Pupas de mosca-dos-chifres, Haematobia irritans, em massas fecais de bovinos Nelore no Pantanal
SERENO, FABIANA TAVARES PIRES DE SOUZA;
Pesquisa Agropecuária Brasileira , 2000, DOI: 10.1590/S0100-204X2000000800023
Abstract: this study was carried out in embrapa-centro de pesquisa agropecuária do pantanal, corumbá, ms, brazil, from june/92 to may/94. manure samples of nelore breed were collected monthly to quantify if haematobia irritans (l.) populations and parasitoids were present. during two years, 588 h. irritans pupae were collected and 10% of parasitism were observed. the parasitoids species (hymenoptera) found were: spalangia nigroaenea (pteromalidae), s. endius (pteromalidae), rhoptromeris sp. (eucoilidae) and trichopria haematobiae (diapriidae). s. nigroaenea was responsible for 91.5% parasitism in pupae of h. irritans, this species and the other parasitoids species have low selectivity regarding host choice.

Abstract: we investigated the genealogy of the in situ conservation nucleus of the pantaneiro horse using dna microsatellites by evaluating 101 horses, the group consisting of 71 adult horses (3 stallions, 40 male and 31 mares) and 27 foals (14 colts and 13 fillies). genomic dna was extracted from hair roots and genotyped using 12 microsatellite markers (aht4, aht5, asb2, asb17, asb23, hms3 hms6, hms7, htg4, htg10, lex33 and vhl20). the number of alleles per locus varied from 6 to 13, with a mean of 7.8 and the expected heterozygosity ranged from 0.544 to 0.734 (mean 0.644). the vlh20, asb2, htg10, asb23 markers had a high (> 0.8) polymorphism information content and the total exclusion probability of the 12 microsatellite loci was 0.99. the genealogical study of the pantaneiro horse using genetic markers was efficient in detecting mistakes during paternity and maternity designation and is an important tool which can be used together with traditional systems of animal identification. the use of genetic markers is recommended in the systematic control of the genealogical registrations and conservation plans to improve genetic aspects of the pantaneiro horse.

Abstract: the aim of this study was to investigate the integrated effects of native pastures sealing with strategic control of gastrointestinal nematodes on body development of weaned nellore calves, studied between march 1992 and january 1993 in the pantanal region, brazil. two homogeneous groups of weanling calves were put on contiguous paddocks of native pastures with the same physiognomic characteristics and sealed for three and a half months. the paddock where the non-treated group was put, was previously used by cows that were rearing a calf for contamination of the pasture. the treated group remained with low levels of eggs per gram of feces (egf) during the whole experimental period. in the non-treated group, the egf diminished during the assay, ending with similar levels of the treated group. on body development, it was observed a lower body weight loss of the treated group during the dry season and a compensatory weight gain of the nontreated group on the subsequent rainy season. the mean body weight of the two groups was similar at the end of the trial.

Abstract: Entre mar o de 1992 e janeiro de 1993 realizou-se este estudo com o objetivo de avaliar o efeito integrado da veda do pasto nativo com o controle estratégico de nematóides gastrintestinais no desempenho corporal de bezerros Nelore pós-desmame no Pantanal da Nhecolandia, MS, Brasil. Dois lotes de animais recém-desmamados aos nove meses foram colocados em invernadas contíguas de pastagens nativas com as mesmas características fision micas, que foram vedadas por três meses e meio; a invernada do lote controle foi previamente pastejada por vacas com bezerro ao pé para contamina o. O lote tratado permaneceu com níveis muito baixos de ovos por grama de fezes durante todo o período experimental, e no lote controle foram diminuindo no decorrer do ensaio, terminando semelhantes. No desenvolvimento corporal, observou-se menor perda de peso do lote tratado durante a esta o seca e ganho de peso compensatório do lote controle na esta o chuvosa subseqüente. Os pesos médios dos dois lotes no final do experimento foram semelhantes.

Abstract: blood samples were collected from pantaneiro horses in five regions of mato grosso do sul and mato grosso states. arabian, mangalarga marchador and thoroughbred were also included to estimate genetic distances and the existing variability among and within these breeds by rapd-pcr (random amplified polymorphic dna - polymerase chain reaction) molecular markers. from 146 primers, 13 were chosen for amplification and 44 polymorphic bands were generated. the analysis of molecular variance (amova) indicated that the greatest portion of detected variability was due to differences between individuals within populations (75.47%). analysis of the genetic variability between pairs of populations presented higher estimates for the five pantaneiro populations with the arabian breed, while lowest estimates were presented by pairs formed among the pantaneiro populations with the mangalarga marchador. highest genic diversity was shown by the pantaneiro (0.3396), which also showed highest genetic distance with the arabian and lowest with mangalarga marchador breed. upgma dendrogram showed distinct differences between naturalized (pantaneiro and mangalarga marchador) and exotic (arabian and thoroughbred) breeds. in the dendrogram generated by upgma method, the similarity matrix generated by the jaccard coefficient showed distinction between the naturalised breeds, pantaneiro and mangalarga marchador, and the exotic breeds, árab and english thoroughbred. results suggest that the pantaneiro presents a higher genetic variability than the other studied breeds and has a close relationship with the mangalarga marchador.
