(Hymenoptera, Tenthredinidae) – a New Pest Species of Ash Tree in the Republic of Moldova
Muzeul Olteniei Craiova. Oltenia. Studii şi comunicări. Ştiinţele Naturii. Tom. 36, No. 1/2020 ISSN 1454-6914 Tomostethus nigritus F. (HYMENOPTERA, TENTHREDINIDAE) – A NEW PEST SPECIES OF ASH TREE IN THE REPUBLIC OF MOLDOVA MOCREAC Nadejda Abstract. In the Republic of Moldova, the ash tree is a common forest species, used in the reforestation and afforestation of woods and territories, and widely used as an ornamental tree in cities and along roads. For more than ten years, our ash tree woods have been severely defoliated by the ash weevil Stereonychusfraxini (De Geer, 1775) from Curculionidae family. In the vegetation period of 2018 and 2019, defoliation was seen on ash trees, caused by unknown sawfly larvae species from the Tenthredinidae family. The analyses showed that these pests belong to the Hymenoptera order – the privet sawfly – Macrophya punctumalbum (Linnaeus, 1767), and Tomostethus nigritus (Fabricius, 1804), the last one being a new species for the fauna of the Republic of Moldova. The biggest ash defoliations caused by the Tomostethus nigritus larvae were recorded in the centre of the country, especially in the Nisporeni and Tighina Forest Enterprises and in the “Plaiul Fagului” Scientific Reserve, as well as in the urban space. Keywords: Ash Black sawfly, Tenthredinidae, ash tree, outbreaks, defoliations, Republic of Moldova. Rezumat. Tomostethus nigritus F. (Hymenoptera, Tenthredinidae) – specie nouă de dăunător al frasinului în Republica Moldova. În Republica Moldova, frasinul este o specie obișnuită, folosită nu numai în reîmpădurire și împădurire dar utilizat pe scară largă ca arbore ornamental în parcurile din orașe și de-a lungul drumurilor. Mai bine de zece ani, pădurile de frasin sunt defoliate anual de către trombarul frunzelor de frasin Stereonychus fraxini (De Geer, 1775) din familia Curculionidae. -

Investigations into the declining health of alder (Alnus glutinosa) along the river Lagan in Belfast, including the first report of Phytophthora lacustris causing disease of Alnus in Northern Ireland Richard O Hanlon (1, 2)* Julia Wilson (2), Deborah Cox (1) (1) Agri-Food and Biosciences Institute, Belfast, BT9 5PX, Northern Ireland, UK.

Abstract Common alder (Alnus glutinosa) is an important tree species, especially in riparian and wet habitats. Alder is very common across Ireland and Northern Ireland, and provides a wide range of ecosystem services. Surveys along the river Lagan in Belfast, Northern Ireland led to the detection of several diseased Alnus trees. As it is known that Alnus suffers from a Phytophthora induced decline, this research set out to identify the presence and scale of the risk to Alnus health from Phytophthora and other closely related oomycetes. Sampling and a combination of morphological and molecular testing of symptomatic plant material and river baits identified the presence of several Phytophthora species, including Phytophthora lacustris. A survey of the tree vegetation along an 8.5 km stretch of the river revealed that of the 166 Alnus trees counted, 28 were severely defoliated/diseased and 9 were dead. -

Journal of Hymenoptera Research 72: 67–81. https://doi.org/10.3897/ jhr.72.38284 Abstract In Western Europe the ash sawflyTomostethus nigritus is known to occur at low densities on Fraxinus excelsior and is uncommonly reported as a pest species. However, we show here that outbreaks can oc- cur on non-endemic trees such as F. angustifolia, and that the species is able to spread quickly using city infrastructure. At the visited localities near the city of Ghent, foliage of Fraxinus angustifolia ‘Raywood’ emerged approximately one month earlier than on F. excelsior. At the same time, changed climatic condi- tions in the last decade, i.e. higher temperatures in March, caused adults to emerge earlier. Synchronic- ity of the potential hosts and T. nigritus may therefore have altered, playing a crucial role in population dynamics. Future research should aim to confirm if the species dramatically declines in numbers after reaching its peak population level, an effect which was observed in previous studies, but for which there is still no satisfactory explanation. -

L3 3AF, UK. 11 Abstract 12 Trees provide key ecosystem services, but the health and sustainability of these plants is 13 under increasing biotic and abiotic threat, including from the growing incidences of non- 14 native invasive plant pests (including pathogens). The island of Ireland (Ireland and Northern 15 Ireland) is generally accepted to have a high plant health status, in part due to its island status 16 and because of the national and international regulations aimed at protecting plant health. To 17 establish a baseline of the current pest threats to tree health for the island of Ireland, the 18 literature and unpublished sources were reviewed to produce a dataset of pests of trees on the 19 island of Ireland. The dataset contains 396 records of pests of trees on the island of Ireland, 20 the majority of pests being arthropods and fungi, and indicating potentially more than 44 non- 21 native pest introductions. -
