Toxicity of Different Insecticides against Franklinellia invasor (Thysanoptera: Thripidae), a Mango Pest in Central America

Frankliniella invasor is an important pest of mango in Central America; however, information is limited concerning the activity of insecticides with different modes of action. Eight insecticides representing 5 different chemical classes were assayed for control of F. invasor in Costa Rica. The spinosyns, spinetoram, and spinosad were highly active, whereas malathion and alpha-cypermethrin were the least active. The neonicotinoids imidacloprid and thiamethoxam resulted in intermediate toxicity to this thrips pest.
