Spruce spider mite zvakakosha zvipembenene zveMichigan Kisimusi miti.Kuderedza kushandiswa kwemishonga yezvipembenene kunogona kubatsira varimi kuchengetedza nyuchi dzinodya dzinobatsira, nokudaro zvichibatsira kudzora tumbuyu rinokosha.
MuMichigan, spruce spider mite (Oligonuchus umunguis) ipembenene yakakosha yemiti yeconiferous.Kapembenene aka kanopinda miti yese yeKisimusi inotengeswa uye inowanzokonzera kurasikirwa kukuru kwemari mukurimwa kwespruce neFraser fir.Muminda inochengetedzwa pachivanhu, huwandu hwezvipembenene hudiki nekuda kwekushandisa mishonga yekuuraya zvipembenene, saka dandemutande rinowanzova tupukanana.Mhuka dzinodyiwa dzinobatsira varimi nekuti dzinodya tumbuyu uye dzinobatsira kudzora huwandu hwevanhu.Pasina ivo, iyo spruce spider mite huwandu huchaputika kamwe kamwe, zvichikonzera kukanganisa kumiti.
Sezvo chirimo chasvika, varimi vanofanira kunge vakagadzirira kuwedzera zvirongwa zvavo zvekuvhima mite.Kuti vaone spider mite, varimi vanofanira kuenzanisa miti yakawanda mumunda wega wega uye iva nechokwadi chekusarudza miti kubva munzvimbo dzakasiyana-siyana uye mitsara mukati nekunze.Zvikamu zvakakura zvemuti zvichawedzera huchokwadi hwevarimi pavanenge vachiongorora huwandu hwevanhu uye njodzi dzinogona kuitika.Kuongorora kunofanirwa kuitwa mumwaka wese, kwete chete mushure mekunge zviratidzo zvaonekwa, nekuti kazhinji kunonoka kurapwa kunoshanda.Nzira iri nyore yekuona mite yevakuru uye vechidiki ndeyekuzunungusa kana kurova matavi pa scout board kana pepa (mufananidzo 1).

Zviratidzo zvekukuvadzwa kwespruce spider mite zvinosanganisira chlorosis, tsono dzetsono uye kubuda kwemavara uye kunyange mashizha ebrown mashizha, anogona kupedzisira apararira kumuti wese.Paunenge uchitarisa kukuvara kuburikidza negirazi reruoko, zviratidzo zvinoratidzika sediki yero yakatenderedza nzvimbo yakatenderedza nzvimbo yekudyisa (mufananidzo 3).Kuburikidza nekutarisisa kutarisisa, kudzora kurwisa uye kushandiswa kwemishonga yezvipembenene isinganyanye kukuvadza kune dzinongodya nyama mite, spruce spider mite inogona kudzivirirwa kubva kuparadzwa.Nzira iri nyore yekuona zvinodiwa nemanejimendi ndeyekuongorora kana kuferefetwa kunoratidza kuti huwandu hwevanhu huri kukura kana kuti huri pamwero wekuparadza.Zvakakosha kuyeuka kuti spruce spider mite population inoshanduka nokukurumidza, saka kungotarisa kukanganisa kwemuti hakurevi nemazvo kana kurapwa kuchidiwa, nokuti vanhu vakafa kubva ipapo vanogona kunge vakakonzera kukanganisa, saka kupfapfaidza hakuna maturo. .
