Txhua hom tsiaj uas ua rau tsiaj ntiaj teb tau tsim lawv tus kheej cov tswv yim kev yug me nyuam, yoog kom lav lawv lub neej nyob mus ib txhis. Cov ntaub ntawv ntawm kev yug me nyuam no zoo sib xws rau ntau yam, xws li cov yam ntxwv ntawm lub cev thiab lub cev nqaij daim tawv ntawm txhua pab pawg, ntxiv rau cov xwm txheej ntawm qhov chaw nyob, uas tsis muaj qhov tsis txaus ntseeg muaj feem cuam tshuam rau cov txheej txheem kev xeeb tub.
Ib pawg tsiaj uas muaj cov tswv yim kev loj hlob kom muaj kev vam meej ntawm ntau tus neeg hauv txhua lub voj voog kev loj hlob yog kab, thiab hauv kab lus no peb xav tham tshwj xeeb txog yoov tshaj cum yug thiab yug li cas , nrog rau piav qhia tias yoov tshaj cum nyob ntev npaum li cas tom qab tshuaj xyuas tag nrho lawv lub neej.
Type of yoov tshaj cum
Mosquitoes, also known as yoov tshaj cum, muaj kev sib deev sab hauv, kom cov txiv neej tso cov phev ncaj qha mus rau poj niam, leej twg yuav sau. nws nyob rau hauv lub spermatheca thiab yuav siv nws mus tas li fertilization ntawm ovules. Ib yam uas xav paub thaum lub sij hawm yug me nyuam ntawm yoov tshaj cum yog qhov kev sib hais plaub tshwm sim hauv cov kab no, uas peb yuav pom meej nyob rau hauv ntu tom ntej.
yoov tshaj cum yug li cas?
, ntawm qhov tod tes, lwm hom tsis tsim cov pab pawg no, tab sis kev sib cuag tshwm sim ncaj qha ntawm ob tus neeg. Thaum cov swarms tshwm sim, cov poj niam mus txog thiab xaiv tus txiv neej rau copulation, uas feem ntau yuav tshwm sim ntawm pawg thiab yuav kav tsawg tshaj li ib feeb. Kawm txog txhua hom yoov tshaj cum nyob rau lwm tshooj no.
txiv neej muaj peev xwm inseminate ob peb poj niam, hos lawv yog monogamous, yog, lawv tsuas yuav nrog ib tug txiv neej xwb. Qhov no tshwm sim vim hais tias tom qab inseminating nws, tus txiv neej secretes ib yam khoom uas kev sib deev inactivates tus poj niam rau tag nrho nws lub neej, uas nws yuav tsis tau txais lawm. Tom qab fertilization, cov txiv neej tuag nyob rau hauv ob peb hnub, txawm li cas los xij, cov poj niam yuav tsum pub kom tau txais cov as-ham thiab txuas ntxiv nrog kev loj hlob ntawm cov qe; Nyob rau hauv cov ntaub ntawv ntawm hematophagous, lawv yuav ncaj qha mus nrhiav ib tug neeg los yog tsiaj mus rho tawm cov ntshav tsim nyog thiab oogenesis yuav muaj.
yoov tshaj cum yug li cas?
yoov tshaj cum nteg qe, uas yav tas los fertilized los ntawm cov txiv neej nyob rau hauv tus poj niam. Tom qab pub mis kom zoo, tus poj niam pib txheej txheem ntawm oogenesis lossis kev loj hlob ntawm cov qe thiab nteg yuav tshwm sim ntawm ob thiab plaub hnub tom qab cov ntshav noj, nyob rau hauv cov ntaub ntawv ntawm hematophagous hom.
Tom qab ntawd, txoj kev loj hlob ntawm embryonic uas tshwm sim nyob rau hauv lub qe, nyob rau hauv lub zoo ib puag ncig tej yam kev mob, yuav tsim cov larvae ob mus rau plaub hnub tom qab oviposition Tom qab ntawd, theem menyuam yaus yuav tshwm sim, qhov chaw metamorphosis yuav tshwm sim kom tus neeg laus thaum kawg tshwm sim.
Yog li no, yoov tshaj cum nyob rau pawg holometabolous, uas yog, lawv muaj plaub theem: qe, larva, pupa thiab cov neeg laus, dhau los ntawm lawv tsim metamorphosis. Cia peb kawm ntxiv txog txhua theem no kom nkag siab zoo dua li yoov tshaj cum yug:
Phase 1: Qe
Ib tug poj niam muaj peev xwm pw ntawm 50 thiab 200 kwv yees li ntawm no, ntawm no peb tuaj yeem pom cov tswv yim zoo heev ntawm cov ovipositions, uas tsis ntseeg tau nrhiav los tsim cov neeg coob tshaj plaws. Qhov tseeb, qhov no yog ib qho peculiar yam ntxwv ntawm kab nyob rau hauv cov nqe lus ntawm lawv reproduction.
yoov tshaj cum muaj peev xwm nteg qe rau ntau txoj kev, txawm li cas los xij, cov txheej txheem no tuaj yeem muab faib ua peb txoj hauv kev:
- Nkauj hmoob da dej.
- In floating group on water.
- Nyob rau ntawm qhov chaw uas dej nyab ib ntus. Qhov kawg no suav nrog cov tsiaj uas tsim cov qe uas tuaj yeem tiv taus qhov tsis muaj dej rau qee qhov, tab sis thaum kawg xav tau, vim tias txhua tus larvae yog hom dej.
yoov tshaj cum nteg qe qhov twg? yoov tshaj cum yuav nteg lawv cov qe rau hauv , tsis muaj dej ntws loj, los yog nyob rau hauv substrate xws li av los yog nroj tsuag, uas zoo guarantees txoj kev loj hlob ntawm lawv. Txawm li cas los xij, thaum lawv ua li no hauv qhov kev xaiv kawg no, cov chaw no yuav tsum raug rau hauv qhov dej, vim tias, nyob rau hauv ib txoj kev uas yuav tsum tau, cov larvae xav tau cov dej ib puag ncig rau lawv txoj kev loj hlob thiab dhau mus rau theem pupal, tom qab uas cov neeg laus tshwm sim. muaj tus cwj pwm saum huab cua. Ntawm qhov tod tes, qee hom muab tso rau hauv dej nrog qee qhov dej ntws, tab sis lawv ua rau ntawm ntug dej lossis qhov chaw cov nroj tsuag muaj kev tiv thaiv.
Phase 2: larva
Mosquito larvae is characterized by being vermiform, that is, they have the looks of a worm. Raws li peb tau hais lawv yog cov dej nyob hauv tus cwj pwm thiab ua pa ncaj qha los ntawm huab cua. Nyob rau theem no lawv nquag noj, uas lawv tuaj yeem ua tsaug rau lawv lub puab tsaig, uas lawv khawb qhov chaw, lim dej los yog cov tsiaj nyeg ntawm lwm hom tsiaj, noj detritus, kab mob thiab txawm tias me me invertebrates.
Nyob rau theem no, qhov kub thiab txias plays lub luag hauj lwm txiav txim nyob rau hauv txoj kev loj hlob ntawm larva, txhua hom muaj ib tug zoo ntau yam hauv qab no uas tus neeg yuav tuag los yog mus rau hauv hibernation: saum toj no lawv ib txwm mus rau perish.
Phase 3: pupa
FORKS RAU LUB ZAUB NTXHAIS LOS NTAWM YAM NTXHAIS HEEV (tshwjxeeb tsis pub, tab sis tag nrho lub zog noj yog destined rau qhov tshwm sim ntawm anatomical thiab physiological hloov, uas ua rau ib tug neeg laus tag nrho txawv ntawm cov larva. Nyob rau theem no, lawv tsim kev ua siab ntev rau desiccation thiab txawm tias qee yam tshuaj lom neeg.
Nyob rau hauv qhov zoo tshaj plaws kub, kev loj hlob ntawm pupa yuav kav li ntawm ob mus rau tsib hnub. Thaum cov txheej txheem tab tom yuav xaus, tus pupa feem ntau tsiv thaum hmo ntuj mus rau qhov chaw uas muaj kev thaj yeeb nyab xeeb thiab tiv thaiv zoo li ua tau hauv dej, nws pib nqus cua ntau kom lub siab uas sib sau ua rau cov cuticle uas npog nws. Thaum kawg tuaj yeem tshwm sim.
Phase 4: Adult
Thaum nws tshwm sim, tus neeg laus yuav tsum tau qee lub sij hawm kom qhuav tag, tshwj xeeb tshaj yog cov tis, uas nws ua rau saum npoo dej, qhov twg nws kuj ua tiav tawv. Tom qab nruab nrab ntawm ib thiab ob hnub, cov neeg laus muaj kev sib deev paub tab, txawm hais tias nyob rau hauv cov poj niam txoj kev tshwm sim ntxov dua li cov txiv neej.

Mosquito Breeding Season
Ib puag ncig muaj kev txiav txim siab rau kev tsim cov yoov tshaj cum, kom cov Environmental conditions yog txiav txim siab rau kev tsim cov yoov tshaj cum, kom cov Environmental conditions yog txiav txim siab los tsim cov yoov tshaj cum, kom cov Environmental conditions yog txiav txim siab rau kev tsim cov yoov tshaj cum, kom cov Environmental condition is decisive for the reproduction ntawm yoov tshaj cum, yog li ntawv yam tseem ceeb rau cov kab no kom rov tsim dua tshiab. Hauv qhov kev nkag siab no, piv txwv li, hauv cov tebchaws uas qhov ntsuas kub qis heev thiab txawm tias ncav cuag 0 o C, thiab cov nag yuav raug raws caij nyoog, hom yoov tshaj cum uas nyob. Cov cheeb tsam no feem ntau mus dhau ib theem hu ua dipauseNov yoglub cev lub cev tsis muaj zog cov qe thiab cov larvae dhau mus, uas lawv dhau mus thaum cov xwm txheej tsis zoo kawg.
Ntawm qhov tod tes, nyob rau hauv cov teb chaws uas qhov kub thiab txias yuav luag txhua xyoo puag ncig thiab muaj cov dej tsis muaj tsawg, ib yam li cov xwm txheej nyob rau hauv cov teb chaws sov, ces yoov tshaj cum tuaj yeem tsim tau tas li, txij li cov xwm txheej ib puag ncig yog qhov zoo rau cov txheej txheem no. Yog li ntawd, nyob rau hauv cov cheeb tsam sov, hom muaj ntau tiam neeg nyob rau tib lub xyoo feem ntau pom.
yoov tshaj cum nyob ntev npaum li cas?
yoov tshaj cum, raws li peb tau pom, mus rau theem sib txawv, txij li lub qe mus rau thaum lawv loj tuaj, tab sis yoov tshaj cum nyob tag nrho ntev npaum li cas? Cia peb paub tias txhua theem kav ntev npaum li cas:
- Qe: nruab nrab ntawm 2 thiab 4 hnub tom qab tso.
- Larva: kwv yees li 5 hnub.
- Pupa: nruab nrab ntawm 2 mus rau 5 hnub.
- Cov neeg laus: cov txiv neej tuag ob peb hnub tom qab yug me nyuam (kwv yees li 3 mus rau 5), thaum cov poj niam nyob ntev, vim lawv yuav tsum tau noj kom txaus rau kev loj hlob ntawm cov qe thiab nteg lawv, thiaj li nyob tau mus txog. ob lis piam.
Lub neej ntawm yoov tshaj cum nyob ntawm ntau yam ib puag ncig, uas yog qhov tseem ceeb rau lawv. Nyob rau hauv qhov kev nkag siab no, qhov kub thiab txias, av noo, zaub mov thiab ob qho tib si muaj thiab tej yam kev mob ntawm nruab nrab nteg qe, txiav txim lub neej thiab kev loj hlob ntawm yoov tshaj cum.
txiv neej yoov tshaj cum nyob nruab nrab ntawm 10 mus rau 15 hnub, thaum females tuaj yeem nyob tau mus txog 24 hnub Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov kab no yog kwv yees thiab dav, vim tias muaj ntau qhov sib txawv ntawm qee hom.
