Eudociminus mannerheimii

Boheman, 1836

Cypress Weevil

Eudociminus mannerheimii, the cypress , is a North in the . It breeds primarily in scarred, weakened, or fallen cypress trees and occasionally damages nursery stock and stump sprouts. Despite its potential to cause localized tree mortality, published biological information remains extremely limited.

Habitat

Cypress swamps and wetland forests. Breeding occurs in scarred, weakened, or fallen bald cypress and pond cypress. Also documented in nursery settings with small diameter cypress stock.

Distribution

to North America. Documented in Florida with range expansion noted; referenced in North Carolina.

Host Associations

Taxodium distichum - breeding bald cypress; scarred, weakened, or fallen trees used for breeding; small diameter nursery stock damaged by larval tunneling
Taxodium ascendens - breeding pond cypress; scarred, weakened, or fallen trees used for breeding; stump sprouts and planted seedlings damaged by feeding

Behavior

feeding causes limited wounding and girdling of pond cypress stump sprouts and planted seedlings. tunnel through the main stem and root collar of small diameter bald cypress nursery stock.

Ecological Role

Possible causative agent of tree mortality in weakened or stressed cypress. Functions as a of damaged cypress wood.

Human Relevance

Occasional pest of cypress nursery operations and planted seedlings. Not a frequent pest of major economic importance, but damage warrants recognition in forestry and restoration contexts.

More Details

Research needs

The lack of information regarding its complete biology, potential alternative , and management options has been explicitly identified as warranting further research (Mayfield 2005).

Taxonomic note

Placed in Molytinae; historically treated among (Pissodini or related groups) but now classified in Eudociminus.
