Emergency transboundary outbreak pest (ETOP) situation bulletin for March with a forecast through mid-may 2022.
The Desert Locust (Schistoseca gregaria - SGR1): The desert locust (SGR) situation remained generally calm in the Central Outbreak Region (COR) during this month, and only a few immature swarms were treated on 400 ha in southern Ethiopia. A few scattered adults were also detected in northern and southern coastal areas in Sudan and southern coast of Egypt, but control operations were not necessitated. Isolated adults were reported in a few places on the Gulf of Aden coast in southern Yemen. No locusts were reported elsewhere in the region. The Western (WOR) the Eastern (EOR) Outbreak Regions remained calm. Forecast: Ecological conditions continue drying up in the COR causing locust numbers to further decline. Only low numbers of adults may appear in spring breeding areas in the interior of Saudi Arabia and Yemen, but poor rains are expected to limit breeding during the forecast period. In WOR, limited breeding may occur in Morocco and Algeria should there be more rain in the coming months. In EOR, isolated adults are likely to appear, but any breeding will be on a very limited scale due to poor rainfall in the forecast Red (Nomadic) Locust (Nomadacris septemfasciata) (NSE): NSE situation remained calm in the primary outbreak areas during March. Fledging was expected to have occurred in Lake Chilwa/Lake Chiuta plains and Mpatsanjoka Dambo in Malawi; Ikuu-Katavi, Malagarasi, Rukwa plains and Bahi Valley in Tanzania; Kafue Flats in Zambia; and Buz Gorongosa and Dimba plains in Mozambique. African Migratory Locust (Locusta migratoria migratorioides) (AML): Isolated populations of AML persisted in Simalaha Plains in Zambia. Significant outbreaks were not reported in Zimbabwe during this month. Malagasy locust (Locust migratoria capito) (LMC): In Madagascar, aerial and ground survey and control operations continued against hopper groups and bands and immature and mature adults. Tree Locusts, Anacridium spp. (ASP): ASP activities were not reported during this month. Central American Locust, Schistocerca piceiferons (CAL): No update was received on CAL South American Locust, Schistocerca cancellata (SAL): No update was received at the time this bulletin was compiled. Italian (CIT), Moroccan (DMA), and Asian Migratory Locusts (LMI): DMA, CIT and LMI activities remined calm in the CCA regions. Fall Armyworm (Spodoptera frugiperda, J. E. Smith) (FAW): FAW infestations persisted in all maize growing regions in Zambia; in Blantyre Agriculture Development Division in Malawi; in Masvingo, Mazowe, Gokwe, Lupane and Hwange areas in Zimbabwe. In Kenya, FAW was reported attacking maize in Narok, Bomet, Kakamega, Bungoma and Busia Counties. No reports were received elsewhere during this time. African Armyworm (Spodoptera exempta) (AAW): AAW outbreaks were reported in Tanzania, Malawi, and Kenya where affected farmers carried out control operations with the support from their respective MoAs. Quelea species (QSP): QSP outbreaks were reported in Ethiopia, Tanzania, and Zimbabwe where the pest was causing damage to wheat, rice, and/or sorghum. Active surveillance, monitoring and timely preventive and curative control as well as timely sharing of information on ETPs remain critical to abate the threats ETOPs pose to food security and livelihoods of vulnerable communities. USAID/BHA/TPQ regularly monitors ETOPs in close collaboration with its global network of PPDs/DPVs, regional and international pest monitoring and control entities, FAO, CLCPRO, CRC, DLCO-EA, and IRLCO-CSA, and research centers, academia, private sector, NGOs and others and issues monthly analytical ETOP Bulletins to stakeholders (refer to list of acronyms on the last pages).
