Remote Sensing in Ecology and Conservation, EarlyView.Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

Remote Sensing in Ecology and Conservation, EarlyView.Adélie penguins gather in colonies as standing or prone adults, individual chicks, and chick crèches. From drone images, we distinguish adults and chicks by their plumage, identify adult postures by body shape, and estimate the size of chick groups from the area they occupy. We map these groups and measure how closely penguins live together.

Rice Reoviruses in Insect Vectors
Annual Review of Phytopathology, 2016Rice reoviruses, transmitted by leafhopper or planthopper vectors in a persistent propagative manner, seriously threaten the stability of rice production in Asia. Understanding the mechanisms that enable viral transmission by insect vectors is a key to controlling these viral diseases.

RNA Interference in Insect Vectors for Plant Viruses
Viruses, 2016 Insects and other arthropods are the most important vectors of plant pathogens. The majority of plant pathogens are disseminated by arthropod vectors such as aphids, beetles, leafhoppers, planthoppers, thrips and whiteflies.

INSECT VECTORS OF PHYTOPLASMAS
Annual Review of Entomology, 2006▪ Abstract Plant diseases caused by, or associated with, phytoplasmas occur in hundreds of commercial and native plants, causing minor to extensive damage. Insect vectors, primarily leafhoppers, planthoppers, and psyllids, have been identified for relatively few phytoplasma diseases, limiting the capacity of managers to make informed decisions to ...

Localizing Viruses in Their Insect Vectors
Annual Review of Phytopathology, 2014The mechanisms and impacts of the transmission of plant viruses by insect vectors have been studied for more than a century. The virus route within the insect vector is amply documented in many cases, but the identity, the biochemical properties, and the structure of the actual molecules (or molecule domains) ensuring compatibility between them remain

Insect Biochemistry and Molecular Biology, 2004
The purpose of this study was to explore alternatives to insect-derived transposable elements as insect gene vectors with the intention of improving existing insect transgenesis methods. The mobility properties of the bacterial transposon, Tn5, were tested in mosquitoes using a transient transposable element mobility assay and by attempting to create ...

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.

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, 2009AbstractPalm 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 ...
