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...

Tunneling ability of subterranean termites through termiticide-treated soil
1988 - IRG/WP 1375
A test apparatus was designed to facilitate accurate measurement of termite penetration into termiticide-treated soil; three termiticides at 500 ppm were evaluated. Coptotermes formosanus Shiraki workers tunneled significantly farther into chlordane-treated soil than did Reticulitermes flavipes (Kollar). Both species only slightly penetrated chlorpyrifos-treated soil. Neither species penetrated so...

Preliminary evaluation of borate baits and dusts for eastern subterranean termite control
1990 - IRG/WP 1433
Borates are of potential use in the development of baiting systems for subterranean termite control. In the 15-day laboratory assays reported here, the oral toxicity of disodium octaborate tetrahydrate to Reticulitermes flavipes (Kollar) was evaluated under choice and no-choice conditions. These assays suggest a range of 2500 to 5000 ppm to be applicable in developing baits, and that concentration...

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...

Preference of the Formosan subterranean termite for wood previously damaged by conspecifics
1988 - IRG/WP 1338
In a laboratory choice test, groups of termites from five colonies of Coptotermes formosanus Shiraki were presented with wood blocks which had sustained previous termite damage: 1) by nestmates, 2) by conspecifics from another colony, 3) by another termite species, Reticulitermes virginicus Banks, and 4) no damage. Coptotermes formosanus preferred wood previously damaged by conspecifics over that ...

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...

Wood protection by surface treatment of two borate preservatives, TIM-BOR® and BORA-CARE®, for the formosan subterranean termite and eastern subterrean termite
1993 - IRG/WP 93-10044
TIM-BOR® (disodium octaborate tetrahydrate: DOT, Na2B8O134H2O) and BORA-CARE® (40% DOT in ethylene glycol) are two borate products marketed for treating wood in use by brushing or spraying onto the wood surface. The active ingredients presumably diffuse into wood by the 10-15% existing wood moisture. Few data, however, are available to demonstrate the diffusion rate. Su & Scheffrahn (1991) s...

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...

Evaluating the natural durability of native and tropical wood species against Reticulitermes flavip
2004 - IRG/WP 04-10539
Environmental pressures to eliminate arsenate from wood preservatives has resulted in voluntary removal of CCA for residential applications in the United States. A new generation of copper organic preservatives has been formulated to replace CCA for decking and in-ground applications but there is no guarantee that these preservatives represent a permanent solution to all related problems. There...
