Abstract：
Drosophila suzukii represents one of the major agricultural pests worldwide. The identification of safety and long-lasting tools to suppress its populations is therefore crucial to mitigate the environmental and economic damages due to its occurrence. Here, we explore the possibility of using satyrization as a tool to control the abundance of D. suzukii. By using males of D. melanogaster, we realized courtship tests, spermathecae analysis, and multiple-choice experiments to assess the occurrence and extent of pre- and post-zygotic isolation between the two species, as well as the occurrence of fitness costs in D. suzukii females due to satyrization. Our results showed that: (i) D. melanogaster males successfully courted D. suzukii females; (ii) D. melanogaster males significantly affected the total courtship time of D. suzukii males, which reduced from 22.6% to 6.4%; (iii) D. melanogaster males were able to inseminate D. suzukii and reduce their offspring, inducing a high fitness cost. Reproductive interference occurs at different steps between D. melanogaster and D. suzukii, both alone and in combination with other area-wide control approaches.
摘要：
果蝇是全球主要的农业害虫之一。因此，确定压制其人口的安全和持久工具对于减轻因其发生而造成的环境和经济损失至关重要。这里,我们探讨了使用satyrization作为控制D.suzuki丰度的工具的可能性。通过使用D.melanogaster的雄性，我们意识到了求爱测试，精子分析,和多项选择实验，以评估两个物种之间合子分离前后的发生和程度，以及由于satyrization而导致的D.suzukii女性健身费用的发生。我们的结果表明：（i）D.melanogaster雄性成功追求D.suzukii雌性；（ii）D.melanogaster雄性显着影响D.suzukii雄性的总求爱时间，从22.6%下降到6.4%；(iii)D.melanogaster雄性能够授精D.suzuki并减少其后代，诱导高健身成本。生殖干扰发生在D.melanogaster和D.suzuki之间的不同步骤，无论是单独还是与其他全区域控制方法相结合。
