In Southern Brazil the great diversity of bees is due to the richness of ecosystems in the region and when studies attribute the processes for identification of the floral resources used by bees we can get important steps for the elaboration of management and conservation plans of the species involved. Based on this setting and considering that the study area is a "várzea" (swamp) with a large concentration of flowers of Ludwigia sericea and Ludwigia peruviana, important sources of resources for bees, the aim of this study was to find out about the floral visitor bees and through palynological studies and interaction networks, understand the role of these plants as providers of  pollengrains to bees and how the bees interact with them and other plants, also found in this habitat. Ludwigia sericea, Ludwigia peruviana and the other plant species are presented as generalist in the interactions with the bee species, and the same occurs for most of the bee species in relation to these plants. Generalist bee species (Bombus pauloensis, Apis mellifera, Augochlora amphitrite and Melissoptila paraguayensis) tend to be more abundant and more resistant to disturbances than the specialist species. It was the first time that Plebeia emerina, Centris varia, Mourella caerulea and Augochlorella ephyra were recorded on the Ludwigia flowers in Brazil. Based on the results presented in this study, these plants are important for maintaining the bee community in the region of the Atlantic Forest in Southern Brazil, because they provide resources (nectar and pollen) to bee species that only occur in this region.

Rio Grande do Sul (RS) is the southernmost state in Brazil and includes areas within the Pampa and Atlantic Forest biomes. The semiaquatic bugs (Hemiptera, Heteroptera, Gerromorpha) from RS are poorly known, with only 14 previously recorded species. We carried out two expeditions in this state, in 2002 and 2019, across 19 municipalities. Here, we provide new records for 19 species, of which 13 are recorded for the first time from the state, five have their distributions expanded, and one is recorded again from a same locality previously reported in the literature. Furthermore, 13 species were collected for the first time in the Pampa biome and one in the Atlantic Forest.

The present paper transfers Mutilla pumila Burmeister, 1854 and Mutilla pergrata Cresson, 1902 to the genus Pseudomethoca Ashmead, and a lectotype is designated for Mutilla pumila. The male of this species, previously known only from the female sex, is described and the female is redescribed and illustrated for the first time. Sex association was based on laboratory mating trials. Field observations in a montane Atlantic forest site in southern Brazil provided us behavioural notes on attempts of parasitism in nests of the halictine bee Dialictus seabrai (Moure, 1956).

Abstract In the present study, Litomosoides silvai parasitizing Akodon montensis in the southern region of Brazil is reported for the first time. New morphological information is provided for some structures of this nematode species, such as a flattened cephalic extremity, presence of two dorsal cephalic papillae, female tail with a constriction at its tip, “s” shaped vagina, spicules characteristic of the carinii species group and microfilaria tail constricted at the tip. This nematode was found parasitizing the thoracic cavity with a prevalence of 10% (2/20), mean intensity of 4 (6/2), mean abundance of 0.4 (8/20) and range of infection of 2-6 specimens per host, in southern Brazil. This occurrence of L. silvai in A. montensis is a new geographical record for southern Brazil, in the Upper Paraná Atlantic Forest ecoregion of the northwestern region of Rio Grande do Sul, which is part of the Atlantic Forest biome.

Aiming to verify the relationships between native bees and floral resources in an urban area, their interactions were observed in Joinville, state of Santa Catarina, southern Brazil. Observations were established, lasting 8 hours daily, during different periods from 2009 to 2015. Bees and plants, after preparation, were identified and registered in a database. We sampled 3,073 bees, all of which 1042 were wild native species. The collected bees are included in 34 species and 44 morphospecies (Halictinae-35, Megachilinae-17, Apinae non corbiculate-15, Apinae corbiculate- 10, Andreninae-1). With the exception of Apis mellifera, the most abundant bee taxa sampled were Trigona spinipes (330 individuals), Xylocopa brasilianorum (92) and Pseudaugochlora graminea (92). Euglossini females and species poorly sampled in inventories such as Leiopodus lacertinus, Thygater (Thygater) armandoi, Anthodioctes megachiloides and Coelioxys aculeaticeps were captured. The bees were sampled over 83 botanical species of 38 families. The most visited botanical families were Lamiaceae and Asteraceae. The richness of the studied area is lower than those of other nearby compared places, indicating probably a decrease of the apifauna. The found diversity previews the place as a possible refuge.

Lynchiatilla parana Cambra in Bergamaschi et al., sp. nov. (female and male) from Brazil and the male of Lynchiatilla leguera Casal, 1963 are newly described and illustrated. Lynchiatilla silvai Casal, 1963 is reported for the first time for the state of Paraná, southern Brazil. A key to the males for those species where they are known is given. Specimens of L. parana sp. nov. were observed and collected during 204 hours of fieldwork in a montane Atlantic Forest area, providing behavioral data and implicating the halictine bee Paroxystoglossa spiloptera Moure, 1960 as its probable host. Adult wasps were captured and kept in individual containers for sex-association mating trials in the laboratory. Color and size variation in a population of L. leguera from Jujuy, northern Argentina, are discussed and illustrated.

Bromeliad-associated mosquitoes (Diptera: Culicidae) in Atlantic Forest in Florianópolis, Santa Catarina, southern Brazil, were studied, examining plants of Vriesea philippocoburgi Wawra and Aechmea lindenii (E. Morren) Baker var. lindenii at secondary Atlantic rain forest, and A. lindenii and Vriesea friburgensis Mez var. paludosa (L. B. Smith) at "restinga" per month, during 12 months. No immature forms of mosquitoes were collected from A. lindenii in the secondary forest. Collections obtained 368 immature mosquitoes, none of them from A. lindenii from rain forest. Culex (Microculex) spp. constituted 79.8% of the total, Wyeomyia (Phoniomyia) spp. 17.93%, and Anopheles (Kerteszia) cruzii (Dyar & Knab, 1908) only 1.36%. The study shows the great predominance of species of medical importance not yet proved, and the small number of immature stages of anopheline mosquitoes. The rainfall, but not the mean temperatures, significantly influenced the quantity of mosquitoes from V. philippocoburgi. Significant differences between the quantities of immature forms of all the bromeliad species were found, and the shape of the plants could be important to the abundance of mosquitoes. All six species of Cx. (Microculex) found are recorded for the first time in the State of Santa Catarina, and all six species of Wyeomyia (Phoniomyia) are recorded for the first time in bromeliads in this state.

Abstract. Background: Little is known about the role of resilience in the likelihood of suicidal ideation (SI) over time. Aims: We examined the association between resilience and SI in a young-adult cohort over 4 years. Our objectives were to determine whether resilience was associated with SI at follow-up or, conversely, whether SI was associated with lowered resilience at follow-up. Method: Participants were selected from the Personality and Total Health (PATH) Through Life Project from Canberra and Queanbeyan, Australia, aged 28–32 years at the first time point and 32–36 at the second. Multinomial, linear, and binary regression analyses explored the association between resilience and SI over two time points. Models were adjusted for suicidality risk factors. Results: While unadjusted analyses identified associations between resilience and SI, these effects were fully explained by the inclusion of other suicidality risk factors. Conclusion: Despite strong cross-sectional associations, resilience and SI appear to be unrelated in a longitudinal context, once risk/resilience factors are controlled for. As independent indicators of psychological well-being, suicidality and resilience are essential if current status is to be captured. However, the addition of other factors (e.g., support, mastery) makes this association tenuous. Consequently, resilience per se may not be protective of SI.
