【Background】Procecidochares utilis Stone (Diptera: Tephritidae), an obligatory parasite of the invasive plant, Eupatorium adenophorum Spreng, can inhibit the growth and development of its host plant, and can effectively control its spread of E.adenophorum. 【Method】P.utilis were artificially reared at eight constant temperatures (5 ℃, 10 ℃, 15 ℃, 20 ℃, 25 ℃, 30 ℃, 35 ℃ and 40 ℃) and different nutrients (sugar, honey and glucose) at concentrations of 2.5%, 5%, 10% and 20%. The life span of P.utilis adults were recorded. 【Result】Adults, both males and females lived longest at 5 ℃ (35.06 d and 35.26 d, respectively)， but both males and females lived shortest at 40 ℃ (0.16 d). Adult males fed on 20% glucose solution lived the longest (30.0 d), while adult females fed on 20% suger solution lived longest (19.20 d). 【Conclusion and significance】There was a negative correlation between adult P.utilis life span in the range of 5~40 ℃. The life span of female and male P.utilis adults could significantly be prolonged by providing sugar, honey and glucose. Our results provide a theoretical basis for P.utilis indoor mass rearing for field release.
