Searching for a Manageable Pollinator for Acerola Orchards: The Solitary Oil-Collecting Bee Centris analis (Hymenoptera: Apidae: Centridini)
TLDR
This work proposes the commercial use of Centris bees as orchard pollinators for the first time, and analyzes trap-nest acceptance, brood-cell construction, and larval diet in Acerola orchards to develop protocols for rearing and management.
Do euglossine males (Apidae, Euglossini) leave tropical rainforest to collect fragrances in sugarcane monocultures?
TLDR
In an isolated fragment of Atlantic Rainforest in Pernambuco, NE Brazil, surrounded by sugarcane monocultures, it was examined if euglossine males leave closed rainforest to collect fragrances, demonstrating different relations of the Euglossini species to the closed forest.
Stamen movements in flowers ofOpuntia (Cactaceae) favour oligolectic pollinators
TLDR
Through their stamen movements, Opuntia flowers hide most of their pollen from flower visitors but favour effectively pollinating, oligolectic bees.
Caladium bicolor (Araceae) and Cyclocephala celata (Coleoptera, Dynastinae): a well-established pollination system in the Northern Atlantic rainforest of Pernambuco, Brazil.
TLDR
Findings of previous studies in the Amazon basin of Surinam indicated that Cyclocephala rustica is a likely pollinator of C. bicolor, which leads to the assumption that locally abundant Cyclocephalini species are involved in the pollination of this species.
Limited Fruit Production in Hancornia speciosa (Apocynaceae) and Pollination by Nocturnal and Diurnal Insects 1
TLDR
Investigation of the breeding and pollination systems of H. speciosa, as well as the Brazilianfruit industry, found fruit production of hand cross-pollinated flowers increased by 90 percent when compared to natural pollination, suggesting pollinator limitation of the plant.
The Key Role of 4-methyl-5-vinylthiazole in the Attraction of Scarab Beetle Pollinators: a Unique Olfactory Floral Signal Shared by Annonaceae and Araceae
TLDR
4-Methyl-5-vinylthiazole, a nitrogen and sulphur-containing heterocyclic compound previously unreported in flowers, was found as a prominent constituent in all studied species and it is hypothesize that the presence of this compound in unrelated lineages of angiosperms is either linked to selective expression of a plesiomorphic biosynthetic pathway or to parallel evolution.
The cowl does not make the monk: scarab beetle pollination of the Neotropical aroid Taccarum ulei (Araceae: Spathicarpeae)
TLDR
Comparative multivariate analysis of the floral traits of T. ulei points to a beetle-pollinated aroid, although some of the observed traits of the species are not common to other taxa sharing this pollination strategy, which might be explained by the evolutionary history of the tribe Spathicarpeae and potential pollinator shifts.
Pollination of Philodendron acutatum (Araceae) in the Atlantic Forest of Northeastern Brazil: A Single Scarab Beetle Species Guarantees High Fruit Set
TLDR
A study of the species’ breeding system and associations with flower‐visiting insects, along with an analysis of its floral scent composition, suggests a local reproductive dependence of the plant to this scarab beetle species.
Seasonality of Fruit-Feeding Butterflies (Lepidoptera, Nymphalidae) in a Brazilian Semiarid Area
TLDR
Both abundance and richness were affected by season in a manner that the rainy period had significantly more individuals and species than the dry period, and a strong positive correlation was found between butterfly abundance and precipitation of the sampled year.
Comparative bioacoustical studies on flight and buzzing of neotropical bees
TLDR
A new field method using a commercially available portable system able to record the sound of bees during flight and buzzing at flowers is presented and computer linguistical algorithms are described to analyse the frequency of the recorded sound sequences.
