Essential oil of spiked pepper, Piper aduncum L. (Piperaceae), for the control of caterpillar soybean looper, Chrysodeixis includens Walker (Lepidoptera: Noctuidae)

Abstract

The resistance of pests to insecticides and the high costs of pest control have prompted a search for less harmful alternatives to the environment. Phytoinsecticides can be a promising option in the control of pests. The insecticidal properties of the essential oil of Piper aduncum L. (Piperaceae) have been demonstrated by several authors. This study was aimed at evaluating the insecticidal activity of P. aduncum essential oil on caterpillars of the soybean looper, Chrysodeixis includens Walker. Two bioassays were conducted: The first was based on the ingestion of treated leaves, while the second, on direct contact. Chromatography was performed, and the resulting oil was used to treat larvae fed cotton leaves at the concentrations of 0.5, 1.0, 2.0, 4.0, and 8.0%. The controls consisted of water and acetone. The first assessment was carried out 24 h after the application. The main compounds identified by chromatography were dillapiole, myristicin, and Z-carpacin. In the ingestion bioassay, mortality reached 90% for the highest concentration in the first 24 h after application. For the topical application of P. aduncum essential oil, no significant differences were observed until the end of the life cycle of C. includens. This study demonstrates the insecticidal activity essential oil of P. aduncum on C. includens and its potential in the control of this insect by ingestion.

Phytochemical of Piper essential oil and acute toxicity against Helicoverpa armigera (Lepidoptera: Noctuidae)

“…Piper genus essential oil has exhibited promising results in pest control, because of active compounds, as terpenoid and phenylpropanoid that are broadly knowledge by toxicity on arthropods pest (Fazolin et al, 2007;Scott et al, 2007;Boulogne et al, 2012;Regnault-Roger et al, 2012), included to lepidopterans pest (Lima et al, 2009;Sanini et al, 2017). In addition, these compounds has been reported by exhibit low toxicity on egg parasitoids, which makes possible integrate with biological control (Turchen et al, 2016).…”

<b>Ovicidal effect of the essential oils from 18 Brazilian <i>Piper</i> species: controlling <i>Anticarsia gemmatalis</i> (Lepidoptera, Erebidae) at the initial stage of development

“…It was shown that the chemical compounds present in these Piperaceae can be further evaluated among the isolation of active molecules to develop new botanical formulations, especially when we consider that the majority of these substances has been reported as potential insecticides in many other studies conducted worldwide (Santos et al, 2010;2013;Cáceres & Kato, 2014, Brito, Baldin, Silva, Ribeiro, & Vendramim, 2015Krinski & Foerster, 2016, Sanini et al 2017, Turchen, Hunhoff, Paulo,Souza, Pereira, 2016b and other plant families (Isman, 2000;Koul, Walia, & Dhaliwal, 2008;Tripathi, Upadhyay, Bhuiyan, & Bhattacharya, 2009;Coitinho, Oliveira, Gondim-Júnior, & Câmara, 2010;Ntalli & Menkissoglu-Spiroudi, 2011, Zoubiri & Baaliouamer, 2011Baskar, Muthu, Raj, Kingsley, & Ignacimuthu, 2012;Krishnappa & Elumalai, 2012;Cáceres & Kato, 2014Krinski, Massaroli, & Machado, 2014;Backiyaraj et al, 2015;Massaroli, Pereira, & Foerster;Costa, Santana, Oliveira, & Serrão, 2017).…”

First phytochemical description of essential oils from Piper cachimboense (Piperales, Piperaceae)

“…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). …”
