The Canadian Entomologist, 1987
The pea aphid, Acyrthosiphon pisum (Harris), is an important pest of alfalfa, Medicago sativa L., in Wisconsin because of its characteristic potential for exponential population growth (Hutchison and Hogg 1984, 1985) and the subsequent damage in both hay quality and quantity inflicted by high populations (Cuperus et al. 1982).

Entomologia Experimentalis et Applicata, 1997
Hymenopteran insects, including parasitoid wasps, usually have a haplo-diploid sex-determination system. This enables an ovipositing female to choose the sex of her egg by controlling sperm access to the egg (Flanders, 1956). The potential for sex ratio control makes hymenopteran insects ideal experimental organisms for testing sex ratio theory ...

Entomological Science, 2010
AbstractSince the invasion of Uroleucon nigrotuberculatum from North America we searched for parasitoids of this aphid on Solidago altissima in Japan to determine what species of native parasitoids attack the newly invasive aphid. We found three primary parasitoid species: Ephedrus plagiator and Praon yomenae (Braconidae, Aphidiinae) and Aphelinus ...

Abstract Improving the success rate of introduced biological control agents requires analysis of possible causes when a new natural enemy fails to thrive. For aphid parasitoids, the impact of hyperparasites is a potential obstacle to establishment and reproductive success.
