Ososayensi abavela eSmithsonia Institution of Trological Research bathole izidakamizwa ezinqwabelana ezithola ukulawula izicabucabu ngokuziguqula zibe yi-Zombies. Mayelana nayo kubhala i-New Atlas.
Abaphenyi babona iminyovu yasePolysphincta - kuyaziwa ukuthi izinambuzane zibeka izibungu emhlane wesicabucabu futhi ziphoqelele abokugcina ukuba banakekele amawundlu abo.
Ngemuva kokubopha izibungu, izicabucabu ze-zombie ziqala ukufaka i-web evikelayo, eyakha ikhukhunathi elizungeze isibungu bese ivumela ukuba ikhule ngokushesha. Ngemuva kokuthi izibungu ziphenduke imfumba, zidla isicabucabu bese ziqala ukufuna isisulu esisha.
Indaba yocwaningo kwakuyindlela ama-waster enza izicabucabu zenze ngayo izinto ezizidingayo. Ukuqashelwa kubonise ukuthi lapho lilunywa, izinambuzane zijova i-ecdysone kwizicabucabu, into ekhiqizwa wayo enikeza isicabucabu uphawu lokuthi ukuqala kokuncibilika.
Ngenxa yalokhu, i-arthropod iqala ukufaka i-web evikelayo, evame ukukhiqiza lapho isencibilika, kodwa ingazungezi yona uqobo, kepha izungeze isibungu se-wasp.
Phambilini, izazi zezinto eziphilayo zaseMelika zathola ukuthi ukhunta oluyisinambuzane i-Entomophthora muscae, elihunyushwe lisuselwa esiLatinini ngokuthi "ukubulala izinambuzane", lingena ebuchosheni bezimpukane zikaDrosophila futhi lizithobe ngokuphelele entandweni yalo.
Ukukhohlisa kwehomoni kwizicabucabu
Ngakho-ke, izibungu zikwazi kanjani ukuthola izicabucabu ukuze zibenzele amakhukhunathi? Ucwaningo olusha luveze le mfihlo - kuvela ukuthi izibungu zijova i-hormone ebizwa nge-ecdysone emizimbeni yesicabucabu. Kukhohlisa umzimba wezisulu futhi iqale inqubo yokuncibilikisa, lapho izicabucabu ziba sengozini futhi zizame ukuzivikela ngosizo lwegobolondo kusuka kuhlobo olukhethekile lwewebhu. Kodwa-ke, ekugcineni, lokhu kuvikela kuba "yindlu" yokuhlanzeka okuzayo, kanti izicabucabu uqobo zingukudla kwazo.
Endabeni yama-Zombies, sincoma nokufunda izinto zethu ukuthi abacwaningi baseDuke University bakwazile kanjani ukuvusa ubuchopho bengulube amahora amane ngemuva kokushona kwakhe.
