“Recharging” pea aphids with pea enation mosaic virus

Virology, 1966
Abstract Pea aphids, Acyrthosiphon pisum (Harris) that are declining in their rate of transmission of the pea enation mosaic virus to sweetpea seedlings, Lathyrus odoratus L., can have their inoculative potential at least partially restored if given an additional acquisition access period on sweetpea plants infected with the virus. The probability of

Pea Aphid Control on Peas, 1977

Insecticide and Acaricide Tests, 1978
Abstract ‘Green Giant 531’ peas were planted April 29 at the University of Minnesota Rosemount Agricultural Experiment Station. Plots were 16 x 46 ft, randomized in complete blocks with 3 replications. The insecticides were applied June 21, 28, and July 6, in 60 gal water/acre at 176 psi, using a tractor-drawn boom sprayer.

Pea Aphid

2007
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

Melatonin and the pea aphid, Acyrthosiphon pisum

Journal of Insect Physiology, 1997
Pea aphids, Acyrthosiphon pisum, were fed on artificial diet containing various concentrations of melatonin. Under long-day conditions (16h light:8h dark) their progeny included males and virginoparous/oviparous (asexual/sexual) intermediate females, which normally occur only in short days or around critical night-length.

Studies on Pea Aphid Control*

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.

The aphid-bacterial symbiosis: a comparison between pea aphids and black bean aphids

Entomologia Experimentalis et Applicata, 1996
Over 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.

Phenology and prediction of pea aphid infestations on peas

International Journal of Pest Management, 1995
Abstract This study was designed to investigate the possibility of predicting the timing and level of infestation of the pea aphid, Acyrthosiphon pisum (Harris), a pest of economic importance in peas. The source of infestation is perennial legumes. We followed the life cycle of the pea aphid from egg overwintering sites in leys of alfalfa, Medicago ...
