Abstract Successful fruit fly control requires effective monitoring to make pest management decisions. Ceratitis capitata (Medfly) is typically monitored in Tunisia with parapheromone commercialised as trimedlure (TM). Chemical treatment is applied when the economic threshold (3 flies/trap/day) is reached. In this study, C. capitata populations in a commercial citrus orchard captured in McPhail traps baited with TM or enriched ginger oil (EGO) were compared over two seasons (2011 and 2012). Females of C. capitata were not attracted to TM or EGO. Trimedlure was significantly more attractive to C. capitata males than EGO under low and high population densities over sampling dates. The TM used in McPhail traps was adequate to attract male medflies in citrus orchards under a wide range of Medfly population levels. The use of the best attractant can help to make control decisions when population levels of flies are low, thus preventing unnecessary application of insecticides and/or other control methods.

在柑橘园中使用trimedlure 与富集姜油检测Ceratitis capitalta Wiedemann（双翅目：实蝇科）

摘要 成功的果蝇控制需要有效的监测才能做出虫害管理决策。在突尼斯，通常使用商品化为三甲基脲 (TM) 的辅助信息素进行监测。当达到经济阈值（3 只苍蝇/陷阱/天）时，应用化学处理。在这项研究中，在两个季节（2011 年和 2012 年）中比较了用 TM 或浓缩姜油 (EGO) 诱饵的 McPhail 陷阱捕获的商业柑橘园中的 C. capita 种群。C. capita 的雌性不会被 TM 或 EGO 所吸引。在采样日期的低和高人口密度下，Trimedlure 对 C. capita 雄性比 EGO 更具吸引力。McPhail 陷阱中使用的 TM 足以吸引柑橘园中各种地中海果蝇种群水平下的雄性地中海果蝇。
