Long chain aliphatic methyl ketone series of C7-C15 were tested for repellency activity against the malaria transmitting mosquito Anopheles gambiae s.s. All methyl ketones produced a dose dependent (P < 0.001) repellency response with 2-tridecanone giving comparable protection efficacy to DEET at 10% and 1% concentrations. Aliphatic methyl ketones of C7-C10 had lower activity than those of C11-...

Mosquito repellent lotions generally use ingredients such as diethyltoluamide (DEET). DEET has been mixed by the manufacture of commercial mosquito and used consumers without regard to consequences if it is continuing used. Though many natural plants, especially marine plants can also provide same benefits a repellent. Therefore, in this study aim was make lotion based on seaweed (Sargassum pol...

Sir, Picaridin, a piperidine derivate, is a promising insect repellent that has been available to the consumer since 1998 (1). Picaridin protects against arthropods in a similar fashion to diethyl toluamide (deet), which is considered the gold standard compound (2, 3). Picaridin is also better tolerated than deet (1, 4), a fact that has encouraged its use in repellent formulations. We describe ...

Six controlled-release personal-use topical insect/arthropod repellent formulations of diethylmethylbenzamide (deet) were evaluated in an environmental chamber on volunteers for repellency against the mosquitoes Aedes aegypti and Ae. taeniorhynchus under three climatic regimens: basic variable high humidity (tropical environment), basic constant high humidity (forested and wet environment) and ...

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 protection from biting for between 6 a...

The efficacy of repellents against Anopheles darlingi, the main malaria vector in Bolivia, was evaluated. This mosquito has a peak in biting activity early in the evening. Three natural repellents (1 eucalyptus based, 1 neem based, and 1 containing several repellent essential oils) were tested in comparison with 15% deet in human landing catches in Bolivia. The eucalyptus-based repellent contai...
