Pen-tailed treeshrews
The family Ptilocercidae, commonly known as pen-tailed treeshrews, belongs to the order Scandentia. These small mammals are distinct due to their unique, feather-like tail structure. While they primarily inhabit natural forest ecosystems, they can occasionally emerge as pests in plantation environments where agricultural monocultures overlap with their native range.

The primary concern regarding these animals involves oil palm plantations. They consume nectar and sap from the inflorescences of various palms. During their feeding activity, they can damage developing fruit clusters and flowers, which may lead to reduced yields if the local population density is significantly high in the plantation area.
Regarding their biology and life cycle, these animals are strictly nocturnal and highly energetic. Their diet consists largely of sugar-rich resources, which draws them to plantation crops. They exhibit a slow reproductive rate compared to rodents, meaning that their presence in fields is often more about established territorial behavior than explosive population outbreaks.
The nature of the damage is characterized by gnawing and wounding of delicate plant parts, such as young buds and developing fruits. This physical trauma not only impacts crop development directly but also provides entry points for various pathogens and secondary fungal infections that can compromise the health of the plant tissue.
Effective protection measures focus on physical exclusion and habitat management. Installing protective collars or barriers on the trunks of palms can prevent these animals from reaching the upper canopy where the flowers and fruits are located. Additionally, maintaining natural corridors outside the plantation area can discourage them from frequenting the crops in search of food.
