    Abstract In co-flowering plant communities, pollinator movement can lead to the transfer of heterospecific pollen among species. This can affect the reproductive success of individuals, either by preventing conspecific pollen from reaching the stigma or by allelopathy, but little is known about this process in tropical areas. To analyze heterospecific pollen transfer and deposition, we investigated attributes related to pollinator attraction, such as corolla size, number of flowers per individual, floral arrangement, floral asymmetry, and distance from one flowering individual to another in a Central Amazon forest. The study was carried out in riparian plots of the Adolpho Ducke Forest Reserve during the rainy season. Stigmas and anthers were removed from all individual understory plants found in bloom in permanent plots. Slides were mounted with glycerinated gelatin, and all conspecific and heterospecific pollen grains were identified and counted. We then used a generalized linear mixed model framework to determine how the measured variables were related to the proportion of heterospecific pollen deposition (HPD) on stigmas. We found that the mean proportion of HPD in individuals was 4.7%, and 60% of individuals had no heterospecific pollen; from the 14 species studied, two had no heterospecific pollen. Species with wider flowers received less HPD, while species with more flowers per individual and with solitary flowers received more heterospecific pollen. Despite the significant variation in floral types in the Adolpho Ducke Reserve, there was a low percentage of heterospecific pollen deposition, probably due to specialized plant-pollinator interactions.

    Abstract Biotic pollination and pest control are two critical insect-mediated ecosystem services that support crop production. Although management of both services is usually treated separately, the new paradigm of Integrated Pest and Pollinator Management (IPPM) suggests synergetic benefits by considering them together. We reviewed the management practices in two major tropical perennial crops: cocoa and coffee, to assess IPPM applications under the tropics. We found potential synergies and antagonisms among crop pest and pollination management, however, very few studies considered these interactions. Interestingly, we also found management practices focusing mainly on a single service mediated by insects although species can show multiple ecological functions as pests, natural enemies, or pollinators. The tropics represent a promising area for the implementation of IPPM and future research should address this concept to move towards a more sustainable agriculture.

    Abstract Habitat loss and fragmentation are drivers of biodiversity loss, such as Euglossini bees in continental regions. Knowledge about these effects on this group of pollinators in coastal regions is still incipient and needs to be further investigated. This study aimed to evaluate the effects of landscape structure on the abundance, richness, diversity and species composition of Euglossini bees on the coast of the Brazilian Amazon. We mapped the surrounding landscape around 48 sampling points in the east of the island of Marajó, Pará, Brazil where we collected bees using chemical baits. We used Generalized Linear Models (GLMs) to evaluate the effects of landscape structure (composition and configuration) on the abundance, richness, diversity and composition of Euglossini bees. We collected a total of 1017 males belonging to four genera and 22 species. Forest cover (%) and landscape heterogeneity were the best predictors of the bee community. Increased forest cover positively affected the abundance, richness and diversity of bees at a local scale. On the other hand, abundance, richness and diversity decreased with increasing landscape heterogeneity, also at a local scale. The hypothesis that the amount of habitat favors Euglossini communities was corroborated by our results. Based on our conclusions, landscapes with greater forest cover can effectively contribute to the conservation of these bees and their pollination services along the Amazon coast.

    Abstract We report the first record of the neotropical bee subgenus Hylaeus (Gongyloprosopis) Snelling, 1982 (Colletidae) for Brazil. Additionally, an overview of the current geographic records for the three known species of the subgenus is presented. We expand the distribution of Hylaeus (Gongyloprosopis) orbicus (Vachal, 1910), the male is illustrated, and the first floral association with Vismia japurensis Reichardt (Hypericaeae) is reported for this species.

    Abstract Despite the huge diversity of Doryctinae, with about 3,000 species estimated, the subfamily also has about 30% of its approximately 205 genera as monotypic. Most of these monotypic genera are known from a few specimens used to describe its species and then remain without further records. Here we were able to enlarge the distribution knowledge of a monotypic genera making the first record of Parsteres pilosus Gadelha, Nunes & Oliveira, 2016, to the Atlantic Forest biome at Salvador, Bahia, Brazil.
