Cucumber yellows virus (CuYV) is a species of virus that infects plants, specifically the cucumber and melon. It is transmitted by the greenhouse whitefly . The cucumber yellows virus genome was completely sequenced in 2003.
This effect causes young leaves to appear narrow and the entire plant to be stunted. [13] Specifically, CMV can cause cucumbers to turn pale and bumpy. The leaves of these plants turn mosaic and their rugosity is often changed, making leaves wrinkled and misshapen. Growth of these plants is usually also stunted and produces few flowers.
The species can be a major agricultural pest insect in North America. Spotted cucumber beetles cause damage to crops in the larval and adult stages of their life cycle. Larvae feed on the roots of the emerging plants, which causes the most damage since the young plants are more vulnerable. [1]

Squash mosaic virus (SqMV) is a mosaic virus disease common in squash plants and other plants, including melons, of the family Cucurbitaceae. [1] It occurs worldwide. [1] It is transmitted primarily by beetles, including the leaf beetle (Acalymma trivittata), spotted cucumber beetle (Diabrotica undecimpunctata), [2] [3] and 28-spotted ladybird beetle (Henosepilachna vigintioctopunctata), [1 ...
Eggs of this species measure about 0.6 millimetres (0.024 in) long and 0.3 millimetres (0.012 in) wide, and are elliptical in shape. The eggs are initially yellow or green but turn black. [3] The nymphs are initially green, but soon turn yellowish and resemble the viviparous adults. Nymphs that give rise to winged females may be pinkish. [3]
