2. Cloning and purification of the first termicin-like peptide from the cockroach Eupolyphaga sinensis
Abstract Background Termicin is an antimicrobial peptide with six cysteines forming three disulfide bridges that was firstly isolated from the salivary glands and hemocytes of the termite Pseudacanthotermes spiniger. In contrast to many broad-spectrum antimicrobial peptides, termicin is most active against filamentous fungi. Although more than one hundred

3. Molecular cloning and functional analysis of the fatty acid-binding protein (Sp-FABP) gene in the mud crab (Scylla paramamosain)
Intracellular fatty acid-binding proteins (FABPs) are multifunctional cytosolic lipid-binding proteins found in vertebrates and invertebrates. In this work, we used RACE to obtain a full-length cDNA of Sp-FABP from the mud crab Scylla paramamosain. The open reading frame of the full length cDNA (886 bp) encoded a 136 amino acid polypeptide that showed high h

4. Efeito da resistência de Spodoptera frugiperda (J.E.Smith, 1797) (Lepidoptera: Noctuidae) a lambda-cyhalothrin na interação com o milho geneticamente modificado (MON810) e na resposta imunológica ao parasitismo por Campoletis af / Effect of resistance of Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) to lambda-cyhalothrin on the interaction with genetically modified maize (MON810) and the immune response to parasitization by Campoletis aff. flavicincta (Hymenoptera: Ichneumonidae)
Fitness costs of insect resistance to insecticides can be exploited by integrating other pest control strategies in Integrated Pest Management (IPM) programs. The objective of this research was to evaluate the existence of fitness costs associated with the resistance of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) to the pyrethroid insecticid

5. Mutagênese ambiental: estabelecimento de valores de referência para manguezais da Baía de Ilha Grande / Environmental mutagenesis: establishment of reference valves for mangroves of Ilha Grande Bay
Environmental studies have shown that substances generated by anthropogenic processes can cause adverse effects by interfering with the ecosystem natural balance. Mangroves perform essential functions in biological cycles and are Permanent Protection Area in Brazil. Unfortunately, they are being degraded above its support limit, leading to a reduction of the

6. Respostas imunológicas e mecânicas em população suscetível e resistente Plutella xylostella (L.) (Lepidoptera : Plutellidae) frente a formulações comerciais à base de Bacillus thuringiensis Berliner / Immunologicals and mecanicals responses in susceptible and resistant population of Plutella xylostella (L.) (Lepidoptera : Plutellidae) stand up to commercials formulations of Bacillus thuringiensis Berliner
The resistance of Plutella xylostella (L.) (Lepidoptera: Plutellidae) has been attributed to many mechanisms as alterations in cell membrane receptors on midgut and the immune response to Bacillus thuringiensis Berliner toxin. The research tested the possibility that after expositions to Bt formulations, insects from a susceptible population (SP) and a resis

7. Interaction of Metarhizium anisopliae (Metsch), Beauveria bassiana (Bals.) and granulovirus, the main pathogens of Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Crambidae) / Interação de Metarhizium anisopliae (Metsch.), Beauveria bassiana (Bals.) e vírus da granulose, principais patógenos de Diatraea saccharalis (Fabr., 1794) (Lepidoptera: Crambidae)
The sugarcane borer, Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) is naturally infected by various pathogens, the most important are Metarhizium anisopliae (Metsch) (Ascomycota: Clavicipitaceae), Beauveria bassiana (Bals.) (Ascomycota: Cordycipitaceae) and granulovirus. These microorganisms may coinfect the same host under field conditions

8. Pathogenicity of the fungi genus Isaria (Persoon) on Coptotermes gestroi (Wasmann) (Isoptera : Rhinotermitidae) and immunologic aspects / Patogenicidade de fungos do gênero Isaria (Persoon) sobre Coptotermes gestroi (Wasmann) (Isoptera : Rhinotermitidae) e aspectos imunológicos
The termite Coptotermes gestroi (Wasmann) is an urban and agricultural pest that has been established in many areas of the world. The use of entomopathogenic fungi is an option to minimize the economic loss caused by this termite. It is known, however, that physiological disorders caused by a pathogen trigger defence reactions of the insects, such as humoral

9. Susceptibility of Rosa Shrimp Farfantepenaeus subtilis (Pérez-Farfante, 1967) to Infectious myonecrosis virus (IMNV) / Susceptibilidade do Camarão Rosa Farfantepenaeus subtilis (Pérez-Farfante, 1967) ao Vírus da Mionecrose Infecciosa (IMNV)
Viral diseases are causing great damage in shrimp farming. With the IMN virus emergence in Northeastern Brazil in 2002, the shrimp producers faced an unknown disease that caused significant losses for the industry. Thus, a better knowledge about this disease and the investigation of how other species of shrimp are affected by the IMN virus will be an importa

10. Sistema imune inato em Melípona scutellaris (Hymenoptera, Apidae, Meliponini)
CAPITULO II: Infecção em insetos estimula uma resposta defensiva complexa. O reconhecimento de patógenos pode ser realizado pelos hemócitos ou proteínas que se ligam especificamente em microorganismos com padrões moleculares específicos, os chamados (PAMPs). Diferentes células da hemolinfa cooperam na resposta imune. Os hemócitos reconhecem os pató

11. Histophysiology of the food channel and hemocytes of Spodoptera frugiperda (J.E. Smith) (Lepidoptera : Noctuidae) treated with neem (Azadirachta indica A.Juss) / Histofisiologia do canal alimentar e hemócitos de Spodoptera frugiperda (J.E. Smith) (Lepidoptera : Noctuidae) tratadas com Nim (Azadirachta indica A.Juss)
Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is the main pest of corn crops. The control of S. frugiperda requires various insecticide applications that might result on selection of resistant populations and environmental contamination. A promising alternative toward the control of this pest is the use of vegetal insecticides such as neem, Aza

12. The role of hemocytes on the immunity of the spider Acanthoscurria gomesiana. / Envolvimento dos hemócitos na resposta imune da aranha caranguejeira Acanthoscurria gomesiana.
Os invertebrados impedem o estabelecimento de uma infecção através de uma resposta imune eficiente. Esta resposta envolve reações celulares e humorais. Existem poucos trabalhos sobre a imunidade das aranhas. O principal objetivo deste estudo foi verificar o papel dos hemócitos e dos peptídeos antimicrobianos na resposta imune da aranha Acanthoscurria
