Results Without insecticides, the stink bug/plant bug complex would cause extensive damage to cotton in most areas of production. We have determined that cotton requires insecticide intervention when 20 half-grown (quarter-sized) bolls experience damage from stink bugs. Additionally, chemicals elicited from bugs and from damaged bolls have been identified. We have also developed prototype hand-held instrumentation that detects damaged bolls. Research is currently underway that will relate economic losses to intensity of chemical signals detected by advanced instrumentation. IMPACT: 2003/07 TO 2005/07 As low-cost hand-held instrumentation is perfected, time involved in determining damage to bolls will be reduced. We expect that large sprayers fitted with chemical sensors can spray only when the chemical intensity signifies economic populations are present.
