Pest categorisation of Milviscutulus mangiferae

Area of Science:

• Plant Health
• Entomology
• Pest Risk Analysis

Background:

• Milviscutulus mangiferae, the mango shield scale, is a polyphagous pest found globally in tropical and subtropical regions.
• Its presence in the EU is uncertain, with a recorded instance in Italy, but establishment is not confirmed.

Purpose of the Study:

• To perform a pest categorization of Milviscutulus mangiferae for the EU.
• To assess its potential as a Union quarantine pest.

Main Methods:

• Review of existing data on the pest's distribution, host range, biology, and pathways.
• Assessment of its potential for establishment and impact within the EU.

Main Results:

• Milviscutulus mangiferae has a wide host range, including economically important EU crops like citrus and avocado, and ornamental plants.
• Favorable climatic conditions in southern EU and host availability support its establishment and spread.
• Potential entry pathways include plants for planting, cut flowers, and fruits.

Conclusions:

• The mango shield scale poses a potential economic threat to EU agriculture and horticulture.
• It meets the criteria to be considered a potential Union quarantine pest.
• Phytosanitary measures are crucial to mitigate the risk of introduction and spread.
