Inkathazo eyingozi kunazo zonke ye-conifers ingabizwa ngokufanele ngokuthi i-pine sawfly - inambuzane engabangela umonakalo omkhulu esihlahleni noma ngisho nokuyichitha.
Izihlahla zikaphayini zihlushwa kakhulu yizinambuzane, ikakhulukazi ezineminyaka engama-20-40, noma kunjalo, izinhlobo zezitshalo zokuhlobisa zivame ukuhlasela ukuhlasela okukhulu kwezinambuzane.
Ukuze uvikele imifula ye-coniferous futhi uthathe zonke izinyathelo ezidingekayo zokuvimbela nokulwa nama-sawflies, kubalulekile ukuthola ukuthi ubhekene nobani.
I-Sawfly evamile
I-Larvae
Umbala womzimba wesidalwa samanga salezi zinambuzane ezihlukahlukene kusuka obala ophuzi kuya ohlaza. Esikhathini esiswini se-larva kukhona amacwecwe amnyama aphezu komlenze ngamunye wamanga, leyo nombolo kusukela ngo-18 kuya ku-22. Inhloko iyabhanya, iyindilinga, imnyama noma imnyama. Ubude begumbana lamanga lufinyelela 25 mm.
Umuntu omdala
Ukukhula owesifazane I-sawfly evamile ibonakala ngezigaba ezingu-6, kanti owesilisa udlula iminyaka engu-5. Insikazi yesinambuzane esidala sinombala womzimba we-convex kusuka obala ophuzi obomvu. Ngaphandle komjikelezo kukhona amaconsi amnyama. Umshayeli we-Antenna. Ubukhulu besifazane besifazane abudluli 10 mm.
Umbala wesilisa ngokuvamile emnyama noma emnyama, ama-paws abomvu. Ubukhulu bomuntu wesilisa buyingcosana (6-8 mm). I-Antenna ixube kakhulu.
I-Sawfly Redhead
I-Larvae
Umzimba we-sawfly larva obomvu unayo umbala ompunga okhanyayo. Umdwebo omhlophe ubonakala ngemuva, ezinhlangothini ngaphezu komlenze ngamunye kunamabala amnyama ku-speck elula. Inhloko iyindilinga, ikhanya, imnyama. Ubukhulu bombumba wamanga aludluli 25 mm.
Umuntu omdala
Idatha yangaphandle yabantu abadala bobabili izinhlobo ziyafana.
Amandla
Ngesikhathi sokuqala kwentwasahlobo, izibungu eziphahlazekayo zidla ezinaleni zasendulo zepine. Okulandelayo, izinambuzane ziya emahlumela amancane, zidale umonakalo hhayi nje ezinaliti kuphela, kodwa futhi nasezingxenyeni ezincane.
Izibungu "zenza" ngamaqembu, zidla izinaliti, ngenkathi zishiya penechki kuphela. Isibungu esisodwa samanga singabhubhisa izinaliti ezingama-40.
Yimuphi umonakalo owenzayo
Akuzona izibungu kuphela, kodwa futhi izinambuzane ezindala ezidla izinaliti zibangele umonakalo emasimini e-coniferous. Ngemuva kokudla kokuqala izinaliti, ziyoma, iphenduka ephuzi bese iwa.
Endabeni lapho kungekho ukudla okwanele, le nambuzane idla amagxolo kanye namahlumela amancane, okuholela ekufeni kwamagatsha emgqeni. Ngokuhamba kwesikhathi, lesi sitshalo silahlekelwa amandla, siwagula futhi, ngenxa yalokho, siyafa. Uma i-sawfly yephayini ihlasela umuthi omncane wephayini, ngokuqinisekile ngeke ufe eminyakeni engama-3-4.
Ngenxa yokwehla kwesitshalo, kuba yisisulu esilula kwezinye izinambuzane futhi sibhekene nezifo eziningi.
Uhlu lwepine sawfly oluvela kwezinye izinhlobo
Kumele kuqaphele ukuthi ukuqubuka kwezidakamizwa endaweni ethile ethize kukhona izici eziningi zalesi sifo, kodwa kwenzeka ukuthi ukukhiqiza kwenzeka ezindaweni ezinkulu.
Ngonyaka we-pine sawfly unikeza izizukulwane ezimbili - emavikini okugcina entwasahlobo naphakathi kwehlobo. Ukwanda kwenani lalezi zinhlobo kufakazelwa ukwanda kwezinga lokushisa kwemvelo - okuphakeme, ngokushesha ukuthuthukiswa kwenzeka.
Uma ukwehla kwomoya umswakama wengezwa kwisilinganiso sokushisa, izimo ziba ngcono ekuthuthukiseni ukuphikiswa kwezinambuzane emiphumeleni ehlukahlukene yokulimaza.
Okwamanje ukuze uqaphele izithombe ze-pine sawflies:
Izindlela zokulawula
Emahlathini okuthiwa yi-coniferous, ukunqoba inkathazo kunzima kakhulu, kepha kukhona ezinye izindlela zokulawula ezikhona, futhi zingasiza ekuqedeni izinambuzane ezilimazayo.
Glue izindandatho
Ungakha indandatho efanayo ngokusebenzisa i-glue phansi kwesigxobo somuthi. Esikhathini lapho izibungu ziqala ukuhla Ukuze benze i-cocoon, bayowela esiqhingeni esibekwe futhi ngokushesha bazofa. Ngaphezu kwalokho, isicupho seglue asivumeli izimpungushe zikhuphuke esihlahleni esihlokweni somuthi.
Kubalulekile: I-glue kufanele ingabi namanzi futhi ingabe isomile!
Ukuphalaza ngamakhemikhali
Izitshalo zamakhemikhali kufanele zifakwe ngaphandle kwezihlahla ezithintekile kuphela, kodwa nazo zizungezwe.
Uma le nambuzane itholakale ensimini yasemuva, ukulwa nalesi sifo kufanele kuqalwe ngokushesha ngangokunokwenzeka.
Izindlela zokubhujiswa zinjengoba:
- Ukutshala utamatisi ohlahleni eduze kwesitshalo esithintekile okhiqiza izinambuzane ezithile ezidubula ama-enzyme.
- Ukumba isitshalo esithintekile, okwenza kube nzima ukudlulisela inambuzane komunye umuthi.
- Ukutshala izitshalo tincture of lwesinaphi, umhlonyane, ugwayi.
- Sebenzisa ukubhubhisa izinambuzane ezikhethekile eziphilayo.
- Ukuqoqwa kwama-sawfly izibungu.
Kungenzeka ukulwa nalesi sifo, kodwa izinyathelo zokulawula zingase zinganiki ngaso sonke isikhathi umphumela omuhle. Indlela ngayinye inhle kuphela esiteshini esithile sokuthuthukiswa kwezinambuzane, ngakho-ke okukhethwa kukho okungcono kakhulu kungaba ukuvimbela ukubukeka kwe-sawfly.
Kunezinyathelo eziningana zokuvimbela lokhu:
- Ukusabalala kwenkathazo kuxhomeke ngokuqondile esiteshini sezulu. Uma isibikezelo sokuphela kwentwasahlobo - isiqalo sehlobo sithembisa isimo sezulu esibucayi nesimeme, ukubonakala kwama-sawflies ezihlahleni kuqinisekiswe ngu-85%. Ezindaweni ezincane zezitshalo ze-coniferous, kubalulekile ukunikeza umswakama okhulayo lapho izibungu ezibulala izinambuzane zifa khona.
- Uma kunokwenzeka, ukutshala amahlathi ahlanganisiwe (okhuni kanye ne-coniferous) kuyoba yindlela engcono kakhulu. Ukuba khona kwamahlathi ehlathini kuvimbela izinambuzane ezindala ukuba zingadli ukudla.
- Isitha esiyinhloko sale nkathazo eyingozi iyinyoni. Ukuheha izinyoni eziningi ngangokunokwenzeka ngokuzidla nokuzakhela izindlu.
I-Pine sawfly - izinambuzane eziyingozi, ezikwazi ukuchitha amahlathi eminyakeni embalwa. Ukunganaki izindlela zokuvimbela, ukungathathi izinyathelo zokulwa nezinambuzane eziyingozi, izitshalo ze-conifer zizobhujiswa.
Ukufingqa, sikunaka ividiyo mayelana nama-sawflies wephayini:
