However, in the late 19th century, the entire species was nearly destroyed by the plant louse phylloxera accidentally introduced to Europe from North America. Native American grapevines include varieties such as Vitis labrusca, which is resistant to the bug. Vitis vinifera varieties were saved by being grafted onto the rootstock of Native American varieties, although there is still no remedy for phylloxera, which remains a danger to any vineyard not planted with grafted rootstock.

Aacanthocnema luehmannii is a species of jumping plant louse, first found on plants of the genus Allocasuarina in Australia. The species is characterised by exhibiting an elongate habitus; short Rs and short cubital forewing cells; ventral genal processes beneath the apical margin of its vertex; short antennae; and nymphs that are elongate and very sclerotised (scale-like). It lacks hinaria on its eighth antennal segment as well as sclerotised spurs on its hind tibia. Females of the species lack a posterior apical hook on their proctiger.

Acanthocasuarina acutivalvis is a species of jumping plant louse, first found on plants of the genus Allocasuarina in Australia. The species is characterised by exhibiting an elongate habitus; short Rs and short cubital forewing cells; ventral genal processes beneath the apical margin of its vertex; short antennae; and nymphs that are elongate and very sclerotised (scale-like). It possesses rhinaria on its fourth, sixth, eighth and ninth antennal segments; the species' hind tibia has one outer and two inner spurs, while the female's proctiger carries an apical hook posteriorly.Taylor, Gary S., et al.

Cardiaspina fiscella, the brown basket lerp or brown lace lerp, is a jumping plant louse species in the genus Cardiaspina originally found in Australia. It spread to New Zealand where it was found in 1996 near the Auckland airport. citing It feeds on eucalyptus, especially swamp mahogany, and is found in Victoria, eastern New South Wales, and southeastern Queensland, as well as the capital territory (ACT) around Canberra and on Norfolk Island. Cardiaspina fiscella has five nymphal instars, and as the instars moult they add a layer to their outside covering (casing), known as the "lerp".

Psyllidae, the jumping plant lice or psyllids, are a family of small plant- feeding insects that tend to be very host-specific, i.e. each plant-louse species only feeds on one plant species (monophagous) or feeds on a few closely related plants (oligophagous). Together with aphids, phylloxerans, scale insects and whiteflies, they form the group called Sternorrhyncha, which is considered to be the most "primitive" group within the true bugs (Hemiptera). They have traditionally been considered a single family, Psyllidae, but recent classifications divide the group into a total of seven families; the present restricted definition still includes more than 70 genera in the Psyllidae.

Brevicoryne brassicae, commonly known as the cabbage aphid or cabbage aphis, is a destructive aphid (plant louse) native to Europe that is now found in many other areas of the world.Hawaii Department of Entomology information page The aphids feed on many varieties of produce, including cabbage, broccoli (especially), Brussels sprouts, cauliflower and many other members of the genus Brassica, but do not feed on plants outside of the family Brassicaceae. The insects entirely avoid plants other than those of Brassicaceae; even though thousands may be eating broccoli near strawberries, the strawberries will be left untouched.University of Minnesota extension Cabbage aphids, from the genus Brevicoryne of the family Aphididae, are grayish-green, but a waxy covering gives them a grayish-white to powdery blueVirginia Tech Department of Entomology appearance.
