Pest categorisation of Selenaspidus articulatus
EFSA Journal. European Food Safety Authority
|May 13, 2025
Summary
The scale insect Selenaspidus articulatus poses a potential risk to EU agriculture, particularly to crops like citrus and olives. While currently limited to greenhouses in the EU, its polyphagous nature and host availability in southern regions warrant concern.
Area of Science:
- Plant Health
- Entomology
- Risk Assessment
Background:
- Selenaspidus articulatus (Hemiptera: Diaspididae) was identified as a pest of concern during a risk assessment of Jasminum polyanthum cuttings from Uganda.
- This polyphagous scale insect, likely originating from sub-Saharan Africa, is present globally and has been recorded in the Netherlands within greenhouses.
Purpose of the Study:
- To conduct a pest categorization of Selenaspidus articulatus for the European Union (EU).
- To assess the potential risks posed by S. articulatus to EU agriculture and identify phytosanitary measures.
Main Methods:
- Review of existing data on S. articulatus distribution, host range, and biology.
- Assessment of climate suitability and host availability within the EU.
- Evaluation against EFSA criteria for potential quarantine pests.
Main Results:
- S. articulatus is polyphagous, affecting 158 genera across 68 families, including EU crops like avocado, citrus, grape, and olive.
- Establishment is possible in southern EU countries due to host availability and climate suitability, and indoors in colder EU regions.
- The pest can cause yield loss and plant death through feeding, saliva injection, and reduced photosynthesis.
Conclusions:
- Selenaspidus articulatus meets all EFSA criteria for consideration as a potential quarantine pest.
- Phytosanitary measures are crucial to prevent entry, establishment, and spread within the EU.
- The pest poses a significant economic threat to EU agriculture.

01:31Taxonomy

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.Hierarchy of TaxonomyThe hierarchy that Carolus Linnaeus first...

13.9K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

01:06Fixed Action Patterns
15.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

01:46Types of Selection
39.8K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

01:09Preparedness and Phobias
86
Human fear responses to certain stimuli, such as darkness, heights, deep water, and blood, can often arise despite the absence of direct negative experiences. This phenomenon is rooted in evolutionary psychology, which posits that humans have developed a predisposition to fear stimuli that historically posed significant survival threats. This predisposition, known as preparedness, suggests that early humans who developed a fear of potentially dangerous entities, such as venomous snakes and...
