Isicabucabu esibomvu sibomvu singokomndeni wama-Arachnid wesigaba sama-Arachnids. Igama lesiLatini lohlobo lwazo yiLatrodectus hasselti.
Ukusatshalaliswa kwesicabucabu esibomvu emuva.
Isicabucabu esisekela ngokubomvu sisatshalaliswa kulo lonke elase-Australia. Lolu hlobo luhlala naseNew Zealand (North naseNingizimu Islands), olwethulwe lapho ngengozi ngenkathi kuthuthwa amagilebhisi asuka e-Australia. Indawo yokuhlala ihlanganisa izindawo eziningi eziseNingizimu-mpumalanga ye-Asia nasenyakatho yeNdiya. Isicabucabu esinomhlane obomvu sisanda kubonwa eningizimu nasenkabeni yeJapan.
Izindawo zesicabucabu esibomvu emuva.
Izicabucabu ezinemibala ebomvu zivame ukutholakala ezindaweni ezisemadolobheni, zikhetha ukukhosela ezimeni zezulu ezingezinhle ezindaweni ezahlukene. Zitholakala ezindaweni ezisemadolobheni nezasemadolobheni ezindaweni zonke zase-Australia, zikhetha isimo sezulu esishisayo nesipholile. Azandile kakhulu ezindaweni ezingama-savanna nasehlane, ezingatholakali ezinkangala. Ukuvela kwezicabucabu ezinobuthi eJapan kukhombisa ukuthi ziyakwazi futhi ukuphila ngaphansi kwamazinga okushisa aphansi kakhulu (-3 ° C).
Izimpawu zangaphandle zesicabucabu esibomvu emuva.
Isicabucabu esibomvu emuva sihlukile kunezinhlobo ezihlobene nokuba khona komugqa obomvu ohlangothini olungaphezulu lwe-cephalothorax. Owesifazane unobude obungu-10 mm, umzimba wakhe ulingana nepea elikhulu, futhi ukhulu kakhulu kunowesilisa (ngokwesilinganiso ngo-3-4 mm). Insikazi inombala omnyama onomugqa obomvu, kwesinye isikhathi ophazanyiswayo ebusweni bomgogodla besisu esingenhla.
Amabala abomvu amise okwe-hourglass ayabonakala ohlangothini lwe-ventral. Insikazi esencane inezimpawu ezengeziwe ezimhlophe esiswini, ezinyamalayo lapho isicabucabu sikhula. Owesilisa uvame ukuba nsundu ngokukhanyayo ngombala onomugqa obomvu ngemuva nezindawo ezikhanyayo ohlangothini olungaphakathi kwesisu, ezingabonakali kakhulu kunesowesifazane. Owesilisa ugcina ukumakwa okumhlophe ohlangothini lomgogodla wesisu kuze kube mdala. Isicabucabu esibomvu sinemilenze emincane nezindlala ezinobuthi.
Ukukhiqizwa kabusha kwesicabucabu esibomvu emuva.
Izicabucabu ezibomvu zingakhwelana noma ngasiphi isikhathi sonyaka, kepha imvamisa phakathi nezinyanga zasehlobo lapho amazinga okushisa ephakeme. Abesilisa abaningana bavela kuwebhu yowesifazane omkhulu. Bayancintisana, kaningi kuyabulala, ukushada, isikhathi sokuqomisana sithatha cishe amahora amathathu. Kodwa-ke, owesilisa oholayo angashesha lapho kuvela amanye amaduna.
Uma isicabucabu esiphikelelayo sisondela kowesifazane ngokushesha okukhulu, khona-ke sidla owesilisa nangaphambi kokukhwelana.
Ngesikhathi sokuhlangana, isidoda singena esithweni sangasese sowesifazane futhi sigcinwa kuze kufike amaqanda, kwesinye isikhathi kuze kube yiminyaka emibili. Ngemuva kokukhwelana, isicabucabu asiphenduli kwabanye abafakizicelo kanti ama-80% wabesilisa akakwazi ukuthola umlingani. Insikazi iba namaphakethe amaqanda amaningana, anamasaka amaqanda angaba yishumi, ngalinye liqukethe amaqanda angama-250. Amaqanda amhlophe abekwa kubulembu, kodwa ngokuhamba kwesikhathi aba nsundu.
Isikhathi sokuthuthukiswa sincike ekushiseni, izinga lokushisa elilungile libhekwa njenge-30 ° C. Izicabucabu zivela ngosuku lwama-27 kuya ku-28, zisuka ngokushesha endaweni kamama, ngosuku lwe-14 zisakazeka kuwebhu ngezindlela ezihlukile. Izinsikazi ezisencane ziyakwazi ukuzala ngemuva kwezinsuku eziyi-120, ezesilisa ngemuva kwezinsuku ezingama-90. Abesifazane baphila iminyaka engu-2-3, kanti abesilisa cishe izinyanga eziyi-6-7.
Ukuziphatha kwesicabucabu esibomvu emuva.
Izicabucabu ezibomvu emuva ziyimfihlo, ama-arachnid asebusuku. Bacasha ezindaweni ezomile ngaphansi kwama-awning, ezindlini ezindala, phakathi kwezinkuni ezibekiwe. Izicabucabu zihlala ngaphansi kwamatshe, izingodo noma phakathi kwezitshalo eziphansi.
Njengezicabucabu eziningi, abesifazane baluka izindwangu ezihlukile ezelukwe ngemicu eqinile; abesilisa abakwazi ukudala amanetha okubamba. Isicabucabu sewebhu sibonakala ngofeleba ongajwayelekile. Izicabucabu ezibomvu emuva zihlala zinganyakazi ngemuva kufeleni isikhathi esiningi. Yakhiwe ngendlela yokuthi izicabucabu zizwe ukudlidlizela okwenzeka lapho isisulu siwela ogibeni.
Phakathi nezinyanga ezibandayo zasebusika eJapane, izicabucabu ziyahlanya. Lokhu kuziphatha akukaze kubhekwe kunoma iyiphi enye ingxenye yomhlaba lapho kuhlala lezi zigcawu.
Izicabucabu ezinemibala ebomvu yizilwane ezihlala phansi futhi zikhetha ukuhlala endaweni eyodwa. Izicabucabu ezincane zihlala ngosizo lwentambo yesicabucabu, ethathwa ukuhamba komoya futhi iyiswe ezindaweni ezintsha zokuhlala.
Izicabucabu ezibomvu zisebenzisa amamaki abomvu ku-carapace ukuxwayisa izilwane ezidliwayo ngemvelo yazo enobuthi. Kepha akumangazi nakancane ukuthi izicabucabu ezinobungozi ezinjalo zinezitha emvelweni ezihlasela futhi zidle izicabucabu ezinobuthi. Lezi zilwane ziyizicabucabu ezinomsila omhlophe.
Ukudla kwesicabucabu esibomvu emuva.
Izicabucabu ezibomvu zibulala izinambuzane futhi ziyizisulu zezinambuzane ezincane ezibanjwe kwiwebhu yazo. Futhi kwesinye isikhathi babamba izilwane ezinkulu ezibanjwa kubulembu bobulembu: amagundane, izinyoni ezincane, izinyoka, izibankwa ezincane, amakhilikithi, amabhungane kaMay, namabhungane awela. Izicabucabu ezinombala obomvu ziphinde zintshontshe inyamazane ebanjwe enetheni lokucupha ezinye izicabucabu. Babekela izicubu izicupho ezihlukile. Ebusuku, abesifazane bakha izintambo zesicabucabu eziyinkimbinkimbi ezihamba nhlangothi zonke, kuhlanganise nokuzinamathela ebusweni bomhlabathi.
Ngemuva kwalokho izicabucabu ziyasukuma zilungise intambo enamathelayo, ziphinda isenzo esinjalo kaningana, zakha izingibe eziningi, isisulu esibanjiwe sikhubazekile ngoshevu futhi sibhajwe ngobulembu.
Isicabucabu esibomvu singenye yama-arachnids ayingozi kakhulu.
Izicabucabu ezibomvu emuva zingesinye sezicabucabu eziyingozi kakhulu e-Australia. Izinsikazi ezinkulu zivame ukuluma ngesikhathi sehlobo nasekupheleni kosuku lapho amazinga okushisa ephezulu futhi izicabucabu zisebenza kakhulu. Izicabucabu ezinemibala ebomvu zingalawula inani lobuthi elizifaka kumjovo wazo. Ingxenye eyinhloko yobuthi yobuthi yinto i-α-latrotoxin, umphumela wayo onqunywa ivolumu yomjovo.
Abesilisa baletha ukulunywa okubuhlungu, okunobuthi, kepha cishe u-80% wokulunywa awunawo umphumela olindelekile. Ezimweni ezingama-20%, ukuzwa okubuhlungu kuvela endaweni yokungenisa ushevu kuphela ngemuva kwamahora angama-24. Ezimweni ezibucayi kakhulu, ubuhlungu buhlala isikhathi eside, bese kuba nokwanda kwama-lymph node, ukukhuphuka kokujuluka, ukukhuphuka kwenhliziyo, kwesinye isikhathi ukuphalaza, ukuphathwa ikhanda nokuqwasha. Izimpawu zobuthi zingaqhubeka izinsuku, amasonto, noma izinyanga. Lapho kuvela izimpawu ezinzima, i-antidote inikezwa nge-intramuscularly, kwesinye isikhathi imijovo eminingi.
Isimo sokongiwa kwesicabucabu esibomvu emuva.
Isicabucabu esibuyiselwe emuva okwamanje asinaso isimo esikhethekile sokongiwa kwemvelo.
