Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

open access: yesInsect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Binding and toxicity of plant lectins to insects [PDF]

open access: yes, 2002
The toxicity of plant lectins to insects after oral ingestion was investigated by incorporating the proteins into insect diets. Bioassays carried out using an artificial diet system demonstrated that kidney bean (Phaseolus vulgaris) lectin (PHA) caused a

Insecticidal Potential of Citrus aurantium, Pimpinella anisum, and Cinnamomum verum Essential Oils against the Citrus Aphid Myzus persicae: A Comparative Study

open access: yesAfrican and Mediterranean Agricultural Journal - Al Awamia
In recent years, using essential oils as bio-insecticides has become a more widespread approach, responding directly to the growing demand for integrated pest management solutions.

Migration and the Spatial Dynamics of an Aphid, Myzus persicae

open access: yesThe Journal of Animal Ecology, 1977
During migration the spatial distribution of aphids must become diffuse because migration is dependent on the wind. Mortality during host finding is of the order of hundreds, possibly thousands to one and the subsequent capacity for reproduction, once a migrant is established, is correspondingly great, so that the numbers and distribution of aphids are

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

open access: yesInsect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Was Dan Janzen (1977) right about aphid clones being a "super-organism", i.e. a single "evolutionary individual"? : new insights from the use of molecular marker systems [PDF]

open access: yes, 2008
Dan Janzen proposed in a paper in 1977 (loc. cit.), that a clone of aphids and for that matter dandelions consists, respectively, of one large ‘super-organism’.

Chromosomal location of the amplified esterase genes conferring resistance to insecticides in Myzus persicae (Homoptera: Aphididae)

open access: yes, 1995
A genomic probe encompassing most of an esterase gene (E4) that is amplified in insecticide-resistant Myzus persicae was hybridized in situ to mitotic and meiotic chromosome preparations of aphid clones of known esterase type and resistance level ...

Prospects for the Use of Pongamia pinnata Oil-Based Products against the Green Peach Aphid Myzus persicae (Sulzer) (Hemiptera: Aphididae)

open access: yesPsyche: A Journal of Entomology, 2014
This study is devoted to an estimation of the action of preparations based on Pongamia pinnata oil on the life cycle (survival, fecundity) of green peach aphid Myzus persicae (Sulzer) (Hemiptera: Aphididae). The M.
