“…Stethorus japonicus was induced into reproductive diapause with day lengths shorter than 13 h at 18°C (Mori et al, 2005). Species with large geographical ranges that include both temperate and subtropical climates may hibernate in the colder area but not in the warmer (Collyer, 1964;Kaylani, 1967). For example, S. punctum diapauses in Pennsylvania (Colburn and Asquith, 1971;Colburn, 1971) and in Washington state (Horton et al, 2002), but is active year round in southern California .…”

The Stethorini are unique among the Coccinellidae in specializing on mites (principally Tetranychidae) as prey. Consisting of 90 species in two genera, Stethorus and Parasthethorus, the tribe is practically cosmopolitan. The Stethorini are found in a diverse range of habitats, including many agricultural systems such as pome and stone fruits, brambles, tree nuts, citrus, avocadoes, bananas, papaya, palms, tea, cassava, maize, strawberries, vegetables, and cotton, as well as ornamental plantings, grasslands, forests, and heathlands. Tetranychid mite outbreaks became common in many agricultural systems only after World War II, when widespread use of broad-spectrum insecticides increased. Stethorini were initially appreciated only for their ability to suppress severe outbreaks of tetranychid populations. However, research on their prey searching behaviors reveals that Stethorini use visual and olfactory stimuli to locate small mite colonies in patchy distributions, and can be very effective in regulating their prey at low densities. Moreover , acariphagous coccinellids colonize mite outbreaks earlier, and consume more pest mites, than many other mite predators. Key to the use of coccinellids in conservation biological control programs is the provision of overwintering habitats and refuges from pesticides in and near cropland. When these conditions are fulfilled, Stethorini often play important roles in maintaining suppression of tetranychid populations. Examples of successful biological mite control with Stethorini include apple orchards in Pennsylvania, USA, and citrus in Asia, and the unintended disruption of a tetranychid-based biological control program for the invasive woody weed, gorse, in Australia and New Zealand. The systematics and taxonomy of this group is challenging with many cryptic species, and molecular diagnostic tools are sorely needed. How best to utilize their mite-suppressive potential in diverse settings requires better knowledge of their requirements including utilization of alternative foods, refuges for dormancy and from nonselective pesticides , and host-finding mechanisms.

“…Para alguns estigmeídeos, os eriofiídeos são preferidos como recurso alimentar na falta dos tetraniquídeos (SANTOS, 1991 Baker, 1945 (Tenuipalpidae). Algumas espécies de Agistemus são de importância no controle de tetraniquídeos (COLLYER, 1964;LORENZATO et al, 1986;FERLA & MORAES, 1998 (BAKER, 1970).…”

ABSTRACT. Diversity and population fluctuation of mites (Acari) in blackberry (Rubus fruticosus, Rosaceae) in the state of Rio Grande do Sul, Brazil. Mites of the families Eriophyidae, Tarsonemidae and Tetranychidae are considered of economic importance in the blackberry (Rubus fruticosus, Rosaceae), raspberry and other small fruit crops. This study was conducted from November of 2001 to October of 2003 on Brazos, Caigangue and Tupy cultivars in Ilópolis municipality, state of Rio Grande do Sul, to describe the mitefauna and its population fluctuation in blackberry crops. A total of 36,094 mites belonging to 12 families was collected. Most of the mites belong to Diptilomiopidae (80.9%) and Tetranychidae (13.9%), composed predominantly of phytophagous species. Chakrabartiella sp. (Diptilomiopidae) was the most abundant species, followed by Neotetranychus asper Feres & Flechtmann, 2000 (Tetranychidae). Stigmaeidae (2.1%) and Phytoseiidae (0.4%) were the most common families of predaceous mites, and Agistemus brasiliensis Matioli, Ueckermann & Oliveira, 2002 (Stigmaeidae) and Typhlodromalus aripo DeLeon, 1967 (Phytoseiidae) the most common predaceous species.

“…Unpigmented larvae of S. bifidus and S. griseus can be r:ecognised by the more elongate narrower maxillary and labial palps and longer posterior setae on the mentum-submentum of S. bifidus, as well as differences in the number and arrangement of apical hairs on the tibio-tarsi. Collyer (1964) noted both light and dark coloured eggs and larvae of "S. bifidus". However, later material from 1966 and 1967 placed by her in these categories were not conspecific.…”
