A Preliminary Report on the Tetranychidae (Acarina) of Brazil
Annals of the Entomological Society of America, 1970Thirty-five species of Brazilian Tetranychidae are discussed, of which 7 are new: Oligonychus steinhaueri , Schizotetranychus rhynosperus , Eotetranychus nigrens , Platytetranychus spatulatus , P. elongatus , Mononychus mcgregori , and Tetranychus armipenis . The genus Acostanychus Livschitz is synonymized under Atrichoproctus Flechtmann (NEW SYNONYMY).

Population Dynamics of Tetranychus Kanzawai (Acari: Tetranychidae) on Hydrangea
Experimental & Applied Acarology, 2000The seasonal occurrence of Tetranychus kanzawai Kishida populations on hydrangea (Hydrangea macrophylla) was studied at two different localities in Ibaraki, Japan, during a three-year period. There were two types of seasonal population trends: one with a population peak from May to June, and the other with the spring peak in June and the autumn peak in

The species diversity and some features of ecology of tetranychid mites of the Black Sea Biosphere Reserve were investigated. As a total, 20 species and 11 genera of spider mites were found on the 58 green plantings. Some features of distribution and trophic specialization of tetranychid mites were established in this reserve.

The carotenoid pigments of Oligonychus bessardi Gutierrez (Acari: Tetranychidae)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976Abstract 1. 1. Eleven carotenoids were present on thin layer chromatograms of extracts from the spider mite Oligonychus bessardi. 2. 2. The following carotenoids were isolated and identified: α-carotene, β-carotene, lutein, lutein epoxide, violaxanthin, neoxanthin, hydroxyechinenone, phoenicoxanthin and astaxanthin. 3. 3.

The carotenoid pigments of Schizonobia sycophanta Womersley (Acari: Tetranychidae)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1974Abstract 1. 1. Nine carotenoids were isolated and identified from the spider mite Schizonobia sycophanta . 2. 2. Besides the unaltered plant carotenoids β-carotene, lutein, lutein-5,6-epoxide, violaxanthin and neoxanthin, all taken in with the food, the mites contained the keto-carotenoids echinenone, 3-hydroxy-4-keto-β-carotene, 3-hydroxy-4,

Carotenoid metabolism in tetranychus urticae koch (Acari: Tetranychidae)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1974Abstract 1. 1. Besides the plant carotenoids α-carotene, β-carotene, lutein, lutein-5,6-epoxide, violaxanthin and neoxanthin, wild-type Tetranychus urticae was found to contain esterified 3-hydroxy-4-keto-β-carotene, 3-hydroxy-4,4′-diketo-β-carotene and astaxanthin. 2. 2. From the study of the carotenoid content of seven pigment mutants of
