Summary: Filth flies are a major pest group in the animal production industry, with parasitic wasps like Spalangia and Muscidifurax being used to manage fly populations. Research showed that S. cameroni may develop resistance to insecticide permethrin, but susceptibility among different strains did not significantly differ. This highlights the potential impact of nontarget insecticide exposure on filth fly parasitoids.

Summary: The house fly and stable fly populations were significantly reduced by 83 to 90% and 66 to 73%, respectively, with the release of 100 predators per square meter. The units where predators were released had much lower numbers of adult flies compared to other units. Provisioning or conserving alternative food sources, such as free-living nematodes, could further enhance biocontrol efficacy for these predatory mites.

Summary: This study investigated the effectiveness of landmark-based geometric morphometrics of wings to discriminate among three morphologically similar species of Stomoxys in Thailand. The results showed that geometric morphometrics can accurately distinguish the three species based on wing shape. Therefore, wing geometric morphometrics can be used along with traditional morphological methods to identify these flies as species.

Summary: This study used mitochondrial gene analysis to reveal the global genetic structure of the bloodsucking fly, Stomoxys calcitrans. The major divergence occurred 0.32-0.47 million years ago, with subsequent diversifications taking place during 0.13-0.27 million years ago. The study suggests that S. calcitrans originated in the Ethiopian region and has non-monophyletic relationships possibly due to ancestral retention, dispersal with mammals, long-distance migration, and the international livestock industries. The study also highlights the potential veterinary importance of three highly diverged Ethiopian lineages.

Summary: The human skin microbiome contributes to mosquito attraction, and we tested if bovine skin microbes affect the attraction of stable flies to bovine hosts. Microbes from a calf and adult cow were isolated and identified. Staphylococcus and bacterial heterogeners attracted flies in both lab and greenhouse experiments, and S. sciuri on agar induced more fly responses than sterile agar in the greenhouse.

Summary: The tolerance of stable fly larvae to water immersion decreases with larval instar, and the developmental time, weight, pupation percentage, adult emergence percentage, and adult weight of survivors are negatively impacted. Specifically, adults developed from first larval instars show better resilience to water immersion stress compared to those developed from second and third larval instars.

Summary: The stable fly, a biting fly, feeds on both blood and plants, as shown by DNA evidence. Nectar supplementation from plants like Parthenium hysterophorus can enhance egg hatchability in stable flies, but does not affect egg laying or longevity. Various plants stable flies feed on have different scents, leading to varied behavioral responses in the flies.

Summary: The study investigated the effects of heat stress and gestational status on ghrelin secretion in Holstein cattle, finding differences in ghrelin levels between seasons and gestation stages. Lower acylated ghrelin levels in summer may explain the reduced feed consumption of heat stressed animals.

Summary: House fly larval grazing significantly altered the abundance and diversity of bacterial, archaeal, and protist communities differently than manure aging alone. Larvae likely adjust community composition by directly feeding on and eliminating microbes, as well as by competing with predatory microbes for nutrients and prey. Overall, larval grazing reduced bacterial and archaeal diversities but increased protist diversity.

Summary: The study developed and evaluated attractant-impregnated adhesive tapes to reduce stable fly attacks on cattle, with significant results. The m-cresol impregnated adhesive tape caught significantly more stable flies in laboratory bioassays. Deploying these tapes in cattle feedlots showed a significant reduction in fly populations, while also relieving cattle stress.

Summary: This study investigated the effects of electric vs virtual fencing on dairy cow behavior and welfare. The results showed that there were no significant differences in milk production, live weight, cortisol concentrations, and activities between the two fencing methods initially. However, in the later stage, cows showed lower activity levels and increased grazing time with the virtual fence compared to the electric fence.

Summary: Based on a neurobiological examination, events around the time of slaughter have the potential to intensify the animal's pain response through processes of sensitisation and enhanced transmission. Despite limited evidence, the analogy with human neurobiology literature suggests a plausible connection, and further dedicated study is needed to confirm the postulated link between events at slaughter and processes of hypersensitisation.

Summary: Allonursing and allosuckling are behaviors displayed by some females, characterized by nursing and feeding non-filial offspring. While they can bring benefits, they can also pose health risks and pathogen transmission. Establishing a close bond between dams and newborns is essential for providing protection and nutrition, but these behaviors may have implications on animal welfare.

Summary: Animal welfare is the result of meeting animals' physiological and psychological needs, allowing them to be free from hunger, discomfort, pain, fear, and distress. Understanding the neurobiology of behavior and well-being can help us achieve better animal welfare by ensuring animals' basic needs are met and their innate and learned responses are considered.

Summary: This article examines the physiological role of pain during parturition in domestic animals and discusses the controversies surrounding the use of opioids, non-steroidal anti-inflammatory drugs (NSAIDs), and local analgesics as treatments during labor. The use of analgesics during labor can have both advantages and disadvantages for the mother and offspring, and managing pain during this process requires understanding the properties of different analgesics.

Summary: The objective of this study was to determine the presence of toxigenic fungi Aspergillus spp. and Fusarium spp. in domestic flies from dairy farms. Flies were collected from 10 dairy farms in Aguascalientes, Mexico. The fungi were cultured and identified, and the production capacity of aflatoxins and zearalenone was quantified. The results showed that the flies were present in all capture sites and that some isolates of Aspergillus spp. and Fusarium spp. produced aflatoxins and zearalenone, respectively.
