“…Considering that the leaves of P. cachimboense are easily harvested, the species is a good candidate for bioactivity testing of its oils regarding pest control in its occurrence region (Krinski 2013;Krinski 2015;Krinski et al 2015;Krinski and Foerster 2017), as already known for other Piperaceae species (Krinski and Foerster 2016;Turchen et al 2016;Sanini et al 2017). …”

Piper cachimboense is recorded only for the Amazon region of Brazil and Colombia, and the objective of this study was to report the first phytochemical assessment of the composition of the essential oils (EOs) from this species collected in the Amazon rainforest, in Novo Progresso, Pará State, Brazil. Samples of leaves were subjected to hydrodistillation in a Clevenger-type apparatus. The chemical identification was carried out by gas chromatography. The yield of oils was of 11.03 ± 5.94% for fresh leaves, and 1.07 ± 0.27% for dry leaves. The analysis showed 36 volatile compounds from fresh leaves and 49 from dried leaves. Main constituents in EOs of both fresh and dried leaves from P. cachimboense were (E)-caryophyllene, germacrene-D, γ-amorfene, δ-cadinene and apiole. RESUMOPiper cachimboense é registrada apenas para a região amazônica do Brasil e Colômbia, e o objetivo deste estudo foi relatar, pela primeira vez, a composição fitoquímica dos óleos essenciais (OEs) desta espécie coletada na floresta amazônica, em Novo Progresso/PA, Brasil. Amostras de folhas foram submetidas a hidrodestilação em aparelho tipo Clevenger. A identificação química foi realizada por cromatografia gasosa e o rendimento dos óleos foi de 11,03 ± 5,94% para as folhas frescas e de 1,07 ± 0,27% para as folhas secas. A análise mostrou 36 compostos voláteis para folhas frescas e 49 para folhas secas. Os constituintes principais dos OEs de folhas frescas e secas de P. cachimboense foram (E)-cariofileno, germacreno-D, γ-amorfeno, δ-cadineno e apiol. PALAVRAS-CHAVE

“…Some research evaluated the ovicidal and nymphicidal effects from different plants and pyrethroids on stink bug eggs of the Reduviidae and Pentatomidae families (Carneiro;Pereira;Galbiati, 2011;Krinski;Massaroli, 2014;Krinski;Machado, 2014;Laurent et al 1997;Rodrigues et al 2002). Besides the use of EOs, some studies also reported the ovicidal activity of algae and plant extracts (Piton et al 2014;Sahayaraj;Kalidas, 2011).…”

“…However, field and semi-field studies must be done in order to verify if the same pattern of results obtained in laboratory studies are maintained in the field both for T. limbativentris and for other insect pests found in rice and other food crops (Albuquerque, 1993;Krinski;Pelissari, 2012;Krinski;Butnariu, 2012;Krinski, 2013;Krinski;Grazia, 2015). We observed that the EOs that caused a larger percentage of inhibition of hatching nymphs of T. limbativentris were extracted from P. marginatum, a species that is not well known phytochemically.…”

“…Nonetheless, more studies should be conducted to compare the effect of oils obtained from other plant parts, including inflorescences and branches (stems) from the Piper species used in this study as well as other species with a wide geographical distribution (Fazolin et al, 2007;Ghosh et al, 2014;Lima et al, 2009;Parmar et al, 1997;Santos et al, 2010), to verify whether this ovicidal pattern remains constant. In addition, bioassays should be conducted to test the effect of various EOs on egg parasitoids of insect pests (Favetti et al, 2013;Krinski;Pelissari, 2012;Krinski;Butnariu, 2012;Krinski, 2013;Turchen et al, 2015;Zachrisson;Bernal, 2014;Zachrisson et al, 2014), since research to verify the selectivity of extracts or EOs of plants on natural enemies are scarce and almost non-existent (Turchen et al, 2014).…”

“…The rice stalk stink bug, Tibraca limbativentris Stål, occurs in all rice-growing regions of Latin America, where it is an important pest causing significant losses during the pre-flowering and grain filling stages (Krinski;Foerster, 2016). The occurrence of this pest has increased due to greater crop acreage, and favorable climatic and agronomic practices Grützmacher;Cunha, 2004;Rampelotti et al, 2007).…”

Tibraca limbativentris to is an important rice pest and occurs in all rice-growing regions of Latin America. The control this insect is accomplished with synthetic chemical insecticides, however, new approaches are needed to reduce risks to the environment, to the natural enemies and also to avoid the onset of insecticides resistance. This study was designed to assess the toxicity of essential oils (EOs) from leaves of Piper aduncum, P. gaudichaudianum, P. malacophyllum, P. marginatum and P. tuberculatum (Piperaceae) on rice stalk stink bug eggs, T. limbativentris. Essential oils were extracted with steam distillation and dilutions were made for bioassays at concentrations of 0.25; 0.5; 1.0; 2.0 and 4.0%. Essential oils from all species of Piperaceae displayed ovicidal activity. The LC 50 values indicated that both younger and older eggs were susceptible to these oils. Ovicidal activity is related to the potential toxicity of several compounds, especially dilapiolle, myristicin, cubebene, α-guaiene, longifolene, prezizane, spathulenol, sabinene and δ-2-carene. Thus, EOs tested showed promising results for use as biorational botanical insecticides. Index terms: Piper aduncum; Piper gaudichaudianum; Piper malacophyllum; Piper marginatum; Piper tuberculatum. RESUMOTibraca limbativentris é uma importante praga do arroz e ocorre em todas as regiões de cultivo de arroz da América Latina. O controle destes inseto é realizado com inseticidas químicos sintéticos, no entanto, novas abordagens são necessárias para reduzir os riscos para o ambiente, inimigos naturais, e também para evitar o aparecimento da resistência aos inseticidas. Este estudo foi concebido para avaliar a toxicidade dos óleos essenciais (OEs) das folhas de Piper aduncum, P. gaudichaudianum, P. malacophyllum, P. marginatum e P. tuberculatum (Piperaceae) sobre ovos do percevejo do colmo do arroz, T. limbativentris. Os OEs foram extraídos por arraste de vapor d´agua e a partir destes foram feitas diluições nas concentrações de 0,25; 0,5; 1,0; 2,0 e 4,0% para os bioensaios. Os OEs de todas as espécies de Piperaceae apresentaram atividade ovicida. Os valores de CL 50 indicaram que tanto os ovos mais jovens quantos os mais velhos foram suscetíveis aos diferentes óleos. Esta atividade ovicida pode estar relacionada com a toxicidade dos vários compostos encontrados em cada OE, como o dilapiol, miristicina, cubebeno, α-guaieno, longifoleno, prezizano, espatulenol, sabineno e δ-2-careno. Assim, os OEs testados mostraram resultados promissores para serem utilizados como inseticidas vegetais.
