Chav kawm ntawv Kab

Lub ntiaj teb no ntawm kab paub rau cov txiv neej rau ib tug ntev lub sij hawm. Ntxiv rau lub qhov tsua paintings (nees nkaum txhiab xyoo dhau los) dluab twb pom bees thiab yug me nyuam rau cov cab cocoons nyob rau hauv Tuam Tshoj koom nyob rau hauv tsib txhiab xyoo dhau los. Nyob rau hauv Ancient tim lyiv teb chaws, tus dawb huv lub cim ntawm uas yog tus scarab kab, fwm inscriptions ntawm kooj.

Kab chav kawm ntawv yog ib qho ntawm feem ntau heev heev. Yog hais tias peb ua tib zoo xyuas hauv lub cev ntawm ib tug kab, nws yog tau mus soj ntsuam ib tug ntshiab division: lub taub hau, qab plab mog, plab. Ib tug khub ntawm antennae, uas yog cov tsis totaub, ib khub ob lub qhov muag thiab lub qhov ncauj qhov chaw muaj nyob rau ntawm lub taub hau. Txhua lub peb thoracic feem endowed nrog ib tug khub ntawm ob txhais ceg. Lub nraub qaum ntawm ob theem no yog muab nrog ib tug thiab tej zaum ob khub uas muaj tis. Plab mog tej lub nrws, sawv cev rau hauv chav kawm ntawv ntawm cov kab, nws yog tseem muab faib mus rau hauv feem, uas yuav ua tau los ntawm rau mus rau kaum ob.

Hypodermis uas yog nyob tam sim ntawd hauv qab no lub chitin uas npog lub cev los ntawm sab nraum, yog ua homogeneous hlwb, ib txhia ntawm lawv yog cov glandular. Chitin muaj ib tug feature tsis stretch, xyoo ib tug laus mus rau ib tug tshiab txheej, i.e. muaj yog molting txheej txheem. Qhov no tus txheej txheem yog ib qho tseem ceeb heev rau txoj kev loj hlob ntawm cov tshuaj tua kab.

Class Kab txawv complex ncauj, muaj raws ntawm sab sauv thiab sab puab tsaig, lub Upper thiab qis daim di ncauj thiab tus nplaig, uas yog chitinous protrusion pem teb ntawm lub qhov ncauj.

Ncauj ntawm kab yog ib yam uas muaj ntau hom kab gnawing nws, yoov - licking, los ntawm butterflies - ib co kab, thiab yoov tshaj cum thiab dev mub - tho-ib co kab.

ua pa nrog cev lub raj cua, lawv muab ntaub so ntswg nrog oxygen. Mus txog rau kaum officers ntawm kev ua pa qhov muaj nyob rau ntawm lub sab ntawm cov tshuaj tua kab lub cev.

Tsis loj hlob ntawm lub circulatory system txuam nrog ib tug kev qauv ntawm cov pa system. Lub paj hlwb yog, nyob rau hauv tsis tooj, muaj ib theem siab ntawm kev loj hlob. Muaj peb kev sib cais "hlwb" - pem hauv ntej, nruab nrab thiab nram qab lub.

Creatures sawv cev rau lub chav kawm ntawv ntawm cov kab, muaj zoo-tsim tsis totaub. Sensitive cov plaub mos mos, muaj tag nrho cov thoob lub cev, muaj nuj nqi raws li tactile kabmob, thiab antennae thiab mandibular palps yog olfactory kabmob. Nrog hais txog lub rooj sib hais, uas tej hom ntawm cov tshuaj tua kab, kooj, piv txwv li, kev ntes cov suab ntawm peb khub ntawm ob txhais ceg. Nws nyob ntawm no, nyob rau hauv ob txhais ceg, thiab muab tso rau hauv lub nruab nrog lub rooj sib hais. Lub qhov muag ntawm kab ntawm cov hoob kawm no yuav ua tau yooj yim los yog txoj. Thaum muaj tus sib haum xeeb hniav ntawm lub qaum tis ntawm tus ncej puab ntawm lub hind nqua, muaj ib tug yam ntxwv rau ib qho kab suab.

Raws li ib tug txoj cai, kab coj ib tug neeg ib tug ntau ntawm teeb meem. Lawv vectors thiab pathogens ntawm ntau yam kab mob. Vim hais tias zaum tau ntev lawm koom nyob rau hauv txoj kev tshawb no ntawm no hauv chav kawm ntawv. Cov science uas kawm kab yog hu ua Entomology. Niaj hnub no, nws yog tseem ceeb nyob rau hauv ib tug nyias muaj nyias ib ceg ntawm biology thiab tsim qhov kev lag luam tsis tshua muaj neeg sai heev.

Entomology yuav tau muab faib mus rau ntau cov chaw: general Entomology, kev kho mob, forestry, kho tsiaj, ua liaj ua teb. Tib zaj dab neeg nrog apiculture thiab sericulture - lawv zoo li zoo hais txog Entomology.

Nyob rau hauv Feem ntau, txhua cov kev taw qhia ntawm no science nws muaj nws tus kheej specifics. Piv txwv li, kev Entomology tau kawm lub ntsiab nta ntawm cov qauv ntawm cov kab, ob sab hauv thiab sab nraud, txoj kev tshawb no ntawm lawv txoj kev ntawm lub neej, txoj kev loj hlob thiab tu tub tu kiv, raws li zoo raws li lub cim ntawm kev sib raug zoo nrog cov ib puag ncig.

Kab kab thiab pollinating kab tuaj mus rau cov xim ntawm ua liaj ua teb Entomology. Zaum no tsim cheeb tsam no raws li kab kev tswj, nyob rau hauv thiaj li yuav txo tau cov kev puas tsuaj ua rau ua liaj ua teb.

Kab chav kawm ntawv yog loj loj thiab ntau haiv neeg. Nws cov neeg sawv cev nyob qhov txhia chaw: cov av thiab cov nroj tsuag, huab cua thiab dej, raws li zoo raws li lub roob thiab lub lowlands, deserts thiab daus - tag nrho cov no yog lawv ib txwm nyob.
