Kab laum yog ib tug ntawm cov kab laus tshaj plaws paub, vim muaj cov pob txha seem uas muaj hnub nyoog tshaj 300 lab xyoo thiab, nyob rau hauv tag nrho cov. lub sij hawm no, lawv tsis tau hloov ntau.

Tam sim no, muaj ntau hom kab laum yog ze ze rau tib neeg kev ua si thiab nws cov pov tseg, yog li nws yog ib qho uas pom lawv, tshwj xeeb tshaj yog nyob rau hauv lub caij ntuj sov, thaum tshav kub ntawm qhov chaw ua rau lawv tawm ntawm lawv qhov chaw nkaum. Tsis xav tias koj tau ntshai thaum koj hla cov kab no.

Nyob hauv tsab xov xwm no ntawm peb lub xaib peb yuav pom tias txhua tus kab laum ya tau tiag tiag los yog vim li cas kab laum ya tuaj rau koj.

kab laug sab

The taxonomy is the branch of biology lav ris rau kev npaj phylogenetic tsob ntoo ntawm lub neej los ntawm taxa. Tom ntej no, peb yuav piav qhia txog lub taxonomy ntawm kab laum mus rau Order taxon txij thaum, tom qab ntawd, nws ceg mus rau ob peb tsev neeg raws li hom:

  • Domain: Eukarya. Vim yog cov kab mob ntau lub cev uas nws cov nuclei muaj tseeb.
  • Animalia Kingdom . Rau kev muaj peev xwm locomotion, pub noj los ntawm kev noj, rov tsim dua kev sib deev, siv cov pa oxygen hauv pa thiab muaj kev loj hlob ntawm embryonic.
  • Subkingdom: Eumetazoa. Rau kev nthuav tawm cov ntaub so ntswg xws li epidermal lossis cov ntaub so ntswg sib txuas. Kev loj hlob ntawm lub paj hlwb.
  • Phylum: Arthropoda. Invertebrate tsiaj nrog exoskeleton thiab articulated appendages (ceg, kav hlau txais xov los yog lub puab tsaig).
  • Superclass: Hexapoda. Lub cev muab faib ua tagmata: taub hau, thorax thiab plab.
  • Class: Insect. Arthropods tus yam ntxwv muaj ib khub kav hlau txais xov, 3 khub ob txhais ceg thiab ob khub tis, uas tej zaum yuav raug txo los yog tsis tuaj.
  • Subclass: Pterygota. Lawv nthuav tawm nyob rau hauv lub thib ob thiab thib peb tagma ntawm lub thorax ob khub ntawm tis, uas yog, lawv yog tis kab.
  • Underclass: Neoptera. winged kab uas thaum so kom lawv tis ze rau lub cev.
  • Order: Blattodea. Kab laum zoo li kab ntawm
  • Tsev Neeg: Blaberidae, Blattellidae, Blattidae, Cryptocercidae, Polyphagidae thiab Nocticolidae..

cev xeeb ceem ntawm kab laum

Cov yam ntxwv tseem ceeb ntawm pawg tsiaj no yog lawv lub cev flattened zoo heev. Nyob ntawm cov hom, muaj kab laum me dua li ib centimeter nyob rau hauv cov cheeb tsam arctic thiab loj dua 7 centimeters nyob rau hauv cov cheeb tsam kub tshaj plaws ntawm lub ntiaj chaw.

Zoo tag nrho cov no yog dub xim , xim av los yog dub. Lub exoskeleton yog du, tsis tshua muaj setae lossis hnov cov plaub hau, txawm hais tias ob txhais ceg feem ntau muaj kev tiv thaiv qaum. Lub thorax muaj ib tug heev tsim thiab flattened proton (thawj ntu ntawm lub thorax; dorsal) uas npog lub taub hau. Lawv muaj legs long thiab tsim tawm rau haiv neeg.

Lawv muaj lub taub hau orthognathic thiab txawm tias lub taub hau hypognathic, uas yog, lub qhov ncauj tau coj mus rau hauv qab thiab lub taub hau tau muab tso rau ntawm lub cev. Lawv muaj ib khub ntev heev antennae. Lub qhov muag yog qhov sib xyaw, loj thiab teeb tsa tom qab ntawm lub taub hau. Lawv kuj muaj khub thiab lateral ocelli (sensory organs). Lawv muaj chewing lub qhov ncauj nrog lub puab tsaig ruaj khov, lawv cov khoom noj muaj ntau yam sib txawv.

Kab laum kab los yog tom?

Kab laum tsis txhob tom vim lawv tsis muaj kab mob rau nws, tab sis lawv puas tom? Lawv muaj peev xwm thiab, ntxiv rau, lawv qhov tom muaj zog heev, txij li thaum lawv noj yuav luag txhua yam, suav nrog plaub hau, ntawv lossis kua nplaum, txawm tias lawv nyiam cov zaub mov. decomposing organic teeb meem, nplua nuj nyob rau hauv qab zib thiab rog.

. Lawv feem ntau ua nyob rau hauv qhov chaw uas cov khoom khib nyiab khaws cia, xws li ko taw, rau tes lossis plaub muag.

Kab laum muaj tis thiab tsis muaj tis

Cov kab no muaj nyob rau hauv subclass pterygota, uas yog tus cwj pwm los ntawm cov kab nrog tis, tab sis tsis yog txhua tus kab laum yaFeem ntau ntawm Blatodeos muaj tis, tab sis ib txhia, nyob rau hauv cov neeg laus lub xeev, kom lawv txo los yog tsis tuaj, feem ntau yog cov poj niam. Qhov no yog lub npe hu ua neoteny, uas yog, muaj cov cim menyuam yaus (tsis muaj tis) hauv lub xeev laus. Lwm qhov zoo tshaj plaws neoteny yog "tus me nyuam" ntsia ntawm cov neeg laus dev.

Kab kab feem ntau muaj ob tis tis Cov kab no yog kab laum. Cov tis ntawm thawj khub, hu ua tegmites, yog tawv (hardened nyob rau hauv tsos) thiab, thaum so, sab laug npog sab xis. Ob khub tis yog chaw nyob hauv thawj khub thaum tus tsiaj tsis ya. Tag nrho cov tis muaj zog innervated.

  • Cov kab laum kab dav dav tshaj plaws hauv Spain: Blattella germanica (German lossis kab laum daj), Periplaneta americana (Asmeskas lossis kab liab liab) thiab Periplaneta australiasea (Australian cockroach).
  • Cov kab laum uas tsis muaj kab laum ntau tshaj plaws hauv Spain: Blatta orientalis (dub, oriental, hom lossis Old World cockroach).

Txawm tias lawv muaj tis los, kab laum yaim zoo li glide dua ib lub davhlau tiag, yog li peb ntsib kab laum ntawm phab ntsa, nws ntshai thiab pom tsis muaj txoj kev khiav ntawm ko taw, nws yuav sim ya. Raws li lawv tswj tsis tau lub davhlau zoo heev, qhov yooj yim tshaj plaws yog tawm ntawm phab ntsa nrog ib tug perpendicular trajectory, ces kab laum yuav tshwm sim ya rau peb thiab, nyob rau hauv ntau zaus, nws yuav xaus rau kev sib tsoo nrog peb lub cev nyob rau hauv ib txoj kev uas tsis tau npaj tseg.

flight Mechanism

Txhua tus tis ntawm kab laum, thaum ya mus, ua ib qho txav mus rau hauv cov duab ntawm "8"Nws nqis mus thaum lub flapping thiab nce mus thaum lub downcast. Qhov kev txav no yog lub luag haujlwm rau kev ua ntej ntawm tus tsiaj thaum lub sijhawm ya mus, kev nqis los ntawm tis yog dab tsi muab lub zog.

Yog tias tus tsiaj muaj peev xwm tswj tau lub kaum sab xis uas nws txav nws lub tis, nws yuav muaj kev tswj hwm nws lub davhlau, suav nrog kev ya rov qab. Tsis yog kab laum, uas tsuas yog ya mus tom ntej.

Ntawm qhov tod tes, nws tau qhia tias ntug ntawm lub tis ua rau muaj zog heev kiv cua zoo li cua uas ua rau nce siab.

Tsis zoo li cov noog ya, kab tsis muaj cov cim ya hauv lawv lub hlwb. Es tsis txhob, lawv muaj receptors los yog sensory organ nyob rau hauv lub thorax thiab tis. Qhov nyiaj tshuav thaum ya davhlau yog ua tiav los ntawm lwm yam sensory receptors nyob rau hauv lub taub hau.

Kab mob kis los ntawm kab laum

Kab laum tuaj yeem kis tau los yog natural reservoir of pathogens Hnub lawv nyob hauv qhov tsaus ntuj, tsaus ntuj thiab sov, nrog rau qib siab. Kev kis kab mob, xws li cov kav dej phwj tuaj, cov kav dej septic lossis cov kav dej phwj tuaj, thiab thaum tsaus ntuj lawv tawm thiab taug kev ywj pheej hauv cov txee, pantries, chav ua noj, thiab lwm yam.

Nws ob txhais ceg, plab zom mov thiab integument (tawv nqaij) yog npog los ntawm ntau txhiab tus kab mob thiab lwm yam kab mob(txawm yuav ua phem rau kev noj qab haus huv los yog tsis yog). Kev kis ntawm cov kab mob no tshwm sim thaum kab laum regurgitates cov zaub mov, los ntawm kev sib cuag nrog nws cov extremities los yog poob.

  • Bacterial Kab mob Kab mob kis tau los ntawm kab laum: kab mob plab, mob plab, mob plab, mob npaws, kab mob plague, gangrene, leprosy, Asiatic cholera, meningococcal meningitis, pneumonia, diphtheria, brucellosis, glanders, anthrax, tetanus thiab tuberculosis.
  • Kev kis ntawm helminths (worms): Oxyspirura mansoni, uas tawm tsam lub qhov muag ntawm nqaij qaib, Moniliformis moniliformis thiab Moniliformis dubius.
  • Kev kis ntawm protozoa: Balantidium coli, Entumoeba histolytica, Giardia intestinalis, Toxoplasma gondii and Trypanosoma cruzi.
  • Kev kis ntawm fungi ntawm plab hnyuv: Mortierella spp., Aspergillus spp., Candida albicans thiab lwm yam.
