The mosquito feeding and ovipositional repellency of the major monoterpenoid present in the volatile oil ofHemizonia fitchii (Asteraceae), i.e., 1,8-cineole, was investigated. Although 1,8-cineole did not exhibit any significant mosquito larvicidal activity, it was moderately effective as a feeding repellent and highly effective as an ovipositional repellent against adultAedes aegypti (yellow fever mosquito). The ovipositional repellency of 1,8-cineole, coupled with the presence of… 


Findings indicate that a spray-type solution containing 2% α-terpinene may serve as an alternative mosquito repellent.

Chemical Composition and Repellency of Essential Oils from Four Medicinal Plants Against Ixodes ricinus Nymphs (Acari: Ixodidae)

The essential oils of the dry leaves of Rosmarinus officinalis, M. spicata, and O. majorana showed strong repellency against the ticks 100, 93, and 84.3%, respectively, whereas O. basilicum only showed 64.5% repellencies.

Evaluation of the Mosquito Repellent Activity of Nano-sized Microemulsion of Eucalyptus globulus Essential Oil Against Culicinae

Preparation of nano-sized microemulsion could delay the volatility of eucalyptus essential oil and volatile oil release from formulations and consequently increase protection time against mosquitoes.

Repellent and Larvicidal Activity of the Essential Oil From Eucalyptus nitens Against Aedes aegypti and Aedes albopictus (Diptera: Culicidae)

Results indicate that the repellent effect of E. nitens is not due only to the main component, 1,8-cineole, but also that other compounds may be responsible.

Baeckea frutescen L. essential oil was tested with Aedes aegypti larvae at various concentration levels

Ujung Atap (Baeckea frutescens L.) essential oil is one of them that has the potential as a bioinsecticide and it is found that produces more and better essential oil than fresh leaves.

Composition and biological activity of essential oils against Metopolophium dirhodum (Hemiptera: Aphididae) cereal crop pest.

The essential oils from S. areira, R. officinalis and T. terniflora could be used as an alternative in the management of M. dirhodum and rosemary essential oil was the most toxic to winged adults.

Study of the Active Compound in the Essential Oil of Myrtus Communis L.

This study appears of the major volatile compounds in the essential oil of myrtle leaves because of its significant medical and economic benefits. The essential oil composition of Myrtus communis

Repellency and insecticidal activity of seven Mugwort (Artemisia argyi) essential oils against the malaria vector Anopheles sinensis

Anopheles sinensis is the main vector of malaria with a wide distribution in China and its adjacent countries. The smoke from burning dried mugwort leaves has been commonly used to repel and kill



Insecticidal chromenes from the volatile oil ofHemizonia fitchii

The chromenes exhibited weak to moderate toxicity against Culex pipiens (house mosquito) larvae and Oncopeltus fasciatus (large milkweed bug) nymphs, however, no antijuvenile hormone activity was observed for any of the compounds tested against these insect species.

Inhibition of oviposition by volatiles of certain plants and chemicals in the leafhopperAmrasca devastons (distant)

Oviposition by the leafhopperAmrasca devastans (Distant) on its susceptible host plant, cotton (Gossypium hirsutum var. PS-10), was inhibited by the volatiles of certain plants and by the vapors of

Interference of sonic communication and mating in leafhopperAmrasca devastans (distant) by certain volatiles

Mating between the two sexes in the leafhopperAmrasca devastans was inhibited by cineole vapors surrounding host plant leaves bearing the insects. There was a decline in the percentage of pairs

Seasonal and Site Variation in Costa Rican Euglossine Bees at Chemical Baits in Lowland Deciduous and Evergreen Forests

By attracting male euglossine bees with cineole, eugenol, methyl salicylate, methyl cinnamate, and benzyl acetate in Costa Rican lowland deciduous forest and rain forest, we found no indication of

Biochemical Parallelisms of Repellents and Attractants in Higher Plants and Arthropods

In reviewing the distribution of micromolecular constituents (secondary compounds) that are known to function as defensive repellents* in arthropods, it becomes evident that a large number of
