Dioryctria resinosella

Red pine shoot moth (Dioryctria resinosella)
Latin Name Dioryctria resinosella
Common Name Red pine shoot moth
Biology

A snout moth (Pyralidae) associated with conifers. Larvae develop in resin ducts of pine trees, with 1-2 generations/year. Pupation occurs in resinous galleries. Adults are attracted to pine volatiles.

Damage

Larval feeding damages resin ducts, reducing resin production and weakening tree defense. Causes dieback in young pines; may facilitate secondary pathogen

Distribution Regions

Found in pine-dominated regions: Europe, North America, and parts of Asia (where Pinus species are native).

Monitoring

Pheromone traps targeting adults; inspection of resinous exudates and larval galleries on pine stems.

Recommended Traps

Funnel traps or sticky panel traps baited with D. resinosella sex pheromone lures.

Literature review

Semiochemical evidence

The cited publications support the exact compound-species relationship. Formulation, ratio, loading, release rate and field lifetime depend on a validated lure protocol and are not inferred here.
