Susceptibility of Sarawak timber to attack by powder post beetles
2001 - IRG/WP 01-10413
Degradation of timber by powder post beetles results in some economic loss to the timber merchants and end-users alike. The infestation is normally confined to the sapwood of some hardwoods due to the presence of starch that serves as food for the powder post beetles. This study was conducted to assess the susceptibility of commercial timber species of Sarawak, Malaysia to attack by powder post be...

New perspectives on the biology of the tropical powderpost beetle, Minthea rugicollis (Walk.)
1994 - IRG/WP 94-10085
Minthea rugicollis (Walk.) is one of the most important pests of seasoned hardwoods in the tropics. The species owes its ubiquity largely to its insidious development within a nutrient-filled environment and also to a strong coevolutionary specialization with its natural habitat, wood. Such an environment provides a buffer to extrinsic fluctuations and accounts for a wider range of tolerance by im...

Minthea rugicollis (Walk.) (Coleoptera: Lyctidae): A pest of rubberwood
1992 - IRG/WP 92-1570
Rubberwood (Hevea brasiliensis) has grown in prominence as a source of timber in recent years. One of the drawbacks in the utilization of this species is its susceptibility to attack by powder-post beetles belonging to the family Lyctidae. In Malaysia, Minthea rugicollis (Walk) is the, most commonly found species attacking seasoned rubberwood. In this paper, information available thus far on Minth...

Lyctine susceptibility testing and dealing with rarely susceptible hardwood species
2007 - IRG/WP 07-10607
This study examined the lyctine susceptibility of 16 timber species or hybrids. Several of the timbers have been placed previously in a ‘rarely susceptible’ category, but for standards and compliance purposes, such in-between ratings are not acceptable. Timber specimens were spot tested for starch content, and exposed to three species of lyctine beetles in an insectary. New criteria were devel...
