Book Description
This series explores how vectors (carriers of disease agents, such as insects) acquire, carry and subsequently transmit pathogens to hosts. It covers the spectrum of vectors, including carriers of plant pathogens as well as medically related pathogens. The Chapters in Volume 7 include: 1. "K. Gibb, J.W. Randles: " Transmission of velvet tobacco mottle virus and related viruses by the mirid Cyrto- peltis nicotianae. 2. "N. Carter, R. Harrington: " Factors influencing aphid population dynamics and behavior and the consequences for virus spread. 3. "R.H. Bagnall: " Cyclic epidemics of aphid-borne potato viruses in Northern seed-potato-growing areas. 4. "C.J. Andrews, R.C. Sinha: " Interactions between barley yellow dwarf virus infection and winter-stress tolerance in cereals. 5. "J.R. DeLoach, G. " "Spates: " Artificial diets for blood feeding insects: a review. 6. "I. Maudlin: " Transmission of African trypanosomiasis: interactions among Tsetse immune system, symbionts, and parasites. 7. "C. Chastel, I. Humphery-Smith: " Mosquito spiroplasmas. The first four chapters cover topics in plant virus transmission by insects. The final three chapters focus on human and animal disease associations with bollid-feeding flies.

Book Description
Volume 10 of Advances in Disease Vector Research consists of seven chapters on vectors that affect human or animal health and six chapters on plant pathogens and their vectors. In Chapter 1, Yasuo Chinzei and DeMar Taylor discuss hormonal regulation of vitellogenesis in ticks. Many blood sucking insects and ticks transmit pathogens by engorgement, which induces vitellogenesis and oviposition in adult animals. To investigate the pathogen transmission mechanism in vector animals, information on the host physiological and endocrinological conditions after engorgement is useful and important because pathogen development or proliferation occurs in the vector hosts at the same time as the host reproduction. Chinzei and Taylor have shown that in ticks, juvenile hormone (JH) is not involved in the endocrinological processes inducing vitellogenin biosynthesis. Synganglion (tick brain) factor(s) (vitellogenesis inducing factor, VIF) is more important to initiate vitellogenesis after engorgement, and ecdysteroids are also related to induction of vitellogenin synthesis. In their chapter, based mainly on their own experimental data, the authors discuss the characterization of main yolk protein, vitellogenin (Vg) , biosynthesis and processing in the fat body, and hormonal regulation of Vg synthesis in tick systems, including ixodid and argasid ticks.

Book Description
Entomology, plant pathology and virology are a few of the disciplines covered by this well-reviewed series. It also covers the spectrum of vectors from mosquitos and leafhoppers to nematodes, and pathogens from viruses to mycoplasmas to protozoa. Articles deal with the emerging science of vector ecology, and consider both biotic and abiotic environmental influences on disease transmission. As a form to present current thinking in this field, the series is an important resource for researchers and students involved in understanding and overcoming the many vector-borne diseases of plants, animals, and humans.

Book Description
Volume 9 in this series consists of four chapters on vectors that affect human or animal health and six chapters on plant pathogens and their vectors. In Chapter 1, Alex S. Raikhel discusses vitellogenesis in mosquitoes: the cornerstone of the reproductive cycle involving massive production of yolk precursors by the fat body and their accumulation in developing oocytes. In anautogeneous mosquitoes, vitellogenesis is dependent on the availability of a blood meal and, as a consequence, is linked to transmission of pathogens. Therefore, elucidation of mechanisms governing the mosquito vitellogenesis is critical for the successful development of novel strategies in vector and disease management. Previous reviews on mosquito vitellogenesis have dealt predominantly with hormonal control. The goal of this review, however, is to summarize significant progress which has been achieved in understanding mosquito vitellogenesis at the cellular, biochemical and molecular levels. It is with these disciplines that we expect to fully understand the mechanisms governing this key process in mosquito reproduction.

Book Description
Vector transmission of pathogens affecting human, animal, and plant health continues to plague mankind both in industrialized and Third World coun tries. The diseases caused by these pathogens cost billions of dollars an nually in medical expenses and lost productivity. Some cause widespread of food-and fiber-producing plants and animals, whereas others destruction present direct and immediate threats to human life and further development in Third World countries. During the past 15 years or so, we have witnessed an explosive increase in interest in how vectors acquire, carry, and subsequently inoculate dis ease agents to human, animal, and plant hosts. This interest transcends the boundaries of anyone discipline and involves researchers from such varied fields as human and veterinary medicine, entomology, plant pa thology, virology, physiology, microbiology, parasitology, biochemistry, molecular biology, genetic engineering, ultrastructure, biophysics, bio systematics, biogeography, ecology, behavioral sciences, and others. Ac companying and perhaps generating this renewed interest is the realization that fundamental knowledge of pathogen-vector-host interrelationships is a first and necessary step in our quest for efficient, safe methods of disease control.

Book Description
I think the reader will agree that we have attained a good balance in Volume 6 between human-or animal-host and plant-host-related topics from outstanding research scientists. In Chapter 1, Frank Collins, Susan Paskewitz, and Victoria Finnerty explore the potential of recombinant DNA technology to distinguish indi vidual species and to establish phylogenetic relationships among member species in the Anopheles gambiae species complex, which includes the principal malaria vectors. Currently, relatively little is known about these morphologically identical species that are sympatric over most of their range but are not always equally involved in malaria transmission. With respect to individual species identification, the researchers have thus far described two DNA fragments, derived from the ribosomal DNA interge nic spacer region, that reliably distinguish five species in the complex by means of an RFLP visualized on a Southern blot. They have also described other species-specific fragments derived from a ribosomal DNA intron that could form the basis for a rapid dot blot assay. With respect to the phylogenetic relationships among member species in the complex, Collins, Paskewitz, and Finnerty focus on a comparison at the level of restriction site mapping and Southern analysis of the rDNA intergenic spacer regions. As expected, the two spacer regions near the coding region junctions are well conserved among the species, whereas the central regions tend to be highly variable among member species in the complex.
