Visualization of Feeding Process of Larvae of the Wood-boring Beetles Using X-ray Computer Tomography
2019 - IRG/WP 19-10953
X-ray computer tomography (CT) was applied to observe the movement of the larvae of the wood-boring beetles Lyctus brunneus, Lyctus africanus, and Heterobostrychus aequalis inside the infested wood specimens. The larvae bred with artificial diet were inserted into the hole of wood specimens of rubber wood Hevea spp. or Japanese oak Quercus crispula. The wood specimens with larvae were scanned usin...

A medium for mass culturing of a bamboo boring beetle Dinoderus minutus Fabricius
1983 - IRG/WP 1182
The bamboo is a traditional product of Japan. But its susceptibility to insects is one of the most important problems. The author has found that for the determination of the effectiveness of insecticides it is very easy to obtain sufficiently numerous adults of Dinoderus minutus by using Buckwheat Cake. The Buckwheat Cake is prepared with buckwheat flour and thin paper. The author has previously f...

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...

The resistance of fifteen Indonesian tropical wood species to the powder post beetle Heterobostrychus aequalis
1990 - IRG/WP 1429
A preliminary laboratory test on the resistance of 15 tropical wood species to Heterobostrychus aequalis has been carried out using small samples of 7.5 x 5 x 1.5 cm³. The results reveal that Pinus merkusii and Agathis borneensis are very susceptible to Heterobostrychus aequalis. Other 13 species vary between susceptible to resistance There is no signifisant relation between starch content and th...

Effects of some essential oils on wood destroying organisms
1993 - IRG/WP 93-10047
Three wood destroying fungi: Botryodiplodia theobromae Pat. (stain), Gloeophyllum sepiarium (brown rot), and Pycnoporus sanguineus (white rot) were exposed to six plant essential oils: the peppermint, kaffir lime or leech lime, lavender, tarragon, holy basil, and the eucalyptus. The peppermint oil showed most effective to inhibit fungal growth, while eucalypus oil was the least effective. The othe...

The development of a screening method for the activity of pyrethroids against wood boring marine crustaceans, Limnoria spp
1978 - IRG/WP 443
The present work is concerned with the develepment of a suitable bio-assay technique to determine the biological activity (contact action) of pyrethroids against Limnoria spp. Estimates of the toxicity of three pyrethroids, permethrin, cypermethrin and decamethrin (the structures of which are shown in Fig. 1.) to the marine borer have been obtained....

Bifenthrin, a new insecticide for the control of termites and wood-boring insects
1995 - IRG/WP 95-30076
Bifenthrin, a new insecticidal compound Bifenthrin has been extensively tested, to determine its potential use to control termites and other wood destroying insects. Bifenthrin is effective at extreme low rates which can minimize human and environmental exposure to the product. Results of tests carried out by several research institutes and by FMC in different countries will be presented. The phys...

Behavioural and morphological adaptations to tidal inundation in the adult wood boring weevil Pselactus spadix Herbst
1999 - IRG/WP 99-10308
Pselactus spadix tunnels wood in the mid intertidal to high intertidal zones and is submersed for several hours with each tide. The submergence and subsequent recovery behaviour, together with sub elytral morphology of P. spadix was investigated and compared to a terrestrial wood borer of the same subfamily Euophryum confine. An investigation of adult activity following submersion in seawater show...

Description of a trial with wood preservatives against marine wood boring organisms
1975 - IRG/WP 412
Wood situated in sea water along the Atlantic coasts of the Nordic countries is attacked by marine wood boring organisms. Timber constructions in these waters therefore must be preservative treated. In order to evaluate the effect of various preservatives against marine wood borers, the Nordic Wood Preservation Council (NWPC) organized a rather extensive trial in 1972. In the absence of and while ...

Respiratory response of the wood boring teredinid, Lyrodus pedicellatus (Quatrefages) to copper stress
2004 - IRG/WP 04-10528
Wood boring teredinid molluscs engulf most of the wooden particles scrapped by them while actively boring into wood, obtaining nourishment for their metabolic activities. In order to protect the wooden structures from the biodeteriorating activity of such organisms, the wood is treated with different chemical formulations to prolong their service life. Copper chrome arsenic (CCA) is one such woo...

Isolation of a putative endogenous endo-ß-1,4-glucanase (cellulase) from the midgut diverticulae of the wood-boring crustacean, Limnoria quadripunctata
2003 - IRG/WP 03-10494
Over the last 75 years, many workers have conducted research into the digestive biochemistry of Limnoria. Cellulolytic enzymes have been detected in crude extracts, although whether these are of endogenous or microbial origin has been in question. To elucidate the source of these enzymes, RNA was isolated from the midgut diverticulae of Limnoria quadripunctata. Reverse transcription polymerase ...

Marine wood-borer test with preservatives on the coasts of Turkey
1995 - IRG/WP 95-10091
Marine wood-borer tests were carried out on the coasts of Turkey (Marmara, Mediterranean Sea and Black Sea). Sapwood blocks of 8 x 15 x 30 cm³ in size from Scots pine, Bornmüller's fir oriental beech and sessile oak were used. The test blocks were treated with CCB-salts by full cell process and coal tar creosote by empty cell process. The test blocks were installed on exposure sites bef...
