Phylloxera deplanata
pecan leaf phylloxera, pecan phylloxera
Phylloxera deplanata is a tiny, soft-bodied insect in the family Phylloxeridae, closely related to aphids. It is a significant pest of pecan trees (Carya illinoinensis), causing the formation of galls on leaves, shoots, and nuts. The species overwinters as eggs in bark crevices and emerges in spring to feed on new growth, inducing abnormal plant tissue development. Unlike the pecan leaf phylloxera (which forms galls on leaves only), this species attacks shoots and nuts, making it more economically damaging. Heavy infestations can reduce yield, impair tree vitality, and diminish subsequent production.
Phylloxera symmetrica
Phylloxera symmetrica is a gall-forming insect in the family Phylloxeridae, closely related to aphids. Like other phylloxerans, this species induces abnormal plant growths (galls) on host plants through chemical secretions that manipulate plant development. The species was described by Pergande in 1904. Members of the genus Phylloxera are known for complex life cycles involving both sexual and asexual generations, with overwintering eggs and multiple gall-forming generations per year.

The species is associated with hickory trees (Carya spp.) as its primary host. Woolly aphids in this genus are known for complex life cycles that typically involve host alternation between a primary woody host and secondary herbaceous hosts, though specific details for P. caryae are not well documented in available sources.
