Hot off the press!  Dr. Farah Carrasco Ruedo (PhD 2018, UF) studied this question for her dissertation research in a recently converted forest destined for palm production in the Amazon of north-central Peru.  Her results were just published in Ecology and Evolution and can be found here.  These riparian forest strips add important habitat diversity to the agricultural lands and do help to maintain bat taxonomic and function diversity, although we caution that their value depends on maintenance of larger forests in the area.
