Explanation of Names
Aphis fabae Scopoli 1763
Wingless adults 1.8-3.1 mm
Body of wingless females ovoid, green-brown or black with wax pollination and big marginal tubercles on prothorax and on abdominal segments I and VII. Legs and antenna light yellow. Cornicles 2 times as long as the fingerlike tail; tarsi brown-black. Antennae two thirds as long as body. Head and thorax of winged female are black and shiny, and abdomen is black-green.
native to Europe, introduced to NA in late 1860s(1)
Recorded on almost 300 plant species. Primary (winter) hosts: Euonymus and Viburnum. Secondary (summer) hosts: sugar beet, beans, haricot beans, potatoes, sunflower, tomato and other cultivated and wild plants.
Life Cycle
Overwinters as eggs in the primary host. In the spring, after several generations of wingless forms (produced parthenogenetically), winged forms are produced that migrate to the secondary host. There are several wingless generations, then winged forms migrate back to primary host in the fall where males and females are produced and eggs are laid.

They can be a serious pest of many vegetables, specially beans and sugar beets.
9 out of 10 spp. of coccinellids, incl. the polyphagous Col. maculata, failed to complete larval development when fed on A. fabae. (Smith 1965)
