Santa Catarina is an important tomato‐producing state in Brazil, but there is little data regarding the prevalence and characterization of viruses and insect vectors in tomato plants in this state. This study surveyed viruses and their vectors in commercial tomato‐producing areas, as well as alternative hosts and weeds in the surrounding areas. Sixty‐five samples of young leaves were collected between 2019 and 2023, and viruses were detected with generic or specific PCR primers targeting several virus genera. In addition, 397 virus vector insect samples were collected and identified. The orthotospoviruses tomato chlorotic spot virus (TCSV) and groundnut ringspot virus (GRSV) were the most prevalent and distributed in several regions, whilst the crinivirus tomato chlorosis virus (ToCV) and begomovirus tomato severe rugose virus (ToSRV) were restricted to the metropolitan region of Florianópolis. This is the first report of ToSRV in Solanum americanum in Brazil and of TCSV in zucchini and cucumbers worldwide. A survey of insect vectors found whiteflies, Mediterranean cryptic species of Bemisia tabaci (MED) and Trialeurodes vaporariorum were predominant, while Frankliniella occidentalis and F. schultzei thrips were often found cohabiting in the sampled crops. These results highlight the need to adapt management strategies in Santa Catarina, especially in the Santo Amaro da Imperatriz region, where a greater frequency and diversity of viral species and vectors were found. In addition, both the thrips and whitefly species (especially MED) found are a cause for concern, as they readily transmit viruses that infest crops in the open fields of Santa Catarina.

“…Most of the adult specimens were identified under a stereoscopic microscope with an 80 x magnification. Some specimens of each species were mounted on microscopic slides following the Mound and Marullo technique (12) and identified by keys and descriptions (1,4,7,8,9,14) or by confrontation with previously identified material from the thrips collections of INTA Mendoza (EEA Mza INTA) and of the Museo de Ciencias Naturales de La Plata (MLP https:// www.museo.fcnym.unlp.edu.ar/). All specimens collected were preserved in vials with 70% ethanol or microscopic slides at the Entomology Lab of the EEA Mendoza INTA.…”

The presence of the “pear thrips” Taeniothrips inconsequens has been cited in Argentina in 1921 by Teresa Joan. This has affected exports of fruit tree propagation materials. However currently there is a concern about that citation because it was probably an incorrect identification of the thrips species. The objective of this work was to confirm the presence of Taeniothrips inconsequens in fruit orchards in Argentina. Fruit orchards were sampled in the main producing areas of Argentina. A total of 10,696 specimens from 393 samples were examined and no T. inconsequens were found. The citation of this species for Argentina could be the result of misidentifications. Ninety percent of the collected specimens corresponded to four species of thrips: 37% Frankliniella australis, 29% Thrips tabaci, 14% Frankliniella occidentalis and 10% Frankliniella gemina. Of the remaining 10%, 2% were larvae and 8% corresponded to the species Aneristothrips rostratus, Frankliniella frumenti, Frankliniella schultzei, Frankliniella inesae, Frankliniella juancarlosi, Frankliniella spp, Leptothrips mali, Aeolothrips fasciatipennis, Arorathrips texanus, Tenothrips frici, Haplothrips spp, Haplothrips fiebrigi, Haplothrips trellesi, Thrips australis, Karnyothrips spp., and Caliothrips phaseoli. Highlights Taeniothrips inconsequens was not found in Argentina. No slides of specimens collected in Argentina of inconsequens were found at the Museo de La Plata. Frankliniella gemina was dominant in Buenos Aires, Thrips tabaci in Mendoza, Haplothrips in Río Negro and Neuquén, Frankliniella occidentalis in Chubut and Santa Cruz, and Farnkliniella australis Morgan in San Juan. Frankliniella australis was dominant in almond and peach trees, while Thrips tabaci was dominant in pear and quince trees.

“…The three most important pests of this genus are Frankliniella occidentalis (Pergande), Frankliniella gemina Bagnall, and Frankliniella schuilzei Trybom (Alejo & Zamar, 2021; De Borbón et al., 2006). Frankliniella gemina is a Neotropical endemic species broadly distributed from Mexico to Argentina (Borbón & Zamar, 2018; Cavalleri & Mound, 2012). It is considered a polyphagous pest due to the wide variety of host plants attacked, such as fruit, vegetable, and other crops, as well as weeds, such as Conium maculatum L. (Apiaceae), which is a continentally distributed spontaneous plant species, ranging from the USA to Argentina, frequently found surrounding crops; this weed hosts high densities of F. gemina (Maza, Contino, et al., 2022; Gulezian et al., 2012; Riley et al., 2011; Zamar, 2011).…”

Fruit and vegetable crops are affected by numerous arthropods, including aphids and thrips. Hoverfly adults are important pollinators, and their larvae are mainly aphid predators. Molecular studies on the stomach contents of larvae allowed to associate hoverflies with the consumption of other soft‐bodied arthropods, including thrips, with few records found in Neotropical hoverfly species. Allograpta exotica (Wiedemann) (Diptera: Syrphidae), a species widely distributed in the Americas, from the USA to Argentinian Patagonia, has been associated with numerous crops mainly affected by aphids, and to a lesser extent with whiteflies. The objective of this work was to assess the consumption and preference rates of various instars of A. exotica as biocontrol agents for two major insect pests, Myzus persicae (Sulzer) (Hemiptera: Aphididae) and Frankliniella gemina (Bagnall) (Thysanoptera: Thripidae), under controlled laboratory conditions. Additionally, we morphologically characterized the three larval stages of A. exotica. We determined that all three instars of A. exotica consume both M. persicae and F. gemina, and that they kill more thrips than aphids. Still, A. exotica preferred M. persicae over F. gemina, even when the relative aphid availability decreased compared to F. gemina, although consumption of both prey types remained high. Interestingly, A. exotica second instars consumed four times more thrips than aphids. This study explored the potential use of one of the most common hoverfly species in fruit and vegetable crops as a biocontrol agent of aphids and thrips. Further laboratory and field studies should explore more deeply the potential of this Neotropical beneficial dipteran.
