Detection of feeding behaviour of termites using AE monitoring
1991 - IRG/WP 1514
Using acoustic emission (AE) monitoring, the feeding activity of the termite inhabiting a wood specimen was investigated. The amplitude and the rate of AE from the specimen of Coptotermes formosanus Shiraki was larger than that of Reticulitermes speratus Kolbe. The AE event rate was higher in the specimen with soldiers than without soldiers. The AE event rate decreased according to the resistance ...

Evaluation by experimentation on site of a new method for termite control
1996 - IRG/WP 96-10173
A new concept of subterranean termite control consists of the installation of toxic baits in or around the infested construction. Dow Elanco has developed a bait system based on Hexaflumuron. This active ingredient is an insect growth regulator with slow acting effect. A lot of trials were conducted in the USA, but none in France until now. We realised on site experiments, in order to estimate the...

Model of termite distribution in Portugal - Follow-up
2003 - IRG/WP 03-10470
In Portugal, subterranean termites of the genus Reticulitermes are indigenous and a well-established pest of wood in service. Mapping their distribution has therefore become important. A field sampling campaign was established along a North-South transect based on 50x50 km cells (Universal Transverse Mercator grid system, UTM). A variety of typical habitats, ranging from forest sites of Eucalyptu...

Cuticular hydrocarbons for species determination of tropical termites
1990 - IRG/WP 1465
Insect species have unique mixtures of cuticular hydrocarbons in the protective wax of their integument. We use hydrocarbons to evaluate similarities among termite populations. Our assumption is that colonies with similar hydrocarbon profiles are closely related. We have collected Reticulitermes in California from areas suspected to have only Reticulitermes hesperus or Reticulitermes tibialis. The...

Evaluation of mark-release-recapture dyes for Reticulitermes grassei (Clément) (Isoptera: Rhinotermitidae)
2004 - IRG/WP 04-20305
To enumerate foraging territories of termite populations, mark-release-recapture (MRR) appears a more satisfactory method than destructive sampling. Marking of termites has been pioneered by the use of ingested dyes and, accordingly,six candiate dyes were evaluated at several concentrations in Reticulitermes grassei (Clément) workers. Only two of the dyes, neutral red and nile blue A provided co...
