Vets and humane societies warn pet owners in Texas and New Mexico about the spread of New World screwworm, a parasite whose larvae infest open wounds in mammals, including pets and cattle. The parasite reemerged in the U.S. in June after decades of eradication efforts, with over 30 confirmed cases reported. Preventive measures include flea and tick medications, and prompt veterinary care is critical to avoid fatal infections.

Two New World screwworm cases in dogs are among over 30 confirmed in Texas and New Mexico, with larvae infesting mammals via open wounds and causing severe health risks. Veterinarians and humane societies urge vigilance, including regular wound checks and flea/tick medications to prevent infestations.

A second case of the flesh-eating screwworm fly has been confirmed in Texas, prompting a disaster declaration by the governor and coordinated efforts with federal agencies to prevent its spread. The larvae of the parasite feed on the living flesh of warm-blooded animals and humans, leading to the release of sterile flies as part of containment measures.

A hybrid honeybee in Southern California shows resilience against Varroa mites, a major cause of colony losses, by carrying fewer mites and requiring less chemical treatment. The bees' larvae are also less attractive to the parasites, suggesting early-life resistance.
