Intwala yehagu yeyona inkulu kwiintwala zesilwanyana kwaye ichitha ubomi bayo beeveki ezine kwisikhumba sehagu.
Isifundo se-Morphology
Intwala yehagu ( Haempatopinus suis ) sisinambuzane esingenamaphiko esine-4–6 mm ubude esinomzimba wesithathu (intloko, ithorax, isisu) kunye neendawo ezintandathu ezichaziweyo, nganye ineenzipho eziphuhlileyo eziphelweni zokubambelela kumamkeli.. Intloko incinci kunecandelo le-thoracic elilandelayo kwaye inee-eriyali ezicacileyo ezibonakalayo emacaleni. Ngaphakathi kwentloko kukho iproboscis. Isisu, esahlulwe sibe ngamacandelo amaninzi, sineepleyiti ze-chitin ezibukhali emacaleni, ezibizwa ngokuba wezomthetho iiplate.
Amakhaya
Intwala yehagu ingqongqo yokusingatha-indawo ethile kwaye ihlala njenge ectoparasite kuphela kwihagu. Ayinakwenzeka kwezinye izilwanyana nakubantu.
Umnqa wobomi
Lonke uphuhliso lwentwala yehagu lwenzeka kwihagu. Amaqanda agqunyiweyo ( oonomoyi) ancanyatheliswe ezinweleni ngento ebolileyo. Umjikelo wonke wophuhliso uthatha malunga neeveki ezine.
Iintwala zehagu zifunxa igazi. Iintwala eziwe ngumamkeli zingaphila kuphela kwindawo engqongileyo ixesha elifutshane (malunga neentsuku ezimbini kwiqondo lobushushu begumbi). Iintwala zisasazwa ngokudibana ukusuka ehagwini ukuya kwihagu.
ubungqina
Iintwala ezinkulu zinokubhaqwa ngqo kwiihagu. Ukwenzela le njongo, amalungu anolusu olubhityileyo kufuneka ahlolwe ngokukodwa (umz. umphezulu ongaphakathi weendlebe, amathanga, namakhwapha). Ukubona oonomoyi, iisampulu zeenwele zithathwa kwaye zihlolwe phantsi kwe-microscope.
Umfanekiso weklinikhi
Iintwala zibangela ukurhawuzelelwa kunye nokutshintsha kwesikhumba (ukwakheka kwamaxolo namaqweqwe), kwaye ukuphuma kwegazi kungakhokelela kwi-anemia, ngakumbi kumantshontsho eehagu nakwizilwanyana ezincinci. Iqondo eliphezulu lohlaselo lweentwala lukhokelela ekusebenzeni okucuthiweyo kunye nokunciphisa ubunzima bomzimba.
Prophylaxis/unyango
Unyango lwenziwa ngezinambuzane ezilungele iihagu. Ekubeni uninzi lwamayeza okubulala izinambuzane lungasebenzi ngokuchasene noonomoyi, unyango kufuneka luphindwe emva kweeveki ezimbini.
Ukuhlaselwa kweentwala yenye yezinto ezibizwa ngokuba “zizifo ezibangelwa zizifo”, oko kukuthi, izinto ezikhuthaza ukuhlaselwa kweentwala (umzekelo, ukunqongophala kwevithamin kunye neeminerali, ukungabikho kokukhanya, ukuxinana kwezindlu ezininzi, ukungondleki) kufuneka kupheliswe.
Sele uyazi?
- Njengentloko yomntu kunye nentwala yomzimba ( I-Pediculus humanus ), intwala yehagu yeyohlobo lweentwala zokwenyani (Anoplura)
- Izigaba zombungu wentwala yehagu ziyefana neentwala ezindala, kukho umahluko omncinane kuphela wobukhulu, ubungakanani bomzimba, kunye neebristles.
- Intwala yehagu yeyona ntwala inkulu kwaye inokubonwa ngeliso lenyama.
- Iihagu azinalo uhlobo lwazo lwentwala ezilumayo.
- Izilwanyana ezincinci zihlala zihlaselwa kakhulu ziintwala.
- Iintwala zehagu zithathwa ngokuba ngabathwali bomkhuhlane wehagu kunye nerhagu.
Umbuzo obuzwa rhoqo
Ingaba ihagu icocekile?
Zizilwanyana ezicocekileyo kakhulu, zihlula ngokungqongqo indawo yazo yokulala "kwindlu yangasese" yazo kwaye zigweme ukungcolisa indawo yokutya. Kuba zingakwazi ukubila, iihagu ziyabuva ubushushu. Balawula ubushushu bomzimba wabo ngokuhlamba, ukuziqengqa, okanye ukubhuqabhuqa.
Ingaba iihagu zineentwala?
Iintwala zehagu zifunxa igazi. Iintwala eziwe ngumamkeli zingaphila kuphela kwindawo engqongileyo ixesha elifutshane (malunga neentsuku ezimbini kwiqondo lobushushu begumbi). Iintwala zisasazwa ngokudibana ukusuka ehagwini ukuya kwihagu.
Zivela phi iintwala zehagu?
Ingaba iintwala zehagu zingagqithiselwa ebantwini?
Iihagu zifumana iintwala kwezinye iihagu. Iintwala zehagu zizinto ezikhethekileyo kwaye azinakuphila kuzo naziphi na ezinye izilwanyana okanye abantu.
Uzilawula njani iintwala zehagu?
Iintlobo ngeentlobo zeekhompawundi zilawula ngempumelelo iintwala kwiihagu, kuquka iipyrethrins ezihlanganisiweyo; iipyrethroids; i-organophosphates phosmet, i-coumaphos, kunye ne-tetrachlorvinphos; kunye ne-macrocyclic lactones ivermectin kunye ne-doramectin.
Yintoni imange ezihagwini?
Imange ezihagwini yenziwa yi Sarcoptes scabiei var. i-suis (intshontsho lengcwaba). I-Sarcoptes mites ibonakala ingqukuva kwaye inemilenze emifutshane emine, ayiphumeli ngaphaya komzimba, kunye nezenzi ezinde, ezingadityaniswanga kunye neepedicel ezimile okwentsimbi.
Kutheni iihagu zizikrwela?
I<em>mange yehagu ibangela ukurhawuzelelwa okugqithisileyo: izilwanyana ziyazizonwaya kwaye zithwaxwe ngamathumba asasazeke kuwo wonke umzimba. Ngenxa yokuba izilwanyana aziphumli, ukusebenza kwazo kuyancipha.
Yintoni i-erysipelas kwiihagu?
I-Erysipelas sisifo esosulelayo esibangelwa yintsholongwane i-Erysipelothrix rhusiopathiae. Iihagu zichaphazeleka ngakumbi, kodwa kunye neegusha kunye neenkukhu, amatyeli amaninzi amahashe, iinkomo kunye neentlanzi. Kuba iyi-zoonosis, abantu nabo banokuchaphazeleka.
