Шаблон:Short description Шаблон:Taxobox

Epitrimerus trilobus is a gall mite in the family Eriophyidae, found in Europe. The mites feed on the leaves of elder (Sambucus species), causing abnormal plant growths known as galls. The mite was described by the Austrian zoologist, Alfred Nalepa in 1891.

Description of the gall

Epitrimerus trilobus makes upward rolls on the leaves of elder or elderberry. The rolls can be Шаблон:Convert wide, loose or tight and can cover the whole of the leaf. Alternatively young leaves can be severely crumpled, failing to open properly.[1][2] Species of elder galled include, American black elderberry (Sambucus canadensis), European elder (Sambucus nigra), red elderberry (Sambucus racemosa).[3] Galls on dwarf elder (Sambucus ebulus) may be caused by an undetermined Epitrimerus species.[2]

The mites feed on the leaves, the surface of the leaf decreases and photosynthesis is reduced, which can result in premature leaf fall. Young and small trees under heavy attack can die. The elder aphid (Aphis sambuci) causes similar injury.[4] The mites leave the galls in late summer and spend the winter in bark crevices or buds.[2]

Distribution

Epitrimerus trilobus is found in Europe and California, USA.[5][6]
