On the leaf disc of fruit vegetables (cucumber, sweet pepper, tomato, egg plant, oriental melon), it has been evaluated that the capability of four predatory mites (Amblyseius swirskii Athias-Henriot, Neoseiulus barkeri (Hughes), N. cucumeris (Oudemans), N. californicus (McGregor)) to prey on the eggs of Bemisia tabaci (Gennadius) and to lay own eggs. The most aggressive mite was A. swirskii which had consumed about 9~12 eggs in a day. The quantity of eggs consumed by N. barkeri, N. cucumeris and N. californicus was about 6~9, 4~6 and 1~4, respectively. The most productive mite was also A. swirskii which had laid about 1.2~1.9 eggs in a day. The others could not lay more than 0.5 eggs in a day.
