Apion, lossis clover weevil, muaj nyob hauv yuav luag txhua qhov latitudes. Nws cov zaub mov nyiam suav nrog clover, ob qho tsiaj qus thiab cog qoob loo. Cov kab menyuam ntawm cov cab no, uas zawm qhov hauv qhov chaw rau cov menyuam tom ntej, yog qhov tshwj xeeb tshaj yog muaj kev phom sij, vim tias cov hlab ntsha pub mis rau paj tau puas. Thiab qhov no, nyeg, ua rau ua kom tiav lossis ib nrab xim av ntawm cov paj thiab kom lawv qhuav tom ntej. Cov neeg laus yoov kuj tseem muaj teeb meem heev, pub mis rau ntawm cov nplooj clover thiab zom ntau qhov hauv lawv. Hauv lub xyoo ntawm kev rov tsim dua tshiab, nplooj apions feem ntau raug khawb nrog qhov
Ntsib kab tsuag
Apiona yog cov kab dub dub uas tsis zoo, qhov loj ntawm thaj tsam li 3 txog 3.5 hli. Nws lub cev-pear-puab lub cev yog tus yam ntxwv ua kom pom xim hlau. Txhua tus neeg tau txais txiaj ntsig nrog yuav luag ncaj rostrum thiab ib nrab ceg daj. Cov kab no muaj cov kav hlau txais xov zoo heev - lawv cov hauv paus feem ntau yog xim liab, thiab sab saum toj yog xim dub.
Apion qe ntau qhov loj los ntawm 0.3 txog 0.5 hli. Cov qe tso los ntawm cov cab no feem ntau yog du, elongated thiab xim daj. Thiab lub larvae ntawm kab yog dawb nrog me ntsis creamy tint. Hauv qhov ntev, lawv loj tuaj txog 2 - 2, 5 mm. Txhua tus kab laug sab muaj lub taub hau tsaus xim av thiab nkhaus me ntsis. Lawv lub puab tsaig sab sauv tau nruab nrog peb qhov kev nthuav dav ntawm txhua sab, nrog rau qhov nruab nrab qhov nruab nrab feem ntau nthuav dav me ntsis. Thiab ob txhais ceg ntawm cov kab menyuam tau hloov pauv los ntawm ntau li rau rau khub ntawm cov pob zeb me me txawv txawv. Raws li rau pupae ntawm kab tsuag, lawv tau pom los ntawm xim daj -dawb thiab mus txog qhov ntev ntawm 3 - 3.5 mm.
Beetles overwinter ntawm cov qoob loo clover, ntawm qhov tob txog li tsib centimeters hauv av. Ib feem ntawm kab tsuag hibernates ntawm cov ciam teb, ntawm ntug hav zoov, ntawm ntug kev, hauv hav thiab hauv hav zoov txoj siv sia. Raws li txoj cai, hauv cov chaw tiv thaiv no, lawv tau xa mus rau hauv qhov seem ntawm cov nroj tsuag thiab hauv qab nplooj poob. Kev tawm ntawm cov kab mob gluttonous los ntawm cov chaw nyob rau lub caij ntuj no feem ntau pib nyob rau thawj xyoo thiab zaum ob ntawm lub Plaub Hlis, thaum clover pib loj hlob. Rau kaum tsib mus rau nees nkaum ib hnub, lawv noj ntawm parenchyma ntawm cov nplooj ntoo hluas, thaum qoj ntau qhov me me. Thiab nyob rau theem ntawm clover budding (kwv yees li nyob rau ib nrab ntawm lub Tsib Hlis), poj niam pib nteg qe ib leeg, tso lawv rau hauv lub taub hau rudimentary, ntxiv rau hauv paj thiab sab nplooj nplooj.
Qhov nruab nrab fertility ntawm txhua tus poj niam yog kwv yees li peb caug-tsib lub qe, thaum qhov tsawg kawg pib yog 11 lub qe, thiab qhov siab tshaj plaws yog 217. Txhawm rau tso qe, poj niam yuav tsum tau zawm qhov nrog kev pab ntawm rostrum thiab thawb lub qe rau hauv lawv nrog tus ovipositor. Kev loj hlob ntawm embryonic ntawm lub qe yuav siv sijhawm tsib mus rau yim hnub. Thawj cov menyuam yaus hatch txawm tias ua ntej pib pib tawg paj (kwv yees thaum kawg ntawm lub Tsib Hlis thiab thaum pib Lub Rau Hli), thiab thaum lub sijhawm tawg paj loj, nyob qhov twg hauv ob xyoo kaum ob ntawm Lub Rau Hli, nws twb tuaj yeem pom tsis yog cov kab sib txawv hnub nyoog, tab sis kuj me me pupae.
Hauv cov xwm txheej ntawm hav zoov-steppe, kev txhim kho ntawm voracious larvae yuav siv sijhawm kaum tsib mus rau nees nkaum hnub. Tam sim ntawd ua ntej kev yug menyuam, lawv tawm ntawm lub zes qe menyuam thiab mus rau lub qhov taub ntawm lub taub hau clover, tsom mus rau qhov sib nrug nruab nrab ntawm cov paj. Ntawm no lawv gnaw qhov thiab pupate hauv lawv. Pupal txoj kev loj hlob yuav siv sijhawm li yim mus rau cuaj hnub. Thiab tag nrho kev txhim kho mus los, los ntawm theem qe mus rau theem neeg laus, siv sijhawm peb caug mus rau peb caug-ob hnub. Los ntawm qhov thib ib nrab ntawm Lub Xya Hli mus txog rau Lub Cuaj Hli (thiab qee zaum txog rau Lub Kaum Hli), koj tuaj yeem pom qhov pom ntawm cov kab, nquag pub mis rau ntawm cov tub ntxhais hluas clover nplooj.
Hauv ib lub caij, tsuas yog ib tiam ntawm clover weevils tsim, tab sis txhua tus kab tuaj yeem muaj sia nyob thiab rov tsim dua tshiab rau ob txog peb xyoos.
Yuav ua li cas sib ntaus
Qhov kev tiv thaiv tseem ceeb tiv thaiv apiona yog ua raws cov cai ntawm kev cog qoob loo. Nws raug nquahu kom tso cov noob qes clover ntawm qhov deb ntawm tsawg kawg ib nrab mais ntawm cov qoob loo.
Yog tias rau txhua kaum tus kab mob hauv net yuav muaj nees nkaum tus neeg ntawm cov kab, lawv npaj tshuaj tsuag tshuaj tua kab. Hauv theem pib, clover feem ntau kho nrog Fufanon thiab Diazinon.
