Cov kab yoov tshaj cum tom qab yoov tshaj cum yog qhov ntxim nyiam thiab kab me me heev. Nws cov kab menyuam voracious ntau raug mob cruciferous cov qoob loo - nplooj tawm tsam los ntawm lawv dhau los ua corrugated thiab sai shrivel, thiab cov nplooj petioles pom tau khoov thiab tuab nyob ze ntawm lub hauv paus. Lub apical buds ntawm cov nroj tsuag feem ntau tuag tawm, thiab hloov lawv los ntawm cov axillary buds, qee zaum ob peb qhov me me "coots" tau tsim. Yog tias, ntxiv rau txhua yam, huab cua sov thiab noo tau teeb tsa, tom qab ntawd "lub siab" ntawm zaub qhwv yuav pib rot. Petiole yoov tshaj cum yog tshwj xeeb tshaj yog txaus ntshai rau cov zaub qhwv

Ntsib kab tsuag

Cov kab yoov tshaj cum tom qab yoov tshaj cum yog kab me heev - nws loj li ntawm 1.5 txog 2 hli. Lub cev ntawm cov kab no yog cov xim daj nrog xim ntsuab me ntsis, thiab cov kab txaij hla ntawm lub plab thiab lub hauv siab ntawm lub mis yog xim av. Antennae hauv poj niam nce mus txog ib nrab ntawm qhov ntev ntawm lub cev, thiab cov kav hlau txais xov ntawm cov txiv neej pom ntau tshaj qhov ntev ntawm lawv lub cev.

Cov pob tshab thiab khoov me ntsis ntawm cov kab me me no muaj txog 0.25 hli ntev thiab txog 0.08 hli dav. Cov kab daj daj, uas loj hlob mus txog 2 hli ntev, tau txais txiaj ntsig nrog ob peb lub kav hlau txais xov me me. Lawv thawj lub thoracic ntu yog qhov nqaim heev (thiab qee zaum txawm tias thim rov qab sab hauv), thiab nyob rau sab qis ntawm ob lub mis muaj cov phaj me me (hauv lwm lo lus, "spatula"), nruab nrog qhov tob tob hauv qhov dav. Los ntawm txoj kev, txhua tus larvae muaj peev xwm thaws.

Pupae ntawm yoov tshaj cum me me muaj tus txha nqaj me me nyob tom qab ntawm lawv lub cev. Thiab kev tsim ntawm pupae tshwm sim hauv qhov sib npaug cocoons, mus txog 2 hli txoj kab uas hla thiab densely them nrog me me ntawm cov av.

Kab tsuag feem ntau nyob rau hauv av nyob rau theem ntawm tus menyuam. Nrog rau qhov pib ntawm lub caij nplooj ntoo hlav, yoov tshaj cum me me ya tawm ntawm cov txiv hmab txiv ntoo thiab pib nteg qe yuav luag tam sim - lawv nteg lawv, raws li txoj cai, hauv pawg, qhov nruab nrab ntawm kaum tsib rau nees nkaum daim txhua. Thiab qe tau muab tso rau feem ntau hauv "lub siab" (apical buds) ntawm ntau yam qoob loo cruciferous - rapeseed, zaub qhwv, thiab lwm yam.

Tom qab li plaub txog tsib hnub, thaum tus pas ntsuas kub nce mus txog nees nkaum degrees, voracious larvae pib tshwm los ntawm lub qe. Lawv mloog zoo nyob rau hauv cov quav ntawm cov tub ntxhais hluas nplooj thiab ze rau lub hauv paus ntawm lawv cov petioles. Tom qab ib ntus, tag nrho cov larvae pupate hauv av. Dua li qhov tseeb tias nws tsis muaj peev xwm tsim kom muaj pes tsawg tiam neeg ntawm cov zaub qhwv petiolate yoov tshaj cum, nws ntseeg tias kab tsuag no muab tsawg kawg plaub tiam rau txhua lub caij.

Koj tuaj yeem ntsib cov cab no hauv vaj tsis yog tsuas yog ntawm cov zaub qhwv apical buds - lawv tuaj yeem pom feem ntau hauv cov paj ntoo tawg ntawm txhua yam ntawm cov qoob loo cruciferous.

Yuav ua li cas sib ntaus

Thaum cog cov yub, txhua cov nroj tsuag nrog lub paj tawg apical yuav tsum tau ua tib zoo pov tseg. Yog tias nws tau pom tam sim ntawd tias lub taub hau ntawm zaub qhwv, tsis yog pib tsim los ntawm cov hauv paus hauv paus tuag, pib txhim kho los ntawm ob sab paj, nws yog qhov tsim nyog los tsim cov xwm txheej tsim nyog rau lawv los txhawb kev txhim kho kev loj hlob - raws li txoj cai, siab- dej zoo thiab pub mis tau siv rau lub hom phiaj no.

Ib qho ntawm qhov ntsuas tseem ceeb tshaj plaws los tiv thaiv yoov tshaj cum yog lub sij hawm pov tseg ntawm cov nroj - cov kab tsuag zoo li no feem ntau tshwm sim ntawm cov ntoo cruciferous. Thiab nrog qhov pib ntawm lub caij nplooj zeeg, nws yog qhov yuav tsum tau khawb cov av.

Hauv cov xwm txheej tshwj xeeb ntawm cov kab me me no, lawv hloov mus rau kev kho tshuaj tua kab. Xws li txhais tau tias "Belofos", "Sumicidin", "Tsimbush", "Anometrin", "Talkord" thiab "Rovikurt" pab tiv thaiv lawv tau zoo. Thiab thaum tsis muaj cov ntawd, koj tuaj yeem siv "Etaphos", "Cyanox" lossis "Foxim".
