Indijski znanstvenici potvrdili sumnju: Mobilni telefoni krivi za nestanak pčela na Zemlji

Pčele osjete signal mobitela!

DILJEM svijeta u posljednjih nekoliko godina alarmantno se smanjio broj pčela i dosad se nije znalo što je tome uzrok. Iako u pčela nije pronađena nikakva bolest, njihov broj dramatično opada. Dosad su među moguće uzroke navodili nepoznate viruse, pesticide, genetski inženjering sjemena i klimatske promjene, ali ni za što nisu pronađeni dokazi.

Nestanak velikog broja pčela počeo se primjećivati kroz opadanje zaliha voća i povrća za čije su oprašivanje najzaslužnije upravo pčele, prenosi Telegraph.

Znanstvenici sa Sveučilišta Punjab u Indiji napravili su pokus u koji su uključili dvije košnice pčela. U jednu košnicu su stavili mobilni telefon na kojem su dvaput dnevno simulirali poziv u trajanju od 15 minuta. U drugu košnicu su stavili imitaciju mobilnoga telefona koji nije davao nikakav signal.

Nakon tri mjeseca znanstvenici su otkrili da se broj pčela u košnici s aktivnim mobilnim telefonom znatno smanjio. Pčele izložene zračenju mobilnog telefona su se neobično ponašale, izlegle su znatno manje jajašaca i nisu proizvele med.

Ovim pokusom su znanstvenici u Punjabu potvrdili više godina spominjanu mogućnost da su mobilni telefoni krivci za tako rapidno izumiranje pčela na svijetu.

Colony collapse disorder was first applied to a drastic rise in the number of disappearances of Western honey bee colonies in North America in late 2006.[2] Colony collapse is economically significant because many agricultural crops worldwide are pollinated by bees. European beekeepers observed similar phenomena in Belgium, France, the Netherlands, Greece, Italy, Portugal, and Spain,[3] and initial reports have also come in from Switzerland and Germany, albeit to a lesser degree[4] while the Northern Ireland Assembly received reports of a decline greater than 50%.[5] Possible cases of CCD have also been reported in Taiwan since April 2007.[6]

Nestanak pčela zabilježen je i u Hrvatskoj. Zimus su hrvatski pčelari pretrpjeli 50-postotni gubitak pčelinjih zajednica, upozorio je u ožujku predsjednik Hrvatskoga pčelarskog saveza Martin Kranjec.

Culprits identified in worldwide honeybee die-off

Over the past few years, there's been some panic over a dramatic decrease in the world's honeybee population, an occurrence that has left many experts scratching their heads. Now it appears as though part of the bee die-off mystery has been solved.

As reported by Kirk Johnson of the New York Times, a somewhat odd pairing of entomologists and military scientists has pinpointed likely culprits: a fungus and a virus, both of which flourish in cool, wet environments. While scientists aren't certain, they believe the fungus and virus work together to hamper the insect's digestive system. Each is relatively harmless on its own, Johnson says, but their combination is deadly.

The findings by Army scientists in Maryland and bee experts in Montana are outlined in a paper published by the Public Library of Science's PLoS One.

The honeybee die-off -- populations in the United States alone are believed to have dropped 20 percent to 40 percent -- was a source of growing concern because of the vital role bees play in the food chain. As a 2007 "60 Minutes" report on the die-off noted, the bees are "crucial to the production of one-third of the foods we eat" because of their role in pollination.

The phenomenon of entire beehives disappearing has come to be known as colony collapse disorder.

Informed speculation previously blamed a host of factors for the die-off, such as pesticides and the cell-phone-driven increase of radiation in the atmosphere.

Though the identification of a cause is encouraging, scientists still find reason for concern.

"I hope no one goes away with the idea that we've actually solved the problem," Jeff Pettis of the U.S. Department of Agriculture's Agricultural Research Service told MSNBC. "We still have a great deal of research to do to resolve why bees are dying in the U.S. and elsewhere."

Mrzim med..., te izlučevine insekata! Mrzim kad mi konobar donese med uz čaj umjesto šećera! Mrzim rukle ljepljive od meda, mrzim pčele! Bodu! Crke dabogda sve!

Med jeste zdrav, znam to i sam.
Dobro malo se šalim da mrzim med, ne mrzim, mogu ga jesti, ali mi nije nešto posebno... kao dijete sam ga ponekad jeo, a sada... mislim da ga nisam okusio u zadnjih 10 godina.
A dobro, svi mi znamo da ima meda i "meda", treba naši onaj pravi, prirodni.
A što se tiče pčela... prije rata živio sam u blizini tipa koji je imao košnice pa sam morao prolaziti pored njegove kuće kada idem u školu i nazad. I znam vrlo dobro da bodu ponekad i "nedužne prolaznike", bez obzira što pisalo u znanstvenim priručnicima.

ja se pomalo bavim pcelarstvom ,prije 2 god imao sam 50 kosnica i u roku od deset dana su mi ostale 4 samo ,poslje sam nosio na analizu u sarajevo medjutim nisu nasli nista tek nakon nekog vremena sam cuo da je u okolici livna masa pcelara imala ogromne gubitke i niko nezna zasto

p.s.

u nas u west herzegovina, nekad bi se reklo da -'čele umiru-, a ne ugibaju, toliko se cijenila i poštivala ta beštijica.
