Dioryctria yatesi

Mutuura & Munroe, 1979

Mountain Pine Coneworm, Mountain Pine Coneworm Moth

Dioryctria yatesi, commonly known as the mountain pine coneworm, is a of snout moth in the Pyralidae. It was described by Mutuura and Munroe in 1979 and is restricted to the mountains of the coastal southeastern United States and Tennessee. The larvae are specialized cone borers that feed on Pinus pungens (Table Mountain pine).

Identification

are small snout moths, typical of the Dioryctria, with enlarged labial palps projecting forward like a snout. -level identification requires examination of genitalia or other microscopic characters. The restricted geographic range in the southern Appalachian Mountains helps distinguish it from other North American Dioryctria species.

Habitat

Montane forests in the southeastern United States, specifically associated with stands of Pinus pungens (Table Mountain pine).

Distribution

Mountains of the coastal southeastern United States and Tennessee. The range is restricted to the southern Appalachian Mountains.

Diet

Larvae feed on Pinus pungens (Table Mountain pine), boring into the cones of this plant.

Host Associations

Pinus pungens - larval food plantTable Mountain pine; larvae bore into cones

Behavior

Larvae bore into the cones of their pine, concealed within this structure for feeding and development. This makes them difficult to target with .

Ecological Role

As a cone borer, the likely affects seed production of its pine. It serves as host for in the Baryscapus, though specific records for D. yatesi are not documented.

Human Relevance

The specialized association with Pinus pungens and restricted range suggest limited economic impact. Related Dioryctria are significant forestry pests, and research on coneworms may inform management approaches.

More Details

Taxonomic note

The Dioryctria is classified in the Phycitinae of Pyralidae. Some authorities have placed the genus in the Pyralidae sensu stricto, while others recognize a more narrowly defined Pyralidae with Dioryctria in Crambidae. The Catalogue of Life and NCBI currently place it in Pyralidae.

Research context

While D. yatesi itself has received limited study, the Dioryctria has been the focus of research. The Baryscapus dioryctriae was described from China in 2016 as a potential biological control agent for D. pryeri and D. abietella, demonstrating the ecological and economic significance of coneworm moths.
