The corn earworm – a tiny terror disguised as a caterpillar – is a major headache for corn farmers worldwide. This voracious pest, with its distinctive brown and black stripes, wreaks havoc on developing corn ears, tunneling through kernels and leaving behind a trail of destruction. Starting as tiny eggs laid on silks, the larvae—also known as "earworms"—then hatch and burrow into the developing corn, feasting on the succulent kernels, making the crop unmarketable. Their life cycle completes with pupation in the soil, emerging as moths to repeat the cycle. This relentless feeding habit can decimate yields and severely impact the quality of the harvest.
