Attack of the Post Oak Grasshoppers?
Ed Riley, entomologist and Associate Curator of the Texas A&M
University Insect Collection, predicts Bryan-College Station is about
to experience the first big outbreak of post oak grasshoppers in
at least 14 years. Riley bases his prediction on observations made
on outings south of College Station and west of Bryan over the past
two weekends. In both areas, “large numbers of late-stage nymphs
are already hitting the oaks very hard,” says Riley. He suspects "that
within the week, some of these populations will start to reach maturity
and their damage become more noticeable."
The post oak grasshopper, Dendrotettix quercus Packard (Orthoptera:
Acrididae, Melanoplinae) feeds not only on post oak (Quercus stellata),
but also on water oak (Quercus nigra) and blackjack oak (Quercus
marylandica). Brazos County has already experienced a major assault
on oaks earlier this season from the tortricid complex in the Archips and
other species of caterpillars.
