Acyrthosiphon pisum (Harris)
Common name: Pea aphid.
Geographical distribution: Cosmopolitan, occurring almost wherever members of the family Papilionaceae are grown. CIE Map #23, 1982 (revised).
Host plants: Mostly restricted to cultivated and wild members of the Papilionaceae.
Economic importance: The feeding of the pea aphid causes leaf curling, wilting and a general reduction in the yield of commercial legumes, especially alfalfa and clover. No sootymold damage is associated with this pest, because like other aphids with long antennae, its output of honeydew is meager.
Plant resistance: Some varieties of alfalfa and clover are resistant to this pest.
Biological control: The main natural enemies of the pea aphid are the aphidiid endoparasitoids Aphidius ervi Halliday and Aphidius urticae Halliday, and several entomopathogenic fungi; their individual contribution to the pest’s control is not known.
