A research team at Emory University has found that mild head injuries in early life can lead to neurodegenerative conditions later in life, particularly in females. Using fruit flies as a model, the researchers discovered that chronic immune suppression after mating makes female fruit flies more susceptible to brain deterioration following head injuries. The study highlights the importance of understanding the sex-dependent responses to traumatic brain injury and the potential impact of age on injury outcomes. Further research is needed to determine if similar processes occur in other species. [Extracted from the article]

For many organisms, habitat avoidance provides the first line of defence against parasitic infection. Changes in infection status can shift the cost-benefit ratio of remaining in a given habitat vs dispersing. The aim of this study was to test the hypothesis that the propensity to disperse in Drosophila nigrospiracula is mediated by current parasite load and the risk of further infection by an ectoparasitic mite (Macrocheles subbadius). An activity monitor was used to assess dispersal propensity among infected and uninfected flies. The activity level of uninfected females increased threefold upon exposure to a mite, whereas the activity among uninfected males increased by 17-fold in the presence of a questing mite. Among infected flies, the risk of further infection also generated a change in activity, but the magnitude of the response was dependent on host sex. Current infection status influenced the probability of acquiring more parasites due to increased susceptibility to infection with mite load. The probability of acquiring additional mites among males increased more rapidly compared to female flies. Current infection status can potentially determine the risk of further infection, the host propensity and ability to disperse, with consequence for hosts and parasites at the individual, population and species level.

The article presents the negative economic impact of flies on dairies. Topics include all flies passing through four life stages such as egg, larva (maggot), pupa, and adult; stable flies developing as maggots about any decomposing organic matter containing soiled bedding and feed debris; and horn flies and face flies developing in fresh cattle manure which being a serious problem in pastured herds.

This article discusses a study on the developmental outcomes of the acoustic parasitoid fly Ormia ochracea. The fly's larval young rely on nutritional resources within host crickets for growth and development. The study aimed to understand the effects of host size and resource competition on the fly's development. The researchers found that host cricket size did not affect pupation or eclosion success, but resource competition between larvae negatively impacted these outcomes and resulted in smaller pupae. The study concludes that resource competition among developing parasitoids can have a negative effect on developmental outcomes. [Extracted from the article]

Flies can have a significant impact on cattle, affecting weaning and lactation rates, causing stress, and spreading disease. The most common types of flies found on farms in the Northern Plains are stable flies, houseflies, face flies, and horn flies. Stable flies and houseflies are considered premise flies and are found in confined areas like barns, while horn flies and face flies are pasture flies and are often seen outside of confined spaces. Effective fly control involves sanitation, monitoring for signs of flies, and using a mix of management tools such as sprays, ear tags, back rubbers, and biological options.

Male fruit flies have a complex courtship behavior that involves vibrating their wings to produce a distinctive song to attract females. Researchers at Howard Hughes Medical Institute's Janelia Research Campus have used novel tools, including a custom-built fly recording studio, to identify the group of neurons in the fly's nerve cord that produce and pattern these courtship songs. They have also measured neuronal activity in these cells to understand how they control each type of song. This research provides valuable insights into how the fly nervous system coordinates complex social behaviors and generates multiple movements, which could have implications for understanding similar behaviors in other animals, including humans.

On a cold March night last year in Portsmouth, England, an entirely new type of aircraft flew for the first time, along a dimly lit 120-meter corridor in a cavernous building once used to build minesweepers for the Royal Navy. • This is the Phoenix, an uncrewed blimp that has no engines but propels itself forward by varying its buoyancy and its orientation. The prototype measures 15 meters in length, 10.5 meters in wingspan, and when fully loaded weighs 150 kilograms (330 pounds). It flew over the full length of the building, each flight requiring it to undulate up and down about five times. [ABSTRACT FROM AUTHOR]

Turns out, the ratio of three forms of hydrogen in the atmosphere shifts with latitude, a clue that allowed the dragonfly researchers to piece together the green darner's three-generation migration life cycle. One of 3,000- plus dragonfly species today, the green darner's massive, multifaceted eyes and maneuverable sets of wings allow it to easily track and ambush prey in midair. Netting out pond debris can disturb dragonfly eggs, and leaf litter on the bottom gives aquatic dragonfly nymphs a place to hide and hunt. [Extracted from the article]

As a GSI Machine & Fabrication dealer under his Chucksee brand, it was a no-brainer to use one of the company's latest offerings - a complete, custom, laser-cut air ride-equipped chassis made specifically for '55-59 GM trucks! As "vintage" as the exterior of the truck looks, Chuck wanted the engine compartment to be just as clean as the spotless chassis. In total, it took Chuck just over 11 months to finish the truck, and when asked how much it cost to build the truck, he simply replied, "Eight quarts of sweat!". [Extracted from the article]

The Stradale effectively notifies every automaker and race team that, if you want complex carbon parts built to the highest standard, Dallara can do it faster and better and cheaper than you. He made the striking statement that the Stradale was "a marketing-free exercise", which sounds like code for "this carbon rocket is punching a Stradale-sized hole in Signore Dallara's pocket". But unlike sports-car loss leaders at other companies, the Stradale can't lend cachet to a struggling crossover; Dallara doesn't make any other road cars. The Dallara is nowhere near that velocity here, but Guarnaccia says the Stradale's wing develops appreciable downforce even at low speed. [Extracted from the article]

Objective. To identify studies on the competence of Culex mosquitoes as vectors for the transmission of Zika virus (ZIKV) around the globe. Methods. We performed an integrative review to identify relevant articles on specific experiments to determine whether Culex mosquitoes are vectors for ZIKV. The sources we used for our research were the Brazilian Periódicos CAPES electronic portal (MEDLINE/PubMed, ScienceDirect Journals, Nature Publishing Group, SciELO, Springer Link, and 250 other databases) and gray literature. Results. We identified 344 studies, of which 36 were considered for this review. In 8 studies, infection in salivary glands of Culex quinquefasciatus, Culex restuans, Culex tarsalis, and Culex coronator was detected. Cx. quinquefasciatus was the most studied among those confirmed as potential ZIKV vectors, and only strains of Asian lineages (THA/2014/SV0127-14; SZ01 (2016)) and American lineages (BRPE243 (2015); PRVABC59 (2015)) can infect the salivary glands of Culex mosquitoes. The tested African strains (MR766 and DAK AR 41525) were unable to infect salivary glands. Conclusions. There is still a lack of compelling evidence that indicates Culex spp. are a competent ZIKV vector, but they should remain a target for further monitoring studies, especially regarding ZIKV transmission to other species. Furthermore, studies should not be limited to studying whether their salivary glands are infected. [ABSTRACT FROM AUTHOR]

Beginning with concepts formed by University of Oxford neuroscientist Sir Charles Scott Sherrington that ultimately led to the creation of optogenetics, the author describes how the technology has been developed. Also discussed are the initial trials of this technology in flies. INSETS: MAKING SENSE OF CIRCUITS;THERAPEUTIC POTENTIAL.

A recent study conducted by researchers at the College of Veterinary Medicine in Ethiopia examined the prevalence of biting flies and associated pathogens in camels in the Amibara district. The study found that 87% of camels were infested with biting flies, and 18% were infected with Trypanosoma evansi, a parasite that can cause significant economic losses in the pastoralist community. The most prevalent biting fly species were Hippobosca, Stomoxys, and Tabanus. The study also found that age, body condition score, and season had a significant effect on the prevalence of biting flies and T. evansi. The researchers recommend strategic acaricide application, proper antiprotozoal drug use, and raising awareness about acaricide use to prevent and control biting fly infestation.

A preliminary study conducted by researchers at King Mongkut's Institute of Technology Ladkrabang in Thailand investigated the prevalence of hemoprotozoan parasites in Stomoxys and tabanid flies found in horse farms. The researchers used conventional polymerase chain reaction (PCR) and DNA sequencing to identify the species of parasites present in the flies. Out of the 189 biting flies collected, 10 samples were positive for the 18S rRNA gene of the parasites. The study found a variety of parasites in the flies, suggesting that they can be used to confirm the presence of hemoprotozoan parasites in the study area. The researchers concluded that understanding the presence of these parasites in flies could help in designing vector control programs and managing diseases in the area. [Extracted from the article]

In October 1995, a white rhino, recently arrived in England from South Africa, excreted an insect larva in its dung. Concerned about what this maggot was doing inside their endangered animal, the rhino's new owners called in entomologist Martin Hall of the Natural History Museum in London to have a look. The breakthrough for the world's endangered parasites came last year when a genomics corporation called Diversa Corp. in San Diego, California, approached researchers at the Center for Reproduction of Endangered Species (CRES) at San Diego Zoo and Wild Animal Park with the idea of exploring microbial habitats within their rare and endangered animals. By a stroke of luck, it was then that Diversa contacted CRES geneticist Oliver Ryder, and it was agreed that Diversresearchers would work with the CRES to collect samples of microbial communities from endangered species at San Diego Zoo and compare them with similar samples taken from healthy individuals living in the wild. If endangered animals also have unique parasites and it seems a pretty safe bet that they do. The parasites' fate must be as uncertain as the fate of their hosts. In the mid-1980s, with the California condor population down to 25 individuals, conservationists took the drastic step of bringing in all the remaining birds for captive breeding at San Diego Zoo and Wild Animal Park.

"You see these on cattle, but as producers are interacting with their cattle, they need to make sure they are protecting themselves because the lone star tick also causes red meat allergy", he said.
