Melolontha hippocastani - study on 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，我们针对欧洲栗鳃金龟（Melolontha hippocastani）雌虫的产卵行为开展了研究。为此，我们在林地内开挖样坑，对土壤中的产卵位点密度与卵粒密度进行了计数统计。与此同时，我们通过测定林冠开度、密灌层存在情况以及林木胸高断面积（含各树木物种的共享断面积）来描述环境条件。
