摘要

Epanthidium tigrinum is a solitary Neotropical bee with great potential for agricultural pollination, especially of crops such as guava (Psidium guajava L.), acerola (Malpighia emarginata DC.), cashew (Anacardium occidentale L.), and cowpea (Vigna unguiculata (L.) Walp.). The availability of resources such as pollen, nectar, and resin limits the nest provisioning activity, but little is known about the plant species it use. This study investigated the flora used by nesting E. tigrinum in an urban area in northeastern Brazil over two-year period. The bee is multivoltine, alternating between periods of higher and lower nesting activity, depending on the quantity and availability of resources.Its feeding habit varies from polylectic foraging during periods of limited floral resources to the frequent use of certain plant species when these are highly abundant. Up to 25 types of pollen were identified in the nests, with seasonal variation. Bipartite networks revealed patterns of connectivity, nesting, and modularity and involved interactions between Epanthidium tigrinum and 25 pollen types from 15 botanical families, primarily Fabaceae, Bignoniaceae, Anacardiaceae, Malpighiaceae, and Euphorbiaceae. The study also identified essential plant species for nesting, such as Leucaena leucocephala and Ludwigia octovalvis, as well as cultivated species like cashew (Anacardium occidentale) and acerola (Malpighia emarginata) that may benefit from pollination. This is relevant for the conservation and management of E. tigrinum and other economically important Megachilidae species.
