Carnus

Systematic position. Carnus (Carnus) is a genus of dipteran insects belonging to the family Carnidae. These flies are specialized ectoparasites commonly found in bird nests, but under specific conditions, their presence is linked to the decay of plant residues or organic substrates near poultry farms and agricultural ecosystems.

Crops and harm. Although the genus Carnus is primarily associated with parasitism on birds, their mass development can negatively affect the microclimate of farming areas. They can damage organic materials, contaminate agricultural products, and facilitate the spread of pathogens, which indirectly reduces the quality of agricultural raw materials stored under improper conditions.

Biology and life cycle. The life cycle of these insects is closely linked to their hosts or organic substrates. Larvae develop in an organic-rich environment, undergoing several growth stages. Optimal conditions for rapid reproduction are high humidity and the presence of decomposing matter, making them indicators of the sanitary state of production sites.

Damage patterns. The pest causes damage by feeding on decay products and forming secondary infestation sites. In fields and storage facilities, their presence often remains unnoticed until the population reaches high densities, when flies start migrating en masse, causing discomfort and contaminating production facility surfaces.

Protection measures. Control of this species is based on strict adherence to sanitary and hygienic standards. The main recommendations include:

• Regular cleaning of areas from organic waste and bird droppings.
• Moisture control in storage rooms to prevent rotting.
• Use of specialized insecticides upon reaching threshold population levels.
• Sanitary treatment of equipment and surfaces with disinfectants.
