Phylloxera notabilis
Pecan Leaf Phylloxera
Phylloxera notabilis is a gall-forming insect in the family Phylloxeridae, closely related to aphids. It is a significant pest of pecan trees (Carya illinoinensis), forming characteristic galls on leaf tissue. The species has host-associated populations on both pecan and water hickory (Carya aquatica), with documented differences in bacterial diversity between these populations. Unlike the more destructive pecan phylloxera (Phylloxera devastatrix), which attacks shoots and nuts, P. notabilis primarily damages leaves and may cause defoliation in heavy infestations.
