Guides
Phylloxera spinosa
Phylloxera spinosa is a gall-forming insect in the family Phylloxeridae, closely related to aphids. This species induces distinctive galls on its host plants through chemical secretions that manipulate plant tissue development. Like other phylloxerans, it has a complex life cycle involving multiple generations and winged dispersal forms. The species was described by Shimer in 1869 and is currently accepted as valid.
Phylloxera stanfordiana
Phylloxera stanfordiana is a species of phylloxeran insect in the family Phylloxeridae, order Hemiptera. It is closely related to aphids and shares their soft-bodied morphology and plant-feeding habits. The species was described by Ferris in 1919. Like other phylloxerans, it is known to induce gall formation on host plants through its feeding activity. The specific epithet 'stanfordiana' refers to Stanford University, where the type specimen was collected in 1904.
Phylloxera stoetzelae
Phylloxera stoetzelae is a species of phylloxeran, a group of tiny, soft-bodied, sap-sucking insects closely related to aphids. Members of the genus Phylloxera are known for inducing galls on host plants through chemical secretions that stimulate abnormal plant tissue growth. The species was named in honor of entomologist Mark Stoetzel. Like other phylloxerans, it likely completes a complex life cycle involving both parthenogenetic and sexual reproduction phases, with overwintering eggs hatching in spring to initiate gall formation on new growth.
Phylloxera texana
Phylloxera texana is a species of gall-inducing insect in the family Phylloxeridae, described by Stoetzel in 1981. Like other phylloxerans, it is closely related to aphids and induces abnormal plant growths (galls) on its host plants through chemical secretions that manipulate plant tissue development. The species is presumably associated with pecan or related hickory species given its genus affiliation and geographic name, though specific host records and detailed biology remain poorly documented in available literature.
Phylloxera tuberculifera
Phylloxera tuberculifera is a gall-forming insect species in the family Phylloxeridae, first described by Duncan in 1922. As with other phylloxerans, this species induces abnormal plant growths (galls) on host plants through chemical secretions that redirect plant tissue development. The species belongs to a genus containing several economically significant pests, particularly of pecan and grape. Specific host associations and detailed biology for P. tuberculifera remain poorly documented in published literature.
Phylloxeridae
phylloxerans, phylloxerids
Phylloxeridae is a small family of plant-parasitic hemipterans comprising approximately 75 described species across 11 genera and two subfamilies (Phylloxerininae and Phylloxerinae). These minute insects are closely related to aphids and adelgids, with which they share the superfamily Phylloxeroidea. They are specialized gall-formers on deciduous trees and perennial fruit crops, with complex life cycles involving cyclical parthenogenesis and host alternation between primary woody hosts and secondary herbaceous hosts. The family includes the economically devastating grape phylloxera (Daktulosphaira vitifoliae), responsible for the 19th-century European vineyard crisis.
