Abstract

The Desert Locust (Schistoseca gregaria - SGR1): The SGR situation remained extremely serious in the Horn of Africa in the central outbreak region (COR) where hoppers, adults and swarms continued developing in Kenya, Ethiopia and Somalia during March. In South Sudan, several mature swarms from Kenya appeared in the southeast during the 2nd dekad of March and flew later eastward towards southwestern Ethiopia on March 23rd. In Sudan, vegetation continued drying up on the Red Sea coast and only a few scattered adult locusts were present on the south coast. In Eritrea, ground control operations continued against groups of late instar hoppers and immature adults on the southern Red Sea coastal areas. In Djibouti, immature adult locusts and hoppers were detected in Kalaf in Tadjoura northwest of the country. In Yemen, scattered immature and mature adults were detected on the northern Red Sea coast in Tihama and hopper bands continue appearing and immature adults are starting to form groups on southern coast near Aden. In Saudi Arabia, limited control operations were carried out against a few mature adult groups in the interior in the north. In Oman, control operations continued against hopper groups in northern interior and new groups that just hatched on north coast. Close to 98,000 ha were controlled in COR during March. In the eastern outbreak region (EOR), hatching and late instar hopper band formations continued in southwestern parts of Iran and hopper groups continued forming in Baluchistan in western Pakistan and control operations treated more than 67,330 ha against hoppers and immature adults. The western outbreak region (WOR) remained calm during this month.
