Karyotypes and sex-determination in spider mites (Tetranychidae)
Genetica, 1967The chromosomes of 13 species of spider mites (Tetranychidae) are determined using the aceto-orcein squash technique in order to establish the haplo-diploid sex-determination. 12 species showed the existence of haploid and diploid eggs:Neotetranychus rubi (Tragardh) with 7 and 14 chromosomes;Eurytetranychus buxi (Garman) with 5 and 10;Bryobia ...

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,
