Punteruolo del melo: riconoscere i danni ai fiori e prevenirli in modo naturale

L'oziorrinco dei fiori di melo è un piccolo insetto che può causare gravi danni ai meli in primavera. Le larve distruggono i fiori dall'interno, impedendo lo sviluppo dei frutti. La diagnosi precoce e misure di controllo naturali mirate sono fondamentali.

ⓘAnthonomus pomorum · incisore di fiori di melo #Teste marroni · Danni ai fiori · Perdita del raccolto

Cos'è il punteruolo del melo?

Il punteruolo del fiore del melo (Anthonomus pomorumLo *Pseudomus aureus* è un piccolo tonchio brunastro. Sverna come adulto e diventa attivo molto presto durante l'anno. Le femmine depongono le uova nei boccioli dei fiori chiusi. La larva poi mangia le parti del fiore – il bocciolo non si apre mai.

Curculionidi Parassita dei fiori Possibile fallimento del raccolto
Importante: I danni si verificano molto presto nel corso dell'anno, spesso prima che ce ne accorgiamo. Chi interviene solo quando le piante sono in fiore, di solito è già troppo tardi.

Come riconoscere un'infestazione

  • boccioli di fiori marroni e appassiti ("teste marroni")
  • I fiori non si aprono.
  • piccolo foro di puntura sul germoglio
  • Meno fiori → minore allegagione
Suggerimento della Guardia Verde: Controllare i meli molto presto in primavera (a partire dal rigonfiamento delle gemme), soprattutto in luoghi soleggiati e riparati.

Quali piante sono colpite?

  • Apple (host principale)
  • raro melo selvatico

Perché si verifica l'infestazione?

  • inverni miti (alto tasso di sopravvivenza degli scarabei)
  • mancanza di avversari naturali
  • siti di svernamento indisturbati (foglie, corteccia)

Misure naturali e insetti utili adatti

1. Misure meccaniche (molto precoci!)

  • Scuotere delicatamente gli alberi al mattino, quando le temperature sono fresche.
  • Raccogli gli scarabei da un panno/telone

Raccomandazione di organismi benefici: Nematodi contro i coleotteri svernanti

Nematodi (ad esempio specie Steinernema) Possono essere utilizzati in modo mirato per ridurre gli stadi invernali dei coleotteri nel terreno.

  • Perché è una buona scelta: incontra gli scarabei prima che entrino nelle gemme per deporre le uova
  • Perché è utile: riduce precocemente la pressione dell'infestazione
  • Importante: Sono necessari un terreno umido e una temperatura del terreno adeguata.

Promuovere antagonisti naturali

  • uccelli (ad esempio le cince) mangiano gli scarabei svernanti
  • coleotteri terrestri caccia a terra
Perché è fondamentale agire tempestivamente: Il tonchio del melo danneggia direttamente il fiore: una volta distrutto, non è più possibile ripararlo. In questo caso, prevenire è più importante che "riparare".

FAQ sul punteruolo del melo

Quanti fiori possono essere distrutti?

Una singola femmina può danneggiare diverse decine di gemme. In caso di grave infestazione, sono possibili perdite significative del raccolto.

Perché non vedo coleotteri, ma molti testabruna?

Gli scarabei sono attivi molto presto durante l'anno e spesso restano ben nascosti durante il giorno. I danni rimangono visibili anche dopo la loro scomparsa.

Qual è il momento migliore per agire?

Molto presto in primavera, a partire dal rigonfiamento delle gemme, ancora prima della fioritura.

L'albero può riprendersi?

In parte sì, ma i fiori gravemente danneggiati mancano definitivamente e la resa diminuisce di conseguenza.

Panoramica rapida

  • Parassita: Punteruolo del fiore di melo
  • Zona: boccioli di fiori
  • Segnali: Brune, mancanza di fioritura
  • Misure: Monitoraggio precoce · Nematodi · Raccolta manuale
✓ Intervenire tempestivamente

Segni tipici

  • gemme marroni
  • I fiori non si aprono.
  • bassa allegagione
  • gravi danni in primavera
