最近，铃木果蝇 (Matsumura) 被引入美国西部生产樱桃 (Prunus avium (L.)) 的地区，导致需要在接近收获时实施基于杀虫剂的管理计划。由于出口市场对于进口水果上不同杀虫剂允许的最大残留限量（MRL）不一致，这些处理方法已成为问题。因此，根据美国环境保护局发布的标签以安全方式处理和收获的水果可能有资格出口到 MRL 低于美国的国家或尚未建立 MRL 的国家。该项目通过测量在收获开始前 7 或 21 天施用时六种杀虫剂的降解曲线来解决这个问题。根据这些测试的结果，我们提出了一系列可用于斑翅果蝇控制的杀虫剂，杀虫剂的施用次数和使用顺序取决于害虫压力以及施用和收获之间所需的天数。三种具有良好特性的杀虫剂包括高效氯氟氰菊酯、多杀菌素和马拉硫磷，它们使生产商能够将功效、水果易感性和抗性管理的原则结合起来，并且仍然允许将水果出口到所有主要出口市场。
The recent introduction of Drosophila suzukii (Matsumura) into regions of the western United States that produce cherries, Prunus avium (L.), has resulted in the need for insecticide-based management programs close to harvest. These treatments have become problematic because of inconsistencies among export markets regarding maximum residue limits (MRLs) that are allowed for different insecticides on imported fruit. As a result, fruit that was treated and harvested in a safe manner according to the U.S. label issued by the Environmental Protection Agency may or may not qualify for export to countries that have MRLs that are lower than those of the United States, or where MRLs have not yet been established. This project addresses this issue by measuring the degradation curves of six insecticides when applied at 7 or 21 d before the initiation of harvest. Based on the results of these tests, we propose a selection of insecticides that can be used for spotted wing drosophila control, with the number of applications and sequence of insecticides used dependent on pest pressure and the number of days required between application and harvest. Three insecticides with favorable characteristics include lambda-cyhalothrin, spinosad and malathion, which allow producers to incorporate the principles of efficacy, fruit susceptibility, and resistance management and still allows for the export of fruit to all major export markets.
