In Tetranychus spider mites (Acari: Tetranychidae), diapausing females have a conspicuous orange body colour, which is used as an indicator of diapause induction in many laboratory studies. However, to which extent body colour reflects reproductive activity is scarcely investigated. In this study, we investigated the relationship between body colour, reproductive arrest, and food intake in the inbred strain of T. pueraricola individually reared at 20 A degrees C with a 10:14 h light: dark photoperiod. Our results showed that (1) body colour is a good indicator of reproductive arrest 11 days after adult emergence but does not completely reflect reproductive status at an earlier age; (2) even orange females intermittently feed, and the arrest of feeding comes after the change in body colour; and (3) reproducing females have a higher risk of death than non-reproducing females. These results suggest that measurement of diapause incidence by body colour alone may miss the variation in reproductive status in early adult life.
