Definice a Význam "armyworm"

What is an "armyworm"?

Armyworm refers to the larval stage of certain moth species, including Spodoptera frugiperda and Mythimna unipuncta. These pests are named "armyworms" due to their behavior of moving in large groups, resembling an advancing army. Armyworms are destructive agricultural pests that feed on a wide range of crops, including corn, wheat, rice, and grasses. They have voracious appetites and can cause significant damage to crops by defoliating plants and consuming leaves, stems, and even developing seeds. The larvae are typically green or brown in color, with distinctive stripes along their bodies.
