Zeugodacus tau (Walker) (Diptera: Tephritidae) is an important agricultural pest currently managed primarily through the application of insecticides due to limited control strategies. Bait station devices are target specific and have emerged as a behaviorally based alternative to traditional insecticide sprays for managing Z. tau. In this study, we designed a bait station by integrating female-biased olfactory, visual, and gustatory elements, and a killing agent in a wax-matrix. Our results showed that the wax-matrix integrated with spinetoram showed the highest toxicity to immature and mature Z. tau females. Furthermore, the color and shape of the spinetoram bait station significantly influenced its attractiveness and toxicity to female Z. tau. Green sausage-shaped exteriors were the most effective color and shape examined. Subsequent experiments showed a length-dependent effect on mortality and visiting frequencies of Z. tau females when the bait stations were 9-13 cm long. The addition of the olfactory stimulus of 5% ammonium acetate to the bait station attracted a higher number of mature Z. tau females than the control. The killing efficacy of the weathered bait station was similar to that of the fresh station within an 8-week period (over 794 mm of rainfall). The bait station developed herein would provide new insight into the attract-and-kill strategy for Z. tau and alleviate the pressure of the actual management program for this pest.
黄瘿蚊（Zeugodacus tau）（双翅目：瘿蚊科）是一种重要的农业害虫，由于控制策略有限，目前主要通过使用杀虫剂来管理。诱捕站装置具有针对性，并且已成为一种基于行为的替代传统杀虫剂喷雾的方法，可用于管理黄瘿蚊。在这项研究中，我们设计了一种诱捕站，该诱捕站通过整合雌性偏爱的嗅觉、视觉和味觉元素以及蜡基质中的杀虫剂来实现。我们的结果表明，含有螺旋霉素的蜡基质对未成熟和成熟的黄瘿蚊雌性具有最高的毒性。此外，螺旋霉素诱捕站的颜色和形状显著影响其对雌性黄瘿蚊的吸引力和毒性。绿色香肠状的外部是检查过的最有效的颜色和形状。随后的实验表明，当诱捕站长 9-13 厘米时，对黄瘿蚊雌性的死亡率和访问频率有长度依赖性效应。在诱捕站中添加 5%乙酸铵的嗅觉刺激吸引了更多成熟的黄瘿蚊雌性，而对照组则没有。在 8 周的时间内（超过 794 毫米的降雨量），风化诱捕站的杀灭效果与新鲜诱捕站相似。本文开发的诱捕站将为黄瘿蚊的引诱和杀灭策略提供新的思路，并减轻该害虫实际管理计划的压力。
