Psyllids
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. Psyllid fossils have been found from the Early Permian before the flowering plants evolved. The explosive diversification of the flowering plants in the Cretaceous was paralleled by a massive diversification of associated insects, and many of the morphological and metabolic characters that the flowering ...

Pachypsylla
''Pachypsylla'' is a genus of psyllids. Species of the genus ''Pachypsylla'' lay eggs on the leaves of the ''Celtis occidentalis'' tree. Upon hatching, the young psyllids become encased in a gall which the young leaf parts grow in response to the infestation. Species The following species are recognised in the genus ''Pachypsylla'': *''Pachypsylla celtidisasterisca'' Riley, 1890 *''Pachypsylla celtidiscucurbita'' Riley, 1890 *''Pachypsylla celtidisgemma'' Riley, 1885 – hackberry bud gall maker *''Pachypsylla celtidisglobula'' Riley, 1890 *''Pachypsylla celtidisinteneris'' Mally, 1894 *''Pachypsylla celtidismamma'' (Riley, 1881) – hackberry nipplegall maker *''Pachypsylla celtidispubescens'' Riley, 1890 *''Pachypsylla celtidisumbilicus'' Riley, 1890 *''Pachypsylla celtidisvesicula'' Riley, 1890 – hackberry blistergall psyllid *''Pachypsylla cohabitans'' Yang & Riemann, 2001 *''Pachypsylla dubia'' Patch, 1912 *''Pachypsylla pallida'' Patch, 1912 *''Pachypsylla tropicala' ...

Aphid
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, coloni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acizzia
''Acizzia'' is a genus of psyllids that primarily feed on ''Acacia'' and ''Albizia'' species. Many species are known from Australia and have become widespread as their host plants are popular garden specimens. Damage to the leaves is generally mild. Economic damage on plantation species is occasionally reported. ''Acizzia'' are also known for their consumption of ''Mimosa ''Mimosa'' is a genus of about 590 species of herbs and shrubs, in the mimosoid clade of the legume family Fabaceae. The generic name is derived from the Greek word (''mimos''), an "actor" or "mime", and the feminine suffix -''osa'', "resembl ...''.
