Aceast\u0103 cercetare ofer\u0103 prima vizualizare detaliat\u0103 a comportamentului de zbor al \u021b\u00e2n\u021barilor \u0219i furnizeaz\u0103 date m\u0103surabile care ar putea \u00eembun\u0103t\u0103\u021bi metodele de capturare \u0219i control, arat\u0103 ScienceDaily<\/a>.<\/p>\n

Pe l\u00e2ng\u0103 faptul c\u0103 sunt iritan\u021bi, \u021b\u00e2n\u021barii r\u0103sp\u00e2ndesc boli periculoase precum malaria, febra galben\u0103 \u0219i Zika, care \u00eempreun\u0103 cauzeaz\u0103 peste 700.000 de decese \u00een fiecare an.<\/p>\n

Urm\u0103rirea zborului \u021b\u00e2n\u021barilor cu imagistic\u0103 3D<\/h2>\n

Pentru a \u00een\u021belege modul \u00een care \u021b\u00e2n\u021barii se orienteaz\u0103, oamenii de \u0219tiin\u021b\u0103 au folosit camere 3D cu infraro\u0219u pentru a observa cum insectele se mi\u0219cau \u00een jurul obiectelor folosind semnale vizuale \u0219i dioxid de carbon.<\/p>\n

Apoi au introdus o persoan\u0103 \u00eentr-o camer\u0103 controlat\u0103, i-au schimbat culorile hainelor \u0219i au \u00eenregistrat modul \u00een care \u021b\u00e2n\u021barii zburau \u00een jurul ei.<\/p>\n

Concluziile, publicate \u00een Science Advances, s-au concentrat pe \u021b\u00e2n\u021barii femele Aedes aegypti (numi\u021bi \u0219i \u021b\u00e2n\u021barii febrei galbene), o specie comun\u0103.<\/p>\n

Datele sugereaz\u0103 c\u0103 \u021b\u00e2n\u021barii nu se adun\u0103 pentru c\u0103 se urm\u0103resc unii pe al\u021bii. \u00cen schimb, fiecare insect\u0103 r\u0103spunde independent la indicii din mediu, dar ajung s\u0103 se adune \u00een acela\u0219i loc \u00een acela\u0219i timp.<\/p>\n

Combina\u021bia puternic\u0103 dintre semnalele vizuale \u0219i CO2<\/h2>\n

Cercet\u0103torii au efectuat trei experimente \u00een care au ajustat \u021bintele vizuale \u0219i nivelurile de dioxid de carbon. \u00cen primul test, o sfer\u0103 neagr\u0103 a atras \u021b\u00e2n\u021barii, dar numai atunci c\u00e2nd ace\u0219tia zburau deja spre ea. Dup\u0103 ce ajungeau la obiect, de obicei nu r\u0103m\u00e2neau \u0219i plecau repede mai departe.<\/p>\n

C\u00e2nd echipa a \u00eenlocuit obiectul negru cu unul alb \u0219i a ad\u0103ugat dioxid de carbon, \u021b\u00e2n\u021barii au reu\u0219it s\u0103 localizeze sursa, dar numai de la distan\u021b\u0103 mic\u0103.<\/p>\n

C\u00e2nd at\u00e2t obiectul negru, c\u00e2t \u0219i CO2 erau prezente \u00eempreun\u0103, efectul era cel mai puternic. \u021a\u00e2n\u021barii au invadat zona, au z\u0103bovit \u0219i au \u00eencercat s\u0103 se hr\u0103neasc\u0103.<\/p>\n

Testele pe oameni dezv\u0103luie unde \u021bintesc \u021b\u00e2n\u021barii<\/h2>\n

Dup\u0103 ce a identificat importan\u021ba indiciilor vizuale statice, unul dintre cercet\u0103tori a testat comportamentul pe el \u00eensu\u0219i. A intrat \u00eentr-o camer\u0103 purt\u00e2nd diferite \u021binute, inclusiv haine complet negre, complet albe \u0219i mixte.<\/p>\n

St\u00e2nd cu bra\u021bele \u00eentinse, a l\u0103sat zeci de \u021b\u00e2n\u021bari s\u0103 zboare \u00een jurul lui, \u00een timp ce camerele de filmat le \u00eenregistrau traiectoriile. Datele au fost analizate ulterior la MIT pentru a determina regulile cele mai probabile care le ghideaz\u0103 mi\u0219carea.<\/p>\n

\u021a\u00e2n\u021barii s-au comportat de parc\u0103 cercet\u0103torul ar fi fost pur \u0219i simplu un alt obiect. Cele mai mari grupuri s-au format \u00een jurul capului \u0219i umerilor s\u0103i, care sunt zonele pe care specia le vizeaz\u0103 cel mai frecvent.<\/p>\n

Cercet\u0103torii consider\u0103 c\u0103 descoperirile lor ar putea duce la strategii mai eficiente de combatere a d\u0103un\u0103torilor.<\/p>\n","protected":false},"excerpt":{"rendered":"
