The genus Cyclocephala Dejean (Coleoptera: Scarabaeidae: Dynastinae) in Brazil: diversity and spatio-temporal distribution

(3S,6E)-nerolidol-mediated rendezvous of Cyclocephala paraguayensis beetles in bottle gourd flowers

“…Thus, it is unlikely that the relationship of C. paraguayensis with these flowers is specific. Besides, floral preferences by Cyclocephala species may reflect in gregarious distribution; once C. paraguayensis beetles are widely distributed in Brazil [22], we surmise they exploit broader odor components than other Cyclocephala species with mutualistic PLOS ONE floral interaction. Possibly, C. paraguayensis represents a case of beetle acquiring preference for certain floral odors by its feeding habit during the larval stage; and/or it approaches these flowers when few or no cantharophilous species are in anthesis [15].…”

“…Piracicaba comprises the biome Atlantic Rain Forest, which has been observed to harbor small and scattered populations of C. paraguayensis. Conversely, Cassilândia is located in the biome Cerrado, which appears to sustain a higher population of this species [22].…”

Seasonality and distribution of Coleoptera families (Arthropoda, Insecta) in the Cerrado of Central Brazil

“…Coleoptera studies have used different sampling methods, for example light trap, pheromone, fermented bait, malaise trap, flight interception traps and pitfalls (Ganho and Marinoni, 2003;Silva et al, 2017a;Gonçalves et al, 2020;Puker et al, 2020;Evangelista et al, 2021;Oliveira et al, 2021), and more than one method is often used in a complementary way. However, since many Coleoptera are phototropic, light traps have been one of the main collection methods for studies aimed at evaluating adult diversity (Miyazaki and Dutra, 1995;Freitas et al, 2002;Jocque et al, 2016;Gonçalves et al, 2020). Thus, the objective of this study was to evaluate the seasonality and distribution of Coleoptera families in an area of the Cerrado biome in the Federal District (DF) of Brazil, using light trap.…”
