DEET repels ORNery mosquitoes.
D EET ([N-N]-diethyl-mtoluamide) is widely used around the world as a repellent for mosquitoes and other biting insects. It was originally identified by a structure–activity study using synthetic compounds (1). Recently, a number of new compounds with similar activity [e.g., picaridine (2)] have been identified, but DEET remains the gold standard. Despite a tremendous number of studies (3), how...
متن کاملRepellent compound with larger protective zone than DEET identified through activity-screening of Ir40a neurons, does not require Or function
The widely used insect repellent DEET has a limited spatial zone of protection, requiring it to be applied over all exposed areas of skin. Identification of insect DEET-sensing neurons expressing a highly conserved Ionotropic receptor, Ir40a, provides an opportunity to identify new structural classes of volatile agonists as potential spatial repellents. By imaging the activity of the Ir40a+ neu...
متن کاملAedes aegypti Mosquitoes Exhibit Decreased Repellency by DEET following Previous Exposure
DEET (N,N-Diethyl-m-toluamide) is one of the most widely used mosquito repellents. Although DEET has been shown to be extremely effective, recent studies have revealed that certain individual insects are unaffected by its presence. A genetic basis for this has been shown in Aedes aegypti mosquitoes and the fruit fly Drosophila melanogaster, but, for the triatomine bug, Rhodnius prolixus, a decr...
متن کاملEffectiveness of soap formulations containing deet and permethrin as personal protection against outdoor mosquitoes in Malaysia.
Two soap formulations, both containing 20% deet and one each containing permethrin at 0.5 and 1.0%, respectively, were applied to exposed arms and legs of volunteers as personal protection against outdoor human biting mosquitoes in six locations on Penang Island, Malaysia. The predominant mosquito species collected from these locations were Aedes albopictus, Mansonia uniformis, Culex gelidus, A...
متن کاملEffectiveness of repellent formulations containing deet against mosquitoes in northeastern Thailand.
Formulations of the repellent diethyl methyl benzamide (deet) were evaluated against mosquitoes in field tests conducted in Sisaket Province, northeastern Thailand. Thirty-three percent deet in an applicator stick provided > or = 87.1% protection against primarily Culex vishnui, Cx. gelidus, and Cx. tritaeniorhynchus for up to 5 h, and 50% deet in ethanol provided > or = 93.3% protection agains...
