Invasion origin, rapid population expansion, and the lack of genetic structure of cotton bollworm (Helicoverpa armigera) in the Americas

In 2013, Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) was officially declared as present in Brazil and, after two years, the species was detected in the Caribbean and North America. Information on genetic features and accurate distribution of pests is the basis for agricultural protection policies. Furthermore, such knowledge is imperative to develop control strategies, understand the geographical range, and genetic patterns of this species in the Americas. Here, we carried out the widest sampling of H. armigera in the South American continent and Puerto Rico, after we estimated the diversity, demographic parameters, and genetic structure. The Internal Transcribed Spacer 1 (ITS1) nuclear marker was used to investigate the presence of putative hybrids between H. armigera and H. zea, and they were observed at a frequency of 1.5%. An ABC analysis, based in COI gene fragment, suggested Europe as the origin of South America specimens of H. armigeraand following a movement northward through the Caribbean. Three mtDNA genes and three nDNA markers revealed high genetic diversity distributed without the defined population structure of H. armigera in South America. Most of the genetic variation is within populations with a multidirectional expansion of H. armigera among morphoclimatic regions. High genetic diversity, rapid population expansion, and hybridization have implications for pest management since they suggest that adaptive alleles are spread through wide areas in South America that favor rapid local adaptation of H. armigera to new and disturbed environments (e.g., in agricultural areas)9137378CAPES - Coordenação de Aperfeiçoamento de Pessoal e Nível SuperiorCNPQ - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPESP – Fundação de Amparo à Pesquisa Do Estado De São Paulo2014/10504-9; 2014/11495-3; 2015/02079-9; 2018/04478-6140866/2016-7; 309167/2015-900

Caracterização dos sistemas de produção de ovinos e caprinos na microrregião de Castanhal, Pará

O objetivo desse trabalho foi caracterizar os sistemas de produção de ovinos e caprinos na microrregião de Castanhal - Pará. Entre março de 2014 a maio de 2015 foram realizadas visitas a 60 propriedades criadoras de ovinos e caprinos da microrregião de Castanhal - PA, onde aplicou-se um questionário epidemiológico para obtenção de dados relacionados ao manejo produtivo, nutricional, sanitário e reprodutivo do rebanho, infraestrutura e gerenciamento das propriedades. O tipo de criação predominante era extensivo, com pastejo contínuo, com suplementação mineral somente em 46,6% das propriedades. Em 93,4% das propriedades o reprodutor era mantido junto com as fêmeas o ano inteiro, enquanto em apenas 3,4% utilizavam estação de monta e em 3,4% faziam monta controlada. As doenças relatadas como frequentes foram: parasitoses gastrointestinais (90%), afecções podais (80%), mortalidade de cordeiros (48,4%), linfadenite caseosa (31,7%), mastites (25%) e dermatite alérgica (20%). Também foram relatados abortos (10%), problemas respiratórios (6,7%), alterações nervosas (8,4%), ceratoconjuntivite (13,4%) e ectima contagioso (13,4%). A bovinocultura era a principal atividade desenvolvida pela maioria das propriedades do estudo e a ovinocaprinocultura secundária. Em 88,3% das propriedades não eram comercializados animais para o abate ou os reprodutores. Os resultados deste trabalho demonstraram que o nível de organização das criações de pequenos ruminantes era precário, sem utilização de técnicas de manejo e não possuíam assistência técnica, apresentando elevados índices de mortalidade, principalmente, pelas parasitoses gastrointestinais e problemas podais

Production and productivity components of hybrid rice dry compared to conventional three cultivars

This research aimed to evaluate the yield and productivity of Ecco rainfed compared to conventional cultivars BRS Primavera, BRS Sertanejaand Cambará in Vilhena and Cerejeiras cities, Rondonia state. The experiment was completely conducted in random with four replications. The experiments were conducted in November, 2009, one in the Experimental Farm at Faculdade da Amazônia, in Vilhena city, Rondonia state, located at latitude S 12°44'26" and longitude W 60°08'45", and the other at the Experimental Field of Faculdade da Amazônia in Cerejeiras-RO, located at S 13°11'19,6" latitude and W 060°51'43,9" longitude. The variables were: tillering, number of whole grains and chochos per panicle, 1000 grain weight, yield in bags of 60 kg per hectare and yield of whole grains. The hybrid cultivar Ecco is the most suitable for cultivation in the two regions, because it showed better tillering, greater efficiency in grain filling, greater weight of 1000 grains and consequently higher productivity in both regions, besides a high yield of whole grains in relation to other cultivars.A pesquisa teve por objetivo avaliar os componentes de produção e a produtividade do cultivar de arroz híbrido de sequeiro Ecco comparado as cultivares convencionais BRS Primavera, BRS Sertaneja e Cambará nos municípios de Vilhena e Cerejeiras-RO.

Genome of Herbaspirillum seropedicae Strain SmR1, a Specialized Diazotrophic Endophyte of Tropical Grasses

The molecular mechanisms of plant recognition, colonization, and nutrient exchange between diazotrophic endophytes and plants are scarcely known. Herbaspirillum seropedicae is an endophytic bacterium capable of colonizing intercellular spaces of grasses such as rice and sugar cane. The genome of H. seropedicae strain SmR1 was sequenced and annotated by The Paraná State Genome Programme—GENOPAR. The genome is composed of a circular chromosome of 5,513,887 bp and contains a total of 4,804 genes. The genome sequence revealed that H. seropedicae is a highly versatile microorganism with capacity to metabolize a wide range of carbon and nitrogen sources and with possession of four distinct terminal oxidases. The genome contains a multitude of protein secretion systems, including type I, type II, type III, type V, and type VI secretion systems, and type IV pili, suggesting a high potential to interact with host plants. H. seropedicae is able to synthesize indole acetic acid as reflected by the four IAA biosynthetic pathways present. A gene coding for ACC deaminase, which may be involved in modulating the associated plant ethylene-signaling pathway, is also present. Genes for hemagglutinins/hemolysins/adhesins were found and may play a role in plant cell surface adhesion. These features may endow H. seropedicae with the ability to establish an endophytic life-style in a large number of plant species

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI
