Natural insecticide based-leaves extract of Piper aduncum (Piperaceae) in the control of stink bug brown soybean

Abstract

This research aimed to evaluate the insecticide potential of the leaves extract of Piper aduncum (L.) (Piperaceae) on development of brown stink bug, Euschistus heros (F.), major pest in soybean crop in Mato Grosso

Fur-rubbing withPiperleaves in the San Martín titi monkey,Callicebus oenanthe

“…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).…”

Potential phytoinsecticide of Annona mucosa (Jacq) (Annonaceae) in the control of brown stink bug

“…Although concentrations lower than 10mg.mL -1 do not reduced survival of adults, a significant reduction in fecundity and/or fertility of females was observed (Table 1), indicating a sublethal effect on physiological traits of E. heros, when treated with seeds extract of A. mucosa. The reduction in longevity and inhibition of oviposition of females of Pentatomidae are also reported in N. viridula, when treated with neem-based products containing compounds rich in azadirachtin (95%) (RIBA et al, 2003) and of E. heros, when treated with leaves extract of P. aduncum (PITON et al, 2014). We believe that the toxic effect of A. mucosa against nymphs and adults of E. heros, is likely associated with the presence of the bioactive compounds, such as acetogenins, however, in this research was used crude extract (miscellaneous of compounds), thus the possibility of synergistic action between compounds cannot be discarded, as suggested by Nerio et al (2010), therefore, further investigation is needed to confirm this hypothesis.…”

“…For the bioassay with nymphs, five 3 rd instar individuals were used per repetition (n=50 nymphs/treatment), and for the bioassay with adults, one pair of E. heros up to 24 hours old was used per repetition (n=20 adults/treatment). All bioassays were conducted following the methodology described by Piton et al (2014). The nymphs and adults were treated by topic application of lµL and 5µL treatments, respectively.…”

Quantitative and qualitative damage caused by Oebalus poecilus (Hemiptera, Pentatomidae) to upland rice cultivated in new agricultural frontier of the Amazon rainforest (Brazil)

“…Besides this information, the producer must consider several other factors already reported in the studies of Barrigossi (2008), Tindall, Stout and Williams (2004) and Tindall et al (2005) aimed at integrated pest management, in addition to the use of alternative controls such as the use of phyto-insecticides and release of natural enemies (Favetti et al, 2013;Massaroli, 2014;Machado, 2014;Piton et al, 2014;Zachrisson;Costa;Bernal, 2014;Zachrisson et al, 2014;Turchen et al, 2016ab;Foerster, 2016;Martins;Sanini et al, 2017).…”
