“…In the present study, 5 g kg -1 dose were used with similar results. Finally, the clove plant is well studied and has product patents for several uses, with the main substance studied eugenol, probably the active ingredient that causes repellency and insect mortality (Affonso et al, 2012).…”

ndustrial chemicals that control pests in stored seed can cause damage to health by residual effects remaining in the grains. Studies of products with potential insecticide and repellent properties are required to decrease post-harvest losses. Thus, the aim of this study was to evaluate the quality and efficiency of seed treatment in beans stored under the following treatments: dried leaves and crushed laurel (Laurus nobilis L.), rosemary (Rosmarinus officinalis L.) and basil (Ocimum basilicum L.), cinnamon powder (Cinnamomum zeylanicum Breyn) and ground cloves (Syzygium aromaticum L.) over eight months. An untreated control and a treatment with diatomaceous earth were used to compare the results. At the beginning and at 30 days, percentages of normal and abnormal seedlings as well as seeds that did not germinate, mass of onehundred seeds, water content and infested seeds were analyzed. At 210 and 240 days, free choice arena and repellency testswere conducted. Treatments did not affect germination, mass of 100 seeds or water content; however, all plants tested showed a repellent effect on the bean weevil.Keywords: bean weevil, botanical insecticides, free choice arena. RESUMO: Qualidade de sementes de feijão carioca armazenado sob tratamentos com plantas aromáticas de potencial repelente. Produtos químicos industriais que controlam pragas de sementes e grãos armazenados podem causar danos à saúde pelo efeito residual que proporcionam. Assim, são necessários estudos de produtos que apresentem repelência e potencial inseticida e reduzam perdas pós-colheita sem causar danos à saúde. Neste contexto, o objetivo deste trabalho foi avaliar a qualidade e eficiência do tratamento com plantas aromáticas: folhas desidratadas e moídas de louro (Laurus nobilis), alecrim (Rosmarinus officinalis) e manjericão (Ocimum basilicum L.), canela em pó (Cinnamomum zeylanicum Breyn) e cravo moído (Syzygium aromaticum L.), em sementes de feijão carioca armazenadas durante oito meses. Uma testemunha sem tratamento e outra com terra de diatomáceas foram utilizadas para comparação dos resultados. No início e a cada 30 dias foram realizadas as determinações de plântulas normais, anormais, sementes não germinadas, massa de cem sementes, teor de água e sementes infestadas. Os testes de arena de livre escolha e repelência foram realizados aos 210 e 240 dias. Os tratamentos não influenciaram a germinação, massa de cem sementes, teor de água. Entretanto, todas as plantas testadas apresentaram efeito repelente sobre o caruncho do feijão.Palavras-chave: arena de livre escolha, caruncho do feijão, inseticidas botânicos.

“…14 Despite not having its mechanism of action well elucidated yet, N,N-diethyl-3-methylbenzamide (DEET) is the main repellent in use today against A. gambiae. 2,3,4,6,15 Tsitsanou et al 14 suggested that this molecule targets AgOBP 1 , blocking the binding site of the attractive molecules, and published the 3D structure of the AgOBP 1 -DEET complex as the first example of a repellent recognized by an OBP. This achievement should give a significant impulse to the drug design of new repellents as it provides the first known target.…”

“…Next, these molecules are transported to the olfactory receptor neurons (ORN), located in the dendritic membranes at the antenna sensory bristles, driving the mosquito's attention to the potential meal. 3,9,[11][12][13][14] Studies by Biessmann et al 11 have proved the importance of OBP for smell recognition in the search for food, in mating and other activities. 3,12,14 Among the 60 types of OBP coded in the A. gambiae genoma, the Anopheles gambiae odorant binding protein (AgOBP 1 ) was found in higher levels in the antennas of females when compared to males and its levels were observed to reduce when the females feed on blood.…”

Mosquitos são responsáveis pela transmissão de várias doenças causadas por vírus, parasitas e helmintos. Considerando o custo e a complexidade do tratamento dessas doenças, o uso de repelentes para proteção contra mosquitos vetores se torna uma alternativa interessante. Nesse contexto, no presente trabalho foram feitos estudos por ancoramento e dinâmica molecular (DM) de potenciais ligantes da proteína odorante do mosquito Anopheles gambiae (AgOBP 1 ), o principal vetor da malária. Os modos de ligação na AgOBP 1 de moléculas com conhecida atividade atrativa e dos principais componentes do óleo do cravo da índia (Syzygium aromaticum), com potencial atividade repelente, foram comparados com o conhecido repelente N,N-dietil-3-metilbenzamida (DEET). Os resultados sugerem que o acetato de eugenila é um repelente melhor do que o DEET e também revelam as principais características do sítio de ligação da AgOBP 1 importantes para o planejamento de novos e mais eficientes repelentes.Mosquitoes are responsible for conveying various diseases caused by viruses, parasites and helminthes. Considering the cost and complexity of the treatment of these diseases, the use of repellents for protection from the mosquito vectors becomes an interesting alternative. In the present work, docking and molecular dynamics (MD) studies were performed on potential ligands to the odorant binding protein of the mosquito Anopheles gambiae (AgOBP 1 ), the main vector of malaria. The binding modes on AgOBP 1 of molecules with known attractive activities and the main components of the oil of indian clove (Syzygium aromaticum) with potential repellent activities were compared to the known repellent N, . Results suggest the eugenyl acetate as a better repellent than DEET and also reveal the main features of the binding site of AgOBP 1 important to the design of new and more efficient repellents.

The rise of the mosquitoes-transmitted diseases, like dengue, zika and chikungunya in Brazil in the last years has increased concerns on protection against mosquitoes bites. However, the prohibitive prices of the commercially available repellents for the majority of the Brazilian population has provoked a search for cheaper solutions, like the use of the homemade ethanolic extract of Indian clove (Syzygium aromaticum L.) as repellent, which has been reported as quite efficient by the local press. In order to verify this, we performed here the quantification of the main components of this extract through high-performance thin-layer chromatography (HPTLC)-densitometry and evaluated its efficiency as a repellent and its acetylcholinesterase (AChE) inhibition capacity. Our results have proved HPTLC-densitometry as an efficient and appropriate method for this quantification and confirmed the repellency activity, as well as its capacity of AChE inhibition.
