Application Of Computer Intensive Methods To Evaluate The Performance Of A Sampling Design For Use In Cotton Insect Pest Management, J. L. Willers, W. L. Ladner, J. M. Mckinion, W. H. Cooke

Conference on Applied Statistics in Agriculture

A scouting protocol for cotton insect pests was developed which combines high resolution, multispectral remotely sensed imagery with a belt transect that crosses rows of cotton. Imagery was used to determine sample site selection while estimating plant bug abundance in a more than 200 ac. cotton field in 1997. Tarnished plant bug (Lygus lineolaris) counts were acquired using a standard drop cloth for each of eight rows along a transect. The sample data indicated that plant bug population densities spatially vary as a function of different spectral (color) classes present on the imagery. We postulate that such classified …
