Abstract

We evaluated the efficacy of fipronil baits in suppressing or eliminating field colonies of Microtermes mycophagus (Desneux) (Blattodea: Termitidae) an important subterranean termite pest in Pakistan. We tested two doses (10 and 30 ppm) of fipronil in toilet paper baits, chosen from laboratory repellency tests. We monitored four colonies for foraging activity for one month before baiting, and mapped foraging territories with termites marked with Nile Blue A and agonistic tests. Before the fipronil baits were installed there were averages of 782-1938 workers and soldiers per bait station in the four colonies. After baiting, the colonies were eliminated as there were no workers per bait station, whereas the control colony had an average of 1142 workers per bait station. The three possibly eliminated colonies consumed around 47 mg of fipronil formulation (4.7 mg active ingredient) in 45- 90 days. Our results suggest that baits containing fipronil could provide an economical and feasible alternative for the management of M. mycophagus in structures and buildings in Pakistan.

Abstract

The article discusses a study on a global taxonomic road map for species validity and distribution of an economically important subterranean termite genus Coptotermes. Topics discussed include a review of all named species within the genus, their systematic scrutiny according to the region of their original description, and the number of species names within Coptotermes that conformed to the rules of the International Code of Zoological Nomenclature (ICZN).

171. Synthesis of C60H2 by rhodium-catalyzed hydrogenation of C60

Author

Abstract

A mixture of hydrogenated compounds results from the reduction of C60 with rhodium on alumina and hydrogen in deuterated benzene (C6D6) at ambient temperature and pressure. H NMR facilitates the characterization of the key product, C60H2, obtained in 14% yield. The yield of C60H2 decreases within 24 hours of attaining peak concentration.
