Skadedyrsordbog – Green Guardia

Bladlus: Genkend og bekæmpe et angreb naturligt

Bladlus er blandt de mest almindelige planteskadedyr i haver, på altaner og hos stueplanter. De suger plantesaft, svækker væksten og kan overføre sygdomme. Angreb kan effektivt bekæmpes med de rigtige gavnlige insekter.

ⓘAphidoidea · Bladlus #Honningdug · Myrer · Bladkrølling

Hvad er bladlus?

Bladlus er små, oftest grønne, sorte eller gullige insekter, der slår sig ned i kolonier på unge skud, undersiden af blade og knopper. De formerer sig meget hurtigt – ofte uden gødskning – og kan svække planter alvorligt inden for kort tid.

Sugende skadedyr hurtig reproduktion Honningdug

Typiske tegn på bladlusangreb

  • krøllede, deformerede eller klæbrige blade
  • synlige bladluskolonier på skudspidserne
  • Honningdug på blade eller underliggende overflader
  • Myrer på planten (de "plejer" bladlus)
  • svækket vækst
Green Guardia-tip: Myrer er et tydeligt advarselstegn. Hvor der er mange myrer, er bladlus normalt ikke langt væk.

Hvilke planter bliver ofte påvirket?

  • Grøntsagsplanter (f.eks. peberfrugter, tomater, bønner)
  • Frugttræer og bærbuske
  • Prydplanter og roser
  • Balkon og stueplanter

Hvorfor opstår bladlus?

  • bløde, nitrogenrige skud
  • varmt, tørt vejr
  • få naturlige modstandere
  • Myrer fremmer bladluskolonier

Egnede gavnlige insekter mod bladlus

Mariehøns og mariehønelarver

  • spiser store mængder bladlus
  • især effektiv i larvestadiet
  • ideel til have og altan

Florfliegenlarven

  • også kaldet "bladlusløver"
  • meget glubsk og alsidig
  • Effektiv selv i tilfælde af alvorlig angreb

Parasitiske hvepse (Aphidius-arter)

  • bladlus parasiterer hinanden målrettet
  • ideel til drivhuse og stueplanter
  • have en varig indflydelse på den grundlæggende årsag
Hvorfor gavnlige insekter er det bedste valg: Bladlus sidder åbent på planten og er let tilgængelige for deres naturlige fjender. Nyttige insekter regulerer angrebet uden at skade planterne eller miljøet.

Yderligere naturlige foranstaltninger

  • Skyl planterne med vand (i tilfælde af let angreb)
  • Hold myrer væk (limringe, barrierer)
  • Gød efter placering (ikke for højt nitrogenindhold)

Ofte stillede spørgsmål om bladlus

Er bladlus farlige for planter?

Ja, i tilfælde af alvorlig angreb svækker de planterne betydeligt og kan overføre sygdomme.

Hvor hurtigt formerer bladlus sig?

Meget hurtigt – under gunstige forhold skabes nye generationer inden for få dage.

Hvornår er gavnlige insekter nyttige?

Behandl så tidligt som muligt i angrebet, før der dannes store kolonier.

Hvorfor bliver bladlus ved med at komme tilbage?

Ofte forårsaget af myreaktivitet eller en ubalance i den naturlige population af gavnlige insekter.

Hurtigt overblik

  • Skadedyr: Bladlus
  • Areal: Blade og skud
