New data on quarantine pests and pests of the EPPO Alert List
By searching through the literature, the EPPO Secretariat has extracted the following new data concerning quarantine pests and pests included (or formerly included) on the EPPO Alert List, and indicated in bold the situation of the pest concerned using the terms of ISPM 8.
- New records
Drosophila suzukii (Diptera: Drosophilidae – EPPO A2 List) is first reported from Colombia. It was detected in several areas in the departments of Antioquia, Santander and Boyacá, only on strawberry. Official surveys are conducted to assess the distribution of the pest in the country (IPPC, 2026).
The pest status of Drosophila suzukii in Colombia is officially declared as: Present, not widely distributed and under official control.
Squash vein yellowing virus (Ipomovirus cucurbitavenaflavi, SqVYV - EU Quarantine Pest 2019/2072 Annex II A) is first reported from India. It was detected in Varanasi (Uttar Pradesh) on symptomatic bottle gourd (Lagenaria siceraria) and cucumber (Cucumis sativus) during the 2022 and 2023 growing seasons. The pathogen was initially identified using high-throughput sequencing (HTS) and this was validated by RT-PCR testing. This is the first finding of SqVYV in India and the first record of L. siceraria as a host (Krishnan et al., 2026). Present, restricted distribution.
Tomato spotted wilt virus (Orthotospovirus tomatomaculae, TSWV – EPPO A2 List) is first reported from Mali. It was detected on symptomatic peanut (Arachis hypogaea) and tomato (Solanum lycopersicum) plants at the Sotuba Research Station, Bamako Capital District in the 2024 growing season (Bagayoko et al., 2026). The pest was identified by molecular testing. Present, restricted distribution.
Meloidogyne enterolobii (EPPO A2 List) is first reported from Sri Lanka. It was detected on guava (Psidium guajava), capsicum (Capsicum spp.) and tomato (Solanum lycopersicum) plants in the North Western, Central and Western provinces. The pest was identified by molecular testing (Rajapakse et al., 2026). Present, widely distributed.
- Detailed records
In Indonesia, citrus tristeza virus (Closterovirus tristezae -CTV - EPPO A2 List) occurs in Bali province (Nusa Tenggara) (Nurulita et al., 2026).
In Canada, the potato cyst nematode Globodera rostochiensis (EPPO A2 List) is first reported from Manitoba. It was detected in a single field (72 hectares) on a farm in south-western Manitoba. Official measures are applied (IPPC, 2026)
The pest status of Globodera rostochiensis in Canada is officially declared as: Present, not widely distributed and under official control.
In Brazil, huanglongbing was first reported from Rio Grande do Sul in early June 2026 in a family orchard in the municipality of Palmitinho, in the Médio Alto Uruguai region, near the border with Santa Catarina as part of the official surveys. Official measures have been applied and the outbreak was declared eradicated on June 11th. (Governo do estado Rio Grande do Sul, 2026-06-09 and 2026-06-11). The introduction was likely linked to illegal movement of infested seedlings. The press release does not mention the Liberibacter species that was identified. Both ‘Candidatus Liberibacter americanus’ (EPPO A1 List) and ‘Candidatus Liberibacter asiaticus’ (EPPO A1 List) occur in Santa Catarina state. Further surveys will be conducted in a radius of 2.4 km around the outbreak. Eradicated in Rio Grande do Sul.
In Ghana, Diaphorina citri (Hemiptera: Psyllidae – EPPO A1 List) was first reported in 2022 from the Volta region on Murraya paniculata plants grown for ornamental purposes (EPPO RS 2023/161). Ninsin et al. (2025) report the presence of D. citri in Volta, Eastern, and Greater Accra regions on orange (Citrus x aurantium var. sinensis) and lemon (C. x limon).
In India, Liriomyza trifolii (Diptera: Agromyzidae - EPPO A2 List) is causing damage on bottle gourd (Lagenaria siceraria) in Rajasthan (Kumawat et al., 2026).
In Taiwan the causal agent of laurel wilt -Harringtonia lauricola (EPPO Alert List) -and its principal vector, Xyleborus glabratus (Coleoptera: Curculionidae: Scolytinae – EPPO Alert List), are known to occur naturally. However, the disease itself (laurel wilt) had not been previously documented in the country. In 2025, surveys were conducted in commercial orchards of avocado (Persea americana) presenting symptomatic trees. Morphological and molecular tests confirmed the occurrence of laurel wilt (Gazis et al., 2026).
In Belgium, only 29 specimens of Monochamus galloprovincialis (Coleoptera: Cerambycidae - vector of Bursaphelenchus xylophilus) have been trapped in Belgium in the period 2013–2022, with 45–95 traps deployed yearly. Based on these data and a species distribution model Grégoire et al. (2026) concluded that the likelihood that Monochamus galloprovincialis is established in Belgium is low. Based on genotyping they concluded that at least some of the beetles caught in Belgium originated from other countries.
In China, the following viruses were reported on symptomatic tomatoes (Solanum lycopersicum) for the first time in Xinjiang province: tomato spotted wilt virus (Orthotospovirus tomatomaculae, TSWV – EPPO A2 List), tomato mottle mosaic virus (Tobamovirus maculatessellati, ToMMV – formerly EPPO Alert List), tomato brown rugose fruit virus (Tobamovirus fructirugosum, ToBRFV – EPPO A2 List), tomato ringspot nepovirus (Nepovirus lycopersici, ToRSV – EPPO A2 List), tomato black ring virus (Nepovirus nigranuli, TBRV – EU RNQP) and tomato chlorosis virus (Crinivirus tomatichlorosis, ToCV – EPPO A2 List). The pathogens were identified by molecular testing (Cao et al., 2026).
- New host plants
The root-knot nematode, Meloidogyne vitis (Nematoda: Meloidogynidae) was recently described from China (Yunnan province) on grapevine (Vitis vinifera) (EPPO RS 2021/027). Yang et al. (2026) have identified a new host plant: M. vitis was identified as damaging Morus alba trees in Yunnan province.
Clary sage (Salvia sclarea) is first recorded as a host plant of Helicoverpa armigera (Lepidoptera: Noctuidae - EPPO A2 List) from field experiments in March to May 2025 in Uttar Pradesh, India (Singh et al., 2026).
In Yunnan Province (China), tomato zonate spot virus (Orthotospovirus tomatozonae, TZSV) was reported on symptomatic kiwifruit (Actinidia chinensis). The virus was identified by molecular testing, however TZSV was only found in one symptomatic sample so further pathogenicity tests are needed (Yin et al., 2026).
In Virginia (USA), in September 2025, Xylella fastidiosa subsp. multiplex (EPPO A2 List) was found infecting poison ivy (Toxicodendron radicans) plants showing leaf scorch symptoms at the edge of a vineyard containing plants known to be infected by X. fastidiosa subsp. multiplex. The pest was identified by molecular testing (Yang et al., 2026).
In Peru, Euplatypus parallelus (Coleoptera: Platypodinae - formerly EPPO Alert List) and Coptoborus ricini (Coleoptera: Scolytinae) were reported to cause mortality to young cacao trees (Theobroma cacao). The pests were identified by morphological and molecular testing (Rojas-Vargas et al., 2026).
