Szkodnik kukurydziany: rozpoznawanie i naturalne zapobieganie szkodom wyrządzanym przez żerowanie na kukurydzy

Omacnica prosowianka to motyl, którego gąsienice uszkadzają przede wszystkim rośliny kukurydzy. Wgryzają się w łodygi i kłosy, osłabiając rośliny i powodując dalsze uszkodzenia. Tutaj dowiesz się, jak rozpoznać omacnicę prosowiankę i jak zapobiegać jej naturalnymi metodami.

ⓘOstrinia nubilalis #Gąsienice stonki kukurydzianej · Drążące chodniki w łodydze

Czym jest stoneczka kukurydziana?

Omacnica kukurydziana to ćma. Dorosłe osobniki są niepozorne, ale larwy stanowią problem. gąsienicePo wykluciu się larwy zagrzebują się w łodygach, kątach liści i kolbach, gdzie żyją chronione wewnątrz rośliny.

Gąsienice w łodydze motyl kilka etapów rozwoju
Ogłoszenie: Uszkodzenia często wykrywane są późno, ponieważ gąsienice żyją wewnątrz rośliny. Dlatego wczesna obserwacja lotu motyli jest szczególnie ważna.

Jak rozpoznać inwazję

  • Otwory wiertnicze i galerie zasilające w łodygach kukurydzy
  • rośliny, które się wyginają lub łamią
  • Ślady żerowania na pachwinach liści lub tłokach
  • Biało-żółte gąsienice wewnątrz rośliny
Wskazówka Green Guardia: Sprawdzaj rośliny regularnie w trakcie głównego sezonu lotów, aby wykryć jaja lub wczesne oznaki żerowania.

Które rośliny są dotknięte?

  • Kukurydza cukrowa i paszowa
  • częściowo także proso i inne trawy

Dlaczego dochodzi do zarażenia?

  • Lot motyla w ciepłą, letnią pogodę
  • brak naturalnych przeciwników
  • resztki pożniwne (zimujące)
  • gęste zarośla z małą cyrkulacją powietrza

Co robić w przypadku zarażenia? (naturalne i rozsądne)

1. Profilaktyka w grządce ogrodowej

  • Regularnie sprawdzaj rośliny
  • Usuń ściernisko kukurydzy po zbiorach
  • Płodozmian

2. Środki mechaniczne

  • Usuń silnie zainfekowane części roślin
  • Nie pozostawiaj resztek roślin na rabacie kwiatowej.

Zalecane owady pożyteczne: osy pasożytnicze (Trichogramma)

Osy pasożytnicze z rodzaju Trichogramma To sprawdzeni naturalni wrogowie stoneczki kukurydzianej. Pasożytują na jajach motyla, uniemożliwiając wylęg gąsienic. Te pożyteczne owady są maleńkie, nieszkodliwe dla ludzi i znikają same, gdy nie ma już w nich jaj.

Dlaczego osy pasożytnicze są pożyteczne: Największą dźwignią jest jajo. Pasożytnicze osy atakują właśnie ten obszar i pomagają ograniczyć presję inwazji na wczesnym etapie.

FAQ na temat stoneczki kukurydzianej

Kiedy istnieje największe zagrożenie dla kukurydzy?

W sezonie lotów motyli latem. W tej fazie składane są jaja, z których później wykluwają się szkodliwe gąsienice.

Dlaczego rośliny kukurydzy się pochylają?

Roślina traci stabilność z powodu tworzenia się tuneli odżywczych w łodydze i może złamać się na wietrze lub deszczu.

Czy same osy pasożytnicze wystarczą?

Są bardzo dobrym uzupełnieniem. Optymalnym podejściem jest połączenie profilaktyki, higieny roślin i wykorzystania pożytecznych owadów.

Jakie są najważniejsze środki zapobiegawcze?

Po zbiorach usuń resztki roślinne i zaplanuj wykorzystanie pożytecznych owadów we właściwym czasie.

Szybki przegląd

  • Szkodnik: stonkę kukurydzianą
  • Obszar: Ogród, pole kukurydzy
  • Znaki: Otwory wiertnicze, uszkodzone rośliny
  • Owad pożyteczny: Osy pasożytnicze (Trichogramma)
✓ Zaprzestań spożywania jajek na wczesnym etapie

Typowe objawy

  • Lot motyli latem
  • Uszkodzenie wewnątrz łodygi
  • widoczność późnych uszkodzeń
