Management
Due to the recent introduction of chilli thrips into the U.S., pest management programs are still being developed. Preliminary tests suggest that foliar sprays with insecticides containing acephate, imidacloprid, or spinosad are effective for pest control on ornamental landscape plants (Table 2). The use of insecticides containing pyrethroids (such as bifenthrin, cyfluthrin and permethrin) is not recommended because they are not very effective against chilli thrips, and are more damaging to beneficial insects.
