Aspects of the biology of the wood-boring weevil Pselactus spadix herbst
1997 - IRG/WP 97-10221
The external morphology of the adult and larval digestive tract of the wood boring weevil Pselactus spadix has been reported for the first time. An examination of adult gut ultrastructure showed that the foregut was adapted for the wood boring habit with the presence of chitinous setae, grinding plates and sieve plates. The adult midgut bore eight caecae and numerous palpii. Spherical yeast-like m...

Borates and their biological applications
1998 - IRG/WP 98-30178
This paper reviews some of the many biological applications of borates. Boron is a ubiquitous element found widely distributed in the environment and is a normal component of a healthy diet. Elemental boron does not exist in nature, but is always found combined with oxygen in compounds called borates. Boron is an essential micronutrient for plants, and there is evidence to suggest that boron is of...

Size of food resource determines brood placement in Reticulitermes flavipes (Isoptera: Rhinotermitidae)
2000 - IRG/WP 00-10351
Most species of subterranean termite house and care for larvae in specialised chambers or complex nurseries. In addition to these chambers, the genus Reticulitermes also keeps larvae at sites where foragers are feeding, a trait more commonly found in damp wood and dry wood termites. This phenomenon of holding larvae at foraging sites is quite well known among researchers who work with Reticuliterm...

Establishing standard principles for laboratory bioassays of termiticides with subterranean termites - progress, problems and prospects
1993 - IRG/WP 93-10013
Laboratory bioassays of termiticides, including wood preservatives, aim to give an indication of the likely concentrations effective in preventing damage to timber products and other materials in the field. In laboratory bioassays field conditions should be simulated as closely as possible. With a wide range of procedures in use around the world it may often be difficult to compare results between...

Laboratory bioassays with termites – The importance of termite biology
2005 - IRG/WP 05-10550
Subterranean termites are frequently used in bioassays to asses the effectiveness of insecticides or the resistance of materials. Termites which appear to be vigorous with high inherent levels of activity are often relied upon, yet at the end of the experiments survival may be very unsatisfactory, even in the favourable environment of controls. Consequently, results from such bioassays may be mean...

Observations on the morphology, ecology and biology of Xylophaga dorsalis (Turton) (Mollusca: Xylophagainae) in the Trondheimsfjord (Western Norway)
1981 - IRG/WP 475
The paper deals with various aspects of the systematics, ecology and biology of the little known pholad wood-borer, Xylophaga dorsalis (Turton) of the Trondheimsfjord (Western Norway). Diagnostic characters of the species have been given based on examination of fresh living specimens and accommodating the several morphological variations. A key to the identification of Norwegian species of Xylopha...

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...

Investigations into the biology of Meruliporia incrassata
2004 - IRG/WP 04-10508
The dry rot fungus Meruliporia incrassata (Berk. and Curt.) Murr. is a highly destructive brown rot wood decay fungus and is a significant pest of wooden structures. The fungus, know commonly as ‘Poria’, is characterized in culture by strand mycelium and skin-like surface mycelium. In structural environments it is found to produce prominent water conducting rhizomorphs, is a copious spore prod...

European House Borer Hylotrupes bajulus Linnaeus in Western Australia: the anatomy of an eradication program
2009 - IRG/WP 09-20403
In January 2004, European house borer (EHB) Hylotrupes bajulus Linnaeus was detected in Perth, Western Australia. A containment program was set up and expanded to a full eradication campaign in 2008. The program is projected to eradicate EHB by 2021. This paper describes research work and assumptions on the biology and behaviour of EHB in Western Australia, surveillance and control methods, commun...

What Can Fecal Pellets Tell Us About Cryptic Drywood Termites (Isoptera: Kalotermitidae)?
2009 - IRG/WP 09-20407
Drywood termites (Isoptera: Kalotermitidae) are serious economic pests of both plants and seasoned wood (furniture, wood frame structures). Currently, five species of kalotermitids are known to occur in the Hawaiian Islands: Neotermes connexus, Incisitermes immigrans, Incisitermes minor, Cryptotermes brevis, and Cryptotermes cynocephalis. These termites are difficult to detect and observe due to ...

Towards Understanding the Biology of Wood Decay
2010 - IRG/WP 10-10739
Our previous research has focused primarily on ways to identify the wood decay fungi and microbial community. We continue to explore this complex and dynamic community and its interactions through microbial community ecology studies, gene expression interactions and proteomics. However, in order to better understand the mechanisms of fungal decay, we have sequenced the genome of a copper tolerant...

What molecular biology can tell us about the biodegradation of lignocellulose: the utilization of molecular techniques for the detection, identification and enhanced understanding of wood degrading organisms
2013 - IRG/WP 13-20528
Molecular techniques are now routinely used in the identification, detection and analysis of wood degrading organisms. An overview of some of the early work on nucleic acid isolation and characterization will be followed by a discussion of the power of sequencing and other procedures for better understanding: the mechanisms involved in the biological degradation of wood, the metabolic basis of pre...

Study on Biological Distribution to Conserve the Tripitaka Koreana woodblocks in Haeinsa Temple
2015 - IRG/WP 15-10844
Tripitaka Koreana is the Wood-carved Buddhist scriptures which were made in 13th century. And Janggyeong Panjeon that is depository for the Tripitaka Koreana was built in 15th century. In recent days, biological damage becomes a serious problem to wooden cultural heritage including historical wooden buildings with global warming. In this study, termite monitoring on whole Haein-sa temple area and ...
