Ungawasusa kanjani ama-psyllids (ama-psyllids)

Kunezinhlobo ezingaphezu kuka-100 zamapheshana atholakala kulo lonke elaseNyakatho Melika. Nansi indlela yokuzibona futhi uziqede usebenzisa izindlela zokwelapha ezifakazelwe, zemvelo kanye nezakhiwe.

Izintwala zamaqabunga, ngezinye izikhathi ezibizwa ngokuthi i-jumping plant lice, zidla izitshalo ezihlukahlukene, kuhlanganise nezihlahla eziningi zezithelo nezithelo ezincane, kanye notamatisi namazambane. Kokubili abadala kanye nama-nymphs badla ngokubhoboza ingaphezulu leqabunga nokukhipha ubisi lwamaseli. Lokhu kubangela ukuthi amahlamvu (ikakhulukazi angaphezulu) abephuzi, agoqe, futhi ekugcineni afe. I-honeydew ekhishwe emaqabunga ikhuthaza ukukhula kwesikhunta esimnyama, esine-sooty. Izinhlobo eziningi zithwala amagciwane asakaza izifo.

Ukuhlonza

Abadala (1/10 intshi ubude) anombala obomvu ngokunsundu, anamaphiko asobala nemilenze egxumagxumayo enamandla. Zisebenza kakhulu futhi zizogxuma noma zindiza zihambe uma ziphazanyiswa. Ama-nymphs ayisicaba futhi amise okwe-elliptical, acishe abe nama-scaly. Azikhuthele uma kuqhathaniswa nabantu abadala futhi ziningi kakhulu ngaphansi kwamaqabunga. Ama-nymphs asanda kuchanyuselwa anombala ophuzi, kodwa aphenduka abe luhlaza njengoba ekhula.

Qaphela: Amahlamvu amaqabunga ayi-monophagous, okusho ukuthi akhethekile (uhlobo ngalunye ludla uhlobo olulodwa lwesitshalo).

Umjikelezo wokuphila

Abantu abadala overwinter emifantwini yeziqu zezihlahla. Ekuqaleni kwentwasahlobo ziyakhwelana futhi ezinsikazi ziqala ukubeka amaqanda aphuzi ngokusawolintshi emifantwini ezungeze imiqumbe nasemaqabungeni lapho amahlamvu evuleka. Ukuchanyuselwa kwenzeka ngemva kwezinsuku ezingu-4-15. Ama-nymphs aphuzi-aluhlaza angena kuma-instars amahlanu emasontweni angu-2-3 ngaphambi kokuba afinyelele esigabeni sabantu abadala. Ngokuya ngezinhlobo, kukhona isizukulwane esisodwa kuya kwezinhlanu ngonyaka.

Indlela yokulawula

1. Fafaza uwoyela we-horticultural ekuqaleni kwentwasahlobo ukuze ubulale abantu abadala namaqanda asebusika.
2. Izinambuzane ezizuzisayo ezifana nama-ladybugs nama-lacewings ziyizilwane ezibalulekile ezidla lezi zinambuzane. Ukuze uthole imiphumela ehamba phambili, khulula uma amazinga ezinambuzane ephansi ukuya kokulinganisela.
3. Uma isibalo sabantu siphezulu, sebenzisa isibulala-zinambuzane semvelo esingenabuthi obuncane nesikhashana ukuze ulawule, bese ukhulula izinambuzane ezidla ezinye ukuze ugcine ukulawula.
4. Umhlaba we-Diatomaceous awuqukethe ubuthi obunobuthi futhi usebenza ngokushesha lapho uthintana. Fafaza izitshalo zemifino kancane futhi ngokulinganayo nomaphi lapho abantu abadala bekhona.
5. Insipho ye-Safer® ebulala izinambuzane isebenza ngokushesha ekuthelelekeni okunzima. Isibulala-zinambuzane semvelo esinesikhathi esifushane sokusebenza, sisebenza ngokulimaza ungqimba lwangaphandle lwezinambuzane ezinomzimba othambile, okubangela ukuphelelwa amanzi emzimbeni nokufa emahoreni ambalwa. Uma izinambuzane zikhona, sebenzisa u-2.5 oz/gallon wamanzi, phinda njalo ezinsukwini ezingu-7-10 njengoba kudingeka.
6. I-WP Ezungezile (ubumba lwe-kaolin) yakha ifilimu yokuvimbela evikelayo esebenza njengesivikelo sesitshalo esibanzi ukuze kuvinjelwe ukulimala ezinambuzaneni.
7. I-BotaniGard ES iyisibulala-zinambuzane esisebenza kahle kakhulu sezinto eziphilayo esiqukethe Boveria Basiana, isikhunta se-entomopathogenic esithinta uhlu olude lwezinambuzane zezitshalo, ngisho nezinhlobo ezimelana nazo! Ukusetshenziswa kwamasonto onke kungavimbela ukuqhuma kwezinambuzane futhi kunikeze isivikelo esilingana noma esingcono kunezibulala-zinambuzane ezivamile zamakhemikhali.
8. I-70% yamafutha e-neem agunyazwe ukusetshenziswa kwemvelo futhi angafuthwa emifino, ezihlahleni zezithelo nezimbali ukubulala amaqanda, izibungu kanye nezinambuzane ezindala. Xuba u-1 oz/gallon wamanzi bese ufafaza zonke izindawo zamaqabunga (kuhlanganise nangaphansi kwamaqabunga) zize zibe manzi ngokuphelele.
9. Uma amazinga ezinambuzane engabekezeleleki, phatha izindawo njalo ezinsukwini ezi-5 kuya kweziyi-7 ngesibulala-zinambuzane esigunyazwe ukusetshenziswa kwemvelo. Ukulawula okuphumelelayo kudinga ukumbozwa okuphelele kokubili phezulu nangaphansi kwamaqabunga ahlaselwe.

Ithiphu: Ungavundisi kakhulu - izinambuzane ezimunca njengezitshalo ezinamazinga aphezulu e-nitrogen kanye nokukhula okusha okuthambile.
