Steppe sowing nutcracker yog kab mob polyphagous. Koj tuaj yeem ntsib nws yuav luag txhua qhov, tshwj tsis yog cov av xuab zeb ntawm hav zoov. Hauv nruab nrab hav zoov-steppe thiab hauv txoj siv tawv chernozem, nws yog qhov txaus ntshai tshwj xeeb. Beetles feem ntau ua kev zoo siab rau cog ntawm succulent qab zib beet, thiab larvae txaus siab noj cov tub ntxhais hluas yub thiab cog noob tsis tsuas yog qab zib beet, tab sis kuj ntawm zaub thiab cereals. Thiab nyob rau lub caij nplooj zeeg, voracious larvae raug mob tsuas yog cov qos yaj ywm, thiab tseem tau koom nrog hauv kev cia siab, devouring pupae thiab larvae ntawm yoov thiab lwm tus kab

Ntsib kab tsuag

Cov steppe sowing nutcracker yog kab, qhov loj ntawm thaj tsam li ntawm 10 txog 15 hli. Qhov kab mob txaus ntshai no tau muab nrog lub cev dub dav nrog lub ntsej muag zoo nkauj tooj liab, thiab kab me me tuaj yeem pom ntawm nws sab nraub qaum. Lub taub hau convex ntawm kab yog coarsely thiab ntom ntom ntom. Poj niam feem ntau loj dua txiv neej, thiab lawv lub cev dav dua me ntsis, tab sis lub kav hlau txais xov yuav luv dua me ntsis.

Qhov ntev ntawm cov xim av daj-daj larvae nce mus txog 25 hli. Cov lus qhia tom qab ntawm cov kab menyuam yog me ntsis bifurcated, thiab txhua tus txheej txheem tau nruab nrog ib khub ntawm cov ntaub ntawv qhia ncaj qha mus rau nruab nrab. Qhov thais nruab nrab ntawm cov hniav feem ntau yog sib npaug.

Lub caij ntuj no ntawm cov kab tsis zoo tshwm sim nyob rau ntawm qhov tob ntawm kaum txog kaum ob centimeters hauv av, thiab voracious larvae ntawm cov hnub nyoog sib txawv feem ntau overwinter ntawm qhov tob ntawm tsib mus rau peb caug-tsib centimeters. Beetles tau xaiv rau ntawm cov av saum npoo av nyob qhov twg hauv ib nrab ntawm lub Plaub Hlis, nyob rau theem ntawm sowing qab zib beets thiab cov qoob loo thaum ntxov caij nplooj ntoo hlav. Cov hnub kwv yees kom pom cov neeg laus nyob hauv thaj chaw hav zoov-steppe yog lub sijhawm txij li 12 txog 25 Lub Plaub Hlis, thiab lawv cov xyoo loj, nrog rau kev sib yuav, tau ua kev zoo siab kwv yees li ntawm 27 Lub Plaub Hlis txog 12 Tsib Hlis. Nyob rau tib lub sijhawm, lub caij nplooj ntoo hlav tseem ceeb ntawm cov kab yog cov paj dandelion thiab lawv cov paj ntoos.

Cov steppe sowing clickers nteg qe hauv cov av hauv cov pawg me, txhua qhov uas muaj los ntawm peb txog tsib daim. Raws li txoj cai, ib lub clutch suav nrog los ntawm 12 txog 20 lub qe, thiab tag nrho kev yug menyuam ntawm poj niam yog los ntawm ob puas txog tsib puas qe. Cov qe ntawm cov kab no yog oval, me me thiab pleev xim rau xim dawb-qias neeg. Hauv av, lawv feem ntau nyuaj rau qhov txawv, vim lawv tau npog nrog cov av me me. Kev loj hlob ntawm embryonic ntawm voracious parasites yuav siv li peb lub lis piam. Thawj instar larvae, yug thaum lub Tsib Hlis lossis Lub Rau Hli, mus txog qhov ntev ntawm 2 hli. Lawv yuav luag pob tshab thiab tsis muaj xim. Lawv cov zaub mov yog cov me me invertebrates, nrog rau tua ntawm cov cog cog thiab nroj. Yeej, kev txhim kho cov kab menyuam yuav siv sijhawm 2-3 xyoos, tab sis qee zaum lub sijhawm no txuas ntxiv mus txog plaub xyoos. Thiab thaum lub Cuaj Hli-Lub Kaum Hli, cov kab menyuam, uas tau ua tiav lawv txoj kev txhim kho thiab tau noj txaus, khawb rau hauv av. Pupae, ntawm qhov tod tes, tsim rau tsuas yog peb txog plaub lub lis piam thiab muaj qhov zoo sib xws sab nraud rau cov neeg laus - cov txheej txheem txheej txheej sab nraub qaum rub rov qab tau pom meej ntawm lawv cov lus hais.

Yuav ua li cas sib ntaus

Ntawm cov kev tiv thaiv tiv thaiv cov steppe sowing nutcrackers, qhov tseem ceeb tshaj plaws kev ntsuas agrotechnical nyob hauv qhov chaw tseem ceeb: plowing caij nplooj zeeg, ua kom av zoo thiab tso cov av, nws liming, tshem cov nyom, ntxiv rau kev siv cov chiv (tshwj xeeb tshaj yog ammonia lossis potash)). Ib qho kev daws teeb meem zoo yuav yog qhia cov qoob loo rau hauv cov qoob loo uas tau tawg me ntsis los ntawm kab tsuag no. Ntawm cov qoob loo no yog mustard, flax thiab millet.

Thaum lub sijhawm tawg paj, nws raug nquahu kom qhia txog kev npaj ua los ntawm entomopathogenic nematodes rau hauv av. Nroj tsuag cov hauv paus hniav, qos tubers, cov khoom siv hauv av thiab av tau kho nrog neonicotinoids, organophosphorus sib txuas thiab cov pov thawj pov thawj zoo.

Ntawm cov yeeb ncuab ntuj ntawm cov menyuam ntxaib ntawm steppe sowing nutcrackers, ib tus tuaj yeem ceeb toom cov kab me me hauv av los ntawm Broscus tsev neeg. Txawm li cas los xij, cov neeg tua tsiaj no tsis ua lub luag haujlwm tseem ceeb hauv kev txo lawv tus lej.
