Dioryctria resinosella

Red pine shoot moth (Dioryctria resinosella)
Nom latin Dioryctria resinosella
Nom commun Red pine shoot moth
Biologie

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.

Dégâts

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

Régions de distribution

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

Surveillance

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

Pièges recommandés

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