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.

Pest reporting through the International Phytosanitary Portal (IPP)

Selected reports for May 2026 of high phytosanitary relevance are highlighted below.

Title	Summary	Country	Link to report
Drosophila suzukii (Diptera: Drosophilidae)*	The NPPO of Colombia reports the detection of Drosophila suzukii in areas of Antioquia, Santander and Boyacá. Following confirmation of pest presence, the NPPO intensifies official monitoring activities, through trapping and fruit sampling in various growing regions across the country. The officially declared pest status is “Present: not widely distributed and under official control”.	Colombia	Here
Bactrocera dorsalis (Diptera: Tephritidae)*	The NPPO of the United States removes the Bactrocera dorsalis quarantine area in California, after three generations had elapsed since the date of the last pest detection. The officially declared pest status is “Absent: pest eradicated”.	United States	Here
Anastrepha ludens (Diptera: Tephritidae)	The NPPO of the United States reports the establishment of a quarantine area in California (La Mesa, San Diego County) due to the detection of a mated female Anastrepha ludens (Mexican fruit fly) at the end of February. The quarantine area was expanded at the beginning of March in response to the detection of another fly. To prevent the spread of the pest, safeguarding measures and restrictions are applied on the interstate movement of regulated articles. The pest is also present in three areas under quarantine in Texas. The officially declared pest status is “Present: not widely distributed and under official control”.	United States	Here
Anastrepha serpentina (Diptera: Tephritidae)	The NPPO of the United States establishes quarantine areas in Texas following the detection of Anastrepha serpentina (Sapote fruit fly) in Rio Hondo and Harlingen of Cameron County and in Alamo, Hidalgo County. Measures are applied on the interstate movement of regulated articles to prevent the spread of the pest. The officially declared pest status is “Present: not widely distributed and under official control”.	United States	Here
Cydalima perspectalis (Lepidoptera: Crambidae)	The NPPO of the United States expands the quarantine area including counties in Virginia in response to the confirmed detection of Cydalima perspectalis (box tree moth) the last summer. Regulations on the interstate movement of regulated articles are implemented to prevent the spread of the pest. The officially declared pest status is “Present: not widely distributed and under official control”.	United States	Here

Pest reporting through national or regional systems

Several NPPOs communicate pest occurrences through national or regional reporting systems:

Pest	Summary	Country	Source
Grapevine flavescence dorée phytoplasma (‘Candidatus Phytoplasma vitis’)	(Acholeplasmataceae: Phytoplasma) The NPPO of Germany reports the detection of Grapevine flavescence dorée phytoplasma (‘Candidatus Phytoplasma vitis’) in its territory. The disease, which had been eradicated in 2022 from the country, was identified in Vitis vinifera (grapevine plants) at the end of 2025 in three locations in Baden-Württemberg, as part of national surveys. Two outbreaks were detected in vine nurseries and another one in young grapevine plants established in 2024. Control measures and tracing investigations are implemented. The officially declared pest status is “Present, at low prevalence, in specific parts of the Member State, where host crop(s) are grown, under eradication.”	Germany	EPPO Reporting Service (RS 2026/102)*
Sirococcus tsugae (Diaporthales: Gnomoniaceae)	The NPPO of Germany reports the presence of Sirococcus tsugae, which was found on Cedrus atlantica trees of a forest in in North Rhine-Westphalia. Phytosanitary measures will be decided. The officially declared pest status of S. tsugae in Germany is “Present, only in some parts of the Member State concerned”.	Germany	EPPO Reporting Service (RS 2026/113)*
Scirtothrips aurantii (Thysanoptera: Thripidae)	The NPPO of Italy confirmed the first finding of Scirtothrips aurantii (South African citrus thrips) in Sicily. The officially declared pest status in Italy is “Present, under eradication”.	Italy	EPPO Reporting Service (RS 2026/120)*

Early warning information from scientific and other sources

The following information is shared for awareness and early warning purposes and does not constitute pest reporting under the National Reporting Obligations (NROs). These records originate from scientific publications and other information sources that may provide early indications of phytosanitary developments of potential interest. In some cases, the sources of information might not have been confirmed with the corresponding National Plant Protection Organization (NPPO) at the time of publication and should therefore not be interpreted as official declarations of pest status by the NPPO concerned, the IPPC Secretariat, or FAO.

The IPPC Secretariat draws on information from a range of publicly available sources that contribute to phytosanitary awareness and preparedness, including scientific publications, reporting services, and other information products developed by partner organizations and institutions. The IPPC Secretariat and the FAO assume no liability for the accuracy or completeness of this information, nor for any actions taken in reliance thereon. These pest reports should be used with these limitations in mind:

• Cryphonectria carpinicola (Diaporthales: Cryphonectriaceae) is reported in Azerbaijan. Additional information can be found in the EPPO Reporting Service (RS 2026/124)*.

• The presence of Curtobacterium flaccumfaciens pv. flaccumfaciens (Micrococcales: Microbacteriaceae) is recorded in Greece. Additional information is available in the EPPO Reporting Service (RS 2026/125)*.

• The first finding of Popillia japonica (Coleoptera: Scarabaeidae) on soybeans is documented in Iraq. Additional information can be found in the EPPO Reporting Service (RS 2026/118)*.

• The first report of Ponticulothrips diospyrosi (Thysanoptera: Phlaeothripidae) is documented in Italy and Switzerland. Additional information is available in the EPPO Reporting Service (RS 2026/122)*.

• The first finding of Amrasca biguttula (Hemiptera: Cicadellidae) is reported in Turkey. More information can be found in the EFSA Plant Health Newsletter on Horizon Scanning April 2026***, and in the EPPO Reporting Service (RS 2026/117)*.

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].
