Medzin\u00e1rodn\u00fd t\u00edm vedcov preto vyu\u017eil princ\u00edp podmie\u0148ovania zn\u00e1my z experimentu s Pavlovov\u00fdm psom, ktor\u00fd si spojil pr\u00edchod potravy so zvukov\u00fdm sign\u00e1lom. Kom\u00e1re egyptsk\u00e9 (Aedes aegypti), ktor\u00e9 pren\u00e1\u0161aj\u00fa choroby ako hor\u00fa\u010dka dengue, v\u00edrus zika, \u017elt\u00fa zimnicu \u010di v\u00edrus chikungunya, umiestnili vedci do sie\u0165ov\u00e9ho boxu a pon\u00fakli im vak s teplou ov\u010dou krvou.<\/p>\n
Prekvapiv\u00fd experiment<\/p>\n
Ke\u010f vedci pridali pach repelentu DEET, kom\u00e1re sa od zdroja vz\u010fa\u013eovali. N\u00e1sledne v\u0161ak vedci hmyz po\u010das 20 sek\u00fand k\u0155mili teplou krvou, pri\u010dom po\u010das posledn\u00fdch desiatich sek\u00fand uvo\u013e\u0148ovali aj pach repelentu. Tento postup zopakovali trikr\u00e1t. Ke\u010f potom kom\u00e1re vystavili len v\u00f4ni repelentu, viac ne\u017e 60 percent z nich sa pok\u00fa\u0161alo po\u0161t\u00edpa\u0165 tkaninu, aj ke\u010f v nej nebola krv. V \u010fal\u0161ej \u010dasti experimentu jeden z vedcov nastavil kom\u00e1rom obe ruky – jednu \u201e\u010dist\u00fa\u201c a druh\u00fa nastriekan\u00fa repelentom DEET. Kom\u00e1re pod\u013ea v\u00fdsledkov jednozna\u010dne uprednostnili ruku pokryt\u00fa repelentom.<\/p>\n
Vedci dospeli k podobn\u00fdm v\u00fdsledkom aj pri pokusoch s cukrom namiesto krvi. Kom\u00e1re sa toti\u017e vo vo\u013enej pr\u00edrode \u017eivia preva\u017ene rastlinn\u00fdm nekt\u00e1rom. Spoluautor \u0161t\u00fadie Cl\u00e9ment Vinauger z univerzity v americkom \u0161t\u00e1te Virg\u00ednia uviedol, \u017ee doteraz sa v\u0161eobecne predpokladalo, \u017ee repelenty funguj\u00fa v\u00fdlu\u010dne na z\u00e1klade svojho chemick\u00e9ho zlo\u017eenia. Nov\u00e1 \u0161t\u00fadia v\u0161ak pod\u013ea vedcov nazna\u010duje, \u017ee kom\u00e1re nereaguj\u00fa len na samotn\u00fa chemick\u00fa l\u00e1tku, ale aj na to, ako ju ich mozog vyhodnot\u00ed na z\u00e1klade predch\u00e1dzaj\u00facich sk\u00fasenost\u00ed.<\/p>\n
\u201eUkazujeme, \u017ee mozog kom\u00e1ra dok\u00e1\u017ee t\u00fato reakciu prep\u00edsa\u0165 na z\u00e1klade sk\u00fasenosti,\u201c vysvetlil Vinauger. \u201eTo, \u010do sa hmyz nau\u010dil, je rovnako d\u00f4le\u017eit\u00e9 ako samotn\u00e9 p\u00f4sobenie chemickej l\u00e1tky. Mysl\u00edm si, \u017ee ide o z\u00e1sadn\u00fa zmenu poh\u013eadu,\u201c dodal. Lazzari v\u0161ak z\u00e1rove\u0148 upozornil, \u017ee v pr\u00edrode by boli potrebn\u00e9 \u201eve\u013emi \u0161pecifick\u00e9 podmienky\u201c, aby sa kom\u00e1re spr\u00e1vali rovnako ako v laborat\u00f3riu. \u0160t\u00fadia bola publikovan\u00e1 vo vedeckom \u010dasopise Journal of Experimental Biology.<\/p>\n","protected":false},"excerpt":{"rendered":"PAR\u00cd\u017d – Kom\u00e1re sa dok\u00e1\u017eu nau\u010di\u0165 sp\u00e1ja\u0165 si pach najpou\u017e\u00edvanej\u0161ieho repelentu na svete s potravou a po \u201ev\u00fdcviku\u201c…\n","protected":false},"author":2,"featured_media":83564,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[8],"tags":[14184,25882,33,6602,43,40,42,36,50,10885,49,48],"class_list":["post-83563","post","type-post","status-publish","format-standard","has-post-thumbnail","category-svet","tag-hmyz","tag-komar","tag-news","tag-repelent","tag-sk","tag-slovak","tag-slovencina","tag-spravy","tag-svet","tag-veda","tag-world","tag-world-news"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@sk\/116659044412037894","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts\/83563","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/comments?post=83563"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/posts\/83563\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/media\/83564"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/media?parent=83563"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/categories?post=83563"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/sk\/wp-json\/wp\/v2\/tags?post=83563"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
