Data obtained in 2005 and 2006 both from captures with yellow sticky traps and from periodic direct samplings on flowers showed that Aeolothrips intermedius Bagnall (Thysanoptera Aeolothripidae) is, among its congenera, the species most frequently present in phytocenoces of northwestern Tuscany. It shows a predatory behaviour, and completes in Tuscany 3-4 generations a year, with 3 peaks of presences, in June, in July and in August. During 2006, by rearing this species under laboratory conditions (mean temperature in May 23 ± 2 °C and in June 27 ± 2 °C and natural photoperiod) it was found that the duration of embryonic development was 6.8 and 3.7 days respectively in May and in June; duration of the first larval instar was 3.2 days in May and 2.4 in June; duration of the second larval instar was 5.4 and 4.1 days and finally, duration of the pre-pupa and pupa was totally 6.2 days in May and 5.6 in June. Life cycle duration (egg-adult) takes 21.6 ± 2.2 days in May and 15.7 ± 1.6 days in June.
