Plum npauj nyob yuav luag txhua qhov txhia chaw, ua rau tsis tsuas yog plums nrog plum cherry, tab sis kuj tseem muaj pos, txiv duaj, apricots, thiab me ntsis tsawg dua cov txiv hmab txiv ntoo thiab txiv ntoo qab zib. Cov plum wormy yog, raws li txoj cai, qhov tshwm sim ntawm kev puas tsuaj ntawm cov kab no. Koj tuaj yeem thiab yuav tsum tawm tsam tus yeeb ncuab, txwv tsis pub koj yuav tsis tau tos kom sau qoob loo zoo

Ntsib kab tsuag

Kab tsuag yog npauj npaim nrog lub tis dav ntawm 13-15 hli. Lawv cov tis pem hauv ntej yog xim av xim av nrog rau me ntsis tint ntawm cov xim violet, thiab cov tis tom qab yog grey-xim av.

Qhov loj ntawm plum npauj qe yog 0.7 hli; lub qe lawv tus kheej yog qhov ua kom pom tseeb thiab tiaj tus, sib npaug me ntsis, xub pib lawv dawb, thiab tom qab ntawd daj-ntsuab. Kab ntsig 12 - 15 mm ntev, cov tub ntxhais hluas yog daj dawb, cov laus yog daj ntseg daj, nrog lub taub hau tsaus nti thiab ob txhais ceg. Pupae yog lub teeb xim av, ntev li 7 - 8 hli, nrog lub ntsej muag sib sib zog nqus.

Overwintering ntawm kab ntsig uas tau ua tiav lawv txoj kev pub noj yuav tshwm sim nyob rau hauv kab laug sab cocoons hauv cov khib nyiab cog, hauv qab me ntsis tev tawm ntawm cov tawv ntoo ntawm tsob ntoo, tawg hauv cov tawv ntoo, thiab tseem nyob hauv txheej txheej ntawm cov av. Sai li qhov nruab nrab txhua hnub kub tshaj qhov pib ntawm 10 degrees, tom qab 10 - 15 hnub cov kab mob parasites pib ua rau menyuam (feem ntau nyob rau tib lub sijhawm, cov paj ntawm ntau yam lig ntawm plum pib tev tawm). Cov txheej txheem menyuam kawm ntawv tau txuas ntxiv me ntsis hauv lub sijhawm (txawm li cas los xij, nrog rau theem tom ntej ntawm kev txhim kho) thiab yog kwv yees li 35 - 45 hnub. Kev loj hlob ntawm menyuam dev yuav siv sijhawm li 15 - 26 hnub, thiab tom qab lwm 12 - 15 hnub, koj tuaj yeem pom pom xyoo loj heev ntawm npauj npaim, qhov haujlwm loj tshaj uas poob rau lub sijhawm sib nrug tom qab 17 teev (huab cua kub yuav tsum yog yam tsawg kawg nkaus) 16-17 degrees). Sai li qhov kub pib poob mus rau 12-13 degrees, tsis yog tsuas yog xyoo ntawm cov kab mob parasites xaus, tab sis kuj tseem tso qe. Qhov ntsuas kub zoo tshaj rau lawv yog 24 - 26 degrees.

3 - 5 hnub tom qab tshwm sim, poj niam nteg qe ntawm thaj chaw pom kev ntawm cov txiv hmab txiv ntoo - yuav luag ib txwm nyob rau ib lub sijhawm, tab sis nws tshwm sim hauv 2 - 3. Qe tseem tuaj yeem tso rau ntawm qhov qis ntawm nplooj (raws li txoj cai, nruab nrab) thiab qis dua qib ntoo ntoo). Tag nrho fertility ntawm poj niam ntawm cov yeeb ncuab plum yog 50 - 90 qe. Kev txhawb siab ntawm kab ntsig tau sau tseg 5-10 hnub tom qab. Lawv tam sim ntawd pib txav mus los ntawm cov txiv hmab txiv ntoo - lub sijhawm "taug kev" tuaj yeem nyob ntawm ob peb feeb mus rau ntau teev.

Ua ntej nkag mus rau hauv cov txiv hmab txiv ntoo, cov kab ntsig tau khawb cov cheeb tsam uas tau xaiv nrog cobwebs, thiab twb nyob hauv qab lawv lawv pib tom rau ntawm daim tawv nqaij. Sai li lawv nyob hauv cov txiv hmab txiv ntoo muaj kua, lawv npog lub qhov nrog cov txiv hmab txiv ntoo nrog cov cobwebs. Cov cheeb tsam puas tau yooj yim los suav - cov dej me me ntawm cov pos hniav tau tsim rau lawv. Lwm 3 - 5 hnub tom qab, kab ntsig tsim ntau txoj hauv kev hauv cov kua txiv hmab txiv ntoo. Mus txog qhov txiav, lawv tam sim zom los ntawm cov pob, uas ua rau ua rau muaj kev cuam tshuam hauv kev ntws ntawm cov as -ham rau cov txiv hmab txiv ntoo thiab kom tsis muaj kev loj hlob. Cov txiv hmab txiv ntoo cuam tshuam, tau txais cov xim ntshav thiab ua rau lub sijhawm ua ntej, poob sai. Hauv cov txiv hmab txiv ntoo hluas, cov pob txha tsis khov nrog cov ntoo tau raug puas los ntawm kab mob, hauv cov txiv hmab txiv ntoo uas paub tab, lawv zom tag nrho cov nqaij nyob ze cov pob txha los ntawm lawv, thiab cov kab noj hniav tau tsim muaj cov cab nrog lawv tus kheej tso. Lub sijhawm txhim kho rau cov kab ntsig no yog kwv yees li 20 txog 30 hnub.

Yuav ua li cas kom tshem tawm

Arthropod parasites tuaj yeem txo tus naj npawb ntawm cov neeg tsis tau caw tuaj koom, thiab kwv yees li 5-10% ntawm plum npauj tau kis tus kab mob entomophages.

Tawm tsam txhua tiam neeg ntawm cov yeeb ncuab, cov ntoo plum tau txau nrog ntau yam tshuaj tua kab. Kev pib kho feem ntau poob rau thawj theem ntawm kab ntsig kev txhawb siab. Rau kev txau, cov neeg sawv cev xws li gardona, phosphamide, dursban, cydial, zolone, antiio, metathion, karbofos, chlorophos thiab metaphos feem ntau siv. Tso tshuaj tsuag dua tsis pub dhau 15 hnub tom qab. Thiab 15 hnub tom qab, rau qhov lig ntau yam ntawm plums thiab cherry plums, cov tshuaj txau thib peb tau teeb tsa (txawm li cas los xij, tsis pub dhau ib hlis ua ntej pib sau qoob).

Cov txiaj ntsig tau zoo tuaj yeem ua tiav los ntawm kev siv pheromone (funemon) rau cov txiv neej tsis meej pem. Nws tseem yuav ua tau zoo los khaws cov kab mob wormy tas mus li thiab siv txhua yam ntawm txoj hlua khi (ua los ntawm cov ntawv corrugated, daim pam thiab lwm yam ntaub ntawv). Ntawm cov kab nrog cov ceg ntoo pob txha, nws yog ib qho tseem ceeb kom tsis tu ncua tshem tawm cov tawv ntoo tuag. Tsis tas li, txhawm rau txhawm rau txo cov pej xeem ntawm cov yeeb ncuab, hauv av hauv tsob ntoo-lub voj voos yuav tsum tau khawb tas li, thiab thaum lub caij nplooj ntoo hlav thaum ntxov, cov ceg ntoo thiab cov ceg ntoo yuav tsum tau ntxuav nrog cov txiv qaub.
