Worldwide distribution. On tomato, capsicum (see Fact Sheet no. 106), melon, onion (see Fact Sheet no. 117), and many other crops. An important pest.
Thrips are small insects, living within the buds of leaves and fruit, sucking the sap; leaves become brown on the underside, and fruit show silver scars.
Eggplant, tomato, melon, onion, and many other hosts are attacked, as well as weeds.
Natural enemies: predatory thrips prey on plant-eating thrips, and there are other predators.
Cultural control: avoid over-lapping crops; rotate crops; grow yard-long beans between rows to stop spread; destroy weeds; burn, or bury crop remains after harvest.
Chemical control: PDPs: derris, chilli, or neem; or soap, horticultural or white oils; use the biopesticide, spinosad. Alternatively, synthetic pyrethroids, but they are likely to kill natural enemies.
