A total of 40 phytoseiid species has been reported from Chile, including the two species (Neoseiulus californicus (McGregor) and Phytoseiulus persimilis (Athias-Henriot) most widely used worldwide for the biological control of the two-spotted spider mite, Tetranychus urticae Koch (Tetranychidae). In this paper we report nine other species found in new collecting conducted since 1989, including three new species: Amblyseius herbicolus (Chant), Amblyseius tamatavensis Blommers, Arrenoseius robertogonzalezi Trincado & Martin n. sp., Neoseiulus anonymus (Chant & Baker), Neoseiulus bicaudus (Wainstein), Neoseiulus viticolus Trincado & Martin n. sp., Metaseiulus (Metaseiulus) camelliae (Chant & Yoshida-Shaul), Metaseiulus (Metaseiulus) neoflumenis Moraes & Kreiter and Metaseiulus (Metaseiulus) relictus Trincado & Martin n. sp.. Chileseius camposi Gonzalez & Schuster, 1962 is redescribed, and a list of all species presently known from Chile and a key to help in their separation are given. A new name, Proprioseiopsis kargi Trincado nom. nov., is a replacement name for Proprioseiopsis globosus Karg, 1976, a junior homonym of Proprioseiopsis globosus (Gonzalez & Schuster, 1962).

Three predators Scolothrips sexmaculatus Pergande, Phytoseiulus persimilis Athias - Henriot and Stethorus punctillum Weise were used to control two-spotted spider mite, Tetranychus urticae Koch on potted bean plants. Mite population increased exponentially on the untreated plants, but on the predator treated plants, increase of mite population was checked and remained within minimum number. Early release of predator checked the mite population earlier and kept it lower than on late released plants. All the three predators may be used as bio-control agents against two-spotted spider mite. Key words: Control, Tetranychus urticae, Scolothrips sexmaculatus, Phytoseiulus persimilis, Stethorus punctillum and bio-control agents.   doi:10.3329/ujzru.v27i0.1954 Univ. j. zool. Rajshahi Univ.

Two Spotted Spider Mite

The two-spotted spider mite Tetranychus urticae is a dangerous polyphagous pest of agricultural and ornamental plants. In a commercial greenhouse treated with acaricides or biological control using predatory mite Phytoseiulus persimilis individual varieties of roses differed significantly in terms of the average annual infestation by the pest mite. On the poorly populated rose varieties, the biological control agent application was more effective as compared to the acaricides. To effectively control the pest, the required predatory mite rates were 4.6–8.7 times higher on varieties with a minimal spider mite infestation (Aqua and Deep Water) as compared to the maximal pest infestation (Heaven and Brazil).
