Asparagus aphid

[R]Description
Adult: 1.5 mm long, elongate, narrow, bluish-green and covered with a waxy powder, thus taking on a greyish coloration; antennae very short (1/4 of body length); cauda long; siphunculi very short with a nipple-like pore (*) .

[R]Biology
Typically a pest of asparagus, this aphid originates from the eastern Mediterranean region and east of Europe (Ukraine, Southern Russia, Hungary) and was first seen in France in 1987 and 1988.

[R]Life Cycle
An autoecious and holocyclic species overwintering in the egg stage, eggs being laid in the autumn on stems or at their base, at ground level.

[R]Damage
Affected stems are weakened (toxaemia), develop imperfectly, become stunted and broom-like, plants growing in the shape of a bush. This results in shorter stems the following year. The turions become smaller and their commercial value is partly reduced. The stems become very susceptible to contamination by Fusarium moniliforme, which causes affected plants to die rapidly; these must then be pulled up.
