Knowledge on biodiversity is fundamental for conservation strategies. The Brazilian Pampa region, located in subtropical southern Brazil, neglected terms of conservation, and knowledge its fragmented. We aim to answer the question: how many, which, species occur Pampa? In a collaborative effort, we built lists plants, animals, bacteria, fungi that Pampa. included information distribution patterns, main habitat types, status. Our study resulted referenced totaling 12,503 (12,854 taxa, when...
Climate change ranks among the most important issues globally, affecting geographic distributions of vectors and pathogens, inducing losses in livestock production many other damaging effects. We characterized potential distribution ticks Rhipicephalus (Boophilus) microplus, an vector babesiosis anaplasmosis globally. evaluated shifts suitability patterns for this species two periods (2050 2070) under emissions scenarios (RCPs 4.5 8.5). Our results anticipate increases worldwide,...
The experiment was conducted throughout the year 2005, at Universidade Federal de Pelotas campus. objectives of study were to analyze decomposition rabbit (Oryctolagus cunniculus L.) with mean weight 2.67 Kg carcass and describe interaction insects acting on it, as well insect's potential use in legal medicine. We collected 5.239 insect specimens; 1.827 them obtained from larvae carcasses reared. specimens identified 20 species forensic importance. Lucilia eximia (Wiedemann, 1819) Chrysomya...
Fluctuations in seasonal patterns of horse fly populations were examined rainforests tropical South America, where the climate is seasonal. These evaluated with robust analytical models rather than identifying main factors that influenced fluctuations. We seasonality flies fields and lowland areas Pampa biome southern Brazil generalized linear models. also investigated diversity these sampling effort Malaise traps this over two years. All 29 species had clear regard to occurrence abundance,...
Abstract Horse flies (Diptera: Tabanidae) cause direct and indirect losses in livestock production are important vectors of pathogens. The aim this study was to determine the diversity seasonality horse fly species at an experimental farm Tacuarembó different departments Uruguay. For 20 months, systematic collections were performed two environments using Nzi Malaise traps. In addition, nonsystematic farms located Paysandú, Colonia. A total 3,666 collected, 16 identified. These included three...
Abstract Horse fly females (Diptera, Tabanidae) are hematophagous and can vector pathogens that affect livestock. Complexes of cryptic species common in Tabanidae, as exemplified by some Tabanus, including Tabanus triangulum occidentalis, both prevalent the Southern region Brazil. In this study, geometric morphometrics were employed to ascertain wing venation identification. It was demonstrated tool effectively differentiates T. from occidentalis coastal plain Rio Grande do Sul state,...
The blowfly species are important components in necrophagous communities of the Neotropics. Besides being involved degradation animal organic matter, they may serve as vectors for pathogens and parasites, also cause primary secondary myiasis. occurrence pattern these is well defined, yet it still not very clear which environmental factors determine structure assemblies. This paper was developed to evaluate influence mean temperature relative humidity variation abundance richness blowflies...
Dipteran larvae were collected from rabbit (Oryctolagus cunniculus L.) carcasses during the four seasons in 2005 southernmost state of Rio Grande do Sul, Brazil. The fed ground beef at ambient temperatures following collection carcasses. development each species under these conditions was estimated. most abundant Lucilia eximia (Wiedemann) and Chrysomya albiceps (Calliphoridae), they found all seasons. data fitted to a linear model that describes relationship between temperature...
In order to characterize the epigeic myrmecofauna in fields and vineyards physiographic region of Campanha, located Pampa biome, state Rio Grande do Sul, inventories were conducted on three farms. On each farm, samples collected environments: rows vineyards, spaces between adjacent areas, with vegetation similar that which preceded establishment crops. environment, 20 points sampled using pitfall traps. We 72 species distributed among 24 genera seven subfamilies. The study provides first...
Anaplasma marginale is transmitted biologically by infected ticks or mechanically biting flies and contaminated fomites. In tick-free areas, such as southern Uruguay, horseflies could be the principal vectors of this pathogen for bovines, causing anaplasmosis. The objective work was to detect presence A. MSP-5 PCR Sanger sequencing in most prevalent species obtained using different collection methods Colonia, Tacuarembó Paysandú, Uruguay. Eight horsefly were tested (Dasybasis missionum,...
The distribution of muscid species (Diptera) in grasslands fragments southern Brazil was assessed using null models according to three assembly rules: (a) negatively-associated distributions; (b) guild proportionality; and (c) constant body-size ratios. We built presence/absence matrices calculated the C-score index test distributions proportionality based on following algorithms: total number fixed lines (F L), fi xed columns C), effect average size populations along (W) for 5000...
AbstractThe examination of 145 specimens Pseudolynchia canariensis (74 males and 71 females) from 31 Columba livia captured between March April 2012 in the municipality Pelotas, southern Brazil, revealed an aggregated distribution hippoboscid flies. Prevalence mean intensity infestation were higher on younger hosts. Approximately 30% flies exhibited phoretic associations with skin mites families Epidermoptidae Cheyletidae as well chewing lice family Philopteridae. Myialges anchora...
Necrophagous Diptera associated with wild animal carcasses in southern Brazil. The aim of this study was to acquire a better knowledge concerning the diversity necrophagous that develop on carcasses. For purpose, decomposition six observed order collect and identify main species flies process. were found highways near cities Pelotas Capão do Leão initial stage decomposition, no significant injuries or prior larval activity. Four models represented study: two specimens Didelphis albiventris...
Foram realizadas coletas de tabanídeos ao longo quatro anos (2002-2006) no extremo sul do Rio Grande Sul, Brasil. Apresenta-se uma lista com 30 espécies, além chave pictórica e diagnoses para identificação dos 15 gêneros encontrados na região. Nove espécies são registradas pela primeira vez estado Sul.
The mosquito Aedes aegypti (Linnaeus, 1762) is the main vector of dengue and yellow fever viruses. Different methods have been used to control A. aegypti, including chemical biological tools. However, can lead a subsequent increase in mosquitoes' insecticide resistance, represents an important method as alternative usage. Larvae from Toxorhynchites genus (Diptera: Culicidae) are predators other mosquitoes represent potential natural biocontrol agent larvae. In present work, larval survival...
The purpose of this study was to evaluate the survival, development time and morphological measures immature Ophyra aenescens albuquerquei on different diets. Different proportions protein carbohydrates were offered for each species in 10 vials containing 30 eggs each. placed a germination chamber at 30°C, relative humidity above 75% photoperiod 12 hours. Every day vial removed mortality evaluated tenth length cephalic-pharyngeal skeleton (EC) body size (G) larvae that survived evaluated....
