NESTING BIOLOGY OF DICRANTHIDIUM ARENARIUM (DUCKE) (HYMENOPTERA: APIDAE) IN DRY FOREST AND ATLANTIC FOREST AREAS IN STATE OF PERNAMBUCO, NORTHEAST BRAZIL
Anthidiini, Behavior, Bionomics, Parasitism, Solitary bees
Dicranthidium is a genus of solitary bees with eight described species. The species are distributed exclusively in the Neotropical region with records for Argentina, Brazil, Paraguay and Trinidad and Tobago. Although widely distributed, information about the nesting biology of the genus is restricted to two species: Dicranthidium arenarium (Ducke) and Dicranthidium luciae Urban. However, these information are related only to the material used in the construction of brood cells and immature development time. Dicranthidium arenarium is widely distributed in the Northeast of Brazil , with records for dry forest (Caatinga) and Atlantic Forest. Therefore, this study aimed to expand the knowledge about the biology of the species D. arenarium to understand patterns of seasonality, behavior, nest architecture and parasitism in two biomes of occurrence. Dicranthidium arenarium presented similar seasonality and nest architecture in both biomes, a multivoltine life cycle and the use only resin in nest construction. The information obtained increases the knowledge about the biology of the species and can contribute to the establishment of sustainable ways of preservation and conservation the species and the associatedbiomes.
