Comparative evaluation of the barrier effect against Hylotrupes bajulus L. of different types of wood preservative
1986 - IRG/WP 1307
This paper settles the difference of contact action against females of Hylotrupes bajulus the likelihood of egg-laying, the ovicide effect and the hazards of development of newly hatched larvae between some preservatives belonging to three differents types: mineral waterborne products, organic products and emulsions. The results show that against females, the action is fast with organic products, ...

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...

Geographical distribution of termites inside buildings in France
1991 - IRG/WP 1512
Since several years, data concerning infestations of buildings by termites are collected by CTBA. Most of them come from of the localizations communicated by the Pest Control Operators in the frame of the Approval. Maps were settled in 1975, 1981 and lastly in 1989. These maps show that the areas infested by termites are extending. Processing of data is described....

Comparison between the Hylotrupes bajulus strains of different European laboratories
1980 - IRG/WP 1118
In several European countries, wood preservatives of the same formulation are subjected for the quality label to particular tests according to standards established by the CEN. The different laboratories which carry out these tests have had their cultures for many years. The insects are kept in optimal nutritional and climatic conditions and have always mated amongst themselves. On the one hand, e...

In situ timber treatments by spraying. Distribution of preservative in wood
1991 - IRG/WP 3678
This study was carried out in order to make the Pest Control Operators able to achieve correct treatments and enhance their efficacy. It was carried out in two steps: 1) in laboratory, to learn the influence of various parameters like spraying pressure, use of repeated applications, distance from nozzle to wood; 2) in situ on roof timber of five buildings. In this case, the applications of the pre...

Make ready of a detection system for insect attack by acoustical method
1996 - IRG/WP 96-10183
A contract CRAFT of European research allowed to build a detector prototype able to diagnose on site the presence of Hylotrupes bajulus and termites, even during the first stages of infestation when no sign of activity is visible. Based on non destructive control technics, the device picks up the acoustical waves emitted by the insects in the wood fibers. The amplification and the filtering of the...

Silafluofen: Novel chemistry and versatility for termite control
1995 - IRG/WP 95-30069
A novel silicon - containing insectizide, HOE 084498 ('Silafluofen'), with a favourable toxicological profile, has shown activity against a broad spectrum of agricultural and environmental health pests. Results from laboratory and field studies around the world have demonstrated that silafluofen is effective at protecting timber from attack by various species of termite and wood-...

Anobium punctatum De Geer (Coleoptera Anobiidae)
1980 - IRG/WP 1103
Anobium punctatum de Geer (1) est un Coléoptère qui appartient au sous-ordre des Teredilia et à la famille des Anobiidae. Cet insecte a été décrit pour la première fois par Charles de Geer, entomologiste Suédois dans ses "Mémoires pour servir à l'histoire des insectes" parues en 1774, sous le nom vulgaire de Vrillette pointillée et en latin " Ptinus (punctatus) griseo fuscus". ...

Laboratory method for testing the effectiveness of soil termiticides
1992 - IRG/WP 92-1561
In France, the protection of buildings against termites is based on a chemical treatment of wood, soil and walls. Because of the withdrawal of aldrin from the market, the need of new soil termiticides has appeared. Therefore, a laboratory method derived from Cymorek's method has been developped to assess their effectiveness. Some points are developed like the type of soil, the number of t...

Risk of extension of Hylotrupes bajulus attack in glued laminated timber
1977 - IRG/WP 278
Although efficient work-methods and maintenance procedures, which prevent the wood from becoming damp and are therefore successful in considerably reducing and even in excluding the risks of decay, such methods are ineffective in eliminating the risks of infestation and destruction of timber by the House Longhorn Beetle, Hylotrupes bajulus, the chief enemy of softwood timber structures. The possib...
