Research Project: REFINING THE AREA-WIDE SUPPRESSION OF THE TARNISHED PLANT BUG IN MISSISSIPPI

Location: Southern Insect Management Research Unit

Project Number: 6402-22000-063-04
Project Type: Specific Cooperative Agreement

Start Date: Apr 10, 2008
End Date: Mar 31, 2011

Objective:
The objective of this cooperative research project is to demonstrate the destruction of wild hosts of the tarnished plant bug (TPB) from field, road, and ditch margins in April and may to reduce populations buildups and prevent it from being an early-season pest of cotton and to evaluate the costs of wild host destruction as compared to benefits in terms of reduces insecticide use for plant bug control.

Approach:
Selected wild hosts which are preferred reproduction hosts of plant bugs will be selectively sprayed with an herbicide or mowed during April and may in marginal areas around fields, roads, and ditches in a cotton producing area of the Delta measuring 4 x 4 miles. Plant bug populations on the remaining hosts will be measured weekly. Host plant density counts will be taken. Results will be compared to samples from 3 non-treated areas of the same size to measure the impact of the treatments on plant bug populations. Plant bug populations in cotton in the treated and untreated areas will be measured weekly during the growing season. Costs of the treatment and benefits to growers will be calculated from experimental data and from data collected from producers.
