The oriental fruit moth (OFM) is a worldwide fruit-boring insect pest. In China, OFM monitoring traps use a sex pheromone lure, but their overall design is varied. As such, there is a critical need to develop a standardised OFM trap design. In this field study, ten different trap shapes in varying combinations of colours and sizes (such as trap length and surface area) were examined.
The results showed that there was no significant difference in the trapping efficiency between eight colours. The ship-shaped trap could kill more OFM in a short period, whereas the automatic watering basin trap could be more effective in the long run. The optimal trapping diameter of the basin trap was 25 cm. The trapping efficiency of triangle traps with diameters of less than 10 cm was better than that of triangle traps with diameters of over 30 cm. The trapping number of pasteboard traps obviously declined when the surface area increased, and the pasteboard trap with a single board possessed excellent trapping efficiency.
The results provide useful information for the design of standardised sex pheromone traps for monitoring as well as trapping of OFM in the field.
东方果实蝇是一种世界性的果实蛀虫。在中国，东方果实蝇监测诱捕器使用性信息素诱饵，但它们的整体设计各不相同。因此，需要开发标准化的东方果实蝇诱捕器设计。在这项现场研究中，检查了十种不同形状的诱捕器，它们的颜色和大小（如诱捕器长度和表面积）组合不同。
结果表明，八种颜色的诱捕效率没有显著差异。船形诱捕器在短时间内可以杀死更多的东方果实蝇，而自动浇水盆形诱捕器则在长期内更有效。盆形诱捕器的最佳诱捕直径为 25 厘米。直径小于 10 厘米的三角形诱捕器的诱捕效率优于直径大于 30 厘米的三角形诱捕器。当表面积增加时，纸板诱捕器的诱捕数量明显下降，而单块纸板诱捕器具有极好的诱捕效率。
这些结果为设计标准化的性信息素诱捕器提供了有用的信息，用于监测和田间诱捕东方果实蝇。
