Isigaba sesibili sokuthuthukiswa kwe-cockchafer (aka Khrushchev) ngemuva kweqanda yi-larva. Ngezinye izikhathi kubizwa boroznyak noma i-chorobak.
Kuyaziwa kakhulu phakathi kwabalimi nabalimi ngenxa yokuvuthwa kwayo, futhi cishe inkathazo yokuqala imifino, iberry, isihlahla kanye nezitshalo zehlathi.
Ngalo umsebenzi izibungu ze-beetle ye-May zingancintisana nezimpungushe kanye nabantu abadala base-Colorado amazambane beetle, kanye nama-bears.
Izitha zemvelo zama-larva ziye zaba njalo umhlabathi wesibhakabhaka, ama-hedgehogs, ama-moles, ama-starlings, ama-blackbirds, ama-rook futhi ngisho izimbongolo. Uma abanikazi beziqephu zezolimo kudingeka babhekane nezigubhu ngokwabo, kubalulekile ukucabangela ubuciko nendlela yokuphila yale nambuzane.
Incazelo
Ibukeka bunjani njenge-beetle? Izibungu zikhula kuze kube ngu-4-7 cm ubude, banomzimba omkhulu wokukhanya umbala wobisi obomvu (njengoba kuboniswe esithombeni esingezansi), egcwele izinwele ezincane, ingxenye yomsila yanda kancane futhi imnyama.
I-Larva ye-Beetle ye-May - isithombe:
Uma ubukeka ngokuqhathanisa i-larva ne-beetle omdala, owokuqala uzoba kancane kancane imago ngobukhulu. Umzimba ogubhukile unomqhele ohlosiwe kaningi umbala obomvu noma ophuzi, onamathenda amabili ama-brown namagciwane amancane, okusiza hhayi kuphela ukugaya ukudla, kodwa futhi nokumba umhlabathi.
Ngaphambi komzimba kunezinyawo eziyisithupha zokubamba. Emaceleni munye umugqa kungabhekwa njengento encane amanothi ezimnyamanjengamehlo Esimweni sokuthula esiphezulu, umzimba we-larva uba ngu-C.
Ukuhlukanisa kanjani ibhere?
Indlela yokwahlukanisa izimpungushe zeMebotbot ezivela ku-larva larva? I-larva ye-cockchafer ingadideka kuphela isibhamu sethusi kanye namanye ama-grubs. Isigaba sesibili sokuthuthukiswa kwebheyi ngemuva kweqanda kufana ikhophi encishisiwe umuntu omdala. Imago kuphela yinto emnyama kakhulu, futhi kukhona amaphiko. Inambuzane elula ngesayizi ayidluli ku-3 cm nangaphandle kakhulu kakhulu njenge-medvedka encane (bheka isithombe ngezansi).
Kubalulekile ukukhumbula izici zangaphandle zegumbi leMeyi-beetle, ukuze zingalithandani nabanye, hhayi izibungu eziyingozi. Isibonelo, isibungu se-bronze asilimazi ama-rhizomes, kodwa sithuthukisa inhlabathi ngemikhiqizo ye-waste, futhi cishe okungenabungozi. Ungabahlukanisa ngombala wamachashazi ezinhlangothini, ikhanda elincane kanye nemilenze emifushane emifushane eluhlaza.
Maybot and Medvedka larva: Uyini umehluko? Isithombe sebhere lesila:
Yini edlayo?
Yini ama-grubs adla? Uma i-imago ngayinye inezitsha ezilula kakhulu, i-larva ye-beetle ye-May edume ngokuvunguza okukhulu. Ngenxa yezimpande ezinamandla, izibungu zidla ukudla okuyimifino eqinile, ngezinye izikhathi zibopha ngisho nezimpande ezinamandla kunazo zonke zezihlahla zakudala.
Ekuqaleni kokuthuthukiswa kwayo, i-boroznyak idla kakhulu kakhulu ama-rhizomes ezitshalo nezihlahla (cherry, larch, birch, ngesihlahla se-spruce, i-oki, umsedari, njll), kanye nama-humus yemifino.
Lapho sekuqala ukushisa, i-larva ifuna ukujula ngaphansi komhlaba (kuze kufike emitha) ukuze ilinde amakhaza, futhi ngasentwasahlobo ibuye isondele eduze. Lapho uzodla izimpande ze-shrub (currant emnyama) nezinye izitshalo, kufaka phakathi imifino.
Ukufinyelela eminyakeni emibili, i-larva iqala ukudla izimpande ze-woody, ama-bulb, amazambane nezilimo eziyizigaxa, i-turnips nokunye
Ungayithola kanjani?
Lapho ungathola khona izibungu ze-beetle yamaMeyi? Indawo yokuhlala, njenge Khrushchev, kanye nezimpungushezi zisakaze emifuleni nasemahlathini, ezigodini ezisogwini, emadlelweni nasezindaweni zezolimo. Isimo esihle kakhulu kubo - inhlabathi emanzi nefudumele, ecebile izakhi (humus) futhi kulula ukuyikhulula.
Ehlobo sasehlobo, izimpungushe ziqala ukuxosha amaqanda emigqeni ephakathi kwamasimati namahlamvu. ekujuleni okujulile (ngaphansi kuka-20 cm). Uma inkathi ishisa, ngezimvula ezingavamile, izimpungushe ze-beetle zeMeyi ziyahamba ngaphansi komhlabathi ezingaphezu kwesigamu semitha.
Okunye okunye indawo oyithandayo izimpungushe zibhekwa njengezigcwele ukhula nezintaba zasendle, izindawo ngaphansi kwezimpande zemithi ehlukahlukene, kanye neziqu ezindala ezibolile.
Bangaki abaphilayo?
Ngokujwayelekile, umjikelezo wokuphila ogcwele we-furrow ukhona Iminyaka emine, ngenxa yalokho, i-beetle yesilinganiso samaphakathi izohlala iminyaka engaba ngu-5. Ngonyaka odlule wokuphila, i-larva iyangena isigaba se-pupal, ukuze emva kwezinyanga ezimbalwa zibe nguKrushchev.
Yenzani umonakalo?
Amahlathi amaningi nezitshalo zezolimo ahlushwa umsebenzi obalulekile wezibungu ezivuthiwe ze-Beetle kaMeyi. Abantu abasha abafaki umonakalo omkhulu - Ekuqaleni, kuphela izimpande ze-herbal ezifakiwe ekudleni kwazo.
Ukuqothula izimpande nezilimo eziyizigaxa ezingaphansi komhlaba, umhlaba owehlayo awukwazi nje ukwehlisa ukuthuthukiswa nokukhula kwezitshalo eziwusizo, kodwa futhi uvumela abaningi izifo kanye nezinambuzane ukungena ezingxenyeni ezilimele.
Kusukela emasimini ezihlahla ezivela emasongweni ama-Khrushchev bahlupheke ama-apula, ama-apricot, amapheya, njll. Ngisho namajikijolo afana nama-strawberry nama-strawberries basengozini, uma ngaphansi komhlaba emibhedeni izibungu ezinesihlungu ziyakhiwa.
I-Larva ye-beetle yaseMeyi esiteji se-pupal - isithombe:
Iyini imiphumela?
Ngaphandle kokuvuna okulahlekile kwamazambane, ummbila kanye neminye imifino, izinsimu ezinezihlahla zezithelo kanye nemibhuloho ezihlahleni zingalahlekelwa kakhulu. Ngenxa yezibungu zesimiso sezimpande zesitshalo funa ngokushesha, bese ufa.
Kuphela ngenxa yokulawulwa kwemvelo yabantu kanye nabantu, izimpungushe ze-beetle kaMeyi azibhubhisi amahlathi aphelele kanye nezindawo ezinkulu zasemapulazini. Kusukela ekudleni kwabantu abasha, uboya obunamehlo bungalahlekelwa ngotshani obuntshani, kanti ukudla kwezihlobo ezindala kuyingozi kakhulu emithini eminingi ye-coniferous kanye neyomuthi.
I-Maybot izibungu ziyisikhathi eside zisungula ngokwazo usongo olukhulu ezitshalweni zamahlathi nezitshalo. Ngesikhathi sokuphila kwabo isikhathi eside, ama-fallow amazwe akwazi ukudla kakhulu ukudla okutshala njengezilimo eziyizigaxa zamazambane, kodwa ukulimaza kakhulu uhlelo lwempande yamasimu nezihlahla zezithelo.
Basebenzisa iningi lempilo yabo ngaphansi komhlaba ngifuna ukudla nangesikhathi sokubusika. Isakhiwo somzimba sibavumela ukuba bafunde ngokukhululekile amavesi angaphansi komhlaba kuya ezimpandeni ezithandekayo, abazitholayo ngezimiso zabo.
Yilokho amazambane adliwe yi-larva ye-beetle ibonakala sengathi:
Ukubhekana ngokuphumelelayo nezilokazane ezinamhlophe ezinomzimba kuphela ukuhlanganiswa ngesandla. Kule njongo, inani elanele lokukhiqiza amakhemikhali nama-biological. Njengezindlela zokulwa, ukuze ulondoloze isivuno, izicupho ezikhethekile zibekwe, umquba ugcinwa ngokucophelela ngaphambi kokufaka umanyolo.
Izimpungushe ze-Khrushchev zingaletha inzuzo enkulu imvelo nomuntu. Bahlala endaweni eyigugu emaketangeni amaningi okudla, okufaka isandla ekwenzeni umoya.
