Psylloidea

Belongs within: Sternorrhyncha.Contains: Trioza, Chermes, Psyllinae, Spondyliaspinae, Ciriacreminae, Aphalarinae. The Psylloidea, jumping plantlice or lerp insects, are a group of small plant-sucking bugs, some of which are notable agricultural pests. Nymphs commonly inhabit protective structures, such as leaf galls induced in host plants or wax secretions produced from the abdomen. Psylloids first appear in the… Continue reading Psylloidea

Psyllinae

Belongs within: Psylloidea. The Psyllinae are a group of plant-lice with the R vein separating in the wing before the M and Cu veins, and an undivided male proctiger (Heslop-Harrison 1961). The Asian citrus psyllid Diaphorina citri is a particularly notorious species as it acts as a vector of citrus greening disease (Huanglongbing). Members of… Continue reading Psyllinae

Aphididae

Belongs within: Aphidoidea.Contains: Cinara, Aphidini. The Aphididae, aphids, are a morphologically diverse group of phytophagous bugs with differentiated parthenogenetic and sexually reproducing generations. Commonly, populations will go through several parthenogenetic all-female generations before producing a single sexual generation at the end of the growing season. In some species living in milder climates or more protected… Continue reading Aphididae

Coccidae

Belongs within: Coccoidea.Contains: Lecanium, Coccus. The Coccidae, soft scales, are characterised by the presence in females of paired triangular or rounded plates at the base of an anal cleft. They include both wax-covered and naked species. Several species are significant crop pests such as the hemispherical scale Saissetia coffeae and the soft wax scale Ceroplastes… Continue reading Coccidae

Aphidini

Belongs within: Aphididae. The Aphidini are a group of aphids in which the antennae are always shorter than the body, and stigmal pori on the first and second abdominal segments are relatively distant from each other. Economically significant species include the cotton aphid Aphis gossypii which attacks a wide range of hosts including several cucurbit… Continue reading Aphidini

Sternorrhyncha

Belongs within: Hemiptera.Contains: Aleyrodidae, Psylloidea, Coccinea, Aphidoidea. The Sternorrhyncha are a group of small plant-sucking bugs including the aphids, scales, whiteflies and plantlice. They are commonly sedentary except when dispersing, moving little if at all. They are usually thought to be divided between two main lineages, of which the Psyllomorpha (including the whiteflies and plantlice)… Continue reading Sternorrhyncha

Aleyrodidae

Belongs within: Sternorrhyncha.Contains: Aleyrodinae. The Aleyrodidae, whiteflies, are small plant-sucking bugs with immobile nymphs, some species of which are notorious crop pests. Adults are soft-bodied with reduced wing venation and are usually covered with a white, waxy powder (Carver et al. 1991). The earliest fossil whiteflies are known from Early Cretaceous Lebanese amber (Grimaldi &… Continue reading Aleyrodidae

Ortheziidae

Belongs within: Coccinea. The Ortheziidae are a group of scale insects in which females bear a dorsal anal opening surrounded by six setae and a band of pores. Female antennae have three to eight segments with a stout apical spur on the terminal segment (Carver et al. 1991). Soft waxy scales Published 28 April 2008… Continue reading Ortheziidae

Greenideidae

Belongs within: Aphidoidea. The Greenideidae are a group of aphids that typically bear long siphunculi with correspondingly long setae. <==Greenideidae |–CervaphidinaeWP02 `–Greenideinae [Greenideini]WP02 | i. s.: ‘Aphis’ macrostyla Heer 1853WP02 | ‘Aphis’ morloti Heer 1853WP02 | ‘Aphis’ pallescens Heer 1853WP02 |–Stomaphis eupetes Wegierek & Mamontova 1993WP02 |–MesotrichosiphumWP02 |–AllotrichosiphumWP02 |–Schoutedenia ralumensisCGW91 |–Anomalaphis compereiCGW91 |–Meringosiphon paradisicumCGW91 |–EonaphisCGW91… Continue reading Greenideidae
