Abstract：
BACKGROUND: An innovative version of the sterile insect technique (SIT) for pest control, called boosted SIT, relies on the use of sterile males coated with a biocide to control a target wild pest population of the same species. The objective of the present study was to assess the relevance of such technology to control the fruit fly Bactrocera dorsalis and fruit losses in mango orchards using. An agent-based simulation model named BOOSTIT was used to explore the reduction of fruit losses thank to sterile male fruit flies control and economic benefits according to different strategies of sterile male release. The simulation considered a landscape of 30.25 ha made up of four mango orchards.
RESULTS: The SIT and the boosted SIT reduced fruit losses when releases were made before the mango fruiting period. According to model simulations, releases should be performed at least seven times at 2-week intervals and with a sterile/wild male ratio of at least 10:1. Considering the benefit/cost ratio (BCR), few releases should be done with a late start date. The BCR showed economic gains from the two control methods, the number of saved fruits and BCR being higher for SIT.
CONCLUSIONS: Our simulations showed that SIT would have better results than the boosted SIT to contribute to an effective control of Bactrocera dorsalis at the scale of a small landscape. We highlight the need for laboratory studies of other types of pathogen to find a suitable one with higher incubation time and lower cost. © 2024 Society of Chemical Industry.

摘要：
背景：用于病虫害控制的不育昆虫技术（SIT）的创新版本，叫做增强SIT，依靠使用涂有杀菌剂的不育雄性来控制同一物种的目标野生害虫种群。本研究的目的是评估这种技术在控制果蝇中的相关性。使用背实菌和芒果果园的果实损失。使用基于代理的模拟模型BOOSTIT，根据不同的不育雄性释放策略，探索由于不育雄性果蝇的控制和经济效益，减少了果实损失。模拟考虑了由四个芒果园组成的30.25公顷景观。
结果：当在芒果果期之前进行释放时，SIT和增强的SIT减少了果实损失。根据模型模拟，释放应以2周的间隔进行至少7次，并且不育/野生雄性比例至少为10：1。考虑到收益/成本比(BCR)，很少的版本应该在较晚的开始日期完成。BCR显示了两种控制方法的经济收益，SIT保存的水果数量和BCR较高。
结论：我们的模拟表明，SIT比增强的SIT具有更好的结果，有助于在小景观范围内有效控制背软杆菌。我们强调需要对其他类型的病原体进行实验室研究，以找到具有较高孵育时间和较低成本的合适病原体。©2024化学工业学会。
