Barley yellow dwarf epidemiology [PDF]

, 2006
Barley yellow dwarf (BYD) disease is induced by viruses that are vectored by aphids. The viruses infect grasses and cause severe damage on oats, barley and wheat worldwide.

Pandora neoaphidis transmission and aphid foraging behaviour

, 2005
Pandora neoaphidis is an aphid-specific entomopathogen that produces infective conidia. As aphid movement increases, so does the likelihood of contact with conidia.

Replication-independent change in the frequencies of distinct genome segments of a multipartite virus during its transit within aphid vectors

Microbiology Spectrum
Multipartite viruses exhibit a fragmented genome composed of several nucleic acid segments individually packaged in distinct viral particles. The genome of all species of the genus Nanovirus holds eight segments, which accumulate at a very specific and ...

Sub-lethal effect of combination of Metarhizium anisopliae and imidacloprid on life table of Myzus persicae (Hem.: Aphididae)

Journal of Crop Protection, 2015
The sub-lethal effect of Metarhizium anisopliae and imidacloprid as well as combination of the two control agents was examined on life table parameters of Myzus persicae on different cultivars of canola under laboratory condition at 25 ± 1 ºC, 85% RH and

Influence of the aphid pathogen Pandora neoaphidis on the foraging behaviour of the aphid parasitoid Aphidius ervi

, 2005
1. The parasitoid Aphidius ervi and the entomopathogenic fungus Pandora neoaphidis both require successful invasion of an aphid host to complete their life cycle. A shorter developmental period allows P. neoaphidis to out-compete A. ervi.

Nutrition Rather Than Phytohormone-Dependent Defense of Host Plant Mediates the Different Response of Red- and Green-Morph Pea Aphids to Nitrogen Fertilization

Agronomy
Nitrogen fertilization is widely known to affect plant metabolism, which subsequently influences phytophagous insects through a bottom-up effect. The interplay between plants and insects is often overlooked in studies examining the effects of nitrogen ...

The effects of nitrogen and fungicide on cereal aphid population development and the consequences for the aphid-yield relationship in winter wheat

, 1991
In a field trial, done over two seasons, nitrogen and fungicide inputs to winter wheat were varied to obtain a range of yields to study the effects on aphid population development and the aphid-yield loss relationship.

AgoArmet and AgoC002: key effector proteins in cotton aphids host adaptation

Frontiers in Plant Science
Aphids are insects that feed on phloem and introduce effector proteins into plant cells through saliva. These effector proteins are key in regulating host plant defense and enhancing aphid host adaptation.
