Observations about Some Unusual Cotton Pests in Tennessee during 2003

Scott D. Stewart


The following is intended to document observations on the biology, injury potential and management of several relatively unusual pests that occurred in Tennessee cotton fields during 2003. These pests include the clouded plant bug (Neurocolpus nubilus), Japanese beetle (Popillia japonica), corn root aphid (Anuraphis maidiradicis), and snails and slugs (Mollusca). With the exception of the clouded plant bug, economic damage appeared to be confined to only a few fields. The cotton square borer (Strymon melinus) and variegated leafroller (Platynota flavedana) were also observed in cotton more commonly than usual in 2003, but they are often present in low numbers every year and are not discussed here.
