Phylloxera castaneae
Phylloxera castaneae is a gall-forming insect in the family Phylloxeridae, closely related to aphids. The species induces abnormal plant growths (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 both parthenogenetic and sexual reproduction. The species name indicates an association with Castanea (chestnut) hosts, though specific details about its biology remain poorly documented in available literature.
