I-Fly larva yohlobo lwe Chaoborus sp
Nangona kude kube ngoku bekucingelwa ukuba iinkomo zezona ziphela izilwanyana, ngaphandle kwabantu, ezinefuthe elibalulekileyo ekufudumaleni kwehlabathi, ngoku oososayensi bafumanise ezinye ezibothusileyo: I-Chaoborus fly imibungu.
Aba bantu bahlala emanzini amade nasemachibini, besitya imibungu yengcongconi de babe badala kwaye baphume emanzini ukuze bavelise kwaye kungekudala emva kokuba beswelekile, kuba bengatyi, okanye benza njalo ngencindi.
Uphononongo olupapashwe kwi »Iingxelo zesayensi», Eqhutywa liqela leenzululwazi ezivela kwiDyunivesithi yaseGeneva (Switzerland) ngokusebenzisana neLeibniz Institute for Freshwater Ecology kunye neInland Fisheries eBerlin (IGB), ifumanise ukuba I-Chaoborus fly imibungu isebenzisa i-methane yegesi kwaye iyikhuphele emanzini.
Le mibungu, ethi ngexesha lasemini ihlale ifihlwe kwintlabathi yeli chibi, ebusuku igcwalise iingubo zayo ezincinci ngeoksijini ize inyukele phezulu ifuna ukutya. Nangona kunjalo, iingcali ziye zafumanisa kubunzulu obuthile, uxinzelelo lwamanzi lukhulu kangangokuba kuthintela ezi ngxowa ekugcwaliseni, ezenza imibungu ibhenela ekufunxweni kwemethane efumaneka kwizidumbu ukuyigcwalisa kwaye uyisebenzise kunye ne "float".
Umfanekiso - UNIGE
Ngombulelo kwesi sicwangciso sokusinda, izibungu zingonga ukuya kuthi ga kwi-80% yamandla, ngenxa yoko bafuna ukutya okuncinci. Kodwa oku kubangela ingxaki: IMethane yirhasi eyenzeka ngokwendalo kwizidibi zelwandle, kodwa xa isetyenziswa yimibungu ukuziqhubela phambili, inyibilika emanzini.. Ngokwenza njalo, inokufikelela kwiatmosferi, inegalelo kubushushu behlabathi.
Kungenxa yoko, iingcali zithi iipesenti ezingama-20 zokukhutshwa kwegesi kumanzi amatsha. Ukuxinana kwemibungu yohlobo lweChaoborus kumachibi kusuka ku-2000 ukuya kwi-130.000 yabantu kwisikwere semitha. Ukuthintela ukwanda kwayo, kwaye ngesiquphe kunciphise inani lemethane ekhutshelwe emoyeni, ababhali bacebisa ulawulo olukhulu lwamachibi amanzi, kunye naleyo mithombo inoxanduva lokukhutshwa kwemethane.
