Cathartus

Cathartus is a genus of beetles belonging to the family Silvanidae (order Coleoptera). These small insects are recognized as significant pests in agricultural settings, specifically targeting stored grain, legumes, and various flour-based products within granaries, elevators, and processing facilities.

The primary crops affected by Cathartus include various cereal grains, seeds, and processed food products. They thrive in environments where moisture content is high, often appearing in grain masses that have begun to deteriorate or have developed fungal growth, which makes the substrate more accessible for their larvae.

The biology and life cycle of the beetle are highly dependent on environmental conditions, particularly temperature and humidity. Female beetles deposit their eggs directly onto the surface of grain or within existing cracks. The larvae develop by feeding internally on the grain, eventually causing significant damage to the seed's integrity.

The economic impact of Cathartus is characterized by weight loss in stored commodities and a reduction in germination rates. Beyond direct consumption, their infestation leads to the contamination of grain with excrement, larval skins, and webbing, which lowers the overall quality and commercial value of the affected batches.

Effective management and protection strategies include:

• Maintaining rigorous sanitation standards within storage facilities.
• Controlling the moisture content and temperature of stored grain to inhibit development.
• Applying professional fumigation when heavy infestations are detected.
• Utilizing pheromone traps for early detection and population monitoring.
• Ensuring proper aeration to prevent grain heating and moisture accumulation.
