Kungani izimpukane zihlikihla izidladla zazo: imfihlakalo ye-Diptera zungu
Cishe wonke umuntu waqaphela ukuthi lapho impukane ihlezi endaweni ethile, iqala ukugudla izidladla zayo komunye nomunye, njengokungathi iyawahlanza. Ingabe inhlanzeko yomuntu siqu ibaluleke kangaka kulezi zinambuzane ezigaqa phakathi kweziqukathi zikadoti nokudla okubolayo?
Okuqukethwe
Ukuthi izidladla zempukane zihlelwa kanjani futhi buyini ukuhluka kwazo
Impukane iwuhlanza ngempela umzimba ngale ndlela, ikakhulukazi izitho. Kodwa lokhu akakwenzi ngenxa yokuhlanzeka ngokweqile, kodwa ngenxa yesimo sakhe somzimba.
Izimpukane zisebenzisani izitho zazo?
- Ngenxa yezidladla ezinjalo ezinhle, i-arthropod igcina isibuko, ingilazi nanoma iyiphi enye indawo ebushelelezi.
- Ingakwazi ukuhamba kalula ophahleni kanye nezindonga ibheke phansi futhi ingene emagumbini angafinyeleleki kakhulu ekamelo.
- Ngaphezu kwalokho, isinambuzane sisebenzisa ama-bristles atholakala kuma-pulvilles njengesitho sokuthinta nokuhogela, esinquma ukunambitheka nokuhleleka komkhiqizo.
- Lapho izidladla zazisa impukane ukuthi isifike entweni edliwayo, umuntu uyayinambitha ngohlobo lolimi olusesimweni se-libella pad. Okusho ukuthi, okokuqala izinambuzane zizama ukudla ngezinyawo zaso, bese kuphela nge-proboscis yayo nama-sucking blades.
Kungani impukane igudla izidladla zayo: izizathu eziyinhloko
Phakathi nokunambitha nokunyakaza okunjalo, izidladla zempukane ziqoqa ngokushesha uthuli nokungcola okwephula ukunamathela phezulu.
Ukuze siqhubeke sikhasa ngaphandle kwezithiyo, isinambuzane siphoqeleka ukuthi sihlale sihlanza amathiphu emilenze yaso ezinhlayiyeni zangaphandle eziqoqiwe, okukhuthaza ukukhululwa kwemfihlo enamathelayo kuma-carbohydrates nama-lipids.
Ngakho bagcina izitho ezibalulekile zisesimweni sokusebenza. Yonke inqubo yenhlanzeko iqukethe izingxenye eziningana. Okokuqala, izimpukane zihlanza imilenze yangaphambili, bese zigeza amakhanda azo nemilenze yangemuva ngalezi zidladla, futhi ekugcineni zisula amaphiko azo.
Kwenzekani uma ugcoba imilenze yezimpukane
Uma ubhekisisa indawo engaphezulu lapho isinambuzane sihamba khona, umuntu angabona iminonjana enombala onsundu ngendlela yochungechunge lwamachashaza agqamisa indawo yama-outgrowths-pulville. Izazi zezinambuzane ziye zathola ukuthi akhiwe ngama-triglycerides.
Uma ususa amafutha emilenzeni yempukane, uwacwilisa kancane ku-hexane, ukunyakaza kwe-arthropod ngeke kwenzeke.
Yiziphi izifo eziyingozi izimpukane ezithwala ngezidladla zazo?
Naphezu kokuhlanzwa njalo kwezitho, izimpukane yizona ezithwala izifo ezithathelwanayo kanye nezifo ezithathelwanayo. Njengomphumela wocwaningo, amagciwane afinyelela ezigidini eziyisi-6 atholakala ebusweni bomuntu oyedwa kuphela, futhi afinyelela ezigidini ezingama-28 emathunjini awo.
Kuyafaneleka ukuphawula lokho ezindaweni zokuhlala ezinezimo ezingahlanzekile, ama-microorganisms angaba yizigidi ezingu-500 angaba ezimpukaneni. Amagciwane e-Pathogenic afika ezidladleni zesinambuzane esuka kudoti wezinto eziphilayo futhi esuka kuwo aye ekudleni. Ngokudla ukudla okunjalo, umuntu ungenwa yigciwane noma adliswe ushevu. Phakathi kwezifo eziyingozi ezithwalwa izimpukane yilezi:
- isifo sofuba;
- uvendle;
- i-salmonellosis;
- i-brucellosis;
- udiptheria;
- i-tularemia;
- udayi;
- typhoid;
- ikholera;
- isifo sevangeli;
- i-paratyphoid;
- ukuhlangana.
Izinambuzane eziningi ezidladleni zazo zisakaza amaqanda ezikelemu, ukutheleleka kwakho okwenzeka ngokudla. Kuye kwafakazelwa ukuthi kwakuyizimpukane ukuthi ngezikhathi ezithile zaba yimithombo yezifo eziwumshayabhuqe ezingathi sína.
Ngokwesibonelo, ekhulwini le-112 eRussia babangela izifo eziningi ze-jaundice ezingu-XNUMX, futhi eCuba nasePuerto Rico phakathi neMpi YabaseSpain NaseMelika babangela ukugqashuka kwesihudo ne-typhus.
Ngisho namanje, i-trachoma ephuphuthekisa, ebangelwa izinhlobo ezithile zezimpukane, ihlasela abantu abangaba yizigidi ezingu-8 minyaka yonke.
