Prskanje protiv insekata: praksa 'zamagljivanja'

Hoću li se zateći vozeći se kroz toksičnu maglu kemikalija ako uhvatim trajekt u 20:30 iz Splita? To je bilo moje pitanje u srijedu 27. rujna 2017. godine. Akcija 'zamagljivanja' za suzbijanje insekata se trebala provoditi na području Općine Jelsa s početkom u 22 sata i trajati do 4 sata ujutro.

Dolazeći u Stari Grad u 22:30 te večeri, mogla sam se naći direktno iza vozila za "zamagljivanje" ako bi smo se slučajno našli na istom putu za Pitve. Znajući kakvo sredstvo je bio korišten 2017. godine, pomisao na to, da bi se u njemu trebala zateći nije bila ni malo privlačna. Jedne večeri 2012. godine, vraćala sam se prema svom autu na parkiralištu u Hvaru, kada sam iznenada začula snažan zvuk šištanja i opazila ogroman kombi, kojem je iz oba prozora izlazio magloviti oblak. Iza kombija je bio automobil i motocikl, kao i skupina pješaka. Budući da je vozilo za 'zamagljivanje' napuštalo grad, u koloni iza njega vozilo se još nekoliko automobila. S obzirom da na ovom djelu ceste nije moguće pretjecati, svi su se vukli za njim uzbrdo u tužnoj koloni 'kupajući' se u vrtlogu toksina. Budući da se točna ruta i vrijeme kretanja vozila za "zamagljivanje" ne objavljuju, nije moguće isplanirati gdje ćemo se nalaziti kako bi izbjegli prskanje ako se zateknemo vani tijekom te noći.

Program za suzbijanje insekata je definitivno uzaludan

Ujutro nakon ovog rujanskog 'zamagljivanja' imamo u Pitvama lijep sunčan dan. Vrabac sjedi na mojoj ogradi i izgleda nekako bez volje. Jesu li mu možda poubijali doručak? Kad bolje pogledam, vidim svugdje naokolo rojeve insakata. Mnogo mušica i komaraca najnormalnije nastavljaju svoje aktivnosti u punoj snazi. Očigledno je pokušaj suzbijanja propao. Ali kolika je kolateralna šteta? Osobna iskustava iz programa suzbijanja insekata pokazuju, da su komarci koji prežive otporni, ljuti i sve virulentniji. Otrov neizbježno stvara promjene u njihovim sustavima. I da ne zaboravimo neželjene posljedice na insekte, koji nisu ciljana skupina, posebice pčele.

Ugriz komaraca je OK?

U Hrvatskoj je godišnje od komaraca ugrizeno nekoliko tisuće ljudi. Prema službenim statistikama, bolesti uzrokovane ugrizom komaraca nisu nikakav problem. Na primjer onih nekoliko izoliranih slučajeva malarije i denga groznice su uglavnom uvezene, obično od pomoraca, koji se vraćaju iz tropskih zemalja. U zemljama u kojima su bolesti uzrokovane ugrizom komaraca endemske, iskustvo je pokazalo, da je pokušaj suzbijanja insekata insekticidima nedjelotvoran i kontraproduktivan jer brzo postaju otporni na svaki otrov, koji se koristi.

Ugrizi komaraca su iritantni, ali velika većina ne uzrokuje bolest. Iritacija nije razlog za uklanjanje cijele vrste, čak i ako bi to bilo moguće. Svakako i nije moguće i upotreba pesticida jednostavno samo povećava broj štetnika, nikako ih ne smanjuje. Prije sam bila vrlo osjetljiva na ugriz komaraca, sada više nisam. Promjena se dogodila kada sam počela uzimati vitamin B kao dodatak prehrani. I dalje me grizu komarci, ali ugriz ne uzrokuje značajnije iritacije i mjesto ugriza zacijeli vrlo brzo. Možda to neće biti rješenje sa svih, ali zasigurno je pomoglo mnogim ljudima, koje poznajem.

'Zamagljivanje' na Hvaru

Rute 'zamagljivanja' se ne objavljuju. Ono što možemo reći mi u udruzi Eco Hvar, jer smo to vidjeli vlastitim očima je, da vozilo odlazi iz grada Hvara po cesti uz policijsku postaju; prolazi cestom kroz Vitarnju između Jelse i Vrboske; prolazi kroz Gornje Pitve prema tunelu za Zavalu. Kako prolazi kroz gornje Pitve, ide vrlo blizu kuća, koje se nalaze uz cestu, prskajući otrov na određenoj visini. Otrovi stoga dospiju do parkiranih automobila, kontejnera za smeće, terase na kojima se igraju djeca i obitelji uživaju u zajedničkom ručku, u vrtove sa voćem, povrćem, sa pilićima i kozama, u vinske podrume, trgovine sa hranom, kuhinje, dnevne boravke i spavaće sobe. S obzirom, da upozorenje objavljeno na oglasnoj ploči Općinskog Doma u Jelsi obično nitko ni ne primijeti i ljetne večeri su vruće, mnogi ljudi ne zatvaraju svoje grilje.

Čak i ako izbjegnemo izravan kontakt sa vozilom za 'zamagljivanje', ne možemo izbjeći kontakt sa otrovima. Udišemo ih, ulaze u naša tijela kroz dodir sa našom kožom. Jednostavno, otrovi ne nestanu tek tako nakon što obave svoj posao na ciljanim insektima preko noći. Ostaju na površinama prskanih područja i uz pomoć vjetra mogu se proširiti i puno dalje. Utjecaj otrova se produžuje još neko vrijeme, vjerojatno nekoliko dana nakon provedbe 'zamagljivanja'. Ne donosi štetu samo komarcima, koji su glavna meta.

Ujutro nakon rujanskog prskanja 2017. godine odlazim prema svom auto, koje je parkirano uz cesto i dobilo je znatnu dozu otrova. Hodajući niz cestu, sigurno sam pokupila otrov i nosim ga na svojim cipelama. Na vratima svog automobila pronalazim bogomoljku, koja izgleda kao da se bori sa svojim vlastitim sjenama: jesu li je izludili otrovi? Otvaram vrata automobila, moja ruka je vjerojatno kontaminirana. Unutrašnjost automobila vjerojatno isto: koliko otrovnih ostataka dišem ili dodirujem dok vozim? Svjesna ovoga svega, osjećam se uznemireno, što je svakako puno gore od nelagode, koju donosi običan ugriz komaraca.

Došlo je vrijeme za promjenu

Suzbijanje insekata kroz kemikalije ne postiže svoj cilj ni u Hrvatskoj ni u drugim zemljama. Prema zakonu, trebalo bi postojati odgovarajuće upozorenje o 'zamagljivanju'. Ono se obavlja tijekom ljetne sezone, kada se stanovništvu otoka Hvara pridružuju mnogobrojni gosti iz različitih dijelova svijeta. Mještani su loše informirani, za strance niti ne postoji nikakvo upozorenje. Živjelo blaženo neznanje, ali držati ljude u mraku o očito opasnoj praksi je neprihvatljivo i neoprostivo. Dva dana nakon 'zamagljivanja' na našem području, šokirana prijateljica iz Vrisnika reagirala je na vijest o prskanju na ovaj način: "Jučer su me pojeli komarci!" Na upit (e-mailom) zna li, da je njeno područje bilo prije dvije noći prskano, građanka grada Starog Grada je s užasom reagirala: "J...e, nisam imala pojma!!!"

Zakon i praksu je potrebno hitno razmotriti i revidirati.

Kemijski pesticidi su svugdje oko nas - i u našim tijelima. Ulaze u našu prehranu kao opasan koktel. Mi smo svi izloženi njihovim nuspojavama. Ja sam osobno dala uzorak svoje kose na analizu u veljači 2021., testiranje u laboratoriju Kundzu Science u Francuskoj pokazalo je da u sebi imam tri opasne tvari - fungicid azoksistrobin, herbicid glifosat i insekticid permetrin. Budući da ja uopće ne koristim pesticide, ta kontaminacija je očito došla iz prehrane i/ili okoliša.

  • ‘These are human fires, not wildfires’: Dunwich reflects on the devastation

    As residents, nature wardens and experts consider the damage to the heathland and how to restore it, the climate crisis is foremost in their minds

    A local community pulling together, emergency services saving homes and caravan parks from catastrophe, and farmers and nature reserve wardens working to rapidly create fire breaks to halt a marauding fireball 40 metres high – there was plenty to praise the week after a swathe of east Suffolk burned.

    But local people were also in tears at the blackened, ruined state of more than 112 hectares (277 acres) of Dunwich Heath, mourning the devastation of a much-loved nature reserve alongside neighbouring Minsmere. The rare birds that inhabit the reserve have lost crucial habitat, while the rare invertebrate species there will have been “decimated”, according to the reserve staff.

  • Plastics contamination an ‘overlooked’ concern in food waste schemes, experts say

    Researchers find microplastics can persist in compost, leaching into agricultural soils

    Plastic contamination should be a central concern in efforts to deal with food waste, which campaigners call one of the most overlooked problems of the climate crisis, researchers have said.

    This is despite the fact that, as the chef, author and activist Max La Manna puts it, food waste management is “one of the few climate problems where everyone wins”.

  • Country diary: We’ve had fires here in the Cairngorms before. This one has changed things | Amanda Thomson

    Abernethy: It’s been a period of heartbreak and gratitude, mourning the scorched landscape and staying away from home when the smoke got too close

    Parts of the Cairngorms have been on fire for over three weeks. Many places I take for granted that I can walk to are off-limits. Huge swathes of moorland that should be purple with heather, understoreys that should be thick with blaeberries, granny pines and younger trees, are scorched black. In places, the fires has burned down into the tree root system and the peat layer, and may smoulder for weeks.

    It’s been a period of uncertainty and despair. I’ll never forget the day the wind changed direction and a huge plume of smoke rose behind the trees immediately beyond our house. We waited to see if we would be evacuated, gathered passports, important documents, medicines, and packed a bag of clothes. When residents of nearby Nethy Bridge were advised to evacuate, we stayed with a friend just outside the perimeter for the night, something I never imagined having to do.

  • ‘I couldn’t breathe’: the deadly health burden of wildfire smoke

    Scientists race to untangle complex links between exposure and mortality as fire weather grows more prevalent

    A thousand kilometres from the infernos gorging on northern Ontario’s boreal forests, Erin O’Connor watched the sky above Canada’s biggest city turn an “almost post-apocalyptic” orange as it filled with light-scattering particles of soot and ash. Stepping outside the halls of Toronto General hospital, where air filters were keeping patients safe from the worst of the fumes, she was struck by a smell so strong it felt like standing by a campfire.

    “It really hit you in the face as soon as you walked outside,” said O’Connor, who runs University Health Network’s emergency department and saw a rise in patients presenting with allergies and shortness of breath. “As the days progressed, it was like that everywhere. It seemed even inside you could smell that burning.”

  • ‘Fearless and quietly astonishing’: the dragonfly that migrates further than any other insect

    Wandering gliders are descended from some of the earliest known insects – and breed as one global population

    Revealed: the top 10 invertebrates of the year

    All hail the wandering glider, a citizen of the globe, an insect for all of us.

    Whenever we see a dragonfly zipping through the airspace and devouring tiny insects with aplomb, we can appreciate they are so timelessly effective that they have barely needed to tweak their way of life in 200m years. Odonates are directly descended from some of the earliest winged insects, known as griffin flies, which evolved around 317m years ago.

    It’s invertebrate of the year again! From August 3-12, every day we’ll be profiling one of the thousands of amazing invertebrates that our readers have nominated, and then, when you’ve got to hear about all of them, we’ll open the voting so you can choose your favourites. Don’t hesitate to get in touch with thoughts and ideas: email us at [email protected] with Invertebrate in the subject line.

    The mission of the Flock app is quietly subversive: to encourage users to ditch their screens and explore the wonderful world of birding

    On a brilliantly bright afternoon in his gallery and studio in Bolinas, a small town on the northern California coast, Keith Hansen was putting the finishing touches on a watercolor of an almost improbably flamboyant painted bunting.

    With an ultra-fine sable brush, he made a few intricate additions to the cobalt blue plumage on the bunting’s head, and, satisfied with his work, slipped the watercolor into a stout binder that every few days welcomes a new addition.
