| Sumario: | Kanzawa spider mite (KSM), <em>Tetranychus kanzawai</em> Kishida (Acari: Tetranychidae) is an important pest on many crops in Indonesia. Generally, farmers use acaricide to control this mite, which may cause negative side effects. One of the alternative control methods is the use of predatory mite. This research was done to determine prey preference and functional response of predatory mite<em> Neoseiulus californicus</em> (Acari: Phytoseiidae) on several life stages of KSM. Experiments were conducted under laboratory conditions. <em>N. californicus</em> were supplied with nymphs and adults of KSM to know its preference.<em> N. californicus</em> were also supplied with KSM eggs at several densities to know its functional response. Adult females and deutonymphs of<em> N. californicus</em> preferred KSM eggs than nymphs as their prey. The number of eggs consumed by adult females and deutonymphs <em>N. californicus</em> increased with the increase of prey density. The number of eggs laid by adult females of <em>N. californicus</em> increased with the increase of prey density. Searching time of the predator became faster with the increase of prey density.<em> N. californicus</em> showed cannibalism under low density of prey. |
