap height effect and monitoring adult phenology etc. All five test doses of Z5- 10:OH, from 1μg to 1000μg.were effective in capturing male moths compared to the blank. Captures increased with raising the Z5- 10:OH dose up to 100μg and decreased gradually with the further increase of dose (eg. 500μg and 1 000μg ). Thus. the 100μg Z5- 10: OH could be defined as a C. dahurica" optimal or standard lure ".Diurnal response of males to the attractant mainly occurred from 22 to 10 o’clock. with a response peak recorded at 2 ～ 8 o’ clock. Adult pherologymonitored by sex-attractant traps showed a 25 days of night Period (form May 26 to June 19 ) with peaks occurring from May 31 to June 3. and from June 9 to 13. In comparison with Delta-trap. the Uni-trap revealed a significantly higher capturing efficacy when baited with the same dose of Z5- 10:OH.更多还原
