Summary
The high commercial value of "cupuaçu" Theobroma grandiflorum (Willd. ex Spreng.) Schum. (Sterculiaceae), and its native occurrence in Amazonian led us to make some observations on the insects which are eating the leaves and flowers of this plant. Some observations about its pollination are given, and very probably Ptilotrigona lurida (Smith) is responsible by it. The results are presented in Tables — 1 and 2, and some aspects of the attack of flowers by bees is shown in Fig. 1.
