Low-cost monitoring tools are needed to implement IPM in arable crops. YATLORf (Yf) traps baited with respective synthetic pheromone lures have proven to be a reliable tool for monitoring spp., Europe's most harmful soil pests. To optimize Yf use, we studied the effect of lure position in the trap and crop density on trap performance. Yf management detail was studied between 2000-2003 and 2014-2016 in various countries, with the traps being arranged in blocks. Each block contained one trap per treatment (i.e., lure position) under study. It was ascertained that lure attractant capacity can vary greatly with the lure's position in the trap and the extent of vegetation. Information for making practical decisions is given. The 'low' lure position is suitable for all species in all field conditions, and is the best choice for . Lures for need to be placed in the low position when the field has no or sparse vegetation cover. The 'high' lure position is unsuitable for and , and should be considered for some species only. There are no restrictions on position for catching , i.e., any position is suitable. Dense vegetation (e.g., wheat) reduced the Yf trap's potential for catching . Placing the trap just outside the field, or in a nearby field with bare/sparse vegetation, maintained the maximum catching potential. Vegetation density also influenced beetle sex ratio, with and females always found in traps placed in fields with bare or low-density vegetation. Our findings have made it possible to obtain consistent monitoring outputs and to begin studies on multi-baiting the same trap, which can significantly reduce monitoring costs.
在可耕地作物上实施综合虫害管理需要低成本的监测工具。用相应合成信息素诱饵诱捕的YATLORf（Yf）诱捕器已被证明是监测欧洲最有害的土壤害虫—— spp.的可靠工具。为了优化Yf诱捕器的使用，我们研究了诱捕器中诱饵位置和作物密度对诱捕性能的影响。2000年至2003年以及2014年至2016年期间，在不同国家对Yf诱捕器的管理细节进行了研究，诱捕器按区块布置。每个区块包含一个用于每种所研究处理（即诱饵位置）的诱捕器。已确定诱饵的吸引能力会因诱饵在诱捕器中的位置以及植被程度而有很大差异。给出了用于实际决策的信息。“低”诱饵位置适用于所有田间条件下的所有物种，是 的最佳选择。当田间没有或植被覆盖稀疏时， 的诱饵需要放置在低位。“高”诱饵位置不适用于 和 ，仅对某些物种应予以考虑。捕获 时对位置没有限制，即任何位置都合适。茂密植被（如小麦）会降低Yf诱捕器捕获 的潜力。将诱捕器放置在田外或附近植被光秃/稀疏的田地中可保持最大捕获潜力。植被密度也影响甲虫的性别比例，在植被光秃或低密度的田地中放置的诱捕器中总是能发现 和 的雌性个体。我们的研究结果使得能够获得一致的监测结果，并开始对同一诱捕器使用多个诱饵进行研究，这可显著降低监测成本。
