The California red scale, Aonidiella aurantii (Maskell), was first detected in citrus groves in Catalonia, Northern Spain, in
2000, and has since spread slowly and irregularly. New foci of infestation are currently found in citrus-growing areas of southern Tarragona. As Catalonia is the northernmost citrus growing area in Spain, between 2002 and 2009, A. aurantii population
dynamics and seasonal trends were studied in two citrus groves and compared with other regions and countries. The population dynamics showed that there were four male flights (including that of the overwintering generation): in May, mid June-mid
July, August and October, the most abundant being that of August (over 60% of the males captured during the year). The thermal constant estimated between male flights, using 11.7°C as the lower threshold temperature, was 611.8 ± 35.5 degree-days.
Three peaks of 1st and 2nd nymph instars were observed: in early June, late July-early August, and late September. The number
of crawlers captured on sticky tapes reached a first maximum on 27th May (± 1.85 days). The male flight abundance showed
a positive relationship between two consecutive generations, revealing the stability of A. aurantii populations.
