Knowledge of the mechanisms that regulate courtship and mating behavior in Psyttalia concolor (Szépligeti)-a koinobiont endophagous solitary parasitoid of the olive fruit fly, Bactrocera oleae (Rossi), and of other fruit flies-is essential to its mass rearing and management. Augmentative releases of P. concolor for olive fruit fly control started in the Mediterranean areas in the 1950s and still continue with limited success. We determined the influence of visual and chemical cues on courtship and mating behavior of this braconid and the possible effect of the mating status of males and females in the perception of these cues. Our results suggest that integration of visual and chemical stimuli are fundamental for mate location and courtship. Indeed, the optimal response of the male was achieved when physical and chemical cues were simultaneously presented and vision and olfaction worked synergistically.
了解调控 Psyttalia concolor（Szépligeti）——一种橄榄果实蝇 Bactrocera oleae（Rossi）及其它果实蝇的兼性内寄生性独居寄生蜂——求偶和交配行为的机制对于其大规模饲养和管理至关重要。自 20 世纪 50 年代起，在地中海地区开始进行 P. concolor 的增殖释放以控制橄榄果实蝇，但收效甚微。我们确定了视觉和化学线索对这种长尾小蜂求偶和交配行为的影响，以及雌雄个体交配状态对这些线索感知的可能影响。研究结果表明，视觉和化学刺激的整合对于寻找配偶和求偶至关重要。事实上，当同时呈现物理和化学线索，并且视觉和嗅觉协同作用时，雄性的最佳反应得以实现。
