How to protect the cucumber crop from the outbreak of Aphid

Nymphs and adults both insects are soft-bodied, pear-shaped, and blackish in color.
Large colonies of nymphs and adults are found on tender twigs and shoots as well as on the ventral leaf surface sucking the vital sap from the tissues.
The affected parts turn yellow, get curled, wrinkled, and deformed in shape and ultimately dry and die away.
Fruit size and quality is also reduced.
The aphids also exude copious quantities of honeydew on which sooty mold develops which in turn hinders the photosynthetic activity of the vines, resulting in stunted growth.
