Yuav ua li cas tiv thaiv hazelnut borers organically?
Hazelnut borer yog kab tsuag uas tawm tsam lub plhaub ntawm hazelnuts. Rau kev tswj kev lom neeg, tsob ntoo co, xaiv qoob loo, txiv qaub rings, nematodes, nrog rau qaib thiab ducks noj hazelnut borers thiab larvae yog tsim nyog. Thaum ntxov ripening hazelnut ntau yam yog resistant rau kab tsuag.
- Hazelnut borer yog 6-9 hli loj, dub-xim av-dawb weevil uas nws kev loj hlob thiab pub mis yog txaus ntshai rau hazelnuts nrog rau lub buds, paj thiab txiv hmab txiv ntoo ntawm lwm yam txiv hmab txiv ntoo ntoo.
- Poj niam xyaum lub qhov hauv lub plhaub los nteg qe. Qe thiab larva txoj kev loj hlob tshwm sim nyob rau hauv lub hazelnut txij lub Rau Hli mus txog rau.
- Cov tshuaj tiv thaiv kab mob muaj txiaj ntsig zoo yog: chais tawm, xaiv qoob loo, nplaum rings, nematodes nrog rau pecking qaib thiab ducks.
Dab tsi yog hazelnut borer?
Hazelnut borer yog kab nrog ntev heev proboscis
Hazelnut borer yog kab los ntawm tsev neeg loj ntawm weevils. Mated poj niam nteg lawv cov qe nyob rau hauv unripe hazelnuts kom voracious maggots muaj peev xwm tsim undisturbed nyob rau hauv kev tiv thaiv ntawm lub plhaub. Tom qab ib hlis, ib tug neeg laus larva tawm ntawm qhov chaw khoob, tawm hauv ib lub qhov txawv ntawm lub plhaub. Kev sib xyaw ua ke ntawm kev tsim tawm tsis zoo thiab kev noj zaub mov tsis zoo tau ua rau hazelnut borer nws lub koob npe nrov li kab tsuag. Cov ntaub ntawv hauv qab no muab cov ntaub ntawv sib cog lus txog kab thiab kab laug sab:
| Profile | Hazelnut xyaum | Larva |
|---|---|---|
| Size | 6-8, 5mm | 12-15mm |

Liab-xim av antennae thiab ob txhais ceg ua tiav cov tsos. Nws pom tseeb tias hazelnut borer muaj lub cev ntev ntawm cov poj niam thiab luv luv rau cov txiv neej.
Cov larva, uas ntev txog li 1.5 centimeters, muaj cov xim creamy dawb maggot zoo li. Lub qhov ncauj muaj zog nrog cov hniav ntse zaum ntawm lub taub hau xim av. Qhov no tso cai rau cov worms tom los ntawm cov txiv ntoo tawv tawv ntawm lawv txoj kev ywj pheej.
Txoj kev ua neej ntawm kab thiab larvae
Lub larvae ntawm hazelnut borer pub rau unripe hazelnuts
Cov lus qhia nram qab no los ntawm lub xyoo hazelnut borer qhia tias vim li cas cov kab no raug cais ua kab tsuag:
- Pib kev ua si: txij lub Peb Hlis/Lub Plaub Hlis, cov kab laus laus tawm lawv lub caij ntuj no hauv av
- Khoom noj khoom haus: Ripening puas rau buds, paj thiab nplooj ntawm cherries, pears, txiv apples, txiv duaj thiab lwm yam txiv hmab txiv ntoo ntoo
- Reproduction: txij lub Rau Hli mus txog rau lub Rau Hli, cov poj niam txiv neej tuaj txog rau cov txiv hmab txiv ntoo siav nrog lub plhaub mos thiab 8-12 hli inch
- Egg laying: Poj niam xyaum qhov hauv lub plhaub los tso qe
- Qe hatching: in a week
- Khoom noj khoom haus: Larva pub rau ntawm lub plab hauv qab lub plhaub rau peb mus rau plaub lub lis piam
Tus neeg laus larva nthuav lub qhov uas twb muaj lawm hauv lub plhaub thiab nyem nws tus kheej los ntawm. Raws li txoj cai, tus kab mob hazelnut twb poob los ntawm tsob ntoo. Qhov no txhais tau hais tias cov maggot tau yooj yim tawm ntawm nws qhov chaw zov me nyuam thiab burrows 10 centimeters tob rau hauv av, qhov chaw nws pupates thiab hibernates.

Thov pov tseg cov qoob loo hauv tsev pov tseg thiab tsis nyob hauv cov chiv. Ua raws li tus qauv no kom txog thaum lub sijhawm sau qoob. Tshwj xeeb tshaj yog, cov txiv ntseej nrog cov lus piav qhia drilled qhov hauv lub plhaub tsis haum rau kev noj thiab muab pov tseg.
Tip
Nrog lub vaj ze ze rau qhov xwm txheej, hazelnut gardeners sib tw kom tsis txhob mus ntsib cov yeeb ncuab ntawm hazelnut borer. Thaum tsis muaj tshuaj tua kab hloov hauv av mus rau hauv qhov chaw muaj tshuaj lom, pawg nplooj thiab ntoo tuag tseem nyob ib puag ncig, thiab cov txiv hmab txiv ntoo qus tuaj yeem caw koj mus pw, tus hedgehog zoo siab tos txais. Yog hais tias tus dais ntxim hlub prickly pom ib lub tsev zoo nkauj hedgehog, nws yuav zoo siab nyob thiab mus yos hav zoov rau hazelnut borers thiab voracious larvae nrog rau ntau yam kab tsuag.
Kev sib ntaus hazelnut borers biologically
Cov tshuaj tiv thaiv kab mob lom tau pom zoo hauv cov lus saum toj no muaj kev cuam tshuam ob npaug rau hazelnut borers. Glue rings aim poj niam beetles thaum lawv mus txog. Nematodes parasitize burrowed larvae hauv lawv lub caij ntuj no. Yuav ua li cas tiv thaiv hazelnut borers nyob rau hauv kev sib raug zoo nrog xwm:
Cov kua nplaum nplaum
Cov nplaum nplaum yog cov tshuaj tua kab uas tsis muaj tshuaj lom rau ntawm tsob ntoo. Ib daim kab xev coated nrog kua nplaum yog muab tso rau ib ncig ntawm lub cev. Yog hais tias hazelnut borers nkag rau ntawm cov tawv ntoo ntawm lub crown, lawv lo rau lub nplhaib nplaum thiab tuag. Tsis tsuas yog cov ntoo hazelnut nrog cov nplaum nplaum tiv thaiv kab tsuag, tab sis tag nrho cov ntoo txiv ntoo. Qhov no yog li cas cov nplaum nplaum ua tiav qhov zoo tshaj plaws tswj kev ua tau zoo tiv thaiv cov npauj te, codling npauj thiab lwm yam rabble.
Koj tuaj yeem paub yuav ua li cas txuas lub nplhaib nplaum kom raug hauv cov yeeb yaj kiab hauv qab no:

Nematodes
Nematodes yog microscopic roundworms uas nteg lawv qe nyob rau hauv larvae. Cov txheej txheem no tsis xaus zoo rau larva. Feem ntau cov nematodes ntawm genus Heterorhabditis bacteriophoba (HM nematodes) txiav txim siab cov neeg hazelnut borer hauv koj lub vaj los txog li 50 feem pua. Koj tuaj yeem yuav cov kab muaj txiaj ntsig los ntawm cov khw muag khoom tshwj xeeb. Cov kab mob me me raug xa mus rau hauv av nplaum granules (€ 18.00 ntawm Amazon), uas koj yaj hauv dej thiab siv nrog lub pas dej da dej. Lub sijhawm zoo tshaj plaws rau kev sib ntaus sib tua yog los ntawm Lub Yim Hli, thaum cov rog maggots nkaum hauv av kom dhau lub caij ntuj no.
Feathered yeeb ncuab rhuav tshem hazelnut borers
qaib nyiam noj hazelnut borers thiab lwm yam kab tsuag
Hobby gardeners uas khaws qaib muaj qhov kom zoo dua hauv kev tswj kom ruaj khov ntawm hazelnut borers. Pecking chickens yog cov yeeb ncuab tshaj tawm ntawm kab thiab larvae. Yog tias koj teeb tsa ib qho chaw sab nraum zoov ib ntus ib ncig ntawm cov ntoo hazelnut txij lub Peb Hlis mus txog rau lub Tsib Hlis, tsis muaj kab tsuag yuav dim ntawm cov nqaij qaib tsis khoom.
Cov feathered yeeb ncuab ntawm hazelnut borers thiab larvae muaj xws li khiav ducks. Cov ducks uas ntxim hlub, tsis muaj ya raws feem ntau yog ntiav los tua cov qwj hauv lub vaj. Penguin ducks kuj muaj kab ntawm txhua yam thiab lawv cov larvae ntawm lawv cov zaub mov.

Dab tsi ua rau hazelnut borer puas?
Lub Rau Hli, cov poj niam xyaum lub qhov me me hauv lub plhaub tseem mos ntawm cov tub ntxhais hluas hazelnuts thiab nteg ib lub qe. Tom qab plaub mus rau tsib lub lis piam ntawm kev loj hlob hauv cov txiv ntoo, ib tug larva noj nws txoj kev los ntawm lub plhaub. Tus thawj, NW nyuam qhuav pom puag ncig qhib yog loj mus rau ib txoj kab uas hla mus txog 2 millimeters. Qhov kev puas tsuaj uas tsis tuaj yeem tshwm sim los ntawm tus kab mob hazelnut yog qhov drilling thiab tshem tawm qhov.
Puas hazelnut borers ya?
Yog lawm, cov neeg laus hazelnut borers tuaj yeem ya. Zoo li feem ntau weevils, hazelnut borers kuj tau nruab nrog lub tshuab ua haujlwm ya. Txawm li cas los xij, beetles nyiam taug kev ncig ko taw hauv kev tshawb nrhiav cov ntoo hazelnut thiab lwm yam ntoo txiv ntoo.
Koj tuaj yeem tiv thaiv hazelnut borer kab mob li cas?
Kev tillage tsis tu ncua nyob rau hauv thaj tsam ntawm tsob ntoo crown los ntawm lub caij nplooj ntoos hlav thaum ntxov ua rau overwintering larvae ua ntej lawv ya tawm raws li cov kab tiav. Rake cov av ntawm lub hauv paus disc vigorously. Qhov zoo tshaj plaws, koj yuav tsum tau npog tsob ntoo nrog cov nroj tsuag los yog lub vaj fleece uas catches hatched beetles. Ua ntej, peb pom zoo kom fertilizing nrog txiv qaub nitrogen, uas muaj pov thawj zoo nyob rau hauv kev tswj lom ntawm txhua yam larvae.
Qhov twg koj tuaj yeem yuav nematodes tiv thaiv hazelnut borers?
Muaj ntau qhov chaw yuav khoom hauv cov khw muag khoom tshwj xeeb thiab hauv online, xws li cov khw muag khoom kho vajtse lossis chaw ua vaj tsev. Tsis yog txhua tus ntawm lawv coj mus rau hauv tus account qhov tseeb tias lawv yog cov kab uas muaj txiaj ntsig zoo. Yog li ntawd, peb pom zoo kom yuav nematodes ncaj qha los ntawm kev ua liaj ua teb muaj peev xwm. Tsiaj-phooj ywg xa khoom ntawm cov khoom muaj nqis yog lav ntawm no.
Tip
Tub tob hauv av, hazelnut borer larvae tsis tuaj yeem muaj kev nyab xeeb thaum Mr. Mole nyob ntawd. Dab tsi qaib beaks thiab nematodes tsis ntes yog txoj cai rau cov kab hauv av. Fat larvae tsis nyob twj ywm zais ntawm lub qhov ntswg rhiab mole ntev nyob rau hauv lawv lub caij ntuj no quarters. Vim li no, natural gardeners tsis prey ntawm pab kab noj thiab generously zam lub sij hawm molehill nyob rau hauv lub txaj.
