Novel protocol to identify true hybrids in normal oleate x high oleate crosses in peanut
Provedor de dados: 69
Autores: Wang,Chuan Tang; Yu,Shan Lin; Zhang,Shu Wei; Wang,Xiu Zhen; Tang,Yue Yi; Zhang,Jian Cheng; Chen,Dian Xu.
A novel hybrid identification protocol was developed for F0:1 peanut seeds resulting from crosses between normal oleate cultivars with wild type FAD2B gene and high oleate genotypes with an A insertion in FAD2B gene. Presence of a series of overlapped peaks in trace file of the PCR product amplified with bF19/R1 primers was an indication of hybridity. This protocol may facilitate high oleate breeding and genetic studies in peanut.

The use of PCR-RFLP as an identification tool for two closely related species of bats of genus Platyrrhinus
Provedor de dados: 74
Autores: Ferreira,Juliana Machado; Martins,Felipe de Melo; Ditchfield,Albert; Morgante,João Stenghel.
The bat species Platyrrhinus lineatus and P. recifinus (Phyllostomidae: Stenodermatinae) are ecologically important because of their capacity for seed dispersal. P. recifinus is endemic to the Atlantic rain forest and is considered vulnerable by the IUCN. The lack of distinct morphological features makes identification of the two species a difficult task. This study was aimed at testing the hypothesis that these are actually two distinct species by using PCR-RFLP of the mitochondrial cytocrome b gene. The results showed no shared haplotypes, demonstrating that these are, in fact, two distinct species. No polymorphism was obtained for P. recifinus, which could be a sign of low genetic diversity in this threatened species.

Plantas invasoras hospedeiras de Orthezia praelonga Douglas (Hemiptera: Ortheziidae) em pomares de Citrus nos municípios de Limeira e Mogi Mirim (SP).
Provedor de dados: 14
Autores: SKORUPA, L. A.; CESNIK, R.
A cochonilha Orthezia praelonga, também conhecida como "piolho branco", um importante inseto associado à cultura do Citrus no Brasil, é responsável por prejuízos na cultura em vários estados brasileiros (Cassino et al., 1991). Os danos causados pelo inseto estão relacionados à sucção da seiva, bem como a inoculação de substâncias toxicogênicas que interferem no desenvolvimento das plantas, ao mesmo tempo em que promovem a queda das folhas e dos frutos. A proliferação do fungo Capnodium sp. ("fumagina") nas excretas da cochonilha, depositadas sobre as partes vegetativas e reprodutivas das plantas, também é considerada um fato danoso, uma vez que compromete a eficiência dos processos respiratórios e fotossintéticos da planta (Lima, 1981). Além do Citrus, o...

Contributions to the Coordinated Control of Two Robotic Arms for Underwater Manipulation of Deformable Biological Specimens
Provedor de dados: 5
Autores: Leborne, Francois.
The research carried out in the scope of this doctorate degree aims to develop innovative techniques to improve the collection of biological and mineral samples underwater using robotic manipulators. The end goal is to enhance the handling by robotic means in order to maximise sample quality provided to marine scientists. The proposed techniques are based on an in-depth analysis of the robotic arm actuators used in most recent underwater intervention vehicles, in order to improve the accuracy of the positionning of the tools held by the manipulator arms. An instrumented tool has also been developed with the aim to measure the reaction forces and adapt the interaction between the arm's end-effector and its environment to improve samples handling. These...

Vibrio crassostreae sp nov., isolated from the haemolymph of oysters (Crassostrea gigas)
Provedor de dados: 5
Autores: Faury, Nicole; Saulnier, Denis; Thompson, F; Gay, Melanie; Swings, J; Leroux, Frederique.
Polyphasic analysis of five new Vibrio isolates originating from the haernolymph of diseased cultured oysters is described. The new isolates were closely related to Vibrio splendidus, having 98 % 16S rRNA gene sequence similarity. gyrB phylogenetic analysis, fluorescent amplified-fragment length polymorphism (FAFLP) fingerprinting and DNA-DNA hybridization experiments clearly showed that the new isolates form a tight genomic group that is different from the currently known Vibrio species. It is proposed to accommodate these isolates in a novel species, Vibrio crassostreae sp. nov. (type strain LGP 7(T) =LMG 22240(T)=Clp 108327(T)). Phenotypic and chemotaxonomic features that differentiate V. crassostreae from other known Vibrio species include arginine...

Autores: Bruni, V; Crisafi, E; Maugeri, T; Zaccone, R.
110 Vibrio strains were isolated, at various times of the year, from samples of sea-water supply, breeding-tank water and discarded fish used as food at the breeding stations. From the results obtained by the biochemical and cultural tests, it was possible to identify most of the isolated strains as Vibrio anguillarum . Strains with intermediate characteristics, above-all positive saccharose, proved to be numerous. The authors discuss the occurrence, in particular environments such as those being studied, of atypical or intermediate vibrio strains which are difficult to classify.

Olleya marilimosa gen. nov., sp nov., an exopolysaccharide-producing marine bacterium from the family Flavobacteriaceae, isolated from the Southern Ocean
Provedor de dados: 5
Autores: Nichols, Carol Mancuso; Bowman, John; Guezennec, Jean.
A Gram-negative, aerobic, gliding, orange-yellow marine bacterium was isolated from particulate material sampled from the Southern Ocean. This strain produced an exopolysaccharide in liquid culture. 16S rRNA gene sequence analysis showed that this isolate was a member of the family Flavobacteriaceae, but represented a separate lineage. Major whole-cell fatty acids included i15:1 omega 10c, i15:0, beta-OH i15:0, a15:1 omega 10c, 15:0 and alpha-OH i15:0. The G+C content of the DNA was 49 mol%. Based on phylogenetic, phenotypic, chemotaxonomic and genotypic analyses, this bacterium was placed in a novel taxon as Olleya marilimosa gen. nov., sp. nov. with type strain CAM030(T) (=ACAM 1065(T)=CIP 108537(T)).

Autores: Lai, Adelene; Singh, Randolph; Kovalova, Lubomira; Jaeggi, Oliver; Kondić, Todor; Schymanski, Emma L.
Background Applying non-target analysis (NTA) in regulatory environmental monitoring remains challenging—instead of having exploratory questions, regulators usually already have specific questions related to environmental protection aims. Additionally, data analysis can seem overwhelming because of the large data volumes and many steps required. This work aimed to establish an open in silico workflow to identify environmental chemical unknowns via retrospective NTA within the scope of a pre-existing Swiss environmental monitoring campaign focusing on industrial chemicals. The research question addressed immediate regulatory priorities: identify pollutants with industrial point sources occurring at the highest intensities over two time points. Samples from...

L'absorption Dynamique des Ondes de Gravité en Régime Instationnaire
Provedor de dados: 5
Autores: Maisondieu, Christophe.
This study deals with the dynamic absorption of water waves. We focus here our attention on the case of a simple devce, a 2D piston, in order to exploit the well-known expressions of the potential as far as possible in the design of new absorption laws. We consider a semi-infinite two dimensional wave tank closed by a mobile vertical plane. An unsteady wave train generated at infinity impiges on this plate. The problem of the dynamic absorption consists in finding, in real time, the velocity to be given to the plate so that the radiated and the reflected wave trains should cancel each other. We propose here to derive this velocity from the forces measured on the plate. We first derive a frequency dependant transfer function between the optimal velocity of...

Autores: Bing,Li; Wu,Xiu-Ping; Feng,Yin; Wang,Yu-Jin; Liu,Hong-Chen.
This study aims to explore the role of palatal rugae pattern in forensic identification by coding of palatal rugae characteristics, and to construct a forensic identification system for oral palatal rugae. One hundred models were included in this study for a systemic coding of palatal rugae pattern based on the shape, quantity, location, and distribution of palatal rugae. Among the involved 100 models, palatal rugae types varied among individuals and palatal rugae pattern was different between men and women, even between two sides in the same individual. Palatal rugae pattern can be used for forensic identification of oral soft tissue and this study proposes a new means for the identification by coding of palatal rugae pattern based on the shape, quantity,...

The exotic jellyfish Blackfordia virginica introduced into the Netherlands (Cnidaria: Hydrozoa)
Provedor de dados: 16
Autores: Faasse, M.A.; Melchers, M.
In August 2014 the exotic jellyfish Blackfordia virginica was captured in the harbour of Amsterdam. This is the first confirmed record of this species in the Netherlands, although in October 2013 a possible specimen was filmed and released. This indicates that the species might be established in the Amsterdam area, although repeated introduction with ballast water cannot be ruled out. In September 2014 hydrozoan polyp colonies closely resembling those of B. virginica were collected near IJmuiden in the Noordzeekanaal, a canal connecting Amsterdam with the North Sea at IJmuiden.

Autores: Cornelius, P.F.S.
The hydranths of six species of hydroids of the family Haleciidae from NW Europe are described from life and compared. Notes are given on the hydranths of three other species, and general taxonomic comments on some others. Hydranth character-states are useful in defining and distinguishing Halecium species, but the characters may not be useful in routine identification by non-specialists. Halecium undulatum is recorded for the first time from Sweden, and from three localities in Norway whence there was just one previous record. Halecium halecinum may breed year-round in British waters.

The rediscovery of Cervera atlantica (Johnson, 1861) (Cnidaria: Octocorallia): notes on its identification, ecology and geographical distribution
Provedor de dados: 16
Autores: Williams, R.B.
Cervera atlantica, a small stoloniferan octocoral, was described as Cornularia atlantica by James Yate Johnson in 1861 from Funchal, Madeira. It then remained unrecognized until 1972 when I discovered it on the Mediterranean coast of Spain. I have since confirmed its existence at the type locality and have traced its distribution around Madeira, throughout the Canary Islands, and on Portuguese and English coasts. In the Mediterranean Sea, I have found it along Spanish and French coasts, among the Balearic Islands and on the coast of Cyprus. Cervera atlantica is cryptic and photophobic, living under stones in shallow water (usually at 0-2 m) or in crevices and caves in massive intertidal rocks, protected from direct sunlight. Intolerant of rough water, it...

Alternative techniques to study characters of the genitalia in Lepidoptera
Provedor de dados: 82
Autores: Dias,Fernando M S; Casagrande,Mirna M; Mielke,Olaf H H.
The present note aims to describe two alternative methods for observing genitalia in Lepidoptera. The first one provides means to examine both male and female genitalia without spoiling the scales of the abdomen, preserving it attached to the thorax and aesthetically similar to an unexamined specimen. The second one provides ways of observing certain characters on the male genitalia in a non-destructive way, and does not depend on time-consuming removing and dissection of the abdomen. It is expected that the presented techniques will help on morphological studies and on identifying similar species which consistently differ in genitalic armatures.

Serum from a dog immunized with blood plasma from a B. gibsoni-infected dog, putatively containing secreted antigens, was used to screen a cDNA expression library. A novel gene encoding BgSA1 was identified from the isolated clones. The serum raised in mice immunized with the recombinant BgSA1 expressed in Escherichia coli could recognize a native parasite protein with a molecular mass of 59 kDa. Comparing with the previously established ELISA with recombinant P50 as antigen, the ELISA with recombinant BgSA1 as the antigen was more sensitive when they were used to detect field samples. Moreover, a sandwich ELISA with anti-BgSA1 antibodies could detect the circulating BgSA1 in a serial blood plasma from a dog experimentally infected with B. gibsoni. These...

Armina wattla Marcus and Marcus, 1967 and Armina abbotti Thompson, Cattaneo and Wong, 1990 were proposed by Ardila and Valdés (2004) to be junior synonyms of Armina muelleri (Ihering, 1886). A detailed anatomical review of these species (radula, reproductive system) and their distribution range revealed that A. wattla is a valid species and A. abbotti is a synonym of the former. Literature references to Armina tigrina Rafinesque, 1814 in the east coast of North America are misidentifications of some specimens of A. wattla.

Paternity test in "Mangalarga-Marchador" equines by DNA-fingerprinting
Provedor de dados: 86
Autores: ANUNCIAÇÃO,CARLOS EDUARDO; ASTOLFI-FILHO,SPARTACO.
GC-rich molecular minisatellite probes isolated from the human genome have presented a poor ability for individualization in horses. In this study new DNA sequences were isolated which could be used in paternity tests in horses. Genomic DNA from "Mangalarga-Marchador" horses was treated with restriction enzymes that preferentially digest non-repetitive sequences, so preserving the structure where mini and microsatellites are located. Four clones (S01, S05, S07 and S09) selected from a genomic library screened with a (TG)n oligonucleotide showed similar hybridization profiles generating bands of DNA-fingerprinting type. Using these probes the individualization power obtained was 10-8, which is 10(5)fold higher than that obtained with M13, another GC-rich...

Identification of Supply Models of Retailer and Manufacturer Oligopoly Pricing
Provedor de dados: 31
Autores: Villas-Boas,   Sofia Berto; Hellerstein,   Rebecca.
This note outlines conditions under which we can identify a vertical supply model of multiple retailers' and manufacturers' oligopoly-pricing behavior. This is an important question particularly when the researcher believes, contrary to the traditional assumption followed in the empirical literature, that retailers may not be neutral pass-through intermediaries. We show that a data-set of an industry's product prices, quantities, and input prices over time is sufficient to identify the vertical model of retailers' and manufacturers' oligopoly-pricing behavior given nonlinear demand, for homogeneous-products industries, and given multi-product firms, for differentiated-products industries.

IDENTIFICATION OF ECONOMIES OF SCOPE IN A STOCHASTIC PRODUCTION ENVIRONMENT
Provedor de dados: 31
Autores: Curtis,   Rita E.; Sarmiento,   Camilo.
This paper extends the definition of economies of scope to multioutput firms that face an uncertain production environment.  Identification of economies of scope in this environment, however, requires separability assumptions on the technology. These identification restrictions are demonstrated in the paper, and for each identification restriction the definition of economies of scope is generalized to the case of uncertain production and risk aversion.

Autores: Rubio,MS; Penha Fº,RAC; Almeida,AM; Barbosa,FO; Berchieri Jr,A.
ABSTRACT The incidence of foodborne diseases caused by the genus Salmonella spp. in industrialized countries is often high in epidemiological surveys. Obtaining a rapid diagnostic test for identification of bacteria is crucial in order to rapidly implement control measures to contain bacterial spread, to reduce losses in animal production and to avoid risks from food-borne infections to human health. The aim of this study was to standardize duplex real-time PCR using SYBr Green I for differential and quantitative diagnosis of S. Typhimurium and S. Enteritidis. According to the experiment, the melting temperature of 85°C was observed for a 206bp amplified product when S. Enteritidis DNA was added to the reaction. S. Typhimurium DNA showed that the melting...

Autores: Deffert, Flávia; Agustini, Bruna Carla; Picheth, Geraldo; Bonfim, Tania Maria Bordin.
Fructooligosaccharides are catalyzed by β–fructofuranosidase enzyme, produced by many microorganisms. However, in order to achieve a more profitable, low time-consuming process with lower cost, researchers have sought alternatives. This study aimed to select and identify yeasts able to produce fructooligosaccharides and evaluate the influence of pH and temperature on their synthesis. Yeast suspensions, solutions of 500 g L-1 sucrose and three values of pH (4.5, 5.5, and 6.5) and temperature (40, 50, and 60ºC) were tested. Yeast species were identified by molecular techniques. Among 141 yeast isolates from grapes, 65 were able to synthesize fructooligosaccharides. The maximum concentration of fructooligosaccharides was 4.8% (w v-1), and Saccharomyces...

Identification of Tibicen cicada species by a Principal Components Analysis of their songs
Provedor de dados: 42
Autores: Ohya,Eiji.
Specific identification of three Tibicen cicadas, T. japonicus, T. flammatus and T. bihamatus, by their chirping sounds was carried out using Principal Components Analysis (PCA). High quality recordings of each species were used as the standards. The peak and mean frequencies and the pulse rate were used as the variables. Out of 12 samples recorded in the fields one fell in the vicinity of T. japonicus and all other were positioned near T. bihamatus. Then the cluster analysis of the PCA scores clearly separated each species and allocated the samples in the same way.

Autores: Lima,Élison Fabrício Bezerra; Monteiro,Renata Chiarini; Zucchi,Roberto Antonio.
Little is known about the Thysanoptera fauna from Brazilian Mid-North. In spite of being a region with at least three biomes and some ecotones, the studies on this insect order in the region are related to associations to a few cultivated plant species. On Fabaceae, plant family with the second largest number of records of thrips species associated in Brazil and huge economic importance for Mid-North, there are thrips records only on cowpea (Vigna unguiculata (L.) Walp.). Due to the lack of knowledge on the Thysanoptera fauna in such a diverse area and the importance of crops of this family in the region, this research aimed to survey the thrips species associated to Fabaceae of agricultural importance in areas of Cerrado and Amazon-Caatinga ecotone in...

An illustrated key to male Actinote from Southeastern Brazil (Lepidoptera, Nymphalidae)
Provedor de dados: 49
Autores: Francini,Ronaldo Bastos; Penz,Carla M.
In certain times of the year, Actinote butterflies can be vastly abundant in Southeastern Brazil, thus representing conspicuous denizens of our fauna. Their wing coloration allows for the recognition of five major patterns, which probably resulted from mimicry. Furthermore, examination of series of field-collected and reared specimens clearly demonstrates a high intra-specific variation in wing color pattern. In concert, inter-specific resemblance (mimicry) and intra-specific variation make it difficult to discriminate Actinote species from each other. This key aims at providing a tool for identification of male Actinote. To that effect, we provide diagnostic characters and illustrations of wings and male genitalia for 22 species. We hope that the clear...

Identification of animals that are decomposing or have been run over or burnt and cannot be visually identified is a problem in the surveillance and control of infectious diseases. Many of these animals are wild and represent a valuable source of information for epidemiologic research as they may be carriers of an infectious agent. This article discusses the results obtained using a method for identifying mammals genetically by sequencing their mitochondrial DNA control region. Fourteen species were analyzed and identified. These included the main reservoirs and transmitters of rabies virus, namely, canids, chiroptera and primates. The results prove that this method of genetic identification is both efficient and simple and that it can be used in the...

Rapid identification of Mycobacterium tuberculosis complex by a novel hybridization signal amplification method based on self-assembly of DNA-streptavidin nanoparticles
Provedor de dados: 58
Autores: Wang,Haihe; Zhao,Chunyan; Li,Fan.
Rapid detection of Mycobacterium tuberculosis complex (MTBC) is a critical step in controlling tuberculosis (TB). In this study, we used IS6110 as the specific identification target to develop a novel hybridization signal amplification method (HSAM) for the rapid and direct detection of MTBC from clinical sputum specimens. This system consists of magnetic bead-linked capture probes for target isolation, dextranbased nanoparticles for amplifying the reporter molecule (biotinylated-FITC), and detection probes (2B-DNA) for binding the nanoparticles. Both the capture and detection probes were specific to the IS6110 target sequence. Our results determined that as few as 10 copies of the IS6110 sequence or 10 M. tuberculosis bacteria could be detected,...

Provedor de dados: 58
Autores: Martinati,Juliana Camargo; Pacheco,Flávia Tereza Hansen; Miranda,Vitor Fernandes Oliveira de; Tsai,Siu Mui.
Strains of Xylella fastidiosa from several hosts (coffee, citrus, grape, almond, oleander, peach, plum, etc.) were characterized by analyzing the content of the nucleotide sequences of 16S-23S rDNA (coding for a small subunit ribosomal RNA) spacer region (ITS). Current methods for sequencing the ITS region yields partial sequences that do not contribute with significant information. According to this fact, new primers have been designed in order to obtain a complete sequence and facilitate the sequencing. The complete 16S-23S sequences from 08 strains were amplified through PCR using the primers designed in our lab. The 16S-23S sequences obtained were compared with 52 others sequences entries in GenBank database. The results revealed a higher level of...

In the aviculture industry, the use of Lactobacillus spp. as a probiotic has been shown to be frequent and satisfactory, both in improving bird production indexes and in protecting intestine against colonization by pathogenic bacteria. Adhesion is an important characteristic in selecting Lactobacillus probiotic strains since it impedes its immediate elimination to enable its beneficial action in the host. This study aimed to isolate, identify and characterize the in vitro and in vivo adhesion of Lactobacillus strains isolated from birds. The Lactobacillus spp. was identified by PCR and sequencing and the strains and its adhesion evaluated in vitro via BMM cell matrix and in vivo by inoculation in one-day-old birds.

ABSTRACT Tomato is one of the most important vegetables in the world. Decay after harvest is a major issue in the development of tomato industry. Currently, the most effective method for controlling decay after harvest is storage of tomato at low temperature combined with usage of chemical bactericide; however, long-term usage of chemical bactericide not only causes pathogen resistance but also is harmful for human health and environment. Biocontrol method for the management of disease after tomato harvest has great practical significance. In this study, antagonistic bacterium B-6-1 strain was isolated from the surface of tomato and identified as Enterobacter cowanii based on morphological characteristics and physiological and biochemical features combined...

ABSTRACT Matrix Assisted Laser Desorption/Ionization and Time of Flight mass spectrometry (MALDI-TOF MS) is a powerful tool for the identification of bacteria through the detection and analysis of their proteins or fragments derived from ribosomes. Slight sequence variations in conserved ribosomal proteins distinguish microorganisms at the subspecies and strain levels. Characterization of Leptospira spp. by 16S RNA sequencing is costly and time-consuming, and recent studies have shown that closely related species (e.g., Leptospira interrogans and Leptospira kirschneri) may not be discriminated using this technology. Herein, we report an in-house Leptospira reference spectra database using Leptospira reference strains that were validated with a collection...

Candida dubliniensis is an emerging pathogen capable of causing superficial as well as systemic infections. Due to its close similarity to C. albcians, conventional methods based on phenotypic traits are not always reliable in identification of C. dubliniensis. In this study, we developed a PCR-restriction fragment length polymorphism (RFLP) assay to identify and discriminate between the two closely related species. The D1/D2 region of 28S rDNA was amplified by PCR and enzymatically digested by ApaI and BsiEI respectively. PCR products of both species were digested into two fragments by ApaI, but those of other yeast species were undigested. BsiEI cut the PCR products of C. albicans into two fragments but not those of C. dubliniensis. Thus two species were...

Provedor de dados: 58
Autores: Maldonade,Iriani R.; Scamparini,Adilma R. P.; Rodriguez-Amaya,Délia B.
The objective of the present study was to select and identify yeasts from Brazil capable of producing carotenoids. Pigmented yeasts were isolated from soil, leaves, fruits, flowers and a processed product. The samples were incubated at 30ºC in Erlenmeyer flasks, containing YM broth. After 48 hours, they were inoculated in Petri dishes with YM agar, and incubated at 30ºC during 120 hours. The yeast colonies, which presented yellow to red coloration, were transferred to culture tubes containing YM agar, and incubated at 30ºC for 72 hours. Out of 242 samples, only five had yellow to red color at high intensity. These highly pigmented yeasts were re-isolated in Petri dishes with YM agar and then transferred to tubes with GPYM agar. Identification through...

Autores: Marroki,Ahmed; Zúñiga,Manuel; Kihal,Mabrouk; Pérez-Martínez,Gaspar.
Nineteen strains of Lactobacillus isolated from goat's milk from farms in north-west of Algeria were characterized. Isolates were identified by phenotypic, physiological and genotypic methods and some of their important technological properties were studied. Phenotypic characterization was carried out by studying physiological, morphological characteristics and carbohydrate fermentation patterns using API 50 CHL system. Isolates were also characterized by partial 16S rDNA sequencing. Results obtained with phenotypic methods were correlated with the genotypic characterization and 13 isolates were identified as L. plantarum, two isolates as L. rhamnosus and one isolate as L. fermentum. Three isolates identified as L. plantarum by phenotypic characterization...

Characterization of pathogenic Aeromonas veronii bv. veronii associated with ulcerative syndrome from Chinese longsnout catfish (Leiocassis longirostris Günther)
Provedor de dados: 58
Autores: Cai,Shuang-Hu; Wu,Zao-He; Jian,Ji-Chang; Lu,Yi-Shan; Tang,Ju-Feng.
273 bacterial strains were isolated from 20 Chinese longsnout catfish samples. The biochemical characteristics of all strains conformed to the species description of Aeromonas veronii bv. veronii on the basis of Vitek GNI+ card. Furthermore, 16S rDNA, gyrB and rpoD sequences of the representative strain PY50 were sequenced and showed high similarity with A. veronii bv. veronii in Genbank. Antibiotic-resistance of the representative strain PY50 was assessed by the Kirby-Bauer disk diffusion method, and the results showed it was susceptible and moderately susceptible to 13 and 4 of the 21 antimicrobial agents tested. Extracellular products of strain PY50 contained gelatinase, lecithinase, elastase, most of lipase and lipopolysaccharide. Virulence of strain...

Thrips on fabaceous plants and weeds in an ecotone in northeastern Brazil
Provedor de dados: 65
Autores: Lima,Élison Fabrício Bezerra; Zucchi,Roberto Antonio.
ABSTRACT: Thrips (Thysanoptera) on 33 species of Fabaceae (ornamental and forage) and some weed species were surveyed in areas of caatinga-cerrado ecotone in northeastern Brazil. Twenty species of thrips were identified, all of which are associated for the first time with the plants sampled in this study, totaling 26 new host associations, based on collections of immatures. Five species are probably new to science, illustrating the diversity of thrips in the region. A few thrips species that also occur as pests in other regions of Brazil are discussed. Our data extend the distribution area of thrips species and provide basic information on their associated plants.
