“…Bti is currently the most commonly used bacterium for insecticidal purposes (Silva et al 2014) and is highly effective in controlling A. aegypti larvae (Lima et al 2005;Boyce 2013), without provoking toxic effects in humans, either by ingestion or skin contact (WHO 2004). Moreover, it does not show adverse effects to others animal species and is considered non-pathogenic and non-toxic (WHO 1999).…”

“…Biological control using natural enemies is also employed (Panplona et al 2009;Albeny-Simoes et al 2011, 2012 as well as use of biolarvicides based on Bacillus thuringiensis var. israelensis (Bti) (Arcy et al 2014). The use of chemicals has not been effective in controlling vector populations or the incidence of dengue (Beserra et al 2007), and this results in either immediate damage or future risks to the environment and human health (Gomes Maria Assunta Busato et al 2014).…”

The intense use of synthetic products for the control of Aedes aegypti has led to the development of resistance and imposes health risks to other flora and fauna. This study assessed the larvicidal potential of Melia azedarach (Meliaceae) fruit extract obtained by the supercritical carbon dioxide extraction method and Bacillus thuringiensis var. israelensis (Bti) on second and third instar A. aegypti larvae under laboratory conditions. The assays were performed in disposable cups containing 100 250, 500, 750, 1,000 and 2,000 μg/ml extracts of M. azedarach, and 0.0005, 0.001, 0.0015, 0.002, and 0.0025 g/L of VectoBac WG®; the controls contained only water. Ten active larvae were added to each well, and the number of living larvae was counted each day for 72 h. Treatment efficiency was calculated using Abbott's equation. Insecticidal efficiency increased with M. azedarach extract concentration, with significant effects in the 1.000 and 2.000 μg/mL concentration range. Bti efficiency was 100 % in the first 24 h. The results indicate the possibility of A. aegypti population control using supercritical extracts of M. azedarach.

<p dir="ltr"><span>Atualmente, a utilização de pesticidas químicos em culturas agrícolas tem se tornado cada vez mais frequente. A cafeína é uma das moléculas psicoativas mais consumidas em todo o mundo, no entanto, pouco se sabe sobre as aplicações que ela possui no cenário agrícola. Dessa forma, a presente pesquisa almejou prospectar a utilização da cafeína como um biopesticida em bases nacionais e internacionais de artigos e patentes. Para tal, a busca científica e tecnológica, com palavras-chave e combinações específicas, se deu nas seguintes bases: SciELO, PubMed, INPI, EPO, LATIPAT, USPTO e WIPO. Os resultados para as buscas de artigos e patentes revelaram, de forma geral, que pouco tem sido explorado acerca das atividades biológicas nematicida e larvicida da cafeína. Portanto, conclui-se que novos estudos com a cafeína, voltados para o controle de inimigos naturais de culturas, são promissores para o desenvolvimento de novas tecnologias agrícolas. </span></p><div><span><br /></span></div>
