Abstract
The South American tomato pinworm, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is difficult to manage this invasive pest. In particular in open field cultivation systems, insecticide treatment is still the most popular management strategy. As a result, both in South America and in Europe, pesticide resistance to several chemical types of insecticides has been documented. According to the chemical class, changed target-site sensitivity and/or increased detoxification are the key mechanisms causing the unusually quick development of pesticide resistance in this species. Low frequency resistance alleles are particularly concerning against newer chemistries since they have a propensity to spread along with invasions, making tomato pinworm very challenging to eradicate. To keep tomato pinworm infestations below economic damage thresholds and ensure sustainable yields, it is crucial to undertake integrated control programmes and suitable resistance management measures as part of such programmes.
