Bostrichus aterHylastes angusticollisHylastes pinicolaHylesinus chloropusIpsocossonus anomalusTomicus pinicola Hylastes ater is a species of beetle in the family Curculionidae, the true weevils.

The whitish egg is less than one millimeter long, and the larva is c-shaped, legless, and white with an amber-colored head capsule.

[1] Other recorded host trees include silver fir (Abies alba), colonial pine (Araucaria cunninghamii), Port Orford cedar (Chamaecyparis lawsoniana), common larch (Larix decidua), Sitka spruce (Picea sitchensis), Douglas-fir (Pseudotsuga menziesii), and coast redwood (Sequoia sempervirens).

The female bores an egg gallery up to 13 centimeters in length along the surface of the wood, often parallel to the grain.

[4] During some parts of the year it may face competition from the red-haired bark beetle (Hylurgus ligniperda), which also reproduces in Monterey pines.

[5] Damage to the trees is increased when the beetle acts as a vector for sapstain fungi, introducing them into the wounds.

As mature trees are continually harvested for wood, the many stumps left behind are infested by the beetle, which then spreads to the seedlings.

[3] While the beetle has been known to cause high levels of mortality in crops of seedlings in Chile and Australia,[8] it does not kill many trees in New Zealand.

Shipments of logs are fumigated with phosphine, which is a very effective alternative for the ozone-depleting compound methyl bromide.
