Summary
Okinawa has intensified efforts to eradicate the melon fly, a pest that damages cucurbit fruits. On August 14, helicopters released 1.2 million sterile insects across multiple areas, including Motobu Town, Kumejima, and the Kerama Islands. This aerial release method, initiated in late July, allows for broader coverage compared to ground-based methods.
