A novel butenolide insecticide—flupyradifurone (Sivanto SL 200)—was evaluated for efficacy against cassava-colonizing Bemisia tabaci whitefly under laboratory, screenhouse and field conditions. LC50 values from leaf disc spray assays were comparable for both flupyradifurone (12.7 g a.i/100 L) and imidacloprid (12.6 g a.i/100 L). Both insecticides caused high levels of adult whitefly mortality in leaf disc and leaf dip assays when compared to untreated controls.

An online survey was co-designed in collaboration with CGIAR Germplasm Health Units (GHUs) leaders and social scientists of the Plant Health Initiative (PHI), with the objective to identify and map the key knowledge and capacity gaps on lab/field detection, characterization, and surveillance of P&D of local and regional NPPOs in targeted countries. The questionnaire consisted of 43 open-ended, single and multiple-choice questions.

Plants live under different biotic and abiotic stress conditions, and, to cope with the adversity and severity, plants have well-developed resistance mechanisms. The mechanism starts with perception of the stimuli followed by molecular, biochemical, and physiological adaptive measures. The family of LRR-RLKs (leucine-rich repeat receptor-like kinases) is one such group that perceives biotic and abiotic stimuli and also plays important roles in different biological processes of development.

Bactrocera dorsalis and several Africa-native Ceratitis species are serious constraints to fruit
production in sub-Saharan Africa. A long-term trapping and fruit collection study was conducted
(2011–2016) in two contrasting agro-ecological zones (AEZs) of Cameroon to determine fruit fly
species composition, seasonality, attraction to various lures and baits, and fruit infestation levels.
Ten tephritid species from genera Bactrocera, Ceratitis, Dacus, and Perilampsis were captured in traps.

The adaptability and stability of 37 faba bean (Vicia faba L.) accessions with different levels of tolerance to metribuzin or imazethapyr was assessed across 12 season–location–herbicide experiments. Significant Genotype x environment (GE) interaction was found for the days to flowering (DFLR), plant height (PLHT) and grain yield (GY). Performance and stability of the accessions regarding PLHT and GY were assessed using four different stability parameters: cultivar superiority, static stability, Wricke’s eco-valence and Finlay and Wilkinson’s regression model.

Capacity development is an important part of the Accelerating Impacts of CGIAR Climate Research for Africa (AICCRA) strategy to make climate services and climate-smart agriculture more accessible to millions of smallholder farmers across Africa.

Ethiopia is the world’s second largest producer of faba bean (Vicia faba L.), and the crop has largest share of area and production of all pulses grown in Ethiopia. Faba bean is valued for its source of protein, income, and animal feedstock, and an important rotational crop. However, its current productivity is very low due to an emerging faba bean gall (FBG) disease and other biotic constraints. Initially, FBG disease-causing pathogen remained unconfirmed, but it was assumed to be caused by Olpidium sp.

The aim of the dissertation was to undertake phenotypic and genetic characterization and design community-based breeding programs for two indigenous goat populations in Ethiopia, namely Arab and Oromo. The dissertation was based on five manuscripts. Papers I, II, IV and V were based on data generated from production system, morphological characterization and ranking experiments. Paper III was based on whole genome data generated from three indigenous goat populations (Arab, Fellata and Oromo).

This paper analyses the ways in which CGIAR Centers use digital sequence information (DSI) in their efforts to conserve and sustainably utilize the world’s most important crop and livestock genetic diversity.

High temperature and water deficit are among the major limitations reducing lentil (Lens culinaris Medik.) yield in many growing regions. In addition, increasing atmospheric vapor pressure deficit (VPD) due to global warming causes a severe challenge by influencing the water balance of the plants, thus also affecting growth and yield.

The objective of this study is to map community solutions to deal with climate variability and how information is mobilized into or interfaces with the next layer of government interventions that brings new perspectives in understanding how local solutions can be better mobilized into external solutions to climate change adaptation through horizontal and vertical integration processes, with a focus on living community-based water tenure in rural Zambia.
