Summary of Investigations into Timing and Frequency of Insecticide Applications for Cotton Fleahopper

C. G. Sansone, Texas Cooperative Extension, 7887 US 87 N, San Angelo, TX 76901, R.R. Minzenmayer, Texas AgriLIFE Extension Service, 613 Hutchins Ave, Ste. 302, Ballinger, TX 76821, and Dale A. Mott, 3151 SE Innerloop, STE A, Georgetown, TX 78626.

The cotton fleahopper is considered a key pest in the eastern production regions of Texas. Both adults and nymphs feed on small squares which can result in significant yield losses. The situation in the western production regions of Texas is different because the cotton fleahopper is an occasional pest. Recent research involving mechanical removal of squares indicate that current varieties can compensate for significant square loss early in the season. This is the second year of a study to determine the best control strategies for cotton fleahopper and to determine if thresholds need to be changed due to the introduction of new, high yielding varieties. Studies in 2005 indicated that despite setting more squares with insecticide applications, yields were not significantly different from the control plots. The study was repeated in 2006 to determine if this same trend continues.
