Resultados de pesquisa demonstraram que em Ouro Preto e Ariquemes-Rondonia, as maiores producoes de MS sao obtidas com corte a 10 e 20cm e 25 e 30cm acima do solo, respectivamente, enquanto que em Presidente Medice-RO a altura de corte nao afetou a producao de MS, contudo, visando asssegurar maior persistencia da capineira, recomenda-se corte acima de 10cm. Cortes e baixa altura (5 e 10cm) implicam na reducao dos stands e em incremento da infestacao de invasoras. Nos tres locais, a altura de corte nao influenciou os teores de PB da forragem. |

Abstract: Understanding the functional roles of different pollinator species is crucial to the development of sustainable farming practices in pollinator-dependent crops. However, this can be challenging for crop plants in tropical regions with hyper-diverse pollinator communities. Here, we assess pollen loads of different insect visitors to inflorescences of açaí palm (Euterpe oleracea), the most important native crop in the Amazon estuary region. Flower-visiting insects were collected from pistillate (female) inflorescences at eight sites, including four managed floodplain forests and four plantations. Pollinator Importance Value Index (PIVI) and Relative Importance (RI) scores were calculated for common visitor taxa (higher or equal 10 individuals) using sum visit frequencies and median pollen loads. Pollen load analyses revealed that over seventy insect taxa, including bees, flies, beetles, wasps and ants, were effective vectors of E. oleracea pollen. Native bees, including both solitary and eusocial taxa, were the most efficient pollen vectors, with median pollen loads at least eight times higher than those of the next best insect group (flies). Insect pollen loads were at their highest between 0800 and 1300 hours, and four insect taxa had RI scores > 0.05, including two meliponine bees belonging to the Trigona genus (Trigona branneri Cockerell and Trigona pallens Fabricius) and two halictid bee genera (Augochloropsis and Dialictus). Our results suggest that native bees play an important role in açaí pollination and should be the primary focus of pollinator management in açaí production systems.
