Chifukwa chiyani ntchentche zimasilira miyendo yawo: chinsinsi cha chiwembu cha Diptera

Momwe miyendo ya ntchentche imapangidwira komanso kuti ndizosiyana bwanji

Ntchentche imayeretsadi thupi motere, makamaka miyendo. Koma iye samachita izi chifukwa cha ukhondo wambiri, koma chifukwa cha thupi lake.

Kodi ntchentche zimagwiritsa ntchito bwanji miyendo yawo?

1. Chifukwa cha miyendo yodabwitsa yotereyi, arthropod imasunga bwino galasi, galasi ndi malo ena aliwonse osalala.
2. Ikhoza kusuntha mosavuta padenga ndi makoma mozondoka ndikulowa m'makona osafikirika kwambiri a chipindacho.
3. Kuonjezera apo, tizilombo timagwiritsira ntchito ma bristles omwe ali pa pulvilles monga chiwalo chokhudza ndi kununkhiza, kudziwa kukoma ndi kukongola kwa mankhwala.
4. Ntchentche zikamauza ntchentche kuti yatera pa chinthu chodyedwa, munthuyo amachilawa ndi lilime lamtundu wa libella pad. Ndiko kuti, choyamba tizilombo timayesa chakudya ndi mapazi ake, ndiyeno pokhapo ndi proboscis ndi masamba oyamwa.

N'chifukwa chiyani ntchentche imapukuta miyendo yake: zifukwa zazikulu

Ikamalawa komanso kuyenda motere, miyendo ya ntchentcheyo imasonkhanitsa msanga fumbi ndi dothi lomwe limaswa kumatira pamwamba.

Pofuna kukwawa mosaletseka, tizilombo timakakamizika kuyeretsa nsonga za miyendo yake kuchokera ku tinthu tating'ono tachilendo tambiri, zomwe zimachititsa kuti katulutsidwe kamene kamatulutsa kuchokera ku chakudya ndi lipids.

Choncho amasunga ziwalo zofunika kuti zigwire ntchito. Njira yonse yaukhondo imakhala ndi magawo angapo. Choyamba, ntchentchezo zimatsuka miyendo yawo yakutsogolo, kenako zimatsuka mitu yawo ndi miyendo yakumbuyo ndi zikhadabozi, ndipo pamapeto pake zimapukuta mapiko awo.

Chimachitika ndi chiyani ngati mutsitsa miyendo ya ntchentche

Kuyang'ana m'dera lomwe kachilomboka kamasunthira, munthu amatha kuwona zowoneka ngati zofiirira zomwe zimawonetsa malo a outgrowths-pulvilles. Akatswiri a entomologists apeza kuti amapangidwa ndi triglycerides.

Ngati mutachotsa mafuta ku miyendo ya ntchentche, kuwamiza mwachidule mu hexane, kuyenda kwa arthropod sikungatheke.

Ndi matenda owopsa otani omwe ntchentche zimanyamula pamapazi awo?

Ngakhale kuti miyendo imayeretsedwa nthawi zonse, ntchentche ndizomwe zimanyamula matenda a parasitic ndi matenda opatsirana. Chifukwa cha kafukufuku, mabakiteriya okwana 6 miliyoni adapezeka pamtunda wa munthu mmodzi yekha, komanso 28 miliyoni m'matumbo ake.

Ndikoyenera kuzindikira zimenezo m'madera okhala ndi ukhondo, mpaka 500 miliyoni tizilombo titha kukhala pa ntchentche. Tizilombo tating'onoting'ono timafika m'miyendo ya tizilombo kuchokera ku zinyalala zamagulu ndi kuchoka kwa iwo kupita ku chakudya. Munthu akamadya chakudya chimenechi amadwala matenda enaake kapena amamwa poizoni. Mwa matenda owopsa omwe amatengedwa ndi ntchentche ndi awa:

More tizirombo pa mapazi awo kufalitsa mazira a nyongolotsi, matenda amene amapezekanso kudzera chakudya. Zatsimikiziridwa kuti zinali ntchentche zomwe nthawi zina zidakhala magwero a miliri yayikulu.

Mwachitsanzo, m’zaka za m’ma 112 ku Russia anayambitsa matenda okwana XNUMX a jaundice, ndipo ku Cuba ndi ku Puerto Rico pa nthawi ya nkhondo ya Aspanya ndi America anayambitsa matenda a kamwazi ndi typhus.

Ngakhale panopo, matenda ochititsa khungu a trachoma, oyambitsidwa ndi mitundu ina ya ntchentche, amakhudza anthu pafupifupi 8 miliyoni chaka chilichonse.
