Details were determined for the life hi story or the phytoseiid mite, Amblyseius cucumeris, with first-instar western flower thrips, Frankliniella occidentalis, as prey. A. cucumeris completed development in 11.09, 8.74 and 6.25 days at 20, 25 and 30°C respectively. This is slightly longer than reported for A. cucumeris by other authors using eggs of Tetranychus mites as prey. The mean egg production was 1.5 ± 0.99 eggs per day. In cold storage tests, after 10 weeks, 63% or A. cucumeris survived at 9°C. 1.2% survived at 2°C and 0°C survived at -8°C.
