“…An older, and more widely applied strategy of vector manipulation is the use of repellents such as N,N-diethyl-3-methylbenzamide (DEET) (Katz et al 2008). DEET has been in use for more than 50 years, and is effective against mosquitoes, sand flies and ticks.…”

“…Finally, as it is increasingly becoming apparent that the olfactory behaviour of insects and ticks is often mediated by parasites, a chapter on the latest knowledge of this field of science is also included. Odorants are not only used to attract insects and ticks, but they can also be used to protect blood hosts from being attacked (Katz et al 2008). In many cases odorants act as deterrents or repellents, and where applicable, this aspect of olfaction is discussed as well.…”

“…[7][8][9][10][11][12] O N, N-dietil-3-metilbenzamida, também conhecido como Deet, é o repelente mais utilizado. 13 É encontrado em concentrações de 5% a 100% (a maioria, menos de 40%) em loção, gel, aerossol, spray e solução para impregnar roupas na lavagem.…”

Resumo: FUNDAMENTOS: No Brasil, doenças provocadas por picadas de insetos são frequentes, o que torna extremamente importante a execução de medidas profiláticas de forma adequada, sobretudo, em áreas endêmicas como a Amazônia, que recebe um grande contingente de visitantes, a trabalho ou turismo. OBJETIVOS: Avaliar o uso dos repelentes de insetos disponíveis no mercado por militares que costumam realizar missões em ambiente de selva, na região amazônica. MÉTODOS: Foram selecionados cinquenta e um militares da região amazônica que responderam um questionário em junho/2008. RESULTADOS: 63,7% dos militares usaram produtos contendo Deet na concentração máxima de apenas 15%, que possui mínima ação de repelência; 36% relataram usar protetor solar associado, o que levou a um risco maior de intoxicação; 36,4% fizeram uso de um repelente natural em suas missões; dois militares usaram vitamina B e consideraram a sua ação de repelência ineficaz. CONCLUSÕES: Os repelentes à base de Deet utilizados pelo grupo estudado apresentam concentrações inferiores às consideradas seguras para uso em ambiente de selva. Foi frequente a associação do Deet com protetor solar, que é uma combinação potencialmente tóxica. Os repelentes naturais à base de andiroba e copaíba apresentaram o maior grau de percepção de proteção. Palavras-chave: Deet; Mordeduras e picadas de insetos; Repelentes de insetos Abstract: BACKGROUND: In Brazil, diseases caused by insect bites are frequent. Therefore, it is extremely important that prophylatic measures are adequately carried out, especially in endemic areas such as the Amazon which receives a great number of visitors, for both business and tourism purposes.. OBJECTIVES: To evaluate the use of insect repellents available in the market by military personnel who often go in missions in the middle of the jungle, in the Amazon region. METHODOLOGY: Fifty -one militaries in the Amazon region were selected and they answered a questionnaire in June/2008. RESULTS: 63,7% of the militaries used products that contained Deet in the maximun concentration of only 15% that has minimum repellent action; 36% reported to combine these products with sun protective products which increased the risk of intoxication; 36,4% used a natural repellent during their missions; two of the militaries participants used vitamin B and considered their repellent action ineffective. CONCLUSION: The repellents that contain Deet and which were used by the group present concentrations that are lower than the concentrations considered safe for using in the jungle. It was frequent the combination of Deet with sun protective products ,which is a potentially toxic association. Natural repellents that have "andiroba" and" copaíba" as components presented a higher perception of protection from the participants.

“…Although the use of synthetic repellents tends to be more effective than natural repellents, the development of insect resistance has restricted the usefulness of synthetic repellents. 17) Thus, plant-based repellents may be comparable to, or even somewhat better than, synthetics, depending on the formula. Many plant essential oils and their components have been shown to have good repellent activity, [18][19][20] for example, Piper guineense (black pepper) seed oil exhibits both insecticidal and repellent activity against the stored product insect pests.…”

Repellent activity of citrus oils against the cockroaches Blattella germanica, Periplaneta americana and P. fuliginosa

et al. 2009

The repellent efficacy of 17 essential oils against the German cockroach, Blattella germanica was examined using a T-tube olfactometer. Five oils repelled B. germanica with good efficacy, ranging from 70.0 to 96.7%. Four of these oils, grapefruit, lemon, lime, and orange, were from the citrus family Rutaceae. These citrus essential oils showed similar repellent activity against two more cockroach species, such as Periplaneta americana and P. fuliginosa. Gas chromatography (GC) and GC-mass spectrometry analyses revealed that the major components responsible for the repellent activity of the citrus oils were limonene, b-pinene and g-terpinene. Limonene appears to be the main component responsible for the repellent activity rather than b-pinene and g-terpinene. The repellent efficacy of these components varied with different doses and the cockroach species tested. It is likely that minor components of the oils also contributed to the overall repellent activity of citrus essential oils, except orange oil. The activity of orange oil is almost solely attributed to the activity of limonene. Also, the repellent activity of citrus oil and that of each of the terpenoids makes little difference to the efficacy of a repellant against the three species of cockroaches.
