A peptide that binds the pea aphid gut impedes entry of Pea enation mosaic virus into the aphid hemocoel

Virology, 2010
Development of ways to block virus transmission by aphids could lead to novel and broad-spectrum means of controlling plant viruses. Viruses in the Luteoviridae enhanced are obligately transmitted by aphids in a persistent manner that requires virion ...

Responses to aphid sex pheromones by the pea aphid parasitoids Aphidius ervi and Aphidius eadyi

Entomologia Experimentalis Et Applicata, 1999
Aphidius ervi and Aphidius eadyi, two parasitoids of the pea aphid Acyrthosiphon pisum, were attracted to components of the aphid sex pheromone in laboratory bioassays.

“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

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.

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.

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 ...
