Mouse-tailed dormouse

Systematic position. The mouse-tailed dormouse (Myomimus) belongs to the order Rodentia and the family Gliridae. While generally rare, these rodents can occasionally inhabit orchards and agro-ecosystems, where they may interact with fruit-bearing crops and cause localized damage to production.

Affected crops. The pest primarily targets pome and stone fruit trees, such as apples, pears, plums, and cherries. In some cases, they are observed feeding on vineyards and berry bushes. By consuming both the fruit and sometimes the tender bark or buds of young saplings, they can impact the health and vigor of the entire plant.

Biology and life cycle. These rodents are primarily nocturnal and crepuscular. They build nests in tree cavities, birdhouses, or dense foliage. Breeding occurs during the spring and summer months, with females typically producing one litter per season. Before the winter, they enter a period of deep hibernation, finding refuge in underground burrows or hollows within tree trunks.

Damage patterns and economic impact. The primary economic damage occurs when the dormice consume ripening fruits, leaving them vulnerable to fungal infections and rot. This results in significant yield loss and reduces the marketable quality of the produce. In rare instances of high density, they may girdle young branches by chewing the bark, causing dieback or even death of the plant.

• Remove old, hollow trees and debris that serve as nesting sites.
• Install mechanical barriers or wire mesh around the trunks of young trees.
• Use physical deterrents or netting to protect ripening fruit.
• Foster habitats for natural predators like owls and other birds of prey.
• Ensure timely harvesting and removal of fallen fruit from the orchard floor.

Control measures. Due to the conservation status of some species within the genus, control measures should be primarily preventative and non-lethal. Orchard management practices, such as maintaining cleanliness and removing potential hiding spots, are the most effective strategies. In commercial settings, barrier methods provide the best protection for fruit against rodent intrusion.
