Coneworms; Dioryctria moths (Dioryctria spp.) is an insect pest.

The larvae of this genus feed internally on coniferous trees, attacking regions with rapid growth such as cones and stems, although several species feed externally on foliage and buds. Damage often leads to substantial economic loss, particularly in tree farms, plantations, shelterbelts, and seed orchards.
