Related Topics
Flower thrips damage crops through feeding and oviposition, which result in deformation of growing tissues and lead to yield losses in harvested fruits and vegetables, as well as esthetic damage to flowers. They can cause significant economic damage to a range of crops, including citrus, blueberries, strawberries, field pepper, and ornamentals. Field identification of different flower thrips species is difficult without expert help.
IPM Florida resources
Several invasive species of thrips have established in Florida and become pests of vegetable, ornamental, and agronomic crops. Damage to crops results from thrips feeding and egg-laying injury, thrips vectoring plant diseases, the cost of using control tactics, and the loss of pesticides due to resistance.

The Department of Entomology and Nematology maintains tripartite priorities consistent with the mandate given to full-service landgrant universities and associated experiment stations: Research, Extension, and Academics. These programs are facilitated with state funding, extramural contract and grant funding, donations and gifts, and the collaborative efforts of cooperating agencies and institutions. The Department has coordinated faculty efforts and strengths into what could be considered major thrust areas for the Department. These areas of emphasis include: Behavior, Ecology, and Systematics; Biological Control; Medical, Veterinary and Urban Entomology; Nematology; Pest Management; and Physiology, Biochemistry, and Genetics.
