Pest categorisation of Phlyctinus callosus.
EFSA Journal. European Food Safety Authority
|August 11, 2021
Summary
Phlyctinus callosus, a pest from South Africa, poses a risk to the EU. Its larvae feed on roots, and adults damage fruits like apples and grapes, with suitable EU climates for establishment.
Area of Science:
- Plant Health
- Entomology
- Pest Risk Analysis
Background:
- Phlyctinus callosus (Coleoptera: Curculionidae) is a polyphagous pest originating from South Africa.
- It has established in Australia, New Zealand, Reunion, and St Helena.
- The pest has been intercepted in Europe on imported apples and peaches.
Purpose of the Study:
- To conduct a pest categorisation of Phlyctinus callosus for the EU territory.
- To assess its potential as a Union quarantine pest.
Main Methods:
- Review of existing data on pest biology, distribution, and host range.
- Assessment of potential entry pathways, establishment, and spread within the EU.
- Evaluation against criteria for Union quarantine pest status.
Main Results:
- Phlyctinus callosus larvae develop in soil, feeding on roots of various plants.
- Adults damage fruits (apples, nectarines, grapes, strawberries, blueberries) and foliage.
- Potential entry pathways include table grapes and plants for planting.
- EU climates are considered suitable for pest establishment.
- Natural spread is limited, but movement of host plants and fruits could facilitate spread.
Conclusions:
- Phlyctinus callosus meets the criteria for assessment as a potential Union quarantine pest.
- Phytosanitary measures, including prohibition of soil/growing media, can mitigate entry risks.

184
The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...

Taxonomy is the science of defining and naming groups of biological organisms based on shared characteristics. It uses a hierarchy of increasingly inclusive categories with Latin names. The smallest units of taxonomy, species and genus, are used to assign a formal, taxonomic name to each species in a system. This classification system, referred to as binomial nomenclature, was formalized by Carolus Linnaeus in the 18th century.

01:26Bacterial Phylum Planctomycetes
168
Planctomycetes are a group of morphologically distinct bacteria predominantly classified into two orders: Planctomycetales and Brocadiales. These gram-negative bacteria exhibit unique features, including division by budding and the presence of stalks or appendages. Their cells are often found in rosette arrangements, and they are notable for possessing an S-layer in their cell envelope, which is relatively uncommon among bacteria. Additionally, Planctomycetes frequently exhibit intracellular...

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...
