IPPC Pest Reporting Summary – March – April 2026


enter image description here

Pest reporting is a key component of the National Reporting Obligations (NROs) under the International Plant Protection Convention (IPPC). Timely and transparent sharing of pest information helps prevent the introduction and spread of quarantine pests worldwide. Practical guidance on fulfilling the NROs is available through the IPPC e-learning course on NROs.

Selected reports for March and April 2026 of high phytosanitary relevance are highlighted below.

Title Summary Country Link to report

Pest reporting through national or regional systems

Several NPPOs communicate pest occurrences through national or regional reporting systems
Pest Summary Country Source
Dacus frontalis (Diptera: Tephritidae) The NPPO of France reported the first finding of Dacus frontalis on its territory following the detection of larvae and adult specimens associated with Cucurbita pepo (courgette) production in Alpes-Maritimes. Official phytosanitary measures were implemented in a demarcated area, including enhanced surveillance, destruction of infested fruits, restrictions on planting host plants, and awareness-raising activities. The officially declared pest status is “Transient, detection in two plots of Cucurbita pepo, actionable, under eradication.” France EPPO Reporting Service (RS 2026/061)*
Bactrocera zonata (Diptera: Tephritidae) Greece reported the first occurrence of Bactrocera zonata (peach fruit fly) in its territory. The pest was detected through trapping activities in the Attica Region between June and December 2025, with 43 adult males captured in 35 traps across an area of approximately 50 km². A regulated area has been established and official phytosanitary measures are being applied. The officially declared pest status is “Present, not widely distributed and under official control.” Greece EPPO Reporting Service (RS 2026/060)*
Phytophthora pluvialis (Peronosporales: Peronosporaceae) The NPPO of Ireland reported the first finding of Phytophthora pluvialis following annual forest surveys conducted since 2022. The pathogen was detected in a forest plantation in Cork County, associated with symptomatic western hemlock (Tsuga heterophylla) and Douglas-fir (Pseudotsuga menziesii). Detection was confirmed through real-time PCR and subsequent water baiting assays. The officially declared pest status is “Present, at low prevalence, in specific parts, where host crop(s) are grown”. Ireland EPPO Reporting Service (RS 2026/097)*
Scirtothrips dorsalis (Thysanoptera: Thripidae) The NPPO of the Netherlands reported the confirmed finding of Scirtothrips dorsalis cryptic species East Asia on ornamental plants for planting in commercial trading facilities in Gelderland Province. The pest was detected during export inspections and subsequent surveys. Official phytosanitary measures were implemented, including blocking affected plant lots and eradication actions. The officially declared pest status is “Transient: actionable, under eradication”. Netherlands NVWA Pest Report
Cyrtogenius luteus, Cyclorhipidion bodoanum, Cyclorhipidion distinguendum, Dryoxylon onoharaense (Coleoptera: Curculionidae: Scolytinae) The NPPO of Slovenia reported the first findings of four non-European Scolytinae species during trapping activities conducted in the Goriška region near the Italian border. The pests were detected through scientific surveillance trapping and confirmed using morphological and molecular methods. The officially declared pest status for all four species is “Transient, actionable, under surveillance”. The NPPO indicated that surveys for non-European Scolytinae will be included in the 2026 national survey programme. Slovenia EPPO Reporting Service (RS 2026/064)*
Spodoptera frugiperda (Lepidoptera: Noctuidae) The NPPO of Spain reported the first detection of Spodoptera frugiperda (fall armyworm) in its territory following the capture of three male adults in a maize field in Andalucía in November 2025. The identity of the pest was confirmed by the National Reference Laboratory. Official phytosanitary measures are being implemented, including insecticide treatments, establishment of a trapping network, and inspections of facilities importing host plants. The officially declared pest status is “Transient, the pest has been detected exclusively in one trap, actionable, under surveillance.” Spain EPPO Reporting Service (RS 2026/057)*
Bactrocera dorsalis (Diptera: Tephritidae) The NPPO of Spain reported the first finding of Bactrocera dorsalis (oriental fruit fly) in its territory following the capture of three adults in a trap located in an orchard in Cantabria in October 2025. The identity of the pest was confirmed by the Regional Laboratory. Official phytosanitary measures were implemented, including intensive surveillance and safe disposal of fallen fruit from host plants within a 500 m radius of the original trap. The officially declared pest status is “Transient, actionable, under eradication.” Spain EPPO Reporting Service (RS 2026/058)*
Pochazia shantungensis (Hemiptera: Ricaniidae) The NPPO of Switzerland reported the first finding of Pochazia shantungensis following the detection of a specimen recorded on the citizen science platform iNaturalist.

Enhancing pest reporting collaboration

Individual efforts by each country collectively drive the actions needed to safeguard global plant health. We encourage NPPOs to continue their reporting efforts through the IPP by logging in as Official Contact Point (OCP), navigating to the country page dashboard, providing the necessary information, and submitting the pest report.

If your NPPO uses a different platform or national system to report pest outbreaks, please inform the IPPC Secretariat by writing to [email protected] and copying [email protected].
