Title: Abundance and population of Acaphylla theavagrans Kadono ( Acari:. Eriophyidae ) in some varieties of tea plants and a report on its new predator (Amblyseius WomersleyiSchicha ).
Abstract: Summary Abundance and variation of population density of the tea rust mite, Acaphylla theavagrans Kadono (Acari: Eriophyidae) in ten varieties of tea, Camellia sinensis were studied. The mite population density was higher on the lower surface than on the upper surface, and this tendency was greater on young leaves than on old leaves. The total number of mites per leaf was higher on young leaf than on old one. The mite density per unit area (4.7 cm sq.) of young leaf differed significantly among the different varieties. Amblyseius womersleyi Schicha (Acari: Phytoseiidae) is found, as an effective predator ofA. theavagrans in the laboratory and this is the first report from Japan onA. womersleyi as a predator of the tea rust mite.
