Capturing Insect Vectors of Phytoplasmas

2012
Insect vectors of phytoplasmas are limited to leafhoppers, planthoppers, and psyllids. While populations can be monitored by a number of passive techniques in the field, the capture of live insects is necessary for manipulation and study. A number of physical methods for capturing these insects already exist, but more innovative traps equipped with ...

Transmission of Grabloviruses by Insect Vectors

Among the three viruses of the genus Grablovirus in the plant virus family Geminiviridae, insect vector transmission is documented only for grapevine red blotch virus (GRBV), for which Spissistilus festinus (Hemiptera: Membracidae), the three-cornered alfalfa hopper, is identified as a vector. Transmission of GRBV by S.

Invasions by Insect Vectors of Human Disease

Annual Review of Entomology, 2002
▪ Abstract  Nonindigenous vectors that arrive, establish, and spread in new areas have fomented throughout recorded history epidemics of human diseases such as malaria, yellow fever, typhus, and plague. Although some vagile vectors, such as adults of black flies, biting midges, and tsetse flies, have dispersed into new habitats by flight or wind, human-

Insect pests and insect‐vectored diseases of palms

Australian Journal of Entomology, 2009
AbstractPalm production faces serious challenges ranging from diseases to damage by insect pests, all of which may reduce productivity by as much as 30%. A number of disorders of unknown aetiology but associated with insects are now recognised. Management practices that ensure the sustainability of palm production systems require a sound understanding ...

INSECT VECTORS OF POLIOMYELITIS

Journal of the American Medical Association, 1943
To the Editor:— In reading your editorial on "Insect Vectors of Poliomyelitis" in the August 28 issue ofThe JournalI was struck by this statement: "The dominant species in each group were green bottleflies and blowflies, the common housefly being present in small numbers in only two of the four positive specimens." The common housefly is such an ...

Immunity to eukaryotic parasites in vector insects

Current Opinion in Immunology, 1996
Mosquitoes and blackflies have been the focus of recent efforts to elucidate factors influencing the susceptibility of vector insects to metazoan and protozoan parasites of medical significance. Vector species exhibit variation in cellular and humoral immune responses, as highlighted by studies of melanotic encapsulation and components of the ...

Insects as vectors of foodborne pathogenic bacteria

Terrestrial Arthropod Reviews, 2011
AbstractFood safety is an important consideration worldwide. To maintain and improve our current knowledge of foodborne disease outbreaks, we must understand some of the more imminent issues related to food safety. A variety of agents are responsible for transmitting the estimated 76 million cases of illnesses caused by foodborne pathogens every year ...

Baculovirus vectors for expression in insect cells

Current Opinion in Biotechnology, 1996
Recombinant baculoviruses now represent a mature technology in which vector development, particularly for the control of expression level, has reached a plateau. However, other aspects of expression, such as the production of multiple proteins, improved product purification or maximizing protein processing, remain areas for novel vector and host cell ...

Vector insects and their control.

Ciba Foundation symposium, 1997
This paper emphasizes the huge influence that vector-transmitted disease has on humans using plague, epidemic typhus and nagana as examples. The continuing need for vector control in campaigns against insect-transmitted disease is shown by reference to current control programmes mounted against Chagas' disease, onchocerciasis, lymphatic filariasis and ...
