Two Spotted Spider Mite

The two-spotted spider mite, Tetranychus telarius (L.), is a well known pest of many plants in greenhouses. It is notoriously difficult to conarol, especially when resistant populations develop, and usually requires frequent acaricidal treatment during the growing season. Biological control has sometimes been suggested in view of the success that was achieved by this method against other greenhouse pests and because the environment is controllable to some extent, but only a few attempts have been made.

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).

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).
