| Sumario: | This study aimed to assess the efficiency of <em>Centris aenea</em> Lepeletier as pollinator of <em>Malpighia emarginata </em>DC. The pollination efficiency was determined according to three criteria: 1) the pollen deposition rate of <em>M. emarginata</em> and other plant species on the thorax ventral region of females, 2) the rate of <em>M. emarginata</em> fruit set after a single visit, and 3) the pollen deposition rate on the stigma after one single visit. 59% of the pollen grains deposited on the ventral region of <em>C. aenea</em> came from flowers of <em>M. emarginata. </em>The fruit set after a single visit by <em>C. aenea</em> (21%) was much higher than that reported previously for <em>Centris tarsata </em>Smith. We argue that pollination efficiency of <em>C. aenea</em> can be related to its body size, since that females of <em>C. aenea</em> can carry larger amounts of pollen grains of <em>M. emarginata</em> than <em>C. tarsata</em>, as well females of <em>C. aenea </em>are able to touch a larger stigma area, resulting in higher fruit sets after a single visit. Our study suggests that only one visit by <em>C. aenea</em> ensures fruit set in <em>M. emarginata.</em> |
