Abstract
Abstract The oil palm, Elaeis guineensis Jacquin, is an allogamous and monoecious plant that is mainly pollinated by insects such as Mystrops costaricensis Gillogly (Coleoptera: Nitidulidae) and Elaeidobius kamerunicus Faust (Coleoptera: Curculionidae). To determine the relationship between inflorescences and pollinators as well as the relationship between pollinators and bunch components, 858 palms, divided equally between two plots planting with cultivars tenera and dura of E. guineensis, were monitored every 2 weeks over 1 yr. Male inflorescences (MIs) and female inflorescences (FIs) at anthesis, and pollinators collected from the inflorescences, were recorded at each sampling. Bunch components and the amount of rainfall during the study period also were recorded. Data were analyzed using Spearman correlations and linear regression. Significant positive correlations of the total number of MIs with the total number of pollinators were found in both cultivars (ρ = 0.72, P < 0.0001, n = 24 in cultivar te...
