Studies initiated in 2005 were continued in 2008 to reassess action thresholds for the cotton fleahopper, Pseudatomoscelis seriatus (Reuter). Trials in 2008 were conducted in east (Burleson Co.) and central Texas (Tom Green Co.). Treatments included one, two or three automatic insecticide applications applied one week apart, current economic threshold and an untreated check. As in previous years of the study, insecticide treatments showed no significant yield advantages. However, the trial in Burleson County indicated that yields in the insecticide treatments were numerically higher than the untreated. These findings suggest insecticide application may be provide some benefit when moderate fleahopper population levels are present throughout the fruiting season. However, currently established thresholds appear to be adequate to maintain yields. After four years, it appears that thresholds in the Southern Blacklands are adequate but questions remain about the frequency. [ABSTRACT FROM AUTHOR] |
