Cercetarea s-a concentrat pe furnicile argentiniene, o specie invaziv\u0103 r\u0103sp\u00e2ndit\u0103, iar rezultatele indic\u0103 o posibil\u0103 nou\u0103 modalitate de a \u00eembun\u0103t\u0103\u021bi combaterea d\u0103un\u0103torilor, f\u0103c\u00e2nd momeala mai atr\u0103g\u0103toare \u0219i mai eficient\u0103.<\/p>\n

Furnicile argentiniene se num\u0103r\u0103 printre cele mai d\u0103un\u0103toare \u0219i costisitoare specii invazive din \u00eentreaga lume. Eforturile de combatere a acestora se bazeaz\u0103 de obicei pe momeal\u0103 otr\u0103vit\u0103, dar aceste strategii sunt adesea insuficiente.<\/p>\n

Coloniile pot ignora momeala sau o pot abandona \u00eenainte ca aceasta s\u0103 se r\u0103sp\u00e2ndeasc\u0103 pe scar\u0103 larg\u0103.<\/p>\n

Echipa de cercetare a explorat dac\u0103 cofeina, despre care se \u0219tie deja c\u0103 \u00eembun\u0103t\u0103\u021be\u0219te capacitatea de \u00eenv\u0103\u021bare la albine, ar putea ajuta furnicile s\u0103-\u0219i aminteasc\u0103 mai bine loca\u021biile momealelor \u0219i s\u0103 atrag\u0103 mai multe furnici din colonie c\u0103tre acestea.<\/p>\n

Testarea efectelor cofeinei \u00een laborator<\/h2>\n

Pentru a investiga aceast\u0103 idee, oamenii de \u0219tiin\u021b\u0103 au conceput un experiment controlat folosind diferite niveluri de cofein\u0103.<\/p>\n

Furnicile traversau un mic pod mobil din Lego c\u0103tre o suprafa\u021b\u0103 de testare, care consta dintr-o foaie A4 a\u0219ezat\u0103 peste acril.<\/p>\n

Acolo, ele \u00eent\u00e2lneau o pic\u0103tur\u0103 de solu\u021bie de zah\u0103r con\u021bin\u00e2nd 0, 25 ppm, 250 ppm sau 2.000 ppm de cofein\u0103.<\/p>\n

Echipa a urm\u0103rit mi\u0219carea fiec\u0103rei furnici cu ajutorul unui sistem automat, m\u0103sur\u00e2nd at\u00e2t timpul de deplasare, c\u00e2t \u0219i c\u00e2t de directe erau traseele lor.<\/p>\n

\u00cen total, au participat 142 de furnici, iar fiecare a efectuat patru \u00eencerc\u0103ri.<\/p>\n

\u00centre \u00eencerc\u0103ri, furnicile \u00ee\u0219i puteau desc\u0103rca hrana colectat\u0103, iar suprafa\u021ba de testare era \u00eenlocuit\u0103 pentru a le \u00eempiedica s\u0103-\u0219i urmeze propriile urme de feromoni.<\/p>\n

Trasee mai drepte, \u00eenv\u0103\u021bare mai rapid\u0103<\/h2>\n

Furnicile care au primit doar zah\u0103r au ar\u0103tat o \u00eembun\u0103t\u0103\u021bire nesemnificativ\u0103 \u00een timp, indic\u00e2nd faptul c\u0103 nu \u00eenv\u0103\u021bau eficient loca\u021bia recompensei.<\/p>\n

\u00cen schimb, furnicile c\u0103rora li s-au administrat cantit\u0103\u021bi mici sau moderate de cofein\u0103 au devenit rapid mai eficiente.<\/p>\n

Pentru furnicile expuse la 25 ppm de cofein\u0103, timpul de c\u0103utare a hranei a sc\u0103zut cu 28% la fiecare vizit\u0103. La 250 ppm, \u00eembun\u0103t\u0103\u021birea a ajuns la 38%.<\/p>\n

De exemplu, o furnic\u0103 c\u0103reia ini\u021bial \u00eei lua 300 de secunde s\u0103 ajung\u0103 la recompens\u0103 putea reduce acest timp la 113 secunde la doza mai mic\u0103 \u0219i la doar 54 de secunde la doza intermediar\u0103 p\u00e2n\u0103 la ultimul test.<\/p>\n

Nivelul cel mai ridicat de cofein\u0103 nu a produs acela\u0219i beneficiu.<\/p>\n

Descoperirile sugereaz\u0103 c\u0103 cofeina ar putea juca un rol \u00een \u00eembun\u0103t\u0103\u021birea strategiilor de combatere a d\u0103un\u0103torilor pentru furnicile argentiniene. Cofeina ar putea cre\u0219te eficien\u021ba cu care otrava se r\u0103sp\u00e2nde\u0219te \u00eentr-o colonie \u00eenainte ca furnicile s\u0103 o detecteze.<\/p>\n","protected":false},"excerpt":{"rendered":"
