The invasive Liriomyza huidobrensis (Diptera: Agromyzidae): Understanding its pest status and management globally. Journal of Insect Science. 28:1-27. Interpretive Summary: The invasive leafminer Liriomyza huidobrensis is a pest insect that feeds on more than 150 vegetable and flower crops, including potatoes, beans, spinach, lettuce, tomatoes, squash, and chrysanthemum, causing millions of dollars in crop losses globally. Although native to South America, this leafminer is highly invasive and has spread to Europe, Asia, Africa, North America, and the Middle East. Here we report on the history, biology and pest status of this leafminer and its global invasions. This research is expected to be of interest to quarantine officials, pest managers, and scientists involved in efforts to manage and contain this destructive pest.
Technical Abstract: Liriomyza huidobrensis is native to South America but has expanded its range and invaded many regions of the world, primarily on flowers and to a lesser extent on horticultural product shipments. As a result of initial invasion into an area, damage caused was usually significant but not necessarily sustained. Currently it is an economic pest in selected native and invaded regions of the world. Adults cause damage by puncturing abaxial and adaxial leaf surfaces for feeding and egg laying sites. Larvae mine the leaf parenchyma tissues which can lead to leaves drying and wilting. We have recorded more than 350 host plant species from 48 families and more than 106 parasitoid species. In a subset of the Argentinian data, we found that parasitoid community composition attacking L. huidobrensis, differ in cultivated and uncultivated plants. No such effect was found at the world level, probably due to differences in collection methods in the different references. We review the current pest status and management strategies, and discuss the potential for further regional invasions or expansions on the basis of climate change modeling.
