Grubs - lawv zoo li rog, kab kab dawb - nyob hauv yuav luag txhua lub vaj. Cov no yog cov larvae ntawm ntau hom kab beetles, qee qhov teeb meem thiab lwm yam tseem ceeb heev. Hauv tsab xov xwm no koj yuav pom tias yuav ua li cas thiaj paub qhov txawv ntawm cov kab tsuag thiab cov kab muaj txiaj ntsig thiab yuav ua li cas los tawm tsam cov qub tau zoo.
Grub yog dab tsi?
Grubs yog larvae ntawm ntau hom kab. Qee cov grubs yog siv los tsim humus. Lwm tus yog kab tsuag. Lawv cov khoom noj yog decomposed cov khoom cog thiab cov hauv paus hniav. Grubs tuaj yeem ua rau muaj kev puas tsuaj loj heev, tshwj xeeb tshaj yog rau cov nroj tsuag hluas. Lawv tuaj yeem paub qhov txawv ntawm qhov txawv.
- Lub larvae ntawm ntau hom kab kab kab hu ua grubs.
- Feem ntau grubs nyob hauv av tau ntau xyoo, tab sis kuj pom muaj nyob rau hauv txaj, paj lauj kaub los yog compost.
- Tsis yog tag nrho cov grubs yog kab tsuag, qee qhov - xws li cov kab mob ntawm cov kab roses lossis rhinoceros beetle - tseem muaj txiaj ntsig zoo rau kev tsim cov humus thiab yog li zoo siab txais tos cov qhua hauv cov khib nyiab pov tseg.
- Cov kab mob phem tuaj yeem tswj tau siv ntau txoj kev tsis muaj tshuaj lom, tab sis lawv feem ntau tsuas yog teeb meem thaum lawv tshwm sim ntau.
Grub yog dab tsi?
Grubs kuj loj, feem ntau ci larvae
Grubs yog cov larvae ntawm ntau hom kab kab los ntawm tsev neeg scarab kab (Latin: Scarabaeidae). Lub npe los ntawm Cov Laus lossis Nruab Nrab Siab German thiab hais txog qhov tshwm sim ntawm cov larvae: Nws txhais tau tias ib yam dab tsi zoo li "maggot" lossis "mob worm".
Scarf beetles yog ib tsev neeg loj heev uas suav nrog ntau dua 27,000 hom tsiaj thoob ntiaj teb. Tsuas yog qee qhov ntawm cov no tshwm sim hauv peb lub vaj, thiab ntau tus raug hem nrog kev ploj tuag lossis tau dhau los ua tsawg heev. Qhov no siv, piv txwv li, rau cockchafer, uas nws cov grubs tuaj yeem ua rau muaj kev puas tsuaj loj thiab ua rau muaj kev tshaib kev nqhis nyob rau ntau pua xyoo dhau los. Hauv xyoo 1950 thiab 1960s cov tsiaj txhu tau sib ntaus sib tua, yog li ntawd lawv tsis tuaj yeem pom niaj hnub no. Hauv qee lub xyoo lawv tseem tshwm sim loj heev thiab tuaj yeem ua rau muaj kev puas tsuaj loj hauv cheeb tsam.
Txawm li cas los xij, tsis yog txhua tus kab npauj npaim thiab lawv cov kab sib txuas tuaj yeem raug cais ua kab tsuag. Qhov tsis sib xws, vim tias cov kab mob ntawm cov kab rose thiab cov kab rhinoceros tsawg heev (uas yog ib hom kev tiv thaiv) yog suav tias yog cov kab uas muaj txiaj ntsig zoo heev.
Hauv lub vaj thiab ntawm lub sam thiaj koj yuav pom cov hom no:

Lawv nyob hauv av li ntawm peb mus rau tsib xyoos ua ntej lawv pupate thiab loj hlob mus rau hauv tag nrho-fledged beetles.
Yuav siv sijhawm ntev npaum li cas los txhim kho los ntawm tus kws sau ntawv mus rau ib tug cockchafer?
Tej kab thiab lwm yam kab yog grub rau feem ntau ntawm lawv lub neej
Cockchafers thiab lwm yam kab cab siv lub sijhawm ntev tshaj plaws ntawm lawv lub neej raws li grubs - lawv txoj kev loj hlob ntawm cov menyuam yaus mus rau theem kab loj hlob yuav siv sijhawm li peb mus rau tsib xyoos. Cov kab laus - hu ua imago - tsuas yog tso cai rau lub neej luv luv: tus txiv neej tuag tom qab lub davhlau nuptial, tus poj niam tom qab tso nws lub qe. Tus neeg laus theem feem ntau kav li plaub mus rau xya lub lis piam.
Grubs nyob hauv av ntev npaum li cas?
Grubs nyob hauv av rau ntawm peb mus rau tsib xyoos. Lawv txoj kev loj hlob sai yog nyob ntawm thaj av thiab kev nyab xeeb nyob rau ntawd: Hauv thaj chaw sov, kev loj hlob ntawm larvae mus rau kab yog sai dua nyob rau hauv cov huab cua txias. Txawm li cas los xij, tsis yog txhua tus grubs ncav cuag cov neeg laus: feem ntau yog noj los ntawm cov tsiaj nyeg, succumb mus rau kab mob (piv txwv li los ntawm fungi), raug tua los ntawm gardeners los yog tsuas tsis ciaj sia lub caij ntuj no.
Nkauj hmoob nyob hauv av sib sib zog nqus li cas?
Lub Tsib Hlis thiab Lub Rau Hli kab kab larvae pom nyob ze ntawm qhov chaw; tom qab tag nrho, lawv tsuas yog noj cov hauv paus hniav. Feem ntau koj tuaj yeem pom lawv ntawm qhov tob ntawm tsib mus rau 25 centimeters. Tsuas yog thaum lawv pupate ua cov grubs tsiv mus tob: tam sim no cov pupae tuaj yeem pom txog li 60 centimeters tob. Lawv nyob ntawm no ib txog ob xyoos.
Koj tuaj yeem noj grubs?
Nyob hauv lub tebchaws no - sib piv rau lwm thaj chaw hauv ntiaj teb - nws tsis yog ib txwm noj beetle larvae thiab feem ntau cov neeg feem ntau xav tsis thoob los ntawm lub tswv yim. Qhov tseeb, grubs yog edible, txawm tias peb tsis pom zoo rau lawv noj. Nyob ntawm seb cov grub tau noj dab tsi, nws tuaj yeem ua rau muaj tshuaj lom heev thiab yog li tsim kev puas tsuaj rau kev noj qab haus huv. Cov co toxins ntawm ntau cov nroj tsuag tsis ua mob rau cov larvae, tab sis lawv nqus tau rau hauv lawv lub cev thiab kis mus rau lawv cov tsiaj nyeg.
Tip
Yog hais tias grubs tshwm nyob rau hauv lub compost, lawv feem ntau yog rose beetle larvae. Lawv pab ua lub vaj pov tseg rau hauv compost thiab yog li ntawd tseem ceeb heev. Khawb lawv rov qab sai sai vim tsiaj tsis tuaj yeem tiv tshav ntuj thiab yuav tuag sai sai.
