Abstract

Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is a newly identified invasive pest in the Caribbean, and poses a significant threat to agriculture and trade in the region. Methods are needed to detect the presence and to monitor populations of this pest so that they can be effectively managed. Studies were initiated during the wet season in 2004 and continued in the dry season of 2005 to test 'CC' traps designed for detecting and monitoring the pest in hot peppers (Capsicum chinensis L.) under field conditions in St. Vincent. The experiments test three different base color traps (blue, yellow and white), the addition of dichlorvos (Vapona) as a killing agent, and the addition of ethylene glycol as an insect preservative. Average weekly catches were low at 0.01 to 0.18 S. dorsalis per CC trap per week. A sticky card trap (blue, yellow and white) experiment was also conducted in the dry season. Average weekly catches on the yellow sticky card traps were 19.8 S dorsalis per card per week. The potential benefits and shortcomings of using either or both of these detection methods are discussed.
