Ukuba unemithi ye-elm, nokuba yeyoluphi uhlobo lwe-Ulmus okanye ziyiZelkova, usenokuba ubonile ezinye Xanthogaleruca luteolaOko kukuthi, kwe elm qongqothwane. Esi sisinambuzane esincinci kodwa sinokonakalisa kakhulu le mithi.
Ukongeza, iphindaphindeka kakhulu kwaye ngokukhawuleza kangangokuba eyona nto sinokuyenza kukuthatha amanyathelo okuthintela ngokuchasene nayo, kuba, nangona ingayi koma, iyenza buthathaka kakhulu. Makhe sibone indlela yokuyiphepha.
Yintoni na?
Yiyo ubushushu beethung yosapho lakwaChrysomelidae olubizwa ngokuba yi-elm beetle okanye i-galeruca. Izalelwe eYurophu, nangona namhlanje ikwafumaneka eMantla Melika nase-Australia.
Ngaphambi kokuba ube mdala, kuhamba ngamanqanaba ahlukeneyo:
- Egg: tyheli ngombala, kwaye owasetyhini ubeka izihloko ezifikelela kwiiyunithi ezingama-25.
- umbungu-Ihlala imnyama, ngamanye amaxesha imnyama ityheli, enemigca eliqela yamachaphaza nasemacaleni. Imilinganiselo yokufikelela kwi-13mm ubude.
- Pupa: Lu-orenji-tyheli ngombala kunye nokumakisha okumnyama.
- Indoda enkulu: Imthubi naluhlaza ngombala, inebala entloko kunye nebhanti ebanzi emnyama emiphethweni. Ilinganisa i-6 ukuya kwi-8mm ubude.
Nguwuphi umonakalo oveliswayo?
Ukusukela entwasahlobo ukuya ngasekupheleni kwehlobo (ukuba imozulu ifudumele, inokuhlala ikwasebenza kude kube kokwindla) iya kuzondla kumagqabi, ngakumbi ezantsi. Ke into esiza kuyibona yile Amagqabi avuzayo.
Ukuba isampuli incinci kakhulu kwaye inambuzane isasazeke kakhulu, inokuma.
Kufuneka wenze ntoni ukuyilawula?
Iyeza lendalo
EYurophu i-elm beetle inotshaba lwendalo: i-wasp I-Oomyzus gallerucae. Ke ngoko Ukuba sikwezwekazi elidala, eyona nto ilungileyo kukwenza konke okusemandleni ukutsala oonomeva, njengokutyala izityalo zokuhombisa kwaye ungasebenzisi iikhemikhali.
Enye into ebaluleke kakhulu, nokuba siseYurophu okanye akunjalo, yile thenga iisampulu ezisempilweni, kuba kungenjalo siza kuba semngciphekweni wokosulela abo sele sinabo egadini.
Kwimeko apho sifuna ukusebenzisa imveliso enokusinceda siyiphindise okanye siyiphelise, Ndicebisa ukusetyenziswa umhlaba owomileyo ngokukhawuleza xa kuqala intwasahlobo. Sidibanisa i-35g yoluhlobo lomhlaba (eneneni ngumgubo ocolekileyo omhlophe kakhulu) ne-1l yamanzi, kwaye sitshiza onke amalungu esityalo kakuhle. Ungayithenga apha.
Unyango lwekhemikhali
Azisebenzi kakuhle, kwaye ziyingozi nakwindalo. Kwiimeko ezigabadeleyo, ukusongelwa komboko ngamabhanti okubulala izinambuzane kunganciphisa uhlaselo kunyaka olandelayo, njengoko oko kungabulala imibungu.
Ndiyathemba ukuba iluncedo kuwe kwaye ungagcina ii-elms zakho zikhuselwe.
