Thrips are tiny insects – their sizes range between 0.5mm and 15mm in length and many are shorter than 5mm. But the damage they cause to crops is anything but small. A 2021 research paper found that in Indonesia “the damage to red chilli plants caused by thrips infestation ranges now from 20% to 80%”. In India, various thrips infestations in the late 2010s and early 2020s “damaged 40%-85% of chilli pepper crops in Karnataka, Andhra Pradesh and Telangana”.
In Africa, a number of thrips species feed on sugarcane and have been known to damage nearly 30% of the crop in a single hectare of a farm. High rates of destruction have been recorded in Tanzania and Uganda on onion and tomato crops.
