“…A utilização de inseticidas menos nocivos ao meio ambiente é uma alternativa sempre bem recebida. Nesse contexto é importante a informação de que plantas são ricas em substâncias do metabolismo secundário úteis no desenvolvimento de métodos seguros aplicados ao controle de insetos, desse modo, os aleloquímicos despontam como possíveis substitutos aos compostos sintéticos com eficiência e baixa toxicidade ao homem e ao meio ambiente (KNAAK & FIUZA 2010, SOUZA et al 2015.…”

“…Além dos resultados obtidos com os curculionídeos, outros trabalhos utilizando extratos de cinamomo contra diferentes insetos e ácaros veem sendo realizados (MIGLIORINI et al 2010MANZOOR et al 2011, KOSMA et al 2014, BUSATO et al 2015, SOUZA et al 2015, AKHTAR et al 2015) e é inegável a contribuição dos estudos nessa área para o aprimoramento do uso de produtos derivados de cinamomo.…”

RESUMOO presente estudo teve como objetivo testar a eficiência do extrato supercrítico de Melia azedarach no controle de Sitophilus zeamais por meio do contato tarsal. Observou-se a sobrevivência dos insetos a cada 24 h após o início do experimento. Constatou-se que houve maior mortalidade de insetos nas primeiras 72 h. O tratamento que teve melhor desempenho considerando-se a relação tempo de ação e número de insetos mortos foi o de concentração 200 μL mL -1 . A concentração letal média que mata 50% da população (CL50) obtida após 96 h do tratamento foi de 165,52 μL mL -1 , indicando que a maior dose pode ser reduzida com resultados satisfatórios para as condições empregadas no estudo. O extrato de M. azedarach revelou-se efetivo no controle de S. zeamais em condições de laboratório. ABSTRACTThis study aimed to test the efficiency of the Melia azedarach supercritical extract in controlling Sitophilus zeamais through tarsal contact. The survival of insects was observed every 24 h after the experiment started. A higher mortality of insects was found during the first 72 h. The treatment that had the best performance considering the action time and the number of dead insects was that at 200 μL mL-1 concentration. The mean lethal concentration that kills 50% of the population (LC50) obtained after 96 h treatment was 165.52 µL ml-1, showing that the higher dose can be reduced with satisfactory results for the conditions used in this study. The extract of M. azedarach was effective in controlling S. zeamais under laboratory conditions.

Plant-originated triterpenes are important insecticidal molecules. Research on the insecticidal activity of molecules from Meliaceae plants has always been a hotspot due to the molecules from this family showing a variety of insecticidal activities with diverse mechanisms of action. In this paper, we discussed 116 triterpenoid molecules with insecticidal activity from 22 plant species of five genera (Cipadessa, Entandrophragma, Guarea, Khaya, and Melia) in Meliaceae. In these genera, the insecticidal activities of plants from Entandrophragma and Melia have attracted substantial research attention in recent years. Specifically, the insecticidal activities of plants from Melia have been systemically studied for several decades. In total, the 116 insecticidal chemicals consisted of 34 ring-intact limonoids, 31 ring-seco limonoids, 48 rearranged limonoids, and 3 tetracyclic triterpenes. Furthermore, the 34 ring-intact limonoids included 29 trichilin-class chemicals, 3 azadirone-class chemicals, and 1 cedrelone-class and 1 havanensin-class limonoid. The 31 ring-seco limonoids consisted of 16 C-seco group chemicals, 8 B,D-seco group chemicals, 4 A,B-seco group chemicals, and 3 D-seco group chemicals. Furthermore, among the 48 rearranged limonoids, 46 were 2,30-linkage group chemicals and 2 were 10,11-linkage group chemicals. Specifically, the 46 chemicals belonging to the 2,30-linkage group could be subdivided into 24 mexicanolide-class chemicals and 22 phragmalin-class chemicals. Additionally, the three tetracyclic triterpenes were three protolimonoids. To sum up, 80 chemicals isolated from 19 plant species exhibited antifeedant activity toward 14 insect species; 18 chemicals isolated from 17 plant species exhibited poisonous activity toward 10 insect species; 16 chemicals isolated from 11 plant species possessed growth-regulatory activity toward 8 insect species. In particular, toosendanin was the most effective antifeedant and insect growth-regulatory agent. The antifeedant activity of toosendanin was significant. Owing to its high effect, toosendanin has been commercially applied. Three other molecules, 1,3-dicinnamoyl-11-hydroxymeliacarpin, 1-cinnamoyl-3-methacryl-11-hydroxymeliacarpin, and 1-cinnamoyl-3-acetyl-11-hydroxymeliacarpin, isolated from Meliaazedarach, exhibited a highly poisonous effect on Spodoptera littoralis; thus, they deserve further attention.
