Cacao flower visitation: Low pollen deposition, low fruit set and dominance of herbivores por Vansynghel, Justine, Ocampo Ariza, Carolina, Maas, Bea, Martin, Emily A., Thomas, Evert, Hanf-Dressler, Tara, Schumacher, Nils-Christian, Ulloque-Samatelo, Carlos, Tscharntke, Teja, Steffan-Dewenter, Ingolf

“…Such factors could be, amongst others, a lack of effective pollinators, genetic incompatibility or resource limitation. Revealing efficient pollinator species and other causes of low fruit set rates is therefore key to establish location-specific management strategies and develop high yielding native cacao agroforestry systems in regions of origin of cacao.…”
