Piralide europea del mais: riconoscere e prevenire naturalmente i danni da alimentazione sul mais

La piralide del mais è una falena i cui bruchi danneggiano principalmente le piante di mais. Si insinuano nei gambi e nelle pannocchie, indebolendo le piante e causando ulteriori danni. Qui imparerai come identificare la piralide del mais e come prevenirla con metodi naturali.

ⓘOstrinia nubilalis #Bruchi della piralide del mais · Gallerie perforanti nel fusto

Cos'è la piralide del mais?

La piralide del mais è una falena. Le falene adulte sono poco appariscenti, ma le larve sono problematiche. bruchiDopo la schiusa, si insinuano nei fusti, nelle ascelle delle foglie e negli spadici, dove vivono protetti all'interno della pianta.

Bruchi nello stelo farfalla diverse fasi di sviluppo
Un avviso: Spesso i danni vengono rilevati solo tardivamente, poiché i bruchi vivono all'interno della pianta. L'osservazione precoce del volo delle falene è quindi particolarmente importante.

Come riconoscere un'infestazione

  • Fori e gallerie di alimentazione nel fusto del mais
  • piante che si piegano o si rompono
  • Segni di alimentazione sulle ascelle delle foglie o sui pistoni
  • Bruchi bianco-gialli all'interno della pianta
Suggerimento della Guardia Verde: Controllare regolarmente le piante durante la stagione principale del volo per individuare la presenza di uova o i primi segni di alimentazione.

Quali piante sono colpite?

  • Mais dolce e mais da foraggio
  • in parte anche miglio e altre erbe

Perché si verifica l'infestazione?

  • Volo di farfalla nel caldo clima estivo
  • mancanza di avversari naturali
  • residui colturali rimanenti (svernamento)
  • boschi densi con scarsa circolazione dell'aria

Cosa fare in caso di infestazione? (naturale e sensato)

1. Prevenzione nell'aiuola

  • Controllare regolarmente le piante
  • Rimuovere le stoppie di mais dopo il raccolto
  • Rotazione delle colture

2. Misure meccaniche

  • Rimuovere le parti di piante fortemente infestate
  • Non lasciare detriti vegetali sull'aiuola.

Insetti utili consigliati: Vespe parassite (Trichogramma)

Vespe parassite del genere Trichogramma Si tratta di nemici naturali comprovati della piralide del mais. Parassitano le uova della tignola, impedendo ai bruchi di schiudersi. Questi insetti benefici sono minuscoli, innocui per l'uomo e scompaiono spontaneamente quando non sono più presenti uova.

Perché le vespe parassite sono utili: La leva più efficace è rappresentata dall'uovo. Le vespe parassite prendono di mira proprio questa zona e contribuiscono a ridurre la pressione dell'infestazione in una fase iniziale.

FAQ sulla piralide del mais

Quando è il pericolo maggiore per il mais?

Durante la stagione estiva, durante la quale le farfalle volano, vengono deposte le uova, dalle quali poi si schiudono i bruchi nocivi.

Perché le piante di mais si piegano?

La pianta perde stabilità a causa dei tunnel di alimentazione nel fusto e può rompersi a causa del vento o della pioggia.

Le vespe parassite sono sufficienti da sole?

Sono un'ottima aggiunta. L'approccio ottimale è una combinazione di prevenzione, igiene delle piante e utilizzo di insetti utili.

Qual è la misura preventiva più importante?

Dopo la raccolta, rimuovere i residui vegetali e pianificare l'impiego di insetti utili al momento opportuno.

Panoramica rapida

  • Parassita: piralide europea del mais
  • Zona: Giardino, campo di grano
  • Segnali: Fori, piante rotte
  • Insetto utile: Vespe parassite (Trichogramma)
✓ Interrompere precocemente l'assunzione di uova

Segni tipici

  • Volo di farfalla in estate
  • Danni all'interno dello stelo
  • visibilità dei danni tardivi
  • Svernamento nei resti vegetali
