ABSTRACT The objective of this study was to evaluate the effect of the construction of the Jirau hydroelectric plant on the anopheline species, in Porto Velho, Rondonia, Brazil. For this, sampling was carried out in 23 locations in the pre (2004) and 23 after construction (2018) phases in the hydroelectric dam's coverage area, performed by human landing catch between 6:00 pm and 10:00 pm. We found 14 anopheline species. In the pre-construction phase, An. darlingi (73%) was the most abundant and after construction An. braziliensis (31.5%) was the most abundant. The T test indicated that there were no differences in the indexes – diversity (H '), richness (Sjack 1), equitability (J’) and dominance (d) of anophelines species - evaluated between the phases (p > 0.05). The spatio-temporal distribution of An. darlingi proved to be wide, with the highest density values observed in March (x¯w = 27.1) in the pre-construction phase and in the months of May (x¯w = 4) and July (x¯w = 3.1), post-construction. Differences in hematophagic activity peaks were observed between species and between phases. According to the data obtained in this study, the construction of the hydroelectric plant had little influence on the composition of anopheline species, however changes were observed in the spatio-temporal distribution of the An. darlingi and in the pattern of hematophagic activity of the species, which directly influenced the dynamics of malaria in the region.

Abstract Cercophana frauenfeldii Felder (Lepidoptera: Saturniidae), also known as the “Andean Moon Moth”, is a Neotropical species native to continental Chile whose larvae feed on species of the families Gomortegaceae, Laureaceae and Winteraceae. We describe and document C. frauenfeldii immature stages, namely, egg, its four larval instars, and chaetotaxy of the last instar, pupa and cocoon for the first time. In terms of its phenology, we extend its larval activity, originally described to occur between November and mid-December, to June until the end of January. We report the adult flight period depends on the species’ distributional range following two well-differentiated patterns: February to mid-April in Central-North Chile and April to June in Central-South Chile. Furthermore, we provide a unified view of its current distributional range and host plants (including the endangered tree Gomortega keule) through bibliographic data, field observations and laboratory rearing. Finally, we discuss aspects of the species’ conservation as part of the unique ecosystems found in the temperate forests of southern South-America.

ABSTRACT Insect damage to stored seeds is a challenge. Rhyzopertha dominica (Fabricius, 1792) (Coleoptera: Bostrichidae) is a major pest of seeds and grains in the world, but without record in seeds of the sudangrass (Sorghum drummondii (Poaceae)). The objective of this work was to report, for the first time, the occurrence and damage by R. dominica in S. drummondii seeds, sold in sealed packages in retail market. Four samples with 500 seeds each and without adult insects were separated from a package. The initial weight was obtained with a precision scale and the seeds were stored. The number of adult insects, the weight loss and the infestation rate of the seeds were evaluated 60 days later and the average between samples used to extrapolate the damage per package. An adult of R. dominica, on average, was obtained for each seven seeds and 54.06% of the seeds were damaged, with an average weight loss of 36.09%. This is the first report of R. dominica in sudangrass seeds and the damage inflicted shows that this insect may cause losses in the quantity and quality of seeds due to its rapid populational growth.

ABSTRACT Members of the Hydrophilidae, one of the largest families of aquatic insects, are potential models for the biomonitoring of freshwater habitats and global climate change. In this study, we describe the morphology of the male reproductive tract in the water scavenger beetle Tropisternus collaris. The reproductive tract in sexually mature males comprised a pair of testes, each with at least 30 follicles, vasa efferentia, vasa deferentia, seminal vesicles, two pairs of accessory glands (a bean-shaped pair and a tubular pair with a forked end), and an ejaculatory duct. Characters such as the number of testicular follicles and accessory glands, as well as their shape, origin, and type of secretion, differ between Coleoptera taxa and have potential to help elucidate reproductive strategies and the evolutionary history of the group.

ABSTRACT A bilateral gynandromorph of Spodoptera frugiperda was reported for the first time from Minas Gerais State, Brazil. The specimen with this trait was found among the progeny of a laboratory rearing population and exhibited dimorphism in the antennae, wings, head, thorax, and abdomen. It had a male left side and a female right side. Both the external and internal genitalia were typically those of a male.

ABSTRACT This study aims to report the occurrence of Heilipus draco in seeds of Ocotea puberula, and to describe the main injuries caused to the seeds and the effects on germination, as well as the occurrence of parasitoid hymenopterans. To this end, fruits of seven trees were selected, in the extreme south of the Atlantic Forest, Brazil. Fruit collection was carried out weekly in the middle third of the canopy, forming lots, from the beginning of fruit formation until total dehiscence, for two years. In order to examine the damage caused by the granivorous insects inside the fruits, 100 fruits were sectioned taking into account the batch/year with the aid of a scalpel and analyzed using a binocular stereomicroscope. In the same way, 144 fruits from each lot/year were stored individually in transparent plates in order to verify the occurrence and identification of species of granivorous insects. The proof of the influence of the injury caused to the seeds by the granivorous insects was carried out by the germination test, with four replications of 25 seeds, comparing seeds with and without oviposition holes. The species H. draco was found to be associated with the fruits of O. puberula. The egg-layings are endophytic, carried out directly on the seed. Larval parasitism of Hymenoptera Bracon, Omeganastatus, Scambus and Triapsis was observed. It is concluded that the cycle from egg to adult takes place inside the seed of O. puberula, and the injuries caused by the larvae decrease germination.

Abstract The interest in and use of Aedes (Stegomyia) aegypti (Linnaeus) (Diptera: Culicidae) insectary lines increased in most laboratories around the world since the recognition of the transmission of human and animal pathogens by this mosquito species, resulting in further scientific research on tropical diseases and vectors, and the development of chemical and biological products for mosquito populations control. In recent years, approaches to mosquito populations reduction have focused on new technologies that include the release of Wolbachia-infected lines, genetically modified vector and insects subjected to radiation in the Sterile Insect Technique. In order to evaluate some of these techniques, it is essential to count with wild A. aegypti populations and the reference strain, accurately identified, maintained under laboratory conditions. This work proposes a new tool to monitor possible exchanges between reference mosquito strain and wild native populations of A. aegypti in neighboring areas, or between different lines in the same insectary. We aligned and compared ND5 gene fragments of A. aegypti from diverse sources, finding a region with putative Single Nucleotide Polymorphisms between individuals of Rockefeller (Rock) strain and different wild A. aegypti populations. These polymorphic sites in the molecular marker, allowed us to discriminate Rock reference strain from the wild A. aegypti haplotypes found in the southeast of Argentina and bordering areas with Brazil, Uruguay and Paraguay, and it can be useful as a tool for regulatory entities of mosquito insectaries at different Arthropod Containment Levels.

A new species of Thraulodes Ulmer 1920 is described based on nymphs and imagos from Tapias river, Caldas department, Colombia. The mature nymphs were reared until the emergence of the imagos. Thraulodes latinus sp. n. can be distinguished from other species of the genus by: In males, the forewing without cross veins basal to bullae and with 11-14 cross veins distal to bullae, abdominal and legs color pattern, styliger plate redounded, with a long and digitiform median projection and shape of penes with apicolateral area forming an “ear-like” projection. In nymphs, the claws with eight denticles and the general coloration pattern.
