Melolontha hippocastani - study of female oviposition behavior, North-East France, 2019

During 2019 summer, we studied oviposition behavior of Melolontha hippocastani females. Therefore, we dug pits in forest and counted density of egg-laying and eggs in soil. In parallel, we discribed environmental conditions by measuring canopy openness, presence of a dense shrub layer and tree basal area (including shared basal area by each tree specie).

2019年夏季，我们针对栗山鳃金龟（Melolontha hippocastani）雌虫的产卵行为开展研究。为此，我们在林间开挖样坑，统计了土壤中产卵痕迹与卵粒的密度。同时，我们通过测定林冠开度、密灌层存在状况以及树木胸高断面积（含各树种的总断面积）来表征生境环境条件。
