Comparative effects of Cymbopogon schoenanthus essential oil and piperitone on Callosobruchus maculatus development

Influence of essential oil fractionation by vacuum distillation on acaricidal activity against the cattle tick

“…The genus Cymbopogon, family Poaceae, comprises a group of about 40 tropical aromatic grasses. The essential oils from several species of this genus have demonstrated insecticidal and repellent activity (Kim et al 2004;Ketoh et al 2006;Samarasekera et al 2006). The citronella (Cymbopogon winterianus J.)…”

Insecticidal Constituents of Essential Oil Derived from <i>Zanthoxylum armatum</i> against Two Stored-Product Insects

“…This indicates that fumigant toxicity may be a major route of insecticidal activity of piperitone against L. serricorne, while the mode of action in T. castaneum is via contact toxicity. It also has been reported that piperitone possessed insecticidal activity against the third instar larvae of Spodoptera littoralis and the adults of Callosobruchus maculatus 35,36 . Moreover, 2-tridecanone presented strong contact toxicity against L. serricorne and T. castaneum, whereas no fumigant toxicity of 2-tridecanone was measured to the test insects.…”

Antimicrobial and antioxidant activities of Cymbopogon schoenanthus (L.) spreng. essential oil, growing in Illizi - Algeria

“…But it was less efficient against individuals developing inside the seeds than the crude oil. The high larvicidal activity observed on 5-day old larvae with the crude oil was probably due to other compounds, which can act on various target sites at insect level like monooxygenases or acetylcholinesterases (Ketoh et al, 2006). The antimicrobial activities have been mainly explained through the presence of oxygenated sesquiterpenes and monoterpenes.…”

“…Due to the numerous published articles about chemical composition of C. schoenantus essential oil, in this section the recent findings will be discussed. The essential oil of the Togolese C. schoenantus (Ketoh et al, 2005(Ketoh et al, , 2006Koba et al, 2004) is characterized with high content of piperitone (61.01 to 69.01%) and the 2-carene (16.48 to 23.4%). While same species cultivated in Burkina Faso was not very rich in piperitone (42%) and the 2-carene (8.2%), but there is a significant presence of elemol (6.2%) (Onadja et al, 2007).…”

“…Furthermore when tested against Callosobruchus maculatus, piperitone, isolated from C. schoenanthus, was more toxic by fumigation to adults with a IC 50 value of1.6 µL/L vs. 2.7 µL/L obtained with the crude extract (Ketoh et al, 2006;Bossou et al, 2015). Piperitone was also reported as a powerful repellent and antiappetent agent against ant of Crematogaster spp.…”
