Seed bugs

The range of host crops is extremely wide. Seed bugs attack cereal grains including wheat and barley, vegetables, legumes, as well as ornamental plants and fruit trees. Species that specialize in sucking sap from developing seeds and young shoots during peak growth periods pose the most significant threat to harvest yields.

The biology of these pests is characterized by incomplete metamorphosis. Females lay eggs in the soil or on vegetative parts of plants. Adults usually overwinter in crop residues, under bark, or within the upper layer of soil. Depending on the local climate, they may complete one or more generations per growing season.

The damage caused involves plant weakening due to sap extraction. During mass outbreaks, this leads to leaf chlorosis, stem deformation, and significantly reduced seed germination and quality. Bug feeding wounds can also facilitate the entry of secondary pathogens, as puncture sites serve as entry points for various fungi and bacteria.

• Cultural control: Removal of alternate weed hosts.
• Mechanical control: Deep autumn plowing to destroy overwintering sites.
• Chemical control: Targeted application of pyrethroid or organophosphate insecticides when thresholds are exceeded.

Effective management requires an integrated approach. Prevention involves strict field hygiene to reduce habitat availability. Monitoring populations through field scouting is essential to determine the correct timing for interventions, ensuring the protection of crops while minimizing unnecessary chemical usage.
