Iwe Unotonga Sei Magnolia Scale?

Tsanangudzo yake yaiva yakakodzera. Zvaaiva nazvo, zvechokwadi, ainzi magnolia "scale." Chinhu chokutanga icho vagari vepamba vanofanira kuziva mukudzidzira nzira yekudzivirira magnolia chikamu ndechokuti inotarisa uye inoshanda zvishomanana zvakadai sezvipembenene zvakafanana.

Hupenyu hwehupenyu hwemaginelia hutachiona hunotungamirirwa nenguva yakareba iyo iyo inongoratidzika semutsananguro "bump pane ganda." Asi musarega kuonekwa kwavo kusina mhaka kukupusa iwe, nokuti vari kuyamwa mvura inobva mumiti yako. Iko maviri mapoka evanhu vakuru (kunyange kune zviuru zvemarudzi akasiyana-siyana): nhumbi dzakashongedzerwa nemaviri uye miviri yakaderera. Magnolia chikamu ndecheboka rekupedzisira.

Nokuda kwekuonekwa kwavo "kusina upenyu," zvakadaro, vanhu vanowanzotorwa vasina-varindi apo ivo pakupedzisira vanopupurira uchapupu hwehutachiona. Zvakanyanya kuipa, vangave vasina kuongorora mamiriro acho ezvinhu sechinetso chekuumba kana kunyange dambudziko rinosuruvarisa (nyuchi dzinokweverwa kuuchi chinyanyiso chinokonzerwa ne magnolia scale, sezvinotsanangurwa munyaya ino pamusoro pehutano hwehutachiona ).

Uye hongu, pane chipukisi chinopupurira iwe unogona kushanda kurwisa dambudziko racho. Asi kune magnolia inobudirira kutonga, zvinokosha kuti iwe unzwisise hutachiona hwehupenyu hwehupenyu, nokuti hutano hwakadaro hunotarisa nguva yekuputira nechirwere chepukisi kuti utonge magnolia scale.

Upenyu Hwakanaka hweMagnolia Scale

Nhamba yezvipembenene inopinda nepakati pezvikamu (phases) muhupenyu hwavo hunonzi "maitiro." I Penn State Department of Entomology inotsanangura upenyu hwezvipembenene izvi; chidimbu chekutsanangurwa kwavo chinotevera:

Iyo insect overwinters pamagariro emapazi emuti mune izvo zvinonzi "nymph" instar. Iyi nymfu inotanga kudya muchirimo uye inosvika pakukura mukati mezhizha, panguva iyo kubata kunowanikwa. "Madzimai gare gare anobereka vana vaduku vanonzi chikwadzi chinopera muna August kana kutanga kweSeptember." Asi, nguva pfupi mushure mokunge, kutamba kunomira, uye ivo vachabatisisa kumashizha ayo apo overwintering ichaitika-nokudaro kutitorera denderedzwa rakazara.

Nguva Yokusvibisa NeInsecticide Kuti Uuraye Nyaya Dzakakuvara

Kuti uchengetedze magnolia scale kubudirira, unofanira kuparadzira mushonga (semuenzaniso, malathion kana acephate) panguva yakakodzera muhupenyu hwehupembenene huno (iko, kana uri muchitamba chechikwata). Izvi zvipembenene zvinowanzoshungurudzwa pamashirasira panguva iyoyo chaiyo muhupenyu hwavo kupfuura dzimwe nguva, uye nguva iyoyo inowanzoguma kwezhizha. Dhipatimendi reConceptell Entomology rinotsanangura kuti, kana chirwere chechikwereti chichipfuurira mberi chechikwereti chechikwereti muhupenyu hwaro, "inonzi exoskeleton inowedzera, ichiita kuti isanyanya kusvikirwa nekubatanidza mishonga inopisa."

Sezvo zvipembenene zviri pachitamba chechikwereti pakupedzisira kwezhizha, zvino, iyo ndiyo nguva yakanakisisa yokuputira (chinangwa chaSeptember). Kana uchida kuedza mishonga inopisa, edza nemafuta .
