Mosquitoes transmit pathogens that result in diseases harmful to human, livestock, and wildlife hosts. Numerous measures can be used to reduce insect-borne disease risk to humans, and one approach is the use of topical repellents to prevent host-seeking arthropods from taking a blood meal. A current emphasis in the development of new repellents is that they be safe. Therefore, natural products sources are increasingly being explored. Compounds from plants of the mint family (Lamiaceae) have… Expand
Identification of essential oil components from Conradina canescens
canescens Gray (false rosemary) is a common evergreen shrub, endemic to a small area of west Florida and adjacent Alabama and southern parts of Mississippi, USA. In this work, essential oils of C.Expand
Larvicidal Properties of Botanical Extracts of Lawsonia inermis against Anopheles stephensi
This study suggests that L. inermis extract can be used as an alternative larvicidal compound during the IPM programs for the An. Expand
Composition of the Essential Oil of Pink Chablis Bluebeard (Caryopteris x clandonensis 'Durio') and Its Biological Activity against the Yellow Fever Mosquito Aedes aegypti
Against the yellow fever mosquito, the essential oil exhibited mild repellency compared to DEET (N,N-diethyl-3-methylbenzamide) as a reference standard and exhibited weak activity as a mosquito larvicide. Expand
Determination of emission characteristics of volatile compounds from mosquito repellents (MRs) by headspace and chamber methods, and indoor levels related to use of MRs
Although the use of mosquito repellents (MRs) may lead to several adverse health effects, very limited information is available on exposure to their emissions. As such, the present study evaluatedExpand

The extraction and chromatographic determination of the essentials oils from Ocimum basilicum L. by different techniques
Three different techniques (maceration, sonication and extraction in microwave field) were used for extraction of essential oils from Ocimum basilicum L. The extracts were analyzed by TLC/HPTLCExpand
Essentials Oils Determination from Satureja hortensis L. by Chromatographic Techniques
Abstract Three different techniques (maceration, ultrasonic and microwave solvent assisted extraction) were used for extraction of essentials oils from Satureja hortensis L. The extracts wereExpand
The Genus Conradina (Lamiaceae): A Review
The purpose of the present review is to highlight the recent advances in current knowledge on Conradina species and to compile reports of chemical constituents that characterize and differentiate between Conradine species. Expand
Analysis of Iranian rosemary essential oil: application of gas chromatography-mass spectrometry combined with chemometrics.
Multivariate curve resolution (MCR) approach was used to overcome the problem of background, baseline offset and overlapping/embedded peaks in GC-MS to characterization of the components of Iranian rosemary essential oil using gas chromatography-mass spectrometry. Expand
Luminescence and fluorescence of essential oils. Fluorescence imaging in vivo of wild chamomile oil
It is demonstrated how the fluorescent signal can be monitored for at least three hours on the skin of living mice treated with wild chamomile oil, and the results encourage development of this technique to investigate the properties of drugs and cosmetics containing essential oils. Expand

In the context of agricultural pest management, botanical insecticides are best suited for use in organic food production in industrialized countries but can play a much greater role in the production and postharvest protection of food in developing countries. Expand
Repellency of essential oils of some Kenyan plants against Anopheles gambiae.
Four synthetic blends of the major components of the essential oils were found to exhibit comparable repellent activity to the parent oils, and eight constituents of the different oils exhibited relatively high repellency. Expand
Repellency and toxicity of aromatic plant extracts against the mosquito Culex pipiens molestus (Diptera: Culicidae).
The insecticidal activities of essential oil extracts from leaves, flowers and roots of aromatic plants against fourth-instar larvae of the mosquito Culex pipiens molestus Forskal were determined.Expand
Effects of essential oil formulations on Ceratitis capitata Wied. (Dipt., Tephritidae) adult flies
The effects on adult Ceratitis capitata of the ingestion of formulations containing different concentrations of some essential oils were examined and it was found that even small quantities of essential oils have a depressive effect on the nervous system. Expand
In search of allelopathy in the Florida scrub: The role of terpenoids
The hypothesis was tested that allelopathic agents released from fire-sensitive plants of the Florida scrub community deter the invasion of fireprone sandhill grasses. The structures of theExpand
Isolation and identification of mosquito bite deterrent terpenoids from leaves of American (Callicarpa americana) and Japanese (Callicarpa japonica) beautyberry.
Bioassay-guided fractionation of C. americana extracts using the yellow fever mosquito led to the isolation of alpha-humulene, humulene epoxide II, and intermedeol and a newly isolated terpenoid (callicarpenal), which showed significant repellent activity against A. aegypti and Anopheles stephensi in bite deterrent studies.

Piperitenone Oxide as Toxic, Repellent, and Reproduction Retardant Toward Malarial Vector Anopheles stephensi (Diptera: Anophelinae)
Results indicated the higher efficacy of piperitenone oxide than the crude essential oil of M. spicata variety viridis in all the bioassay experiments, and developmental toxicity studies showed the significant developmental inhibition potential of the compound and oil. Expand
Chemical composition, toxicity and mosquito repellency of Ocimum selloi oil.
Results showed that Ocimum selloi oil is an effective mosquito repellent that presents a low acute toxicity, poses no mutagenic risk and seems not to be irritating to human skin. Expand
Repellency of Oils of Lemon Eucalyptus, Geranium, and Lavender and the Mosquito Repellent MyggA Natural to Ixodes ricinus (Acari: Ixodidae) in the Laboratory and Field
In field tests in tick-infested areas in central Sweden, tick repellency of MyggA Natural and C. citriodora oil was tested by the blanket-dragging technique for 4 d during a 6-d period and declined significantly from day 1 to day 6. Expand
