Dried fruit mite

The dried fruit mite (Carpoglyphus lactis) is a member of the order Acariformes and the family Carpoglyphidae. It is a cosmopolitan pest commonly found in warehouses and food processing facilities. This mite primarily infests dried fruits, but it also readily thrives on honey, stored grains, cheese, wine, and various plant-based products, causing significant economic losses.

The biology of Carpoglyphus lactis is defined by its rapid reproductive cycle and high sensitivity to humidity. The mite passes through several developmental stages: egg, larva, protonymph, deutonymph, and adult. Under high humidity conditions (exceeding 70%), the mite populations explode. Furthermore, the species can enter a dormant state known as a hypopus, which allows it to withstand environmental stress and disperse to new sources of food.

The damage caused by this mite is both qualitative and quantitative. Infested goods become heavily contaminated with molted skins, excrement, and dead mites, resulting in an unpleasant fermented or honey-like odor. Such products are unfit for human consumption, often leading to total inventory loss. Additionally, the presence of these mites in a work environment can cause severe respiratory and dermatological allergies in personnel.

Effective management begins with strict environmental control in storage areas. Since Carpoglyphus lactis requires moisture to survive and reproduce, keeping the relative humidity below 65% is the most critical preventative step. Maintaining a dry, clean, and well-ventilated environment prevents the mite from establishing a foothold in the storage facility.

Practical control measures include:

• Implementing rigorous sanitation to remove dust and leftover food residues.
• Monitoring stored goods regularly for signs of mite colonization.
• Using fumigation with registered pesticides in unoccupied storage structures.
• Utilizing extreme temperature treatments, such as freezing or heating, to disinfest smaller batches.
• Ensuring dry storage conditions to disrupt the mite's life cycle.
