Can local products compete against imports in West Africa? Supply-and demand-side perspectives on chicken, rice, and tilapia in Accra, Ghana por Andam, Kwaw S., Ragasa, Catherine, Asante, Seth, Amewu, Sena

“…For the quality analysis, we compare consumer perceptions and demand for quality attributes of local versus imported products using data from field experiments with 1,322 consumers. Our findings suggest that among the three products, rice has the lowest prospects for import substitution, due to supply-and demand-side constraints to local competitiveness. …”

Preventive measures to limit the spread of Trioza erytreae (Del Guercio) (Hemiptera: Triozidae) in mainland Europe por Urbaneja-Bernat, Pablo, Hernández-Suárez, Estrella, Tena, Alejandro, Urbaneja, Alberto

“…Our results showed that two types of anti-insect mesh with a pore size of 0.4 × 0.77 mm2 and 0.27 × 0.77 mm2 were effective in excluding T. erytreae in two field experiments. These results have direct implications in the nursery plant production system, which should adopt meshes with pore sizes small enough to guarantee the exclusion of T. erytreae. …”
