Abstract
Feeding, reproduction and development of Amblyseius sojaensis EHARA on Panonychus citri (MCGREGOR), Tetranychus kanzawai KISHIDA and tea pollen was investigated. When A. sojaensis fed on the spider mites, the egg production of this phytoseiid mite was so sparse that the next generation did not develop. But when tea pollen was provided as food, A. sojaensis laid many eggs so that in 10 days the population increased.The eggs of A. sojaensis were laid on pollen or fibrous matter and similar appearing material on the lower surface of leaves. When the mites were reared on tea pollen for long periods, clusters of eggs and chorions were observed.
