Guava Moth (Fruit Driller)
Guava moth. Mention this pest to any feijoa lover living in Northland or Auckland, and you will undoubtedly receive a response somewhere along the spectrum from annoyance to rage.
Guava moth is the bane of many fruit growers and home gardeners particularly as it’s not overly selective when it comes to its host fruit. Hosts of guava moth include feijoas, macadamias, plums, loquat and citrus, just to name a few, with the moth migrating from host to host throughout the year.
Guava moth lays its eggs on host fruit, and hatching larvae then burrow directly into the fruit resulting in internal browning and early fruit drop. Pupation takes place on the ground, in loose soil and debris. The pest was first recorded in Northland over 20 years ago and has gradually spread south to Auckland, north Waikato and the Coromandel.
Asha Chhagan and Natalie Page from Plant & Food Research (Auckland) will discuss the MPI Sustainable Farming Fund (SFF) project initiated in 2017 to investigate sustainable management options for guava moth in New Zealand.
