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...

European laboratory termite testing
1986 - IRG/WP 1299
As with all testing of wood preservatives the evaluation of the resistance to termites of treated wood requires methodology which is approriate to, and can be readily extrapolated to, the practical situation. Thus not only must the variations in possible treatment systems be taken into account (eg dip, brush or pressure application) so too must the range of termite species and the type of exposure...
