N,N-Diethyl-m-toluamide, also known as DEET or m-DET, is an aromatic amide that is an effective insect repellent for control of biting flies, biting midges, black flies, chiggers, deer flies, fleas, gnats, horse flies, mosquitoes, nosee-ums, sand flies, small flying insects, stable flies, and ticks. DEET was first developed by the U.S. Department of Agriculture for military use in 1946 and was ...

OBJECTIVE To determine the extent and nature of health-related behaviours and outcomes among members of the first foreign medical team to arrive in Aceh, following the Boxing Day tsunami in 2004. METHODS A cross sectional survey of team members 4 weeks after return from Aceh. RESULTS Compliance with antimalarial chemoprophylaxis and insect repellent was high while in Aceh, but only one-thir...

DEET is the most widely used insect repellent worldwide. In Drosophila olfactory receptor neurons (ORNs), DEET is detected through a mechanism employing the olfactory receptor, OR83b. However, it is controversial as to whether ORNs respond directly to DEET or whether DEET blocks the response to attractive odors. Here, we showed that DEET suppressed feeding behavior in Drosophila, and this effec...

The insect repellent N,N-diethyl-m-toluamide (DEET) has been reported to inhibit AChE (acetylcholinesterase) and to possess potential carcinogenic properties with excessive vascularization. In the present paper, we demonstrate that DEET specifically stimulates endothelial cells that promote angiogenesis which increases tumor growth. DEET activates cellular processes that lead to angiogenesis in...

Mycoviruses are usually transmitted horizontally via hyphal anastomosis and vertically via sexual/asexual spores. Previously, we reported that a gemycircularvirus, Sclerotinia sclerotiorum hypovirulence-associated DNA virus 1 (SsHADV-1), could infect its fungal host extracellularly. Here, we discovered that SsHADV-1 could infect a mycophagous insect, Lycoriella ingenua, and use it as a transmis...

Olfactory cues play decisive roles in the lives of most insect species, providing information about biologically relevant resources, such as food, mates, and oviposition sites. The nocturnal moth Manduca sexta feeds on floral nectar from a variety of plants (and thus serves as a pollinator), but females oviposit almost exclusively on solanaceous plants, which they recognize on the basis of olfa...

The efficacy of commercial insect repellents was evaluated against Aedes albopictus (Skuse) (Diptera Culicidae) by means of arm in cage assays. The tested products included a DEET-based repellent (Off Spray), a commercial preparation of Icaridin (Autan Active), three formulations containing DMP (Helpic, Sandokan Body Gel, and Sandokan Body Spray) and four plant-derived products (Orphea, Senzazz...

One of the criteria for an effective bird repellent in a pest management context in New Zealand is that possum (Trichosurus vulpecula) and ship rat (Rattus rattus) kills remain high where repellents are used in poison baits. Repellents were used in baits applied within different treatment blocks as part of a large aerial 1080 operation in November 2013 near Haast on the West Coast of the South ...

Nepetalactone, the primary component of catnip oil, was compared with the repellent N,N-diethyl-3-methylbenzamide (deet) for its ability to affect the host-seeking ability ofAedes aegypti (L.). A triple cage olfactometer was used to bioassay each substance and to assess its attraction inhibition (spatial repellent) attributeswhencombinedwith the following attractants: carbondioxide, acetone, a ...
