1. Entomopathogenic fungi and their potential for the management of Aedes aegypti (Diptera: Culicidae) in the Americas
Classical biological control has been used extensively for the management of exotic weeds and agricultural pests, but never for alien insect vectors of medical importance. This simple but elegant control strategy involves the introduction of coevolved natural enemies from the centre of origin of the target alien species. Aedes aegypti - the primary vector of

2. Detection of Ehrlichia canis in domestic cats in the central-western region of Brazil
Ehrlichiosis is a worldwide distributed disease caused by different bacteria of the Ehrlichia genus that are transmitted by arthropod vectors. Its occurrence in dogs is considered endemic in several regions of Brazil. Regarding cats, however, few studies have been done and, consequently, there is not enough data available. In order to detect Ehrlichia spp. i

3. Behavioural biology of Chagas disease vectors
Many arthropod species have adopted vertebrate blood as their main food source. Blood is rich in nutrients and, except for the presence of parasites, sterile. However, this food source is not freely available, nor is obtaining it devoid of risk. It circulates inside vessels hidden underneath the skin of mobile hosts that are able to defend themselves and eve

4. Análise do efeito causado pelos genes quitinase e catepsina dos baculovírus CfDefNPV e AcMNPV inseridos no genoma do Anticarsia gemmatalis multiple nucleopolyhedrovirus
Baculoviruses are double-stranded DNA viruses, arthropod-specific that have been mainly used as biological-control agents of insect pests and as heterologous gene expression vectors. The use of the Anticarsia gemmatalis multiple nucleopolyhedrovirus (AgMNPV) in Brazil, for the control of the velvetbean caterpillar is the most successful example of a virus us

5. Comparison between precipitin and ELISA tests in the bloodmeal detection of Aedes aegypti (Linnaeus) and Aedes fluviatilis (Lutz) mosquitoes experimentally fed on feline, canine and human hosts
The identification of arthropod bloodmeals is important in many epidemiological studies, as, the understanding of the life cycle of vectors and the patogens they transmit, as well as helping to define arthropods' control strategies. The precipitin test has been used for decades, but ELISA is slowly becoming more popular. To compare the two tests for sensitiv

6. Sloth biology: an update on their physiological ecology, behavior and role as vectors of arthropods and arboviruses
This is a review of the research undertaken since 1971 on the behavior and physiological ecology of sloths. The animals exhibit numerous fascinating features. Sloth hair is extremely specialized for a wet tropical environment and contains symbiotic algae. Activity shows circadian and seasonal variation. Nutrients derived from the food, particularly in Bradyp

7. Epidemiological importance of Aedes albopictus in Americas / Importância epidemiológica do Aedes Albopictus nas Américas
No presente trabalho procura-se caracterizar biológica e ecologicamente o Aedes albopictus (Skuse) (Diptera: Culicidae) no seu mais recente ambiente geográfico, isto é, nas Américas. São descritos aspectos relacionados com a chegada e dispersão da espécie no Continente Americano. Paralelamente, são discutidos aspectos relativos ao comportamento, biol

8. Mechanisms of Arthropod Transmission of Plant and Animal Viruses
A majority of the plant-infecting viruses and many of the animal-infecting viruses are dependent upon arthropod vectors for transmission between hosts and/or as alternative hosts. The viruses have evolved specific associations with their vectors, and we are beginning to understand the underlying mechanisms that regulate the virus transmission process. A majo

9. Processing and microfiltration of mosquitoes for malaria antigen detection in a rapid dot immunobinding assay.
Data on a technique for the detection of antigen from arthropod vectors in a dot immunobinding assay are presented. In this system, antigen present in the vector was first solubilized in sodium dodecyl sulfate. The homogenate from this process was microfiltered through a two-membrane sandwich; target antigen molecules passed through the first membrane and we

10. Genetic variation in arthropod vectors of disease-causing organisms: obstacles and opportunities.
An overview of the genetic variation in arthropods that transmit pathogens to vertebrates is presented, emphasizing the genetics of vector-pathogen relationships and the biochemical genetics of vectors. Vector-pathogen interactions are reviewed briefly as a prelude to a discussion of the genetics of susceptibility and refractoriness in vectors. Susceptibilit

11. Molecular Strategies for Interrupting Arthropod-Borne Virus Transmission by Mosquitoes
Arthropod-borne virus (arbovirus) infections cause a number of emerging and resurgent human and veterinary infectious diseases. Traditional means of controlling arbovirus diseases include vaccination of susceptible vertebrates and mosquito control, but in many cases these have been unavailable or ineffective, and so novel strategies for disease control are n

12. Behaviour of filariae: morphological and anatomical signatures of their life style within the arthropod and vertebrate hosts
This paper attempts to pinpoint the most original morphological anatomical features of the biology of filariae per se and those which are or could be important for triggering regulatory processes in the arthropod vector and uncontrolled pathogenic processes in the vertebrate hosts. The following stages are considered: the motile egg or newly-hatched larva, t
