Screening potential termiticides: Some thoughts and suggestions on methodology
1988 - IRG/WP 1363
While laboratory bioassays on the efficacy of potential termiticides against subterranean termites continues both to dominate and influence research efforts, suggestions are presented for the need to develop laboratory bioassays that more closely simulate "natural conditions". Not only is this considered desirable, but it will offer more confidence in laboratory and field evaluations and their ana...

Determination of bis-(N-cyclohexyl-diazeniumdioxy)-copper in different matrices by photometer, thermal energy analyzer and HPLC
1999 - IRG/WP 99-20179
For the quantitative analysis of bis (N-cyclohexyl-diazeniumdioxy)-copper (Cu-HDO) three analytical methods are used. The employment of the different methods depends on the matrices involved. For several years now, the colorimetric determination of Cu-HDO by photometer has been applied to solutions and concentrates of wood preservatives. In principle, the technique consists of a quantitative conve...
