“…Megaphragna priesneri Timberlake (Hymenoptera: Trichogrammatidae) was found parasitising the eggs of R. syriacus in Egypt and Israel (Polaszek et al., 2022 ). Thripobius hirticornis Ferrière and Thripoctenus javae Girault (Hymenoptera: Eulophidae) parasitise the larvae of R. syriacus and can efficiently control the pest populations on Bucida buceras and Lagestroemia speciosa (Etienne et al., 2015 ).…”

Following a request from the European Commission, the EFSA Panel on Plant Health performed a quantitative risk assessment for the EU of Retithrips syriacus (Mayet) (Thysanoptera: Thripidae), a polyphagous thrips, regarded as a tropical/ subtropical pest occurring in several countries of Africa, South America, Asia and in the EU in Cyprus. The current risk assessment focused on potential pathways for entry, the climatic conditions allowing establishment, the expected spread capacity and the impact considering a time horizon of 10 years (2023)(2024)(2025)(2026)(2027)(2028)(2029)(2030)(2031)(2032). The Panel identified the import of cut roses, persimmons, table grapes, as well as plants for planting of the genera Acalypha and Terminalia from third countries and those of Persea americana (avocado) from Israel as the most relevant entry pathways to consider. Over the next 10 years, an annual median estimate of 95 (90% Certainty Range, CR, ranging from 13 to 1832) potential R. syriacus founder populations per year are expected to successfully transfer to a suitable host in the EU NUTS2 regions where the climatic conditions are predicted as suitable for establishment; this value drops to a median of 4.6 founder populations per year (90% CR: 1 every 1.9 years -85.6 per year) after considering the actual probability of establishment of a potential founder population. The estimated number of founder population per year is mostly driven by the import of cut roses and plants for planting. If such founder populations were to establish, R. syriacus is estimated to spread at a median rate of 0.05 km/year (90% CR 0.02-2.30 km/year) after a median lag phase of 1.1 years (90% CR 0.3-3.3 years). The overall impact on yield (expressed as % of the total agricultural production) directly attributable to R. syriacus when considering: (i) the main R. syriacus hosts in the EU, (ii) the areas of the EU where establishment is possible, (iii) the current agricultural practices and (iv) the evidence of impact from the countries where the pest is established for a long time, was estimated at 0.065% as the median value of the uncertainty distribution (90% CR 0.001%-0.571%). Options for risk reduction are discussed, but the effectiveness was not quantified.

“…Primer sequences for each genomic region are listed in Table 1. The thermocycling conditions for the 28S-D2-3 region followed Andreason et al (2019) and that of COI followed Fusu and Polaszek (2017) and Polaszek et al (2022). PCR amplicons were visualized on a 1.5% agarose gel in 1X TAE buffer stained with SYBR Safe DNA Gel Stain (Invitrogen, Carlsbad, CA, USA) and a TrackIT 1 Kb Plus DNA Ladder (Invitrogen, Waltham, MA, USA) to estimate product sizes.…”

A new, biparental species of the genus Encarsia Förster (Hymenoptera: Aphelinidae), E. hera Lahey & Andreason, sp. nov., is characterized based on morphological and molecular data. The parasitoid was reared from the puparia of its host, an undescribed species of the grass-feeding aleyrodine genus Aleurocybotus Quaintance & Baker (Hemiptera: Aleyrodidae) collected in Gainesville, Florida. The same whitefly is newly recorded from Charleston, South Carolina, where it is a pest of ornamental Muhly grass [Muhlenbergia capillaris (Lam.) Trin. (Poaceae)]. A phylogenetic analysis based on a fragment of 28S ribosomal DNA in 34 Encarsia species placed E. hera, sp. nov., within the E. luteola-group, a result concordant with its morphology. A key to the Encarsia species reared from Aleurocybotus is provided.

“…In this case we can presume that the trade routes can be a way for the introduction of new species in the country, especially a species with specimens that are so reduced in size. There are other examples of introduced species of hymenopterans by human mediated transportation, frequently with the transportation of their hosts (Fusu 2017;Polaszek et al 2022;Rasplus et al 2010). Also, Popovici et al (2018) formulated some hypotheses concerning the modality of introducing microhymenopteran species to a wide geographical area based on examples from Platygastroidea.…”

After the presence of the genus Platyscelio was noticed and confirmed in the Neotropical realm, in this paper the genus is recorded from the Panamanian realm, in Dominican Republic. In the Neotropical realm Platyscelio is represented through P. africanus Risbec, previously considered as being present only in the Afrotropical realm, but in the Panamanian realm we found a different species – P. pulchricornis Kieffer.
