Summary of the Express Pest Risk Analysis for Liriomyza huidobrensis Blanchard, 1926

Description

Liriomyza huidobrensis is a polyphagous species.Most of its host plants are commonly cultivated in PRA area. Hosts of this leaf miner include lettuce, cucumber, onion and many ornamental plants, (especially cultivated in greenhouses). Insect is potato, sugar beet, vegetables, ornamental plants pest in field crops .

Pest is native to Central and Eastern Europe but it presents also in Mediterranean region.

Considering climate changes scenarios for PRA area that is unlikely that pest will be able to survive winter in open field crops. However many experts suggest that likelihood of survive may increase due to climate changes (especially shorter and milder winter).

Correct identification and monitoring are crucial to reduce the pest spread.

Yellow sticky papers are efficient method used to trap out pests, especially in place of production and packaging workshops.

Additionally, the morphological similarity of L. huidobrensis to other pest species (of Agromyzidae family) can cause numerous misidentifications.

Visual controls of consigments may be insufficient, becouse of occurence of all pest life stages at the same time.

Rating of the likelihood of impact without use of phytosanitary measures: High

Ornamental plants, seedlings, vegetables are imported from areas of pest occurence

PRA experts suggest to clasify L. huidobrensis as quarantine officially regulated pest. L. huidobrensis spread may be limited by creation of protected zones in pest free areas.

In addition, legal regulation of host plants (and potential host plans) import should be actualized.

Spraying insecticide is commonly used as sufficient phytosanitary measure.
