Ocorrência de Dinarmus basalis (Rondani) em Callosobruchus analis (F.) em soja armazenada em São Paulo, Brasil

Callosobruchus analis (F.) is considered an important pest in several countries in Africa, Asia and Oceania. It has been observed infesting seeds belonging to 15 Leguminosae genera, including peanut, bean, chickpea, pea, cowpea, and soybean. One of its main natural enemies is the parasitoid Dinarmus basalis (Rondani) (Hymenoptera: Pteromalidae), whose control efficiency has already been demonstrated in several studies. This paper records the occurrence of C. analis and its parasitoid, D. basalis, in stored soybean of the state of São Paulo, Brazil.Callosobruchus analis (F.) é uma praga de expressão econômica em diversos países da África, Ásia e Oceania. Já foi observado infestando sementes de espécies de leguminosas pertencentes a 15 gêneros, incluindo-se culturas como amendoim, grão-de-bico, feijão, ervilha, caupi e soja. Um de seus inimigos naturais mais importantes é o parasitóide Dinarmus basalis (Rondani) (Hymenoptera: Pteromalidae), cuja eficiência de controle já foi demonstrada em vários estudos. Neste trabalho registra-se a ocorrência de C. analis e de seu parasitóide, D. basalis, em grãos armazenados de soja no estado de São Paulo

Occurrence of Cephalonomia stephanoderis Betrem (Hymenoptera: Bethylidae) in coffee plantations of the Brazilian Amazonia

Adultos de Cephalonomia stephanoderis Betrem foram detectados em novembro de 2003 durante amostragem de frutos de Coffea canephora Pierre ex A. Froehner danificados por Hypothenemus hampei Ferrari (Coleoptera: Scolytidae) em Ouro Preto D'Oeste, RO (10º45'S e 62º15'W). De janeiro a julho de 2004, o parasitóide foi amostrada mensalmente em 200 frutos danificados por H. hampei. Provavelmente, C. stephanoderis exerça alguma pressão de parasitismo sobre a população da broca-do-café. A ocorrência do parasitóide em condições naturais aponta para outra alternativa de controle biológico de H. hampei em Rondônia. Este é o primeiro registro de C. stephanoderis em plantações de café na Amazônia brasileira.ABSTRACT Adults of Cephalonomia stephanoderis Betrem were detected (in November 2003) during the sampling of Coffea canephora Pierre ex A. Froehner berries damaged by Hypothenemus hampei Ferrari (Coleoptera: Scolytidae) in Ouro Preto D'Oeste – Rondônia, Brazil (10º45'S and 62º15'W). From January to July 2004, the parasitoid was monthly sampled in 200 berries damaged by H. hampei. Probably, C. stephanoderis can already exert some parasitism pressure at the coffee berry borer population. The occurrence of this parasitoid in natural conditions points out to another alternative for the biological control of the H. hampei in Rondônia. This is the first record of C. stephanoderis in coffee plantations of the Brazilian Amazonia

Occurrence of Dinarmus basalis parasitizing Callosobruchus maculatus in Vigna unguiculata in the semiarid region of the Rio Grande do Norte state, Brazil

Callosobruchus maculatus (Fab.) (Coleoptera: Chrysomelidae: Bruchinae) is the main pest of Vigna unguiculata (L.) Walp. during the grain storage period. This study aimed to report the occurrence of a natural enemy associated with C. maculatus in cowpea, in the semiarid region of the Rio Grande do Norte state, Brazil. For this, cowpea samples were collected and placed in closed plastic containers, where they remained until the emergence of adult insects. From the infested samples, adults of C. maculatus and of the Dinarmus basalis (Rondani) (Hymenoptera: Pteromalidae: Pteromalinae) parasitoid emerged. This is the first report of D. basalis parasitizing C. maculatus in the semiarid region of the Rio Grande do Norte state

Stabilization study of tetrameric kluyveromyces lactis β-galactosidase by immobilization on immobead: thermal, physico-chemical, textural and catalytic properties

We investigated the immobilization of a tetrameric Kluyveromyces lactis β-galactosidase (EC: 3.2.1.23) (KL-Gal) on Immobead 150 using different support modification strategies. Immobead support was modified using an acid solution of H2SO4:HNO3 (3:1) (Immobead-Ac) or 5 % (v/v) glutaraldehyde (Immobead-Glu). Its unmodified form (Immobead) was also tested. Immobilization yields and efficiencies were evaluated by testing protein loads from 10 to 200 mg.g-1 support. The thermal, physico-chemical, textural and catalytic properties of the supports (modified and unmodified) and their derivatives (Immobead-KL-Gal, Immobead-Ac-KL-Gal and Immobead-Glu-KL-Gal) were analyzed. The highest immobilization yields and efficiencies were achieved with a protein load of 100 mg.g-1 support. Surface and pore areas of the Immobead support were greatly decreased after modification. Michaelis constant of the immobilized β-galactosidase increased in the derivatives. Maximum velocity decreased approximately 2.8 times for Immobead-KL-Gal and Immobead-Glu-KL-Gal, and approximately 1.4 times for Immobead-Ac-KL-Gal. In batch processes, the three derivatives could be reused successfully at least 15 times, maintaining high residual enzymatic activity during the lactose hydrolysis (in both cheese whey and milk). The tetrameric K. lactis β-galactosidase immobilized on Immobead supports via the tested treatments was stabilized and is an alternative tool for lactose hydrolysis in the dairy industry

Babassu mesocarp (Orbignya pharelata Mart.) supplementation decreased markers of muscle damage, pain, and perceived exertion in trained young futsal athletes

Introduction and objective: This study aimed to evaluate the efficacy of babassu mesocarp flour (Orbignya pharelata Mart.) supplementation on muscle damage, pain, and effort perception in futsal athletes. Materials and methods: This is a randomized, single-blind, placebo-controlled trial. Ten recreational futsal athletes consumed water, maltodextrin, and babassu mesocarp flour supplement in three different occasions before the training protocol. There was a 5-day washout period between sessions. Afterwards, they underwent a plyometric training session and the futsal-specific intermittent shuttle protocol test (FISP). Blood samples were collected for creatine kinase (CK) analysis. Results: There was a significant increase in CK levels after the babassu supplementation of 11.25% (p=0.02, d=0.26), whereas the Maltodextrin had a non-significant increase of 29% (p=0.08). The reported muscle soreness was smaller after the ingestion of babassu for the jump and FISP tests (p=0.03 e p=0.01, respectively) compared to water intake. No significant difference was found between Babassu and Maltodextrin intake regarding muscle soreness. Conclusion: Babassu mesocarp flour supplementation reduced biomarkers of muscle damage and effort perceptions. However, there was a greater decrease in CK levels after maltodextrin intake compared to babassu mesocarp flour supplementation

Materiais e métodos: Este é um estudo randomizado, simples-cego, controlado por placebo. Dez atletas recreativos de futsal consumiram água, maltodextrina e suplemento de farinha de mesocarpo de babaçu em três ocasiões diferentes antes do protocolo de treinamento. Houve um período de washout de 5 dias entre as sessões. Em seguida, eles foram submetidos a uma sessão de treinamento pliométrico e ao teste de resistência específica intermitente de futsal (TREIF). Amostras de sangue foram coletadas para análise de creatina quinase (CK). Resultados: Houve aumento significativo dos níveis de CK após a suplementação de babaçu de 11,25% (p=0,02, d=0,26), enquanto a Maltodextrina teve aumento não significativo de 29% (p=0,08). A dor muscular relatada foi menor após a ingestão de babaçu para os testes de salto e TREIF (p=0,03 e p=0,01, respectivamente) em relação à ingestão de água. Não foi encontrada diferença significativa entre a ingestão de Babaçu e Maltodextrina considerando a dor muscular. Conclusão: A suplementação com farinha de mesocarpo de babaçu reduziu biomarcadores de dano muscular e percepção de esforço. No entanto, houve maior diminuição dos níveis de CK após a ingestão de maltodextrina em comparação com a suplementação com farinha de mesocarpo de babaçu
