Population genetic structure and predominance of cyclical parthenogenesis in the bird cherry-oat aphid in England.

Genetic diversity is the determinant for pest species' success and vector competence. Understanding the ecological and evolutionary processes that determine the genetic diversity is fundamental to help identify the spatial scale at which pest populations are best managed. In the present study, we present the first comprehensive analysis of the genetic diversity and evolution of , a major pest of cereals and a main vector of the barley yellow dwarf virus (BYDV), in England.

Long-term phenological trends, species accumulation rates, aphid traits and climate: five decades of change in migrating aphids.

Aphids represent a significant challenge to food production. The Rothamsted Insect Survey (RIS) runs a network of 12·2-m suction-traps throughout the year to collect migrating aphids. In 2014, the RIS celebrated its 50th anniversary.
