Растения-хозяева

American serpentine leafminer has a wide host range including over 400 species from 28 families of both vegetable and ornamental crops. The main hosts include beans, capsicums, carrots, celery, cotton, chrysanthemums, cucumbers, garlic, gerberas, lettuce, melons, onions, peas, eggplants, and tomatoes (CABI, 2021). In Australia, L. trifolii has currently been detected on Carthamus tinctorius (safflower), Cannabis sativa (hemp), Gossypium sp. (cotton crops), Vigna unguiculata (black eyed peas) and on common weed species including Synedrella nodiflora (Cinderella weed), Tridax procumbens (coatbuttons or tridax daisy) and Physalis angulata (wild gooseberry).

Pest Status (ISPM 8 - 2021)

Краткое описание

There were two separate detections of Liriomyza trifolii (American serpentine leafminer) in Kununurra, northern WA in March 2021 and in Torres Strait (QLD) in May 2021. Following additional surveys in July 2021, a sample was collected near Bamaga in the Far Northern Biosecurity Zone 1 (FNBZ 1) in QLD.

After assessment of the pest’s biology, the geographically dispersed nature of detections, and the available tools for eradication; it is unlikely that American serpentine leafminer will be technically feasible to eradicate.

Synonyms: Agromyza phaseolunata (Frost, 1943); Liriomyza alliivora (Frick, 1955); Oscinis trifolii (Burgess, 1880)

Опасность

Liriomyza trifolii is a highly polyphagous pest and has a 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 may result in premature leaf drop, poor growth, and reduced crop yields.
