Abstract

Emergency transboundary outbreak pest (ETOP) situation bulletin for July with a forecast through mid-September 2022.

Abstract

The Desert Locust (Schistoseca gregaria - SGR1): The desert locust (SGR) situation remained calm during July in the Central Out Outbreak Region (COR). Only a few solitary adults and hoppers were detected in a few places in summer breeding areas in Sudan. No locusts were detected during survey operations in Eritrea, Ethiopia, Oman, or Yemen. No locusts were detected in summer breeding areas in the Western outbreak region (WOR). No locusts were reported in the Eastern outbreak region (EOR). Forecast: In COR, small-scale breeding is likely in summer breeding areas in Sudan and Yemen and perhaps Oman. In WOR, small-scale breeding is likely in summer breeding areas in Mauritania, Mali, Niger, and Chad in areas of seasonal precipitation, but significant development is not expected during the forecast period. In EOR, small-scale breeding may commence in Iran where substantial amount of rainfall was reported. The Indo-Pakistan borders may also experience limited presence of SGR at the foothills of the monsoon rains, but significant developments are not expected. Red (Nomadic) Locust (Nomadacris septemfasciata) (NSE): Significant NSE populations were detected in Ikuu plains in Tanzania and 2,500 ha were targeted for control operations. The pest remained a concern in Chilwa/Lake Chiuta plains, Mpatsanjoka Dambo in Malawi; Buzi Gorongosa and Dimba plains in Mozambique and Kafue Flats in Zambia. African Migratory Locust (Locusta migratoria migratorioides) (LMI - AML): LMI presence was not reported. Malagasy locust (Locust migratoria capito) (LMC): LMC situation has wound down as the cold weather and dry conditions caused locusts to disperse and disappear. Tree Locusts, Anacridium spp. (ASP): ASP activities were not reported during this month. Central American Locust, Schistocerca piceiferons (CAL): CAL remains calm in Central America and only a few solitary hoppers and transient populations were detected in Guatemala. South American Locust, Schistocerca cancellata (SAL): No update was received at the time this bulletin was compiled and significant development is not expected. Italian (CIT), Moroccan (DMA), and Asian Migratory Locusts (LMI): DMA activities have come to an end in the southern region of the CCA but continued in Caucasus and northern CA countries. CIT and LMI continued hatching, hopper formations and fledging in different countries. Fall Armyworm (Spodoptera frugiperda, J. E. Smith) (FAW): FAW infestations continued affecting maize and other crops in Ethiopia, Kenya, Malawi, and Zimbabwe. African Armyworm (Spodoptera exempta) (AAW): AAW outbreaks were reported Eritrea, Ethiopia, and Kenya where control operations were carried out by the affected farmers in collaboration with the MoAs. Quelea species (QSP): QSP outbreaks were reported in Kenya, Tanzania, and Zimbabwe, the pest was causing damage to millet, rice, sorghum and/or wheat. 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 National MoA PPDs/DPVs/PHSs, 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 (please refer to list of acronyms on the last pages).
