I am presently involved in a project to study possible impacts of microbial pesticides on non-target organisms in Brazil. We are interested on evaluating possible effects of those pesticides on honey-bees. For that evaluation, we are trying to maintain approximately 30 bees in captivity (box of ca. 12x12x5 cm) for at least 25 days. We are following methodology described in a few papers we have seen. However, we are unable to maintain those insects alive in those conditions for more than 2-3 days. Could anyone help us with that problem. Thank you very much. [log in to unmask] [B [B [B [B [B
