Applying Satyrization to Insect Pest Control: The Case of the Spotted Wing Drosophila, Matsumura.

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 . By using males of , 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 females due to satyrization. Our results showed that: (i) males successfully courted females; (ii) males significantly affected the total courtship time of males, which reduced from 22.6% to 6.4%; (iii) males were able to inseminate and reduce their offspring, inducing a high fitness cost. Reproductive interference occurs at different steps between and , both alone and in combination with other area-wide control approaches.
