Aculus xylostei

Gall mite Aculus xylostei

Description

Aculus xylostei is a species of eriophyid mite that primarily infests plants from the genus Lonicera (honeysuckles). This tiny mite feeds by sucking sap from the leaves, causing distinctive symptoms on the host plant. One of the most noticeable effects of an infestation by Aculus xylostei is the distortion of the leaves. The borders of the leaves become wavy and curl in irregular patterns due to the mites' feeding. These symptoms are a result of the mites' activity, as they feed on the cells in the leaf tissue, disrupting normal growth and causing the characteristic curling. Though Aculus xylostei is very small and difficult to detect with the naked eye, the damage it causes to the plant is quite visible. In severe infestations, the leaves may not only curl but also become stunted or deformed, reducing the plant’s overall health and aesthetic appeal. Control of Aculus xylostei usually involves monitoring for early signs of damage and using acaricides or biological controls to reduce mite populations. Since eriophyid mites can reproduce quickly, timely intervention is important to prevent extensive damage to honeysuckle plants. Regular pruning and removal of affected leaves may also help in reducing the spread of the mites.
