Abstract Intensive chayote cultivation in Reunion almost disappeared in the 2000s due to significant yield losses from fruit flies attacking this historically important crop (Dacus ciliatus, Zeugodacus cuurbitae and Dacus demmerezi). Since the late 2000s, the adoption of agroecological crop protection practices have led to the effective management of fruit fly populations, a significant reduction in pesticide use, an increase in chayote production and plantations, and the development of organic production. To assist in fruit fly management, a qualitative model which simulates fruit fly damage to chayote crops, known as IPSIM-chayote, was developed, providing satisfactory prediction results. It has a user-friendly interface and is now available free of charge online, in three languages (French, English and Spanish): https://pvbmt-apps.cirad.fr/apps/ipsim-chayote/?lang=en. The IPSIM-chayote modeling platform can be used by farmers as a tool to simulate fruit fly damage to their crops and also as a decision-making tool for their agricultural practices. The model can be used as a training resource in agroecological crop protection. Public authorities and local government can use it as a tool in planning and forecasting agricultural development. Finally, researchers can use it as a prediction tool and a resource for the exchange of information, allowing them to review scientific knowledge or identify new, relevant research areas suited to the context and challenges. IPSIM-chayote can be considered as a forum for exchange and can stimulate collaborative work between individuals. It is a flexible model, as it allows variables to be added. IPSIM-chayote is the first qualitative model developed for crop pests in a tropical environment. It could serve as a basis for the development of other similar models simulating crop pest incidence, thus contributing significantly to the development of agroecological crop protection.

留尼汪佛手瓜果蝇伤害的定性建模：开发和转移给用户

摘要 由于果蝇攻击这种具有历史意义的作物（Dacus ciliatus、Zeugodacus cuurbitae 和 Dacus demmerezi）造成重大产量损失，留尼汪岛的佛手瓜集约化种植在 2000 年代几乎消失。自 2000 年代后期以来，农业生态作物保护措施的采用导致了果蝇种群的有效管理、农药使用的显着减少、佛手瓜生产和种植园的增加以及有机生产的发展。为了协助果蝇管理，开发了一种模拟果蝇对佛手瓜作物的损害的定性模型，称为 IPSIM-佛手瓜，提供了令人满意的预测结果。它有一个用户友好的界面，现在可以免费在线使用三种语言（法语、英语和西班牙语）：https://pvbmt-apps.cirad。fr/apps/ipsim-佛手瓜/?lang=en。IPSIM-佛手瓜建模平台可被农民用作模拟果蝇对其作物造成的损害的工具，也可用作其农业实践的决策工具。该模型可用作农业生态作物保护的培训资源。公共当局和地方政府可以将其用作规划和预测农业发展的工具。最后，研究人员可以将其用作信息交换的预测工具和资源，使他们能够回顾科学知识或确定适合背景和挑战的新的相关研究领域。IPSIM-佛手瓜可以被视为一个交流论坛，可以激发个人之间的协作工作。这是一个灵活的模型，因为它允许添加变量。IPSIM-佛手瓜是第一个针对热带环境中作物害虫开发的定性模型。它可以作为开发其他模拟作物病虫害发生率的类似模型的基础，从而对农业生态作物保护的发展做出重大贡献。
