Abstract

Abstract Because bark and ambrosia beetles fly during their dispersal and host location processes, their flight height is important for assessing their host selection strategy. There is no consensus regarding the height of their dispersal flight in forests, and their method of approaching trees is unclear. This is also the case for Platypus quercivorus (Murayama) (Coleoptera: Platypodinae), which causes Japanese oak wilt by transporting a pathogenic fungus. To clarify the vertical distribution of the flying population of P. quercivorus inside the host tree canopy, interception traps were set up at heights of 1–9 m from the ground near the main trunk of eight host trees, Quercus serrata Thunberg (Fagaceae). Captured beetles were collected between July and October 2022. Hole-boring activities were observed on all trees during the season, and beetles were captured at all heights from 1 to 9 m. Beetle capture probability increased with a decrease in height, and the number of captured beetles increased with a decrease in distance from the main trunk. However, the trap design in this study could not capture individuals coming directly above and must be addressed to elucidate their method of approaching their host plant.

在宿主树冠内捕获橡树甲虫

由于树皮甲虫和凤花甲虫在其散布和寄主定位过程中飞行，因此它们的飞行高度对评估它们的寄主选择策略很重要。关于它们在森林中分散飞行的高度没有共识，它们接近树木的方法也不清楚。这种情况也发生在Murayama鸭嘴兽(鞘翅目:鸭嘴兽科)身上，鸭嘴兽通过运输一种致病真菌导致日本橡树枯萎。为了明确栎科栎科栎(Quercus serrata Thunberg) 8株栎主树干附近离地面1 ~ 9 m高度的拦截器，确定了栎科栎在宿主树冠内的垂直分布。捕获的甲虫是在2022年7月至10月期间收集的。季节内所有树木均有钻孔活动，在1 ~ 9 m高度均捕获到甲虫。捕获甲虫的概率随高度的降低而增加，捕获甲虫的数量随距离主干道的减小而增加。然而，本研究中的诱捕器设计不能捕获直接来自上方的个体，必须阐明它们接近寄主植物的方法。
