Hairy dried fruit beetle

Systematic position: Carpophilus pilosellus belongs to the order Coleoptera, family Nitidulidae. These insects are known as secondary pests, often associated with decaying plant material, but capable of causing significant damage when healthy fruit integrity is compromised.

Host crops: This species is particularly dangerous for a wide range of agricultural products. It primarily affects stone and pome fruits in orchards, and also infests produce during storage and transportation. It is frequently found on vegetable crops, especially during ripening periods when high humidity and skin punctures are present.

Biology and life cycle: The life cycle of the beetle is closely linked to the availability of sugar-rich food sources. Females lay eggs in cracks or directly into plant tissue undergoing fermentation. Larvae develop rapidly, feeding on the pulp, which accelerates spoilage and decay. Optimal conditions for reproduction include high temperatures and high humidity.

Nature of damage: The primary damage involves beetles and larvae creating galleries inside the fruit, contaminating it with frass, and facilitating the growth of pathogenic microorganisms, including mold fungi. This leads to a loss of marketability, rot, and the impossibility of long-term storage. Affected areas darken and soften quickly.

Control measures: Controlling Carpophilus pilosellus requires an integrated approach. It is essential to follow sanitary practices: removing fallen fruit and plant debris from the field, as these serve as reservoirs for the pest. During storage, maintaining low temperatures is crucial to slow down larval development. Insecticide application is effective during peak flight periods, but chemical control must be strictly regulated prior to harvest.
