摘要：

The brownheaded leafroller (BHLR), Ctenopseustis obliquana (Walker) (Lepidoptera: Tortricidae) was reared on an artificial diet at seven constant temperatures. The mean life cycle at optimum rearing temperature of 20 +/- 1-degree-C was: egg development 8.7 days; larval period, M 37.4, F 41.2 days; pupal period, M 14.9, F 13.3 days; pupal weights, M50.5, F 68.2 mg; and a fecundity of 670 eggs per female. Estimated lower threshold temperatures and mean cumulative number of day-degrees for various stages of development were 7.8-degrees-C and 105D-degree for eggs, 5.2-degrees-C and 538D-degrees for larvae, and 7.2-degrees-C and 186D-degrees for pupa. Total mean day-degree accumulation from egg to adult was 829D-degree. These data were used to develop an efficient rearing management system embracing colony maintenance, storage manipulation, production, and quality assessment procedures.
