为更有效地利用昆虫引诱剂对桔小实蝇Bactrocera dorsalis(Hendel)进行害虫监测与防治,本文在弄清桔小实蝇雄虫对甲基丁香酚引诱剂趋向性的日动态基础上,研究评价了该引诱剂的不同使用方式对其作用持效期的影响。结果表明,桔小实蝇雄虫对甲基丁香酚的趋向高峰期出现在6∶00-9∶00时,12∶00-15∶00时;将引诱剂与活性炭混合,或采用5-10孔型诱芯瓶替代全开口型诱芯瓶,均减少了引诱剂的挥发浪费,可将其持效期延长近40 d,同时增加了引诱虫量。
In order to detect and control pests of Bactrocera dorsalis (Hendel) more effectively by using insect attractants, this paper studied the daily dynamics of the attractant tendency of methylcatechol attractants The effect of different ways of using the attractant on the duration of action was evaluated. The results showed that the peak of the trend of methyl eugenol in the male orange flycatchers appeared at 6: 00-9: 00, 12:00-15: 00; the attractant was mixed with activated carbon or 5-10 The hole-type vial instead of the full-opening lure-induced vial reduced the volatilization waste of the attractant and prolonged its persistence period by nearly 40 days, at the same time increased the amount of attractant.
