A eucalyptus-based insect repellent (PMD) with the principal active ingredient p-menthane-3,8-diol was evaluated in the field in comparison with deet. In human landing catches in Tanzania, 3 formulations of PMD were tested against Anopheles gambiae and An. funestus. Repellents, applied to the legs and feet at doses chosen as used in practice, gave complete(More)

A eucalyptus-based insect repellent (PMD) was evaluated against Culicoides impunctatus in Scotland in comparison with deet. In human landing catches, both repellents still afforded 98% protection from biting 8 h after application of 0.5 ml to the forearm. A second trial looking at protection between 8 and 10 h after repellent application showed 99.5%(More)
A nested polymerase chain reaction was used to amplify a fragment of the gene for dihydrofolate reductase of Plasmodium falciparum containing codon 108, where a point mutation, causing a serine to asparagine change, occurs in pyrimethamine resistant parasites. The presence of the mutation was detected by restriction enzyme digestion. Parasites in blood(More)
