The results showed that the current epidemiological status is critical in the coastal region, with 80% of the population in risk areas and 30% in epidemiological outbreak areas, and suggest that the area covered by the vector distribution in Brazil will decrease in future projections in the north, but will spread to the south.

The results showed that males with more opaque wings and larger red spots were more likely to win contests, and suggested that there is a variation in the assessment strategy adopted by males.

The results suggest that UV, together with pigmentation, plays a role during mate recognition in males and females, and it seems that fluorescence signals and UV reflectance can also be part of communication in odonates.
Resource defense polygyny by Hetaerina rosea Selys (Odonata: Calopterygidae): influence of age and wing pigmentation.
The authors' results showed that males with larger pigmented areas won more contests, independently of body size, and whether body size and wing pigmentation are selectable traits in male-male competition, and if age affects male territorial behavior.
Ants Visiting the Post-Floral Secretions of Pericarpial Nectaries in Palicourea rigida (Rubiaceae) Provide Protection Against Leaf Herbivores But Not Against Seed Parasites

After pollination, the floral nectaries of P. rigida act as EFNs, attracting visiting ants, and the ant-plant mutualism is context-dependent based on the type of herbivore and the plant tissue consumed.
Behavior of the Amazonian damselfly Chalcopteryx scintillans McLachlan (Zygoptera: Polythoridae) and comments on its morphological distinction from C. rutilans (Rambur)
This work describes the territorial and courtship behavior of Chalcopteryx scintillans McLachlan, an Amazonian damselfly with shiny copper-colored hind wings, and presents behavioral notes on reproductive and oviposition behavior.

The results show that the number of species with exophytic or epiphytic behaviour was strongly related to riparian forest loss, highlighting the importance of using behavioural traits as a bioindicator tool for the assessment of anthropogenic impacts on tropical forest.
First observation of alternative food usage (extrafloral nectar) by the assassin bug Atopozelus opsimus (Hemiptera, Reduviidae)
The results suggest that the diet of all instars and adults consist mainly of extrafloral nectar, in detriment of captured prey ingestion, and there was no variation on feeding behavior and life stage.
Description of the larva of Mnesarete pudica (Hagen in Selys, 1853) (Odonata: Calopterygidae) and notes on known genera of South American Calopterygidae larvae
The final instar larva of Mnesarete pudica is described and illustrated based on reared specimens collected in Brazil. This species can be distinguished from others by presenting: a) five palpal and…
Mate recognition in Acanthagrion truncatum (Odonata: Coenagrionidae)
The hypothesis that male- male interactions are misdirected sexual behavior and that sympatric morphologically similarspecies may represent visual interference for mate searching males is supported.
