PRIMEIRO REGISTRO DE Psyllaephagus bliteus PARASITANDO Glycaspis brimblecombei EM CHAPADÃO DO SUL, MS

Psyllaephagus bliteus Riek, 1962 (Hymenoptera: Encyrtidae) é uma vespa de origem australiana que parasita ninfas de Glycaspis brimblecombei Moore, 1964 (Hemiptera: Psyllidae). No Brasil, a presença de ambos foi registrada pela primeira vez no Estado de São Paulo em 2003 e, posteriormente, sua ocorrência foi registrada nos estados do Paraná, Goiás, Minas Gerais, Santa Catarina, Rio Grande do Sul e Mato Grosso. No manejo dessa praga, P. bliteus é uma das formas mais promissoras de controle biológico clássico, uma vez que G. brimblecombei tem causando danos significativos na produção florestal. A ocorrência destes insetos na região nordeste de Mato Grosso do Sul foi constatada no Município de Chapadão do Sul, em povoamento de Eucalyptus camaldulensis, confirmando o potencial dispersivo e adaptativo de ambos

EFFECT OF A THERMOGENIC SUPPLEMENTATION ON POST AEROBIC EXERCISE HEMODYNAMIC RESPONSES IN HEALTHY YOUNG MEN

Introduction: The use of food supplements with esthetic or performance-enhancing goals has been largely investigated. Thermogenics are supplements that increase energy expenditure through thermogenesis and are widely consumed by individuals seeking to improve body composition and exercise performance. Objective: To evaluate the effects of a commercially available thermogenic supplement on post-exercise blood pressure responses. Materials and Methods: Twenty-seven healthy thermogenic supplements users participated in the study. Nine were assigned in the control group (21.67 ± 1.87 years), nine in the thermogenic group (24.00 ± 4.18), and nine in the placebo group (23.67 ± 3.04). The volunteers performed a treadmill aerobic exercise session for 60 minutes at 65 to 85% max heart rate. The hemodynamic variables were measured at rest and during 60 minutes in the post-exercise recovery. The normality of the data was evaluated using the Shapiro-Wilk test. Baseline momentum and post-exercise recovery were analyzed using the two-way ANOVA test (group versus time factors), with Bonferroni post-hoc test. The level of statistical significance was set at p 5 mmHg, which reportedly plays an important role in cardiovascular diseases. Conclusion: The use of the thermogenic Lipo 6 Black Ultra Concentre Nutrex ® did not alter PEH in healthy youngsters. However, since an increase in the blood pressure was observed, this supplementation must be administered with caution

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

First record of Hexacladia hilaris Burks (Hymenoptera: Encyrtidae) in Brazil and association with Chinavia erythrocnemis (Berg) (Heteroptera: Pentatomidae)

Hexacladia hilaris Burks (Hymenoptera: Encyrtidae) is a parasitoid associated to several stink bug species in Costa Rica, Porto Rico and United States. In April 2018, at the Passo Fundo (28º15’46” S / 52º24’24” O), Rio Grande do Sul state, Brazil, specimens of H. hilaris were collected from Chinavia erythrocnemis (Berg) (Heteroptera: Pentatomidae). This is the first record of this parasitoid in South America as well as its association with C. erythrocnemis

Natural parasitism of Hexacladia smithii Ashmead (Hymenoptera: Encyrtidae) on Euschistus heros (F.) (Hemiptera: Pentatomidae): new record from Mato Grosso State, Brazil

The neotropical stink brown bug, Euschistus heros (F.) (Hemiptera: Pentatomidae), is an insect pest to soybean crops in Mato Grosso State, Brazil. In this region, synthetic insecticides are frequently used for insect control. An alternative to the indiscriminate use of insecticides is the biological control with parasitoids. Thus, the objective of this study was to conduct the survey of parasitoids that use E. heros adults as hosts. Random samples were conducted during the harvests of 2009/10 and 2010/11 in two farms that produce soybean (conventional system) in Tangará da Serra, Mato Grosso State, Brazil. The total number of collected E. heros was: 297 (Field 1) and 293 (Field 2) in 2009/10 and 295 (Field 1) and 376 (Field 2) in 2010/11. Of these, 1.50 (Field 1) and 13.99% (Field 2) were parasitized in 2009/10 and 8.47 (Field 1) and 7.45% (Field 2) in 2010/11. The parasitoids found were Hexacladia smithii Ashmead (Hymenoptera: Encyrtidae) in both fields. This is the first record of parasitism in E. heros adults in the state of Mato Grosso, Brazil
