The most effective odour attractant for G. brevipalpis Newstead, namely a combination of octenol released at c. 9.1 mg/h, 4-methyl phenol released at c. 15.5 mg/h and acetone released at c. 350 mg/h, when used together with the smallest recommended colour target (as determined in previous studies), namely a 1.75 m wide x 1 m high black/pthalogen-blue/black target, was evaluated for the control of G. brevipalpis and G. austeni Newstead. This combination increased the catches of G. brevipalpis by 3.5 fold when compared to the number of those caught on a 1.5 m wide x 1 m high black target baited with a synthetic ox-odour as was used in a trial to control this species in the Hluhluwe-Umfolozi Game Reserve in 1992. There was an indication that odour (olfaction) plays a far more important role in attracting G. brevipalpis than does colour (vision). For G. austeni visual attraction appears to play the major role as the odours used were relatively unattractive to them. The odour-baited target should, however, attract G. austeni in sufficient numbers (visually) to achieve control to the fly.
针对短须库蠓（Newstead）最有效的气味引诱剂，即约每小时释放9.1毫克的辛醇、约每小时释放15.5毫克的4-甲基苯酚和约每小时释放350毫克的丙酮的组合，与最小推荐颜色目标（如先前研究中所确定），即一个宽1.75米、高1米的黑色/酞菁蓝/黑色目标一起使用时，对短须库蠓和奥氏库蠓（Newstead）的防治效果进行了评估。与1992年在Hluhluwe-Umfolozi野生动物保护区用于防治该物种的试验中，在一个宽1.5米、高1米的用合成牛气味诱饵的黑色目标上捕获的数量相比，这种组合使短须库蠓的捕获量增加了3.5倍。有迹象表明，气味（嗅觉）在吸引短须库蠓方面比颜色（视觉）发挥着重要得多的作用。对于奥氏库蠓，视觉吸引似乎起主要作用，因为所使用的气味对它们相对没有吸引力。然而，用气味诱饵的目标应该能（在视觉上）吸引足够数量的奥氏库蠓，以实现对这种苍蝇的防治。
