- First records of the lawn bug Blissus insularis Barber (Hemiptera: Blissidae) in EuropePublication . Lima, Arlindo; Valada, Tatiana; Caetano, Maria Filomena; Franco, José Carlos; Ramos, Ana PaulaSince October 2019, chinch bugs have been detected in large sunken dead patches of St. Augustinegrass (Stenotaphrum secundatum) lawns in different locations of Lisbon and Setubal districts, in Portugal. Based on morphological and molecular studies, using mitochondrial Cytochrome C Oxidase subunit I (COI) gene, the collected insects were identified as Blissus insularis (Hemiptera, Heteroptera, Blissidae). This is the first record of this noxious chinch bug species in Europe and in the Palaearctic region
- Melanaspis corticosa: a new insect pest of olive trees in EuropePublication . Mazzeo, Gaetana; Pellizzari, Giuseppina; Mateus, Célia; Silva, Elsa Borges da; Russo, Agatino; Nucifora, Salvatore; Soares, Celestino; Tomé, Dora; Andrade, Eugénia de; Franco, José CarlosThe presence of the South African Obscure Scale, Melanaspis corticosa (Brain) (Hemiptera, Diaspididae), was detected infesting olive trees, in Portugal. The identity of the scale insect was confirmed based on both morphological and molecular studies. Until now, this species was only known in a few African countries, including Guinea, Mozambique, South Africa and Zimbabwe. This is the first record of this species in Europe and in the Palearctic region. The scale was observed in 15 different locations, in the Algarve, since its first detection at the end of 2016. Samples were collected between 21 December 2016 and 10 March 2022, covering all seasonal periods. Most of the sampling sites resulted from private requests from farmers and proprietaries received by the Plant Protection Division of the Regional Directorate of Agriculture. Although it is considered a polyphagous species, it was not observed in other plant species, besides olive trees. The actual dispersion in the region suggests that M. corticosa became established and has been expanded its distribution since its arrival. This scale insect is a potential injurious pest of olive trees and needs to be studied to clarify its pest status and develop effective pest management strategies.
- An annotated checklist of ladybeetle species (Coleoptera, Coccinellidae) of Portugal, including the Azores and Madeira ArchipelagosPublication . Soares, António Onofre; Calado, Hugo Renato; Franco, José Carlos; Aguiar, António Franquinho; Andrade, Miguel M.; Zina, Vera; Ameixa, Olga M.C.C.; Borges, Isabel; Magro, AlexandraA comprehensive annotated checklist of the ladybeetle species of Portugal, including the Azores and Madeira archipelagos, is presented. The Coccinellidae fauna comprises a total of 101 species: 83 from the Mainland, 39 from Madeira, and 32 from the Azores. The listed species are distributed among 2 sub-families and 13 tribes: within the subfamily Microweiseinae, Madeirodulini (1 species), Serangiini (2 species), and within the subfamily Coccinellinae, Azyini (1 species), Chilocorini (4 species), Coccidulini (7 species), Coccinellini (30 species), Epilachnini (4 species), Hyperaspidini (7 species), Noviini (2 species), Platynaspini (1 species), Scymnini (37 species), Stethorini (3 species), and Sticholotidini (2 species). The Portuguese fauna comprises 10 exotic species: 5 present in the Mainland, 7 in Madeira, and 6 in the Azores. Harmonia axyridis (Pallas, 1773) from Madeira, Propylea quatuordecimpunctata (Linnaeus, 1758) from the Azores, Delphastus catalinae (Horn, 1895) from the Azores and Madeira, Nephus (Geminosipho) reunioni (Fürsch, 1974) and Nephus (Nephus) voeltzkowi Weise, 1910 from Madeira and Microserangium sp. from the Mainland, are reported for the first time. Some species are considered doubtful records, as explained in the text. These results were obtained by compiling information on the available literature regarding ladybeetle species on the Portuguese mainland and insular territories, and original data
