Summary

Numerous larvae were found in only one field of maize (Zea mays) on the 16th of December 2020. The field has been destroyed and a management program has been set in place. However, since the beginning of 2021, Spodoptera frugiperda has been found in several maize fields located throughout New Caledonia and is now considered has widely distributed in the country. At this stage, eradication is not considered as possible but the management program, based on monitoring, chemical control, development of biological control, adaptation of agronomic practices and communication with producers, is maintained.

Danger
Introduction of FAW in New Caledonia could have economic impacts on the maize industry but also on many other productions given the wide range of hosts of FAW.
