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...

ISPM No. 15 and the Incidence of Wood Pests: Recent Findings, Policy Changes, and Current Knowledge Gaps
2011 - IRG/WP 11-30568
Largely as a result of international trade, hundreds of species of bark- and wood-infesting insects have become established in countries outside their native range. Many of these exotic insects have caused severe economic and environmental impact to urban and forest trees in the receiving countries. Most bark- and wood-infesting insects have been transported to new countries by means of the wood...
