Parasitism by Campoletis flavicincta on Spodoptera frugiperda in corn.

ABSTRACT: Parasitism by Campoletis flavicincta (Ashmead) (Hymenoptera: Ichneumonidae) on Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) and consequent reduction of production losses were evaluated on caged corn plants in the field. Treatments consisted of plots infested with 0 (control), 15 and 30 pairs of C. flavicincta with egg masses per cage and plot infested without cage and liberation of the parasitoid. Parasitoid release was done when S. frugiperda larvae were three-day-old. Fifty corn plants (40%) per plot were collected seven days after infestation and S. frugiperda larvae present were reared in glass cups on an artificial diet. Number of S. frugiperda larvae was reduced by C. flavicincta but mortality of the pest and parasitoid sex ratio in laboratory were similar among treatments. Total progeny and female production from collected larvae were similar among densities of released parasitoid. Parasitism rate was higher on 30 than on 15 pairs of C. flavicincta. Damage on corn plants at seven and 14 days after S. frugiperda infestation had similar grades at 0, 15 or 30 C. flavicincta pairs and higher values than the plots without cage. Damage by S. frugiperda was lower at 30 C. flavicincta pairs after 21 days of infestation. Final stand, stand reduction by plant death and corn productivity were similar among treatments RESUMO: O objetivo deste trabalho foi avaliar o potencial do parasitóide Campoletis flavicincta (Ashmead) (Hymenoptera: Ichneumonidae) no controle de Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) em plantas de milho protegidas por gaiolas no campo. Os tratamentos consistiram de parcelas infectadas com 0 (controle), 15 e 30 casais de C. flavicincta liberados por gaiola e parcela infestada, além de parcelas sem gaiola e sem liberação do parasitóide. C. flavicincta foi liberado quando as larvas de S. frugiperda estavam com três dias de idade. Em cada parcela, 40% das plantas foram colhidas sete dias após a infestação, e as larvas de S. frugiperda presentes foram transferidas para copos com dieta artificial. C. flavicincta reduziu o número de larvas, mas a mortalidade natural das larvas e a razão sexual do parasitóide emergido em laboratório foram semelhantes entre tratamentos. A produção de progênie e de progênie fêmea por C. flavicincta foi semelhante nas amostras de 15 e 30 casais, mas a taxa de parasitismo foi maior nas amostras de 30 casais do que nas de 15. Os danos às plantas por larvas de S. frugiperda, aos sete e 14 dias após a infestação, foram semelhantes entre as parcelas com 0, 15 ou 30 casais de C. flavicincta, maiores do que nas parcelas sem gaiola. Esses danos foram menores nas parcelas de 30 casais do parasitóide, após 21 dias da infestação. O estande final, redução no estande pela morte das plantas e a produtividade do milho foram semelhantes entre tratamentos

Multiple Epidermoid Cysts Arising from the Extratesticular Scrotal, Spermatic Cord and Perineal Area

An extratesticular scrotal epidermoid cyst is a relatively very rare condition, and an epidermoid cyst arising from the spermatic cord area is extremely rare. We report a case of multiple epidermoid cysts arising from the extratesticular scrotum, spermatic cord, and lower extremities. To our best knowledge, concomitant occurrence of these lesions has not been reported previously in the literature

Exploring the relationship between entrepreneurial behavior and teachers' job satisfaction

This exploratory study has two goals: exploring the relationship between entrepreneurial behavior and job satisfaction among teachers, and identifying the demographic characteristics associated with both variables. Using a snowball technique, a sample of 385 K-12 Brazilian teachers from public and private schools responded to the survey. Statistical analysis revealed a moderate correlation between entrepreneurial behavior and job satisfaction. Results also show that gender and educational level are associated with entrepreneurial behavior. The discussion includes theoretical and practical implications

SK-HEP cells and lentiviral vector for production of human recombinant factor VIII

Hemophilia A is caused by a deficiency in coagulation factor VIII. Recombinant factor VIII can be used as an alternative although it is unavailable for most patients. Here, we describe the production of a human recombinant B-domain-deleted FVIII (rBDDFVIII) by the human cell line SK-HEP-1, modified by a lentiviral vector rBDDFVIII was produced by recombinant SK-HEP cells (rSK-HEP) at 1.5-2.1 IU/10(6) in 24 h. The recombinant factor had increased in vitro stability when compared to commercial pdFVIII. The functionality of rBDDFVIII was shown by its biological activity and by tail-clip challenge in hemophilia A mice. The rSK-HEP cells grew in a scalable system and produced active rBDDFVIII, indicating that this platform production can be optimized to meet the commercial production scale needs.Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP

In this part, we provide some of the first scientific findings that we have already achieved with this network. We identified the diurnal and the seasonal natural variations of the H component. We provided the precise determination of sudden storm commencements and sudden impulse. We showed that the H amplitudes derived from the Embrace MagNet during intense magnetic storm are in very good agreement with the Dst index. We showed that it is possible to investigate the effects on the solar quiet ionospheric current systems as a response to the X-class solar flares occurring during daytime under magnetically quiet conditions. Plain Language Summary This manuscript is the second of a two-part paper and provides the reader with the first scientific findings from the new Embrace Magnetometer Network (Embrace MagNet), which is located in South America and is based on fluxgate magnetometer. The main purpose of this network is to fulfill the gap in magnetic measurement, which are suitable for space weather purpose. Details on the network description and its qualification are provided in the first paper.[Denardini, C. M.; Chen, S. S.; Resende, L. C. A.; Bilibio, A. V.; Padilha, A. L.; Alves, L.
