The role of different bait types and trap installation heights for an accurate trapping of flower chafer beetles (Coleoptera: Cetoniidae) is still poorly understand worldwide, especially in the Neotropical region. Therefore, in this study, we evaluated how the type of bait and trap installation height can influence flower chafer beetle sampling in the Amazon rainforest. For this, we sampled flower chafer beetles monthly from June to December 2019 in five Amazon forest fragments, in Juína, Mato Grosso, Brazil. In each collecting fragment, we installed aerial traps at different heights (i.e., 1.5, 4.5, 7.5, and 10.5 m above ground) and randomly baited with 300 ml of each of the following bait types: banana + sugarcane juice mixture; pineapple + sugarcane juice mixture; beer; or red wine. We collected 412 individuals belonging to 12 species of Cetoniidae beetles. Traps baited with pineapple + sugarcane juice mixture captured greater abundance and species richness of flower chafer beetles. Moreover, traps at 4.5, 7.5, and 10.5 m caught a similar number of individuals and species, and significantly more than traps at 1.5 m. Thus, our results provide evidence that for an accurate sampling of flower chafer beetle assemblages in tropical forests, traps baited preferably with a ripe fruit (e.g., pineapple) and sugarcane juice mixture should are installed at least 4.5 m above ground.

在亚马逊热带雨林中取样花金龟子甲虫(鞘翅目:Cetoniidae):诱饵类型和陷阱安装高度的作用

不同诱饵类型和诱捕器安装高度在准确诱捕金龟子甲虫(鞘翅目:Cetoniidae)方面的作用在世界范围内仍然知之甚少,尤其是在新热带地区。因此,在本研究中,我们评估了诱饵类型和陷阱安装高度如何影响亚马逊雨林中的金龟子甲虫采样。为此,我们从 2019 年 6 月到 2019 年 12 月每月在巴西马托格罗索州 Juína 的五个亚马逊森林碎片中对花龟甲虫进行采样。在每个收集片段中,我们在不同高度(即离地1.5、4.5、7.5和10.5 m)安装了空中诱捕器,并随机用300毫升以下诱饵类型中的每种诱饵进行诱饵:香蕉+甘蔗汁混合物;菠萝+甘蔗汁混合物;啤酒; 或红酒。我们收集了属于 12 种 Cetoniidae 甲虫的 412 个人。用菠萝 + 甘蔗汁混合物作为诱饵的陷阱捕获了更多的花金龟子甲虫和物种丰富度。此外,4.5、7.5 和 10.5 m 处的陷阱捕获的个体和物种数量相似,并且明显多于 1.5 m 处的陷阱。因此,我们的结果提供了证据,证明要对热带森林中的金龟子甲虫组合进行准确采样,最好将用成熟水果(例如菠萝)和甘蔗汁混合物作为诱饵的诱捕器安装在离地面至少 4.5 m 的地方。并且明显超过 1.5 m 处的陷阱。因此,我们的结果提供了证据,证明要对热带森林中的金龟子甲虫组合进行准确取样,最好将诱捕器以成熟的水果(例如菠萝)和甘蔗汁混合物作为诱饵,应安装在离地面至少 4.5 m 的地方。并且明显超过 1.5 m 处的陷阱。因此,我们的结果提供了证据,证明要对热带森林中的金龟子甲虫组合进行准确取样,最好将诱捕器以成熟的水果(例如菠萝)和甘蔗汁混合物作为诱饵,应安装在离地面至少 4.5 m 的地方。
