Modification of arthropod vector competence via symbiotic bacteria

Parasitology Today, 1993
Some of the world's most devastating diseases are transmitted by arthropod vectors. Attempts to control these arthropods are currently being challenged by the widespread appearance of insecticide resistance. It is therefore desirable to develop alternative strategies to complement existing methods of vector control. In this review, Charles Beard, Scott

Arthropod Vectors as Reservoirs of Microbial Disease Agents

Annual Review of Entomology, 1961
The subject of arthropod vectors as reservoirs of agents of animal diseases is difficult to review because of divergent viewpoints of the definition of a "reservoir." Some investigators would reserve this term for vertebrate hosts and the term "vector" for intermediate hosts (141).

Evolution of Arthropod Disease Vectors

2003
Abstract Fossils resembling arthropods first appeared during the late Proterozoic about 600 to 540 million years ago. Today the phylum Arthropoda contains∼80% of all extant metazoan animal species, and arthropods have come to occupy virtually every marine, freshwater, terrestrial, and aerial habitat on earth.

Haematophagous Arthropods as Vectors of Diseases

2010
The first terrestrial forms of arthropods appeared in the Palaeozoic, at the turn of the Silurian and Devonian ages some 400 million years ago. Today, arthropods form about 85% of all known animal species. They are characterized by segmentation of the body and limbs, reticulated paired appendages (antennae etc.), exoskeleton formed mainly of chitin ...

Decoding arthropod vector immunology through bona fide pathogens

Trends in Parasitology
The interrelationship between the microbiota, metabolism, and the arthropod immune system has evolved to maintain physiological equilibrium. Arthropods rely on this delicate balance when encountering fitness challenges. The understanding of life history traits in arthropod vectors has been hampered by technological difficulties compounded by limited ...

Avermectins in arthropod vector management — prospects and pitfalls

Parasitology Today, 1993
The proven impact of avermectins against a wide variety of arthropod vectors suggests that this new family of compounds holds promise in reducing the incidence of vector-borne disease. Experimentally, decreased survival and abundance of various vector species indicate that certain vector populations may be so manipulated. In addition, sublethal effects

Arthropod promoters for genetic control of disease vectors

Trends in Parasitology
Vector-borne diseases (VBDs) impose devastating effects on human health and a heavy financial burden. Malaria, Lyme disease, and dengue fever are just a few examples of VBDs that cause severe illnesses. The current strategies to control VBDs consist mainly of environmental modification and chemical use, and to a small extent, genetic approaches.

Calreticulin in Vector Arthropods—The Secreted Calreticulin

1996
One of the most unusual places calreticulin has been found is the saliva of ticks.1 Most calreticulins are located intracellularly. Our work objective was to characterize and clone salivary secretions that induce host immunity to tick feeding.2,3 Host immune response to tick feeding was demonstrated in domesticated animals as early as 1918.4 Trager5 ...
