Kodi Mumayendetsa Bwanji Magnolia Scale?

Wowerenga posachedwapa anafotokoza zochitika pamtengo wake womwe umatanthauzira bwino matenda omwe amapezeka ndi tizilombo ndipo timayankha momwe tingagwiritsire ntchito magnolia scale ( Neolecanium cornuparvum , Thro). Nazi momwe imelo yake imawerengera:

"Ndili ndi mtengo wa magnolia womwe ukuwoneka wofiira ndi wowonongeka. Nditayang'anitsitsa, ndinawona mamba pa nthambi zomwe zimawoneka ngati nkhwangwa pamakungwa. Ndinachotsa nkhanza zonse ku nthambi ndikudula nthambi zakufa.

Kodi pali chilichonse chimene ndingathe kupopera pa mtengo wa magnolia kuti ndikhale ndi mwayi wopulumuka? "

Kodi Mumayendetsa Bwanji Magnolia Scale?

Kulongosola kwake kunali koyenera. Chimene iye anali nacho, ndithudi, amatchedwa magnolia "scale." Chinthu choyamba chimene eni eni nyumba ayenera kuzindikira pozindikira momwe angagwiritsire ntchito magnolia mlingo ndikuti amawoneka ndipo amachita zochepa ngati tizilombo.

Zamoyo zamoyo za magnolia zimayendetsedwa ndi nthawi yaitali zomwe zimangowoneka ngati mwambi "kuphulika pa chipika." Koma musalole kuti maonekedwe awo osaoneka akupusitseni, chifukwa akumwa madzi anu. Pali magulu awiri a anthu ambiri (ngakhale pali mitundu yambirimbiri ya mitundu): mitundu ya zida zankhondo ndi mitundu yofewa. Magnolia scale ndi gulu lomaliza.

Chifukwa cha maonekedwe awo "osapitirira," komabe, anthu amawombedwa nthawi zambiri akamaliza umboni. Choipa kwambiri, iwo angaganizire molakwika vutoli ngati vuto la nkhungu kapena nthendayi (nyerere zimakopeka ndi chisa chodetsedwa ndi magnolia scale, monga momwe tafotokozera m'nkhani ino yokhudza mankhwala oletsa tizilombo ).

Ndipo inde, pali mankhwala ophera tizilombo omwe mungagwiritse ntchito polimbana ndi vutoli. Koma pofuna kugwiritsira ntchito magnolia mphamvu, ndizofunikira kuti mumvetsetse moyo wa tizilomboti, chifukwa chakuti nthawi yomweyi ndi yomwe imapanga nthawi yoti ipiritsire ndi tizilombo kuti tipewe magnolia.

Moyo wa Magnolia Scale

Tizilombo toyambitsa matenda timadutsa muyeso (magawo) mu moyo wawo wotchedwa "instars." Dipatimenti ya Penn State ya Entomology imalongosola moyo wa tizilombozi; chidule chafotokozera kwawo:

Tizilombo ta tizilombo ta tizilombo ta tizilombo ta tizilomboti timene timapanga nthambi za mtengo zomwe zimatchedwa "nymph" instar. Nymphs awa amayamba kudyetsa mu kasupe ndikufika kukhwima pakati pa chilimwe, pomwe nthawi yothandizira imapezeka. "Azimayi amatha kubereka achinyamata omwe amatchedwa" crawlers kumapeto kwa August kapena kumayambiriro kwa September. " Koma, posakhalitsa, kukwawa kuima, ndipo iwo amamatirira ku nthambi zomwe padzakhala overwintering - motero kutibweretsera mzere wathunthu.

Nthawi Yopopera ndi Tizilombo Tophera Kupha Tizilombo Tosiyanasiyana

Pofuna kuteteza magnolia kuchuluka, muyenera kupopera tizilombo toyambitsa matenda (mwachitsanzo, malathion kapena acephate) panthawi yoyenera mu moyo wa tizilomboti. Tizilombo tizilombo toyambitsa matenda timakhala tizilombo toyambitsa matenda pa nthawi yomweyi m'moyo wawo kusiyana ndi nthawi zina, ndipo nthawiyi nthawi zambiri imatha nthawi ya chilimwe. Dipatimenti ya Cornell Entomology imalongosola kuti, pokhapokha tizilombo ting'onoting'ono tikupita patsogolo pa malo othamanga m'kati mwa moyo wake, "zowonongeka zimakhala zovuta, zomwe zimachititsa kuti asagwiritse ntchito tizilombo toyambitsa matenda."

Popeza tizilombo tili pa malo othamanga kumapeto kwa chilimwe, ndiye nthawi yabwino kwambiri yopangira (cholinga cha September). Ngati mukufuna kuyesa tizilombo toyambitsa matenda, yesani mafuta a neem .
