Toxicity of essential oils of Piper marginatum Jacq. against Tetranychus urticae Koch and Neoseiulus californicus (McGregor)

Abstract

95%). The P. marginatum oils also deterred oviposition. Among the chemical constituents tested, sesquiterpenes were more toxic with an LC50 of 2.89 μL L-1 than phenylpropanoids Z-asarone and E-asarone with LC50 6.64 and 8.51 μL L-1, respectively. The acaricidal properties, oviposition deterrence and selectivity make these oils strong candidates for use as the active ingredient in a plant-based acaricidal agent.]]>

“…This includes both internal and external (topical) use of leaf extracts, infusions and decoctions (Taylor, 2006). Constituents of P. aduncum, like dillapiole and other phenylpropanoids, are potent insecticides (Fazolin et al, 2014;Marques and Kaplan, 2015;Pino et al, 2011;Piton et al, 2014;Ribeiro et al, 2016;Vila et al, 2005;Volpe et al, 2015). Extracts of P. aduncum have also been shown to possess antifungal properties (Santos et al, 2013).…”

Acaricidal properties of essential oils from agro‐industrial waste products from citric fruit against Tetranychus urticae

“…T. urticae was reared at a temperature of 25 ± 1°C, relative humidity of 65 ± 5% and a 12-hr photoperiod and without any exposure to acaricides. The breeding method was adapted from Ribeiro, Camara, and Ramos (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

“…Piper aduncum and P. marginatum presented compounds already reported as insecticides in previous works, such as dillapiol, asaricine (sarisan), piperitone and myristicin (Bizzo et al, 2001;Morais et al, 2007;Qin, Huang, Li, Chen, & Peng, 2010;Souto et al, 2012;Santana et al, 2015;Ribeiro, Camara, & Ramos, 2016;Krinski & Foerster, 2016). For P. caldense, P. fuligineum, P. Mollicomum, and P. mosenii, there are no studies regarding the insecticidal activity, and our work is the first to test the ovicidal activity against a lepidopteran pest of importance in Brazilian agriculture.…”
