1. Alterações nos parâmetros biológicos de Diatraea saccharalis (Lepidoptera: Crambidae) e Cotesia flavipes (Hymenoptera: Braconidae) causadas por Nosema sp. (Microsporidia: Nosematidae) / Alterations in biological parameters of Diatraea saccharalis (Lepidoptera: Crambidae) and Cotesia flavipes (Hymenoptera: Braconidae) caused by Nosema sp. (Microsporidia: Nosematidae)
O Filo Microsporidia é composto por parasitas intracelulares obrigatórios que infectam de invertebrados a mamíferos. Alguns gêneros de microsporídeos entomopatogênicos são de extrema importância, visto que diversos estudos epizootiológicos indicam tais agentes como detentores de um papel fundamental na regulação da densidade populacional de seus h

2. A urbanização da leishmaniose visceral associada à ocupação desordenada em ecossistemas costeiros no distrito de Monte Gordo/Camaçari-Bahia
In Brazil, the Visceral Leishmaniasis (VL) is a disease caused by a protozoan named Leishmania chagasi, typical from tropical areas under favourable environmental conditions to the transmitting agent reproduction, a insect, phlebotomine Lutzomyia longipalpis. Its a search that covers Monte Gordo District, Camaçari County, Northern Coast of Bahia - which aim

3. Estudo taxonÃmico e armazenamento de nematÃides entomopatogÃnicos (Rhabditida: Steinernematidae, Heterorhabditidae) / Taxonomic studies and storage of entomopathogenic nematodes (Rhabditida: Steinernematidae, Heterorhabditidae)
Os nematÃides entomopatogÃnicos estÃo sendo cada vez mais estudados; no entanto, apresentam baixa viabilidade em condiÃÃes de laboratÃrio. Assim, este trabalho teve como objetivos o estudo taxonÃmico de uma nova espÃcie de nematÃide entomopatogÃnico isolado na regiÃo amazÃnica e o estudo das melhores condiÃÃes para armazenamento, visando uso em

4. Isolamento, identificação, síntese e avaliação de campo do feromônio sexual do minador-dos-citros, Phyllocnistis citrella Stainton, 1856 (Lepidoptera: Gracillariidae) / Isolation, identification, synthesis and field evaluation of the sex pheromone from the citrus leafminer, Phyllocnistis citrella Stainton, 1856 (Lepidoptera: Gracillariidae)
The objectives of this work were to isolate, identify, and synthesize the sex pheromone of Phyllocnistis citrella Stainton, 1856 (Lepidoptera: Gracillariidae), as well as to evaluate its efficiency in field conditions, to rationalize the control of this pest within a Citrus Integrated Pest Management scope. The research was developed at the Insect of Biology

5. Efeito de produtos vegetais na qualidade fisiologica e sanitaria de sementes de labe-labe (Dolichos lablab L.) na armazenagem
The lablab bean (Dolichos lablab L.) is a useful annual or biennial fabacea of ample potencial use in agriculture as forage, hay, fodder, ensilage, green manure and even as human feed in certain countries. In the State of São Paulo (Brazil), cv. Rongai is the one most often found commercial/y. Its seeds, however, are frequently attacked by insects, special/

6. Methods for Maintaining Insect Cell Cultures
Insect cell cultures are now commonly used in insect physiology, developmental biology, pathology, and molecular biology. As the field has advanced from methods development to a standard procedure, so has the diversity of scientists using the technique. This paper describes methods that are effective for maintaining various insect cell lines. The procedures

7. The insect tracheal system: a conduit for the systemic spread of Autographa californica M nuclear polyhedrosis virus.
Baculoviruses establish systemic infections within susceptible insect hosts, even though host tissues are surrounded by basal laminae, extracellular matrices that exclude particles smaller than these viruses. Using a recombinant Autographa californica M nuclear polyhedrosis virus containing a lacZ reporter gene under the control of a constitutive promoter, w

8. Habitat Association in Two Genetic Groups of the Insect-Pathogenic Fungus Metarhizium anisopliae: Uncovering Cryptic Species?
Strains of insect-pathogenic fungi with high virulence toward certain pest insects have great potential for commercial biological control applications. Identifying such strains has been a central theme in using fungi for biological control. This theme is supported by a persistent paradigm in insect pathology which suggests that the host insect is the predomi

9. The Bacillus thuringiensis vegetative insecticidal protein Vip3A lyses midgut epithelium cells of susceptible insects.
The Vip3A protein is a member of a newly discovered class of vegetative insecticidal proteins with activity against a broad spectrum of lepidopteran insects. Histopathological observations indicate that Vip3A ingestion by susceptible insects such as the black cutworm (Agrotis ipsilon) and fall armyworm (Spodoptera frugiperda) causes gut paralysis at concentr

10. Pathology and Development of the Grasshopper Inclusion Body Virus in Melanoplus sanguinipes
Grasshoppers, Melanoplus sanguinipes (F.), infected with the grasshopper inclusion body virus (GIBV) showed a general torpor, took longer to develop, and had abnormally high rates of mortality. Infection was found only in the fat body, and developing viruses and inclusion bodies were observed in the nuclei and cytoplasm of infected cells. Although the size o

11. Metarrhizium anisopliae as a Cause of Sinusitis in Immunocompetent Hosts
Metarrhizium anisopliae is a common pathogen of insects and has even been used to control insect populations. It is rarely isolated from human or animal sources, but recently, there have been three reported cases of disease, two in humans and one in a cat. We present our experience with five isolates from human sources, including two that were the apparent c

12. Pathology and Epizootiology of Entomophaga maimaiga Infections in Forest Lepidoptera
The insect-pathogenic fungal pathogen Entomophaga maimaiga is endemic to northeastern Asia and was first found in North America in 1989. Due to repeated epizootics and spread within populations of the major forest defoliator in northeastern North America, the gypsy moth (Lymantria dispar), this pathogen has gained much notoriety. Although this pathogen was p
