摘要 为明确对柑橘大实蝇具有引诱或拒避作用的植物精油或挥发物,通过Y形嗅觉仪分别测定柑橘大实蝇雌、雄成虫对橘子精油、橙叶精油、橙花精油、柠檬桉精油、薄荷素精油、栀子花精油、D-柠檬烯、芳樟醇和月桂烯的选择率。结果表明,柑橘大实蝇雄虫倾向于选择橘子精油、橙花精油、D-柠檬烯、柠檬桉精油、栀子花精油,雌虫倾向于选择芳樟醇和柠檬桉精油。柠檬桉精油对柑橘大实蝇雌虫和雄虫均有显著的引诱作用,雌虫对柠檬桉精油的选择率为52.38%,雄虫的选择率也达到了50%。本研究为开发对柑橘大实蝇雌、雄成虫均具有引诱作用的引诱剂提供了一定的理论参考。

Abstract

In order to identify the plant essential oils or volatiles with attractive or repellent activities, the selection rate of Bactrocera minax for citrus oil, petitgrain oil, neroli, citriodora oil, peppermint oil, gardenia oil, D-limonene, linalool and myrcene were tested by using Y-tube olfactometer. The results showed that the male of B.minax preferred to select the citrus oil, neroli, D-limonene, citriodora oil and gardenia oil, while the female of B.minax preferred to select linalool and citriodora oil. The female and male of B.minax could be attracted by citriodora oil, with a selection rate of 52.38% and 50.0%, respectively. Therefore, the citriodora oil may be developed as the attractant from plants for trapping the male and female of B.minax.

柑橘大實蝇Bactrocera minax (Enderlein),属双翅目,芒角亚目,实蝇科,果实蝇属,大实蝇亚属,是主要分布于我国的柑橘类重要害虫,常对柑橘造成毁灭性的危害[1]。柑橘大实蝇1年发生1代,主要以成虫产卵于幼果,卵孵化成幼虫蛀食柑橘果实为害[2],幼虫出果后在土壤中化蛹,卵、幼虫、蛹期阶段均较隐蔽而不利于防治,成虫诱杀因高效、操作方便和绿色环保而成为防控柑橘大实蝇的关键技术之一[3]。

植食性昆虫能够利用寄主植物的挥发物搜寻食物、配偶或适宜的产卵场所[4],而非寄主植物的挥发性物质对植食性昆虫的行为也有一定程度的影响,如菊花Chrysanthemum×morifolium提取物可抑制小菜蛾Plutella xylostella 对寄主的趋性[5]。……
