Little evidence was found that most scents attracted wild pigs.
几乎没有证据表明，大多数气味会吸引野猪。
Wild pigs (Sus scrofa) are a prolific invasive species throughout many regions of the world that cause extensive economic and environmental damage. Trapping is a common strategy for reducing their populations with baits (i.e., food) and attractants (e.g., scents) used to lure wild pigs into traps. However, there is little information on which scent attractants may attract wild pigs more readily and rapidly across regions and seasons. We examined 60 scent attractants for wild pigs that could be used to increase trapping success across three seasons (winter, spring, and fall) and in two geographic regions, including a warm and semi-arid rangeland (South Texas, USA) and a warm and moist mixture of upland and bottomland forests (South Carolina, USA).
野猪（Susscrofa）是世界上许多地区的一种多产的入侵物种，会造成广泛的经济和环境破坏。诱捕是一种常见的策略，通过诱饵（如食物）和引诱剂（如气味）引诱野猪进入诱捕器来减少它们的数量。然而，关于哪种气味引诱剂可以更容易、更迅速地在不同地区和季节吸引野猪的信息很少。我们研究了60种野猪气味引诱剂，这些引诱剂可用于在三个季节（冬季、春季和秋季）和两个地理区域提高诱捕成功率，包括温暖和半干旱的牧场（美国德克萨斯州南部）和温暖和潮湿的高地和低地森林（美国南卡罗来纳州）。
We found little evidence that most scents attracted wild pigs. Only strawberry extract and creosote bush oil increased the probabilities of visitation, and only in Texas during the fall season. No other scents attractants performed better than the control (i.e., no scent) in both study locations. More wild pigs visited sites during the fall season regardless of scent attractant used. The location of a site mattered more than which attractant was used, and a post hoc analysis revealed that distances to roads and water flowlines (i.e., permanent or ephemeral drainages, streams, and rivers) increased the probabilities of visitation during some seasons.
我们发现并不是大多数气味都能吸引野猪。只有草莓提取物和杂酚油灌木油增加了诱捕的机会，并且仅在德克萨斯州的秋季。在两个研究地点，没有其他气味引诱剂比对照组表现更好（即无气味）。无论使用何种气味引诱剂，更多的野猪在秋季访问了这些地点。诱捕点的位置比使用哪种引诱剂更重要，事后分析表明，距离道路和水流线（即永久或短暂的排水沟、溪流和河流）的距离增加了某些季节的访问概率。

We conclude there was no panacea scent that was more effective than controls in attracting wild pigs across regions and seasons. Placement of sites and seasonality were more important for attracting wild pigs, suggesting the location of traps or bait sites may be more important than the specific attractants used for management activities. Future research should include monitoring movements of wild pigs relative to scent attractants and evaluation of baits (e.g., food-rewards) for drawing wild pigs to sites.
我们得出结论，在跨地区和跨季节吸引野猪方面，没有比对照更有效的气味了。诱捕点的位置和季节性对吸引野猪更为重要，这表明陷阱或诱饵地点的位置可能比特定引诱剂更为重要。未来的研究应包括监测野猪相对于气味引诱剂的移动，以及评估将野猪吸引到现场的诱饵（例如食物奖励）。
