MORGANTOWN, W.V. – Murder hornets have had their time in the spotlight. Now, scientists say they've discovered “zombie cicadas.”It's a playful name from researchers at West Virginia University, who say they've found that a parasitic fungus, called Massospora, can play mind games on cicadas, causing them to infect others.Researcher showed that the psychedelic fungus can manipulate male cicadas into flicking their wings like females – a mating call – which tempts unsuspecting male cicadas and infects them.The fungus contains chemicals like those found in hallucinogenic mushrooms, according to research published in the journal PLOS Pathogens.“Essentially, the cicadas are luring others into becoming infected because their healthy counterparts are interested in mating,” said Brian Lovett, study co-author and post-doctoral researcher with the Davis College of Agriculture, Natural Resources and Design. “The bioactive compounds may manipulate the insect to stay awake and continue to transmit the pathogen for longer.”The authors of the study compared the effects of the fungus to a “B-horror movie.” Massospora spores gnaw away at a cicada’s genitals, butt and abdomen, replacing them with fungal spores. Then, Lovett says they “wear away like an eraser on a pencil.”Lovett also compared the transmission of the behavior-modifying virus to rabies. He says both rabies and entomopathogenic fungi enlist their living hosts for successful “active host transmission.”“When you're infected with rabies, you become aggressive, you become afraid of water and you don't swallow,” Lovett said. “The virus is passed through saliva and all of those symptoms essentially turn you into a rabies-spreading machine where you're more likely to bite people."In that sense, Lovett says many of us are familiar with active host transmission.“Since we are also animals like insects, we like to think we have complete control over our decisions and we take our freewill for granted,” he said. “But when these pathogens infect cicadas, it's very clear that the pathogen is pulling the behavioral levers of the cicada to cause it to do things which are not in the interest of the cicada but is very much in the interest of the pathogen.”Researchers say cicada nymphs could encounter Massospora in their 17th year as they emerge from the ground to molt into adults or on their way down to feed on roots for 17 years.“The fungus could more or less lay in wait inside its host for the next 17 years until something awakens it, perhaps a hormone cue, where it possibly lays dormant and asymptomatic in its cicada host,” said co-author Matthew Kasson.As grotesque as an infected decaying cicada sounds, researchers say they’re generally harmless to humans. They also reproduce at such a rate that the fungi’s extermination of hordes of cicadas has little effect on their overall population.“They're very docile,” Lovett said. “You can walk right up to one, pick it up to see if it has the fungus (a white to yellowish plug on its back end) and set it back down. They’re not a major pest in any way. They’re just a really interesting quirky insect that’s developed a bizarre lifestyle." 3172
MILWAUKEE, Wis. -- A Wisconsin man is accused of driving across Milwaukee with the body of a man who had fatally overdosed in the passenger seat for 13 hours straight.The Washington County Sheriff’s Office said Thursday it has arrested the 34-year-old man in connection to the death of the victim, whose lifeless body was later found in the Allenton Marsh.The sheriff’s office says the suspect, whom they did not name, was last seen with the victim, 30-year-old Stephen Lombard, in the Village of Jackson on July 27.A missing persons investigation was launched with the assistance of the Wisconsin Division of Criminal Investigations.A several-month-long investigation eventually concluded that on the night of July 27, Lombard and the suspect were in Milwaukee using illegal narcotics.Investigators believe that at some time, Lombard stopped breathing while inside the suspect’s vehicle. The suspect did not seek medical aid, authorities say, and Lombard died from a probable drug overdose.The suspect then drove around Milwaukee with Lombard's body still in the passenger seat for the next 13 hours. During that time, the suspect used the victim's debit card at several locations, authorities say.Investigators believe the suspect then discarded Lombard’s body on July 28 in the Allenton Marsh, off CTH W, north of CTH S in the Town of Addison.That's where authorities found a body they believe to be Lombard's.DNA analysis will be required for positive identification. An autopsy was completed and the results are pending, the Washington County Sheriff’s Office says.“It is unconscionable to think that someone would have such wanton disregard for human life to not seek medical attention for someone in need," said Washington County Sheriff Martin Schulteis in a statement."It shocks the conscience to think that they would then drive around with the body for thirteen hours while emptying the victim’s bank account and eventually discarding the body like a piece of trash," he said. 1995
