Establishment of Sinoxylon anale Lesne (Coleoptera, Bostrichidae) in Brazil: Identification, Host Plants, Distribution, and Damage.

Damage from Sinoxylon anale Lesne, a woodboring beetle not previously known to be established in Brazil, was observed in young jabuticaba trees (Plinia cauliflora, Myrtaceae) in a nursery in the municipality of Laranjal Paulista, state of São Paulo. We immediately advised MAPA ("Ministério da Agricultura, Pecuária e Abastecimento") and collected samples from the nursery and from different hosts in nearby areas, to identify the specimens and investigate the dynamics of the infestation in the jabuticaba trees. Sinoxylon anale was also collected in ethanol-baited and ultraviolet-light traps and in dry branches of the native species pau-jacaré (Piptadenia gonoacantha, Fabaceae) and inga (Inga vera, Fabaceae), and the exotic pau-d'água (Dracaena fragrans, Asparagaceae) in the municipality of Piracicaba, state of São Paulo. These collections established that S. anale larvae and adults develop in dead branches of four new host plants. Taxonomic studies using morphological parameters and DNA barcoding confirmed the identification of S. anale. An illustrated key to the three Sinoxylon species now recorded in Brazil is provided, and the COI gene sequences have been made available in a public database. Sinoxylon anale probably attacked the young jabuticaba trees after they were killed by larvae of long-horned beetles (Cerambycidae). So far, S. anale has been found established only in two locations in the same area of the state of São Paulo.

A Decade of Hidden Phytoplasmas Unveiled Through Citizen Science.

Climate change is impacting agriculture in many ways, and a contribution from all is required to reduce the imminent losses related to it. Recently, it has been shown that citizen science could be a way to trace the impact of climate change. However, how can citizen science be applied in plant pathology? Here, using as an example a decade of phytoplasma-related diseases reported by growers, agronomists, and citizens in general, and confirmed by a government laboratory, we explored how to better value plant pathogen monitoring data. Through this collaboration, we found that in the last decade, 34 hosts have been affected by phytoplasmas; 9, 13, and 5 of these plants were, for the first time, reported phytoplasma hosts in eastern Canada, all of Canada, and worldwide, respectively. Another finding of great impact is the first report of a 'Candidatus Phytoplasma phoenicium'-related strain in Canada, while 'Ca. P. pruni' and 'Ca. P. pyri' were reported for the first time in eastern Canada. These findings will have a great impact on the management of phytoplasmas and their insect vectors. Using these insect-vectored bacterial pathogens, we show the need for new strategies that can allow fast and accurate communication between concerned citizens and those institutions confirming their observations.[Formula: see text] Copyright © 2023 The Author(s).

Description of two new species of Ectinorus (Ectinorus) (Siphonaptera, Rhopalopsyllidae) from Argentina, including a morphometric approach.

Two new species of fleas of genus Ectinorus (Siphonaptera: Rhopalopsyllidae) are described from sigmodontine rodents (Rodentia: Cricetidae) collected during a survey of small mammals in northwestern Argentina.The new species belong to the subgenus Ectinorus and can be distinguished from all other species of the subgenus by the characteristics of the modified abdominal segments and by the genitalia. Moreover, the male of Ectinorus (Ectinorus) disjugis is described for the first time and the finding of this flea parasitizing the rodent Akodon spegazzinii, constitutes a new flea-host association. A phylogenetic analysis of the genus Ectinorus, using traditional morphological characters and morphogeometric data, is presented to support the erection of the new species of Ectinorus. An identification key for all species of Ectinorus is also provided. Our study increases to 38 the total number of species of the subgenus Ectinorus, and to 20 the number for Argentina. Phylogenetic analyses reveal that Ectinorus is monophyletic but the subgenera are not. This study offers a new interpretation of morphological diversity within the genus as well as an evaluation of hypotheses about their relationships.

Wildlife species, Ixodid fauna and new host records for ticks in an Amazon forest area, Rondônia, Brazil / Espécies de vida selvagem, fauna ixodídica e novos registros de hospedeiros de carrapatos em uma área de Floresta Amazônica, Rondônia, Brasil

Abstract The objective of this work was to evaluate the diversity of ticks associated with free-living animals and to investigate new host records for ticks. Ticks were collected from animals rescued during the flood of the Jamari River in the municipality of Ariquemes, state of Rondônia, North Region of Brazil. A total of 39 animals were captured, out of which 10 were amphibians, 19 were reptiles and 10 were mammals. A total of 127 ticks of the Amblyomma genus were collected from these animals, distributed among seven species: Amblyomma dissimile, Amblyomma geayi, Amblyomma humerale , Amblyomma longirostre, Amblyomma nodosum , Amblyomma rotundatum and Amblyomma varium. In addition, one specimen of Rhipicephalus (Boophilus) microplus was collected. Among these specimens, 85 were adults and 42 were nymphs, with A. rotundatum being the most prevalent species. An Amblyomma spp. larvae was also collected from a lizard (Uranoscodon superciliosus), and one Amblyomma calcaratum and one Amblyomma dubitatum were recovered from the environment, thus totaling 130 ticks. Among the Ixodidae collected from different hosts, we provide the first report for the species A. rotundatum parasitizing Rhinella major, U. superciliosus, Leptophis ahaetulla, Chironius multiventris, and Mastigodryas boddaerti, as well as of A. humerale parasitizing U. superciliosus, A. geayi parasitizing Choloepus didactylus, and Rhipicephalus (B.) microplus parasitizing Alouatta puruensis.
