Resumen

In October 2020, Liriomyza huidobrensis (serpentine leafminer) was detected causing damage on field grown vegetables in Sydney, New South Wales. After delimiting surveys, serpentine leafminer was detected at several sites in New South Wales and at a property in southern Queensland. Due to the pest’s biology and distribution, it was determined that serpentine leafminer is not eradicable from Australia.

Synonyms: Agromyza huidobrensis (Blanchard, 1926), Liriomyza cucumifoliae (Blanchard, 1938), Liriomyza decora (Blanchard, 1954), Liriomyza dianthi (Frick, 1958), Liriomyza langei (Frick, 1951)

Peligro

Liriomyza huidobrensis is a highly polyphagous pest with hosts in 15 families. It has a very wide global distribution. Leaf damage occurs through puncture wounds from adult feeding and egg deposition, and the larvae tunnel, or mine, within the leaf tissue. The damage can reduce the photosynthetic capacity of the plants. Severe unmanaged infestations of it may result in premature leaf drop, poor growth, and reduced crop yields. Serpentine leafminer is present in New South Wales and Southern Queensland. As it is not widely distributed within Australia, it is currently under regional official control for Western Australia.
