Pesquisadores da Universidade Federal do Amapá investigam o potencial de plantas da Amazônia no controle de mosquitos vetores no Brasil – em especial, o Aedes aegypti, transmite el dengue, da febre chikungunya e do vírus Zika. O estudo analisa extratos vegetais e óleos essenciais das plantas e sintetiza as chamadas nanoemulsões – substâncias concentradas e que têm princípios ativos que podem, por ejemplo, matar larvas de mosquito ou afastar picadas de inseto.

En una entrevista a Brasil, o professor do Departamento de Ciências Biológicas e da Saúde, Raimundo Nonato, informou que a equipe é composta por aproximadamente dez pessoas – três profissionais da biologia e sete da área de ciências farmacêuticas. investigación, según él, está em andamento há pelo menos 12 meses. recientemente, um artigo sobre os avanços alcançados pelo grupo foi publicado na revista norte-americana Plus One.

“Já temos mais de cinco substâncias que se mostraram extremamente eficientes na atividade larvicida e que são oriundas de plantas testadas”, disse Nonato. “A prioridade foi dada por causa da necessidade iminente de desenvolver substâncias que possam colaborar para o controle das larvas de forma ecologicamente mais correta, causando danos menores ao meio ambiente”, terminado.

Pelo avanço dos trabalhos, a previsão do pesquisador é de que, com mais um ano de estudo, a equipe consiga chegar à formulação final desses produtos. En seguida, inicia-se o processo de pedido de patente e o registro na Agência Nacional de Vigilância Sanitária (Anvisa). “Sendo otimista, mais dois anos, no máximo”.

“A Índia, o Paquistão e alguns grupos de pesquisadores nos Estados Unidos já têm estudos bastante avançados na produção de repelentes a partir de extratos naturais e óleos vegetais”, comentou Raimundo Nonato. “A produção, en aquellos casos, tende a ter um custo menor, mas não é algo simples de se fazer. Para que se produza um inseticida natural em grande escala, é necessário dominar técnicas de cultivo e um conhecimento paralelo da parte agronômica”.
