Pests
Zea mays L. subsp. mays (Maize Group)
A group of dangerous polyphagous pests from the Noctuidae family that damage maize at various stages of vegetation: from clipping seedlings to destroying reproductive organs.
In the reference 4 varieties crop Maize, where this is mentioned in the description.
The main species of cutworms and armyworms causing damage to maize crops include the cotton bollworm, corn earworm, turnip moth, rustic shoulder-knot, and setaceous hebrew character. Subterranean species, such as the turnip moth, cut off young plants at the soil surface, causing thinning of the crops. Foliage-feeding and reproductive-stage species damage leaf tissues, and at a later age, tassels, silks, and kernels in the ears.
Damage to the silks by larvae leads to impaired pollination and poor grain set in the ears. Furthermore, the wounds inflicted by pests facilitate the development of secondary infections, such as Fusarium ear rot and common smut. Resistance of cultivars to cutworms is primarily achieved through the use of transgenic Bt-hybrids expressing insecticidal proteins, as classical resistance genes have not been identified in the breeding of this crop.
