Abstract
On the young leaves, shoots, and buds of Cayratia japonica (Thunb.) Gagnep. (Vitaceae), we observed nutritious bodies called pearl bodies and hypothesized that they are utilized by generalist predators as alternative foods. Some ambulate organisms consume pearl bodies in the wild and the predatory mite Euseius sojaensis (Ehara) (Acari: Phytoseiidae) was considered as a primary candidate. Pearl bodies promoted E. sojaensis settlement on C. japonica leaves and E. sojaensis could prey on the phytophagous mite Tetranychus kanzawai Kishida (Acari: Tetranychidae) when the predators settle on a leaf before the prey. In addition, the presence of pearl bodies did not reduce predation of E. sojaensis on T. kanzawai. This was seemingly because food quality of T. kanzawai was higher than pearl bodies. These results implied that pearl bodies on C. japonica leaves are utilized by E. sojaensis as alternative foods.
