Aphids have long been of interest because of their complex life cycles, environmentally induced morphologies, and importance to agriculture. However, only recently has the resulting wealth of ecological and population genetic data begun to be supplemented by genomic and genetic mapping approaches. In 2004, the International Aphid Genomics Consortium, a

Insect and disease pests are prevalent in both residential and commercial food production settings, meaning that a large number of Idahoans contend with them each year. Part of an integrated pest management (IPM) series, this colorfully illustrated bulletin helps homeowners and growers alike to identify pea aphids and to learn the IPM options available

Journal of Economic Entomology, 1939
In order to determine if annual applications of insecticide for control of the pea aphid, Illinoia pisi (Kltb.), on the Eastern Shore of Maryland would show a profit, a 5-year experiment was begun in 1938 at the Ridgely Substation. In this experiment treatments for aphid control are to be made each year regardless of the extent of the infestation.

Modulation of Aphid Alarm Pheromone Emission of Pea Aphid Prey by Predators
Journal of Chemical Ecology, 2013Recent studies on animal alarm signaling have shown that alarm calls generally are not uniform, but may vary depending on the type and intensity of threat. While alarm call variability has been studied intensively in birds and mammals, little is known about such variation in insects.

Pea aphids feeding from birth to maturity on pea plants (Pisum sativum) exposed to SO(2) concentrations of 50 nl litre(-1) or 80 nl litre(-1) showed a significant 19% increase in the rate of nymph production during the reproductive period, compared to control aphids feeding on plants in charcoal-filtered air.

The aphidâbacterial symbiosis: a comparison between pea aphids and black bean aphids
Entomologia Experimentalis et Applicata, 1996Over the years, a variety of aphid species have been used to study the symbiosis with the bacteria Budinera (e.g. Ehrhardt, 1969; Mittler, 1971; Hinde, 1971; Campbell & Nes, 1983). Recent research, however, has focused almost exclusively on one species, the pea aphid Acyrthosiphon pisum.

Cannibalism in the pea aphid,Acyrthosiphon pisum
Insect Science, 2013AbstractPrevious observations of cannibalism have been made in the aphidAcyrthosiphon pisum(L.): this article seeks to quantify factors contributing to such behaviors. We observed and quantified the responses of a number of clones and life stages to varying levels of starvation, in the form of increasingly desiccatedVica fabaL. plants (receiving 50, 25,

Fate of pea enation mosaic virus in PEMV-injected pea aphids
Virology, 1975Abstract Ultrathin sections were prepared for electron microscopy from excised organs and tissues of viruliferous pea aphids, Acyrthosiphon pisum (Harris). Aphids were rendered viruliferous by injecting pea enation mosaic virus (PEMV) directly into the hemocoele.

Pea Aphid: Rearing on a Chemically Defined Diet
Science, 1963Pea aphids, Acyrthosiphon pisum (Harr.), reared for two successive generations on a diet made of 23 amino acids and amides, 11 water-soluble vitamins, 35 percent sucrose, salts, and cholesterol, remained apterous. They grew and developed during the first generation almost as well as those grown on pea plants, with ...

The Pea Aphid as an Alfalfa Pest in California
Journal of Economic Entomology, 1926The recent outbreaks of pea aphid, Illinoia pisi Kalt., in southern California have followed mild winters with low rainfall, which allowed the survival of many viviparous females and their rapid multiplication with the advent of spring. The first growth of alfalfa in infested fields was destroyed, the second growth weakened, and weeds enabled to grow ...
