Fruit flies (Diptera: Tephritidae) are considered to be major pests of mango (Mangifera indica) worldwide. Their management, with an increasing focus on replacing synthetic pesticides with alternative pest control methods, is a challenging issue. A study was carried out from 2015 to 2017 in Reunion Island under field conditions in order to characterize the incidence of fruit flies on mango production and to link fruit fly infestation with fruit maturity and fly pressure. Mango fruits were mainly infested by Bactrocera zonata. Few fruits were infested by Ceratitis quilicii, and even fewer by Ceratitis capitata. Infestation increased as fruits ripened. Less than 4% of the fruits were infested at the green, green-mature and early yellow-point stages. Infestation increased to 10–11% at later yellow-point stages, and reached 14–16% at ripe and overripe stages. Fruit infestation was closely related to changes in the peel texture (firmness, in particular) and chlorophyll fluorescence of the fruit as it ripened. Whereas variability in fruit fly abundance in traps was observed between orchards and years, it did not clearly explain variability in fruit infestations, which was mostly explained by variability in fruit maturity. The study suggests that fruit fly trapping is not adequate to assess infestation risk or to guide management decisions, but instead provides evidence that fruit fly damage could be reduced by adjusting harvest timing, especially by harvesting fruits at the green-mature stage or at the yellow-point onset.

果蝇（双翅目：蝇科）被认为是全世界芒果（Mangifera indica）的主要害虫。他们的管理越来越注重用替代的虫害控制方法替代合成农药，这是一个具有挑战性的问题。2015年至2017年，在留尼汪岛的田野条件下进行了一项研究，以表征果蝇在芒果生产中的发生率，并将果蝇侵染与果实成熟度和果蝇压力联系起来。芒果果实主要受带状小实蝇（Bactrocera zonata）侵染。很少有水果被quietitis quilicii侵染，甚至更少被Capitata capitata侵染。随着果实成熟，侵害增加。在绿色，绿色成熟和早期黄点阶段，只有不到4％的水果被侵染。在后期的黄点阶段，侵扰增加到10-11％，而在成熟和成熟阶段则达到14-16％。果实侵染与果实成熟时果皮质地（尤其是硬度）和叶绿素荧光的变化密切相关。尽管在果园和年份之间观察到陷阱中果蝇丰度的变化，但它并不能清楚地解释水果侵染的变化，这主要是由水果成熟度的变化解释的。该研究表明，果蝇诱捕不足以评估侵染风险或指导管理决策，而是提供证据表明可以通过调整收获时机来减少果蝇的危害，
