ABSTRAKTungau laba-laba kanzawa (TLK), Tetranychus kanzawai Kishida (Acari: Tetranychidae) merupakan hama penting pada berbagai jenis tanaman di Indonesia. Pengendalian tungau ini umumnya dilakukan menggunakan akarisida, yang bisa menimbulkan dampak samping negatif. Salah satu alternatif cara pengendalian yang aman adalah dengan tungau predator. Penelitian ini bertujuan untuk mengetahui preferensi dan tanggap fungsional tungau predator Neoseiulus californicus McGregor (Acari: Phytoseiidae) terhadap beberapa stadia TLK. Penelitian dilakukan di laboratorium pada suhu ruang. N. californicus diberi mangsa telur dan nimfa TLK untuk mengetahui preferensinya. N. californicus juga diberi mangsa telur TLK pada beberapa tingkat kepadatan untuk mengetahui tanggap fungsionalnya. Imago betina dan deutonimfa N. californicus lebih memilih telur dibandingkan nimfa TLK. Jumlah telur yang dikonsumsi oleh imago betina dan deutonimfa N. californicus meningkat dengan meningkatnya kepadatan mangsa. Jumlah telur yang diletakkan imago betina N. californicus semakin meningkat dengan meningkatnya kepadatan mangsa. Waktu pencarian mangsa oleh imago betina dan deutonimfa N. californicus semakin cepat dengan meningkatnya kepadatan mangsa yang diberikan. Pada populasi mangsa yang rendah N. californicus bisa memangsa sesamanya.

ABSTRACTKanzawa spider mite (KSM), Tetranychus kanzawai 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 Neoseiulus californicus (Acari: Phytoseiidae) on several life stages of KSM. Experiments were conducted under laboratory conditions. N. californicus were supplied with nymphs and adults of KSM to know its preference. N. californicus were also supplied with KSM eggs at several densities to know its functional response. Adult females and deutonymphs of N. californicus preferred KSM eggs than nymphs as their prey. The number of eggs consumed by adult females and deutonymphs N. californicus increased with the increase of prey density. The number of eggs laid by adult females of N. californicus increased with the increase of prey density. Searching time of the predator became *Penulis korespondensi: Sugeng Santoso.
