Winter Ketha: izithombe, zokulawula

Itheniphu inundu (North Lezinkumbi, isibungu ebusika) - zibuthuntu grey butterfly, empeleni esiyingozi ingadi yemifino inkathazo. ensimini yayo yomsebenzi ubanzi ngokwanele: Amacimbi lesi sinambuzane nje usuku kungonakalisa kuze 20 impande izitshalo beetroot nokolweni kwenye imitha square Ungasingatha 12-14 amakhophi izinambuzane kukhasa. Ummbila, amakhabe, canola, ugwayi, amagilebhisi, isihlahla izithombo, sunflower "ubuthakathaka" eziyisisekelo - ebusika izitshalo - hhayi uhlu oluphelele 'banambithe izintandokazi "itheniphu inundu.

Incazelo leli bhu itheniphu

Ngaphandle, leli bhu itheniphu (izithombe ethulwa esihlokweni), oyisihlobo somndeni zamalulwane ambalwa aphawulekayo: ngaphambili emaphikweni monochromatic grey noma aphuzi ansundu, ngokuziphatha nginesikali nsundu, ube isithombe esicacile sezimpawu izindawo nhlonhlo emise and bands transverse amnyama yokukhanya, ku-akhawunti shanela ngoba 30- 46 mm. wings nendluzelekazi lemicu empunga elinamathela othini zezinsikazi, ngabesilisa abamhlophe owesithupha. umzimba obuphelele - 18-22 mm. Yomuzi ekhanda nasesifubeni embozwe izinwele ezincane isinambuzane, kukhona lezi eqinile eside futhi ukuvelela izinwele ebunzini lakhe. Izimpondo: Intshebe - azalela, ikamu - kwabesilisa.

ukukhahlamezeka kwendawo indlela

Insimu ukusabalala namafosholo ebusika - zonke izifunda sezulu ngaphandle zone ezomile futhi eNyakatho Ekude. Pest bavame ukukhiqiza ezimbili izizukulwane ekukhanyeni, icala langasezantsi libe ngamawaka - amathathu, enyakatho - eyodwa. Ngo Ketha omdala esiteji amacimbi ebusika populates izingxenye yokulima Ubusika baseSiberia phansi kumuntu ka 30 cm ukujula futhi uyakwazi ukusinda ezingeni ^lokushisa -11 C. Entwasahlobo lapho ukufudumala inhlabathi +10 ^C. izinambuzane uthuthe ku ungqimba phezulu kanye pupate. Inyanga - isikhathi ukuthuthukiswa egcwele iziphungumangathi, elinesimo umbala iba nsundu ngokubomvu, 20-mm ubude izikopelo 2 ekupheleni labaqaphi elingemuva. Uvemvane luphuma isiphungumangathi ne underside we ikhanda ingxenye - ngokusebenzisa ukuqhuma. Njengoba ezikhishwe, isinambuzane ngaphansi wegazi emithanjeni esakaza amaphiko, okuyizinto esingaphansi kwesigamu sehora zifanelekile ngokwezinhloso indiza.

Izinkathi indiza mass zezimvemvane Itheniphu inundu

Phakathi no-May (in the izindawo eningizimu - kusukela ekupheleni kuka-April) iqala eminyakeni izimvemvane isizukulwane 1st, ozobakhona cishe amasonto amathathu, kwaze kwaba cishe maphakathi no-July. Kusukela maphakathi kulenyanga ekuseni iwe izimvemvane bakamalalahlengezela ezindizayo isizukulwane sesibili.

Active itheniphu ehlobo inundu izimvemvane kungaba azimisele ngokubeka ezingeni ukuphakama 20-25 cm kusukela emhlabathini ukubamba ukukhanya noma umkhombe nge fermenting Molasses (Molasses ingxenye + izingxenye ezintathu amanzi + 50 amagremu ilitha imvubelo amanzi oyi-isibilile ngayinye). Isilinganiso sobude bokuphila of itheniphu inundu butterfly - izinsuku 5-25, esiphezulu - izinsuku 35-40.

I amaningi asebenzayo Ketha ebusika, izinyathelo zokulawula edinga tekubukana, ebusuku. iminyaka Okuhlezi emqondweni ebonwe ebusuku windless, ezingeni lokushisa 12 kuya ku-15 ° ^C ngaphezu zero.

Usuku izinambuzane eziyingozi ukufihla ngaphansi kwamahlamvu ukhula, yinqwaba utshani, inhlabathi imvuthu kanye nezinye izindawo zokukhosela. Njengoba i eyengeziwe ugesi ngoba nokuvuthwa elikhulu amaqanda, izimvemvane kudle imbali umpe.

Mayelana wenzalo itheniphu inundu

ukukhiqizwa Egg siyenzeka engxenyeni Agasti lesibili futhi kuthatha indawo izitshalo yemifino, izimila eziqhakazayo ezahlukene, ukhula namasimu asethwe eceleni ubusika. Ukuze le nqubo, itheniphu inundu sekuqala ukufudumala kahle ukhetha ezindaweni herbage ongaphakeme, kokufika amabele, ummbila, beetroot kanye nezinye imifino noma insimu okuxekethile isimo somhlabathi. Amaqanda hemispherical isesimweni, elimhlophe ubisi, radially ribbed, ububanzi 0.9 mm. Omunye owesifazane uyakwazi hlehlisa kuze kufinyelele amaqanda 1,000. Ukuvundisa itheniphu inundu incike ngamandla alo. Uma kungekho nezitshalo eziqhakazayo, kukhona ukulahleka okukhulu zezimvemvane. Ngokusho okuhlangenwe nakho okuqhubekayo, nabesifazane ngaphandle ukudla wahlala izinsuku ezingu-10 futhi sibekela amaqanda 44; lapho ifakwa amandla imbali isiraphu bempilo lakhuphuka lafika ku-izinsuku ezingu-22, futhi inani amaqanda - kuze kufinyelele 860 izingcezu.

Ezindaweni nge ezomile, lapho kuye kwaba namacala sekuyaphela ukungazali izimvemvane. Ukuqala isimo esivumayo kunikela reproduction mass itheniphu inundu.

Itheniphu inundu amacimbi ngesinyathelo

Amacimbi bazalwa zingakapheli izinsuku 4-15 futhi elinesimo ikhanda ngokubomvu, isikhumba enhle, kwehlukene imivimbo amnyama ezinhlangothini, isiqu engowenhlabathi-ezimpunga 40-50 mm ubude kanye ngazimbili eziyisishiyagalombili imilenze (izinsana ezintathu, ezinhlanu besisu). Okokuqala, bahlala ngaphansi rosettes leaf noma abangaphansi kwabo futhi badla izimbobo ezincane; engxenyeni engenhla ningathinti. Futhi ngalesi sikhathi izidlo zabo eziyinhloko ukhula: emakhakhasini, quinoa, bindweed. Track by peregryzaniya kubangele umonakalo ebalulekile ukuze izithombo zokutshala imbewu ehlukahlukene kutshalwe zikakotini, ummbila. Kwakuphakathi engu lokuqala nelesibili, kuze umonakalo owenziwe izitshalo ayibanga global, kutuswa ukuba afeze izinyathelo zokuzivikela ejenti zamakhemikhali nezinto eziphilayo.

Ubukhulu umonakalo obangelwa

Umnyaka wesithathu amathrekhi zihlale ungqimba phezulu enhlabathini bese ukukhasa ngaphezulu kuphela ngenjongo yokwanelisa indlala. Phakathi nobusuku, izimo ezinjalo ziyathandeka enamandla okubhubhisa kuze izitshalo kweshumi futhi sidla izitshalo ezahlukene yemifino, unyaluthi ushukela isithombo sebhitrudi, ukotini, amakhabe, ummbila. Manje badla izimbobo amaqabunga, bese badle onke amaqabunga, kusale kuphela vein zungeza.

kuqala izibungu isizukulwane kubangele umonakalo ngo-June nango-July, bese liyazika enhlabathini kumuntu ka 3-10 cm ukujula pupate. Umhlangano omkhulu kunayo yonke imbangela umonakalo ezolimo isizukulwane sesibili amacimbi kokulimaza etshaliwe imbewu kanye izithombo sekukhona wokudla ebusika.

Itheniphu inundu impendulo ke

Ukuze kuncishiswe isibalo cutworm ebusika futhi ukunciphisa umonakalo obangelwa emhlabathini waso kudinga inqubo ngokucophelela futhi ngesikhathi esifanele, ikakhulukazi oqondisa umsebenzi ku:

• ukhula Global - ukudla itheniphu inundu;
• Ukulima ezijulile, pre-ukucutshungulwa kanye inter-irowu hoeing, kubangela ukubhujiswa iningi iziphungumangathi kanti izibungu izinambuzane eziwuhlupho;
• uchelela ku insimu;
• kokuqhuba ukuhlwanyelwa ekuseni sunflower, ushukela isithombo sebhitrudi kanye nezinye izitshalo, ukunciphisa harmfulness of isizukulwane sokuqala izinambuzane;
• kuqondana ukutshalwa umsebenzi ensimini kanye isikhathi mass Iqanda-kubekwa;
• ukususwa komgwaqo ekutshaleni futhi eduze kwamasiko ukhula zezimbali - lesi sinyathelo kuhloswe Ukuwohloka abalulekile lokwela amandla.

Ukulwisana bhu ebusika ngempumelelo lapho sishaye izitshalo amakhemikhali ezifana "Fitoverm", "Decis Ezingeziwe", "Agrovertin". Nge cutworms ebusika zingalawulwa ngu inqubo yemvelo: ukukhululwa kwe Trichogramma, edingekayo ukuze afeze ngesikhathi oviposition mass.
