“…A leaf-dipping method (Park et al, 2002) was used to evaluate the activity of the test samples. For adulticidal of the samples against A. craccivora and T. urticae, disks (5.4 cm diameter) of kidney bean (Phaseolus vulgaris L.) leaves (two weeks after germination) were used.…”

94) as main parts. The bioactive phytochemicals from F. sycomorus leaves were reported to be more toxic as the fumigant toxicity tests than the contact phase to the tested insects. The concentrations at 0.1, 0.01 and 0.001% were found to be repellent to adult females of Tetranychus utricae, followed by Aphis craccivora and Sitophilus oryzae, respectively. Here we demonstrate that bioactive phytochemicals from F. sycomorus leaves have a wide range of insecticidal and acaricidal and could become an alternative to synthetic pesticides for controlling certain important insects and mites.

(Piperaceae) are mainly comprised of phenylpropanoid dillapiol, a group of substances widely known by their insecticide and synergistic properties. The abundance of P. aduncum in the state of Acre, and the need to control the bean leaf beetle, Cerotoma tingomarianus Bechyné motivated this study, which examined the toxic effects of P. aduncum oil on these beetles. Mortality rate, survival and foliar consumption were used to evaluate the effects of topical (LD 50 and LT 50 ) and contact (filter-paper) (LC 50 ) applications of different oil concentrations. The toxicity of P. aduncum oil to C. tingomarianus was high with: LC 50 of 0.06 ml/ cm 2 and LD 50 of 0.002 ml/mg of the insect. For contact (filter-paper) applications, the mortality rate was nearly 100% at oil concentrations of 1%, whereas for topical applications, the mortality rate changed from 5% to 30%. Oil concentrations of 2.5% and 5% significantly reduced the foliar consumption by the beetles. Oil concentrations above 5% greatly reduced the LT 50 . Contact application (filter-paper) of P. aduncum oils have, therefore, insecticide effects on C. tingomarianus, when applied at 0,04 % concentration. In case of topical application, these oils can cause physiological problems, when used at concentrations higher than 2.5%.KEY WORDS: Dillapiol, essential oil, botanical insecticide RESUMO -No óleo essencial de Piper aduncum L. (Piperaceae) predomina o fenilpropanóide dilapiol, com reconhecida ação inseticida e sinergista. A abundância dessa piperácea no Acre e a necessidade do controle de Cerotoma tingomarianus Bechyné estimularam a realização desta pesquisa com o objetivo de avaliar a toxicidade do óleo essencial de P. aduncum sobre adultos da praga. Avaliou-se o efeito da aplicação de contato tópica (DL 50 e TL 50 ) e da ação por contato com superfície contaminada (papel-filtro) (CL 50 ) de diferentes concentrações do óleo, por meio da mortalidade e consumo foliar do inseto. Verificou-se que a toxicidade do óleo de P. aduncum para C. tingomarianus foi alta, considerando-se a CL 50 = 0,06 ml de óleo/ cm 2 e DL 50 = 0,002 ml de óleo/ mg de inseto. A mortalidade dos insetos alcançou praticamente 100% nas concentrações de 1% do óleo na avaliação por contato (papel-filtro) e de 5% a 30% nas concentrações aplicadas topicamente. Houve redução significativa do consumo foliar dos insetos nas concentrações de 2,5% e 5%, além da redução do TL 50 em função do aumento das concentrações. O óleo de P. aduncum apresenta efeito inseticida para C. tingomarianus na concentração de 0,04% por contato (papel-filtro), provocando ainda distúrbios fisiológicos pela ação da aplicação tópica em concentrações superiore...

The phytochemistry of the genus Piper (Piperaceae) has been widely studied due to the biological properties of amides from these plants. In this work, we have synthesized and evaluated the toxic effect of 11 amides against the fall armyworm Spodoptera frugiperda larvae. The naturally occurring piperine was also evaluated. The most active amide was N-[3-(3Ј,4Ј-methylenedioxyphenyl)-2-(E)-propenoyl]piperidine with a LD 50 of 1.07 µg mg Ð1 larvae. This amide was also evaluated by ingestion.
