SITUATION. Small-scale breeding continued in Algeria (115 ha treated) and started in northern Niger. Hopper and adult groups formed in southwest Libya. Scattered adults appeared in southeast Mauritania.
FORECAST. Small-scale breeding will occur in Mauritania, Mali, Niger and Chad, causing locust numbers to increase slightly.
