A total of 257 mammals, including rodents, opossums, dogs and cats, were examined to detect the presence of <i>Bartonella</i> in both fleas and host tissues. The study revealed the presence of <i>Bartonella</i> in rodent fleas (47.7%), opossum fleas (7.8%), rodent spleens (6.5%) and cat blood (10%). Analysis of 15 <i>gltA</i> gene fragments revealed the existence of at least three different genotypes and eight haplotypes. Genetic analysis has established a close association between <i>Bartonella</i> species from mammals and fleas in both the Atlantic Forest of Brazil and the Costanera Sur Reserve in Argentina. <i>Bartonella henselae</i> (Regnery et al.) Brenner et al.

This marks the first report of <i>B. henselae</i> in <i>R. rattus</i> in Argentina, as well as the initial documentation of its association with <i>A. montensis</i> and <i>C. tener</i>. Additionally, <i>Bartonella clarridgeiae</i> Lawson and Collins (Hyphomicrobiales: Bartonellaceae) was identified in feline blood and in fleas from dogs and cats. These findings are particularly relevant in the context of areas undergoing deforestation, where interactions between wild and domestic hosts increase the risk of zoonotic disease transmission.

Our study aims to uncover the intricate relationships between the main mosquito vector of these viruses, <i>Culex pipiens</i> L.

We estimated the bird host potential to act as a host for flavivirus, the reservoir capacity index, based on forage ratios and potential host competence based on molecular prevalence. We sampled mosquitoes and, at the same time, conducted bird censuses in the Camargue region in southern France, where co-circulation of these viruses has been reported. Several localities were sampled along a land-use gradient in peri-urban, agricultural and natural areas from May to November 2021. We identified 55 vertebrate species in 110 engorged <i>Cx. pipiens</i> by PCR amplification and sequencing of mitochondrial 12S and 16S Ribosomal DNA genes. <i>Culex pipiens</i> feeds primarily on 51 bird species and secondarily on two mammals, one amphibian and one reptile.

Both the frequency and intensity of climate-related adverse weather events are predicted to increase, likely resulting in changes to vector dynamics and vector–human interactions, leading to an increased risk of disease transmission. Yet, a gap exists in our knowledge of the impact of these events on hygiene and associated pest-borne diseases. A growing body of research connects two groups of pests (domestic flies and cockroaches) that are linked with poor hygiene and sanitary conditions to mechanical disease transmission. We present a review of these specific vectors' population biology and behaviour, links with hygiene and sanitation and how pest populations and public health could be affected by adverse weather events. There is evidence that increased temperatures, extreme rainfall and flooding events are most likely to be associated with increased fly and cockroach populations and changes in the behaviour or activity of these insects, which could exacerbate the risks of disease transmission. Warmer temperatures accelerate their rates of reproduction, while heavy rainfall and flooding disrupt their habitats, driving them indoors. Other factors like habitat destruction, breakdown in healthcare system infrastructure, population displacement and altered pesticide use following an extreme weather event are predicted to influence insect populations and provide opportunities for increased human –pest contact.

They have recently been shown to also develop in brackish water in coastal areas. Previous findings showed that Ae. aegypti larvae developing in brackish water possessed thicker cuticles and greater larvicide resistance than larvae developing in fresh water. The present study compared cuticle ultrastructure, resistance to adulticides, and the activities of adulticide detoxifying enzymes in female mosquitoes emerging from fresh and brackish water-developing Ae. aegypti preimaginal stages. The results showed that brackish water-derived females possessed significantly thicker tarsal and abdominal cuticles compared to fresh water-derived females. Brackish water-derived Ae. aegypti females were also significantly more resistant to three different types of pyrethroids and malathion compared to fresh water-derived females. Corresponding reversal of cuticle changes and adulticide resistance when preimaginal salinity was reversed showed that preimaginal salinity determined both procuticle structure and adulticide resistance in brackish water-derived females. Compared with fresh water-derived Ae. aegypti females, brackish water-derived females had similar activities of the adulticide-detoxifying enzyme families of esterases and glutathione S-transferases and a modest increase in the activity of monooxygenases, all of which were lower than the threshold values attributed to resistance in field populations of Ae. aegypti. Reduced permeability of the thicker and remodelled cuticles in brackish water-derived Ae. aegypti females to adulticides is proposed to be mainly responsible for their greater resistance to different types of adulticides. Greater salinity tolerance of preimaginal stages, adult cuticle changes and higher larvicide and adulticide resistance are inherited properties of brackish water-developing Ae. aegypti that reverse in a few generations after transfer to fresh water. This is compatible with a role for epigenetic changes in the adaptation of Ae. aegypti to brackish water. Greater resistance of salinity-tolerant Ae. aegypti to adulticides and larvicides poses a hitherto unappreciated problem for controlling arboviral diseases, with attendant implications also for other mosquito-borne diseases.</p>","PeriodicalId":18350,"journal":{"name":"Medical and Veterinary Entomology","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143573155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mosquitoes were collected using a battery-powered handheld aspirator every 2 months between November 2021 and April 2022 in temperate Argentina. Blood-engorged mosquitoes were collected at 11 sites corresponding to five types of settings: two cattle fields, one rabbit breeding farm, three chicken farms, two dog boarding facilities, and three geriatric hospitals, characterised by the permanent overabundance of cows, rabbits, chickens, dogs, and humans, respectively.

A principal component analysis (PCA) was performed in which variables were pairs comprising an engorged mosquito species and the host species it fed on. A total of 242 blood meals from <i>Aedes</i> (3 species), <i>Culex</i> (4), <i>Isostomyia</i> (1) and <i>Psorophora</i> (1) were identified.

However, over time the reluctance of legal professionals to allow entomological evidence into a court of law has waned, and currently, entomological evidence is accepted in many countries as part of criminal proceedings (Du Plessis &amp; Meintjes-Van der Walt, &lt;span&gt;2004&lt;/span&gt;; Hall, &lt;span&gt;2021&lt;/span&gt;). With the advancement of scientific techniques and technologies, and the introduction of artificial intelligence (AI) tools, it is paramount that the scientific community is constantly evolving and developing novel methods to analyse entomological samples.&lt;/p&gt;&lt;p&gt;The development of forensic entomology accelerated in the twentieth century with advancements in biology and technology. Researchers began to catalogue the predictable patterns of insect colonization on corpses (Anderson &amp; VanLaerhoven, &lt;span&gt;1996&lt;/span&gt;; Eberhardt &amp; Elliot, &lt;span&gt;2008&lt;/span&gt;), noting how environmental factors such as temperature influence insect activity and development. Studying the influence of temperature on the developmental rates of necrophagous insect species is pivotal for enabling their reliable use as forensic indicators (Amendt et al., &lt;span&gt;2010&lt;/span&gt;); however, the effect of suboptimal temperatures and their potential casework implications remain as relevant topics that deserve further investigation (López-García &amp; Martín-Vega, &lt;span&gt;2025&lt;/span&gt;). The potential effect of other abiotic factors on insect biology is another aspect that needs further study in order to strengthen the reliability of the interpretation of entomological evidence in forensic investigations (Ferreira et al., &lt;span&gt;2025&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;In recent decades, forensic entomology has embraced cutting-edge technologies and interdisciplinary approaches. DNA barcoding and similar molecular techniques allow rapid and precise identification of insect species (Durango-Manrique et al., &lt;span&gt;2025&lt;/span&gt;), which is essential for a reliable analysis and interpretation of entomological evidence. Nonetheless, morphological descriptions of the different life stages can also provide powerful tools for the unequivocal identification of forensically relevant species (Grella et al., &lt;span&gt;2025&lt;/span&gt;; Martínez-Sánchez et al., &lt;span&gt;2024&lt;/span&gt;). Additionally, advances in stable isotope analysis enable investigators to trace the geographic origin of insects (Owings et al., &lt;span&gt;2021&lt;/span&gt;), further narrowing the location of death or body transport. High-resolution imaging and AI also have enhanced the accuracy and efficiency of insect identificat","PeriodicalId":18350,"journal":{"name":"Medical and Veterinary Entomology","volume":"39 1","pages":"1-2"},"PeriodicalIF":1.9,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/mve.12792","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143111762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
