A call to arms: novel strategies for thrips and tospovirus control

Thrips and the tospoviruses they transmit are some of the most significant threats to food and ornamental crop production globally. Control of the insect and virus is challenging and new strategies are needed. Characterizing the thrips-virus interactome provides new targets for disrupting the transmission cycle. Viral and insect determinants of vector competence are being defined, including the viral attachment protein and its structure as well as thrips proteins that interact with and respond to tospovirus infection. Additional thrips control strategies such as RNA interference need further refinement and field-applicable delivery systems, but they show promise for the knockdown of essential genes for thrips survival and virus transmission. The identification of a toxin that acts to deter thrips oviposition on cotton also presents new opportunities for control of this important pest.
