Green lacewing for melon aphid

Chrysoperla carnea · green lacewing larvae
Against melon aphid

UC IPM lists lacewing larvae among melon aphid's predators in cucurbits, and green lacewings among the important aphid predators in greenhouse ornamentals. Melon aphid feeds on leaf undersides and growing tips, so release larvae directly onto the colonies. UC IPM adds two limits: biological control does not reduce the spread of the cucurbit viruses this aphid carries, and on the marketed parts of ornamentals it rarely gives satisfactory control on its own.
