Abstract: O presente ensaio, realizado com a var. bourbon de Coffea arabica, além de dar informações sôbre a produção dos cafeeiros protegidos dos insetos polinizadores, permitiu também averiguar o comportamento de várias espécies de abelhas e obter outras informações correlatas. Constatou-se, assim, que o néctar da flor é ainda abundante mesmo 24 horas após a antese e que o teor de açúcar do néctar é elevado, da ordem de 38%, em média. Apis mellifera foi a espécie mais freqüentemente encontrada coletando o néctar e o p… Show more

“…An additional hypothesis is that this optimum range should directly influence the relative abundance of these species in a given area. Nogueira-Neto et al (1959), studying insect pollinators activity on coffee plantations, observed that three species of Plebeia did leave their hives in temperatures around 17-18 o C. Käpylä (1974) assigned that flight activity depends on insects' body size. Bigger species fly on temperatures and light intensities lower than smaller ones, thus demonstrating a better capacity to absorb heat.…”

“…The potential of P. remota as a pollinator of commercial crops is still unknown, though Plebeia spp. are known to intensively visit Coffea arabica L. (nOgueira-netO et al, 1959) and Syzygium jambos (L.) Alston (knOll & imperatriz-FOnseca, 1993). Studies made of pollen grains in pollen and honey pots of P. remota have shown a prevalence of Arecaceae and Moraceae.…”

“…by evolving resistance to the effects of nectar compounds. To gain a better understanding of the potential effects of caffeinated nectar on plant-pollinator interactions in the tropics, we studied the Brazilian stingless bee Plebeia droryana, which was found to be the most common native bee visitor of Coffea and Citrus in the state of São Paulo, Brazil (Nogueira-Neto et al, 1959;Imperatriz-Fonseca et al, 1989).…”
