Entomopathogenic nematodes tau nrawm nrawm los ntawm kev muaj koob npe raws li kev pov thawj ntawm kev tshem tawm cov kab tsuag. Dab tsi yog cov txiaj ntsig nematodes ho? Mus nyeem ntawv kom paub ntau ntxiv txog kev siv nematodes li tshuaj tua kab.

Dab tsi yog cov txiaj ntsig nematodes?

Cov tswv cuab ntawm Steinernematidae thiab Heterorhabditidae tsev neeg, cov nematodes zoo rau kev ua teb, yog cov kab mob tsis muaj xim uas tsis yog-segmented, elongated hauv cov duab, thiab feem ntau microscopic thiab feem ntau pom nyob hauv av.

Entomopathogenic nematodes, los yog cov nematodes zoo, tuaj yeem siv los tswj cov av uas muaj kab tsuag kab tsuag tab sis tsis muaj txiaj ntsig rau kev tswj cov kab tsuag uas muaj nyob hauv nplooj nplooj. Cov txiaj ntsig zoo rau kev tiv thaiv kab tsuag tuaj yeem siv los tua kab tsuag xws li:

• Grubs
• Crane yoov
• fungus gnats

Tseem muaj cov nematodes phem thiab qhov sib txawv ntawm cov nematodes zoo thiab cov phem yog qhov yooj yim uas tus tswv lawv tawm tsam; nematodes phem, tseem hu ua tsis muaj txiaj ntsig, hauv paus pob txha, lossis "cov kab mob cab" nematodes, ua rau cov qoob loo puas tsuaj lossis lwm yam nroj tsuag.

Yuav Ua Li Cas Nematodes ZooUa haujlwm?

Nyob zoo nematodes raws li kev tswj kab tsuag yuav tua cov av uas muaj kab tsuag uas tsis muaj kev phom sij rau cov tsiaj txhu, nroj tsuag, tsiaj txhu, lossis tib neeg, ua rau nws muaj kev tiv thaiv ib puag ncig. Lawv yog cov morphologically, ecologically, thiab noob caj noob ces ntau ntau dua li lwm pawg tsiaj, tshwj tsis yog arthropods.

Nrog ntau dua 30 hom kab mob entomopahogenic nematodes, txhua tus muaj tus tswv tsev tshwj xeeb, nrhiav cov nematode tsim nyog los pab tswj kab tsuag tsis yog tsuas yog "ntsuab" kev daws teeb meem ntawm kev tswj xyuas kab tsuag, tab sis ib qho yooj yim thiab.

Nyob zoo nematodes muaj lub neej voj voog uas muaj qe, plaub theem larval, thiab ib theem neeg laus. Nws yog thaum lub sij hawm thib peb larval theem uas cov nematodes nrhiav ib tug tswv tsev, feem ntau yog kab larvae, thiab nkag mus rau nws los ntawm tus tswv lub qhov ncauj, qhov quav, los yog spiracles. Cov nematode nqa cov kab mob hu ua Xenorhabdus sp., uas yog tom qab nkag mus rau hauv tus tswv tsev thaum tus tswv tsev tuag nyob hauv 24 mus rau 48 teev.

Cov Steinernematids loj hlob mus rau cov neeg laus thiab tom qab ntawd ua phooj ywg hauv tus tswv tsev lub cev, thaum Heterorhabditids tsim cov poj niam hermaphroditic. Ob hom nematode ingesting tus tswv tsev cov ntaub so ntswg kom txog thaum lawv loj hlob mus rau lub thib peb juvenile theem thiab ces lawv tawm cov seem ntawm tus tswv tsev.

Nematodes as Pest Control

Siv cov txiaj ntsig nematodes rau kev ua vaj tshuaj tua kab tau dhau los ua txoj kev nrov zuj zus rau rau qhov laj thawj:

• Raws li tau hais dhau los, lawv muaj ntau tus tswv tsev zoo kawg thiab muaj peev xwm, yog li, siv los tswj cov kab ntau kab.
• YEntomopathogenicnematodes tua tus tswv sai sai, hauv 48 teev.
• Nematodes tuaj yeem loj hlob ntawm cov khoom siv dag zog, ua kom yooj yim thiab pheej yig khoom.
• Thaum cov nematodes khaws cia ntawm qhov kub zoo, 60 txog 80 degrees F. (15-27 C.), lawv yuav nyob twj ywm rau peb lub hlis thiab yog tias tso rau hauv tub yees ntawm 37 txog 50 degrees F. (16-27 C.), tej zaum yuav kav rau lub hlis.
• Lawv ua siab ntev rau cov tshuaj tua kab, tshuaj tua kab, thiab tshuaj chiv, thiab cov menyuam yaus muaj peev xwm muaj sia nyob tau ib lub sijhawm yam tsis muaj zaub mov noj thaum tab tom nrhiav tus tswv tsev tsim nyog. Nyob rau hauv qhov tseeb, lawv yog resilient thiab check.
• Tsis muaj kab tiv thaiv kab mob rau cov kab mob Xenorhabdus, txawm hais tias cov kab muaj txiaj ntsig feem ntau khiav tawm ntawm kab mob vim tias lawv muaj zog dua thiab txav mus deb ntawm nematode. Cov nematodes tsis tuaj yeem txhim kho hauv cov kab mob vertebrates, uas ua rau lawv muaj kev nyab xeeb thiab zoo ib puag ncig.

Yuav Ua Li Cas Thov Entomopathogenic Nematodes

Nyob zoo nematodes rau kev ua teb tuaj yeem pom muaj nyob rau hauv cov tshuaj tsuag lossis cov dej hauv av. Nws yog ib qho tseem ceeb uas yuav tau siv lawv ntawm ib puag ncig zoo tshaj plaws uas xav tau rau lawv txoj sia nyob: sov thiab noo.

Irrigate site application ob leeg ua ntej thiab tom qab qhia cov nematodes thiab tsuas yog siv thaum av kub ntawm 55 thiab 90 degrees F. (13-32 C.) hauv lim hnub.

Siv cov khoom nematode nyob rau hauv lub xyoo thiab tsis txhob khaws cia rau hauv qhov chaw uas muaj cua sov. Nco ntsoov, cov no yog cov tsiaj muaj sia.
