Chemical composition, oviposition deterrent and larvicidal activities against Aedes aegypti of essential oils from Piper marginatum Jacq. (Piperaceae)

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

“…The compounds for investigation of acaricidal potential were selected based on the chemical identification of P. marginatum oils determined previously by our research group (Autran et al, 2009) (Table 1) and their commercial availability. Compounds with a high degree of purity (97% to 99%) were acquired commercially from Sigma (St. Louis, Missouri, USA), together with eugenol, which was used as the positive control.…”

“…The acaricidal properties, oviposition deterrence and selectivity make these oils strong candidates for use as the active ingredient in a plant-based acaricidal agent. the mosquito Aedes aegypti and also serve as a deterrent to oviposition (Autran et al, 2009). The insecticidal activity of P. marginatum oil has been reported for other arthropods, such as Solenopsis saevissima (Souto et al, 2012), Tenebrio molitor (Fazolin et al, 2007), Sitophilus zeamais (Estrela et al, 2006;Coitinho et al, 2011), Tyrophagus putrescentiae and Suidasia pontifica (Assis et al, 2011).…”

Chemical composition of essential oils of Piper jacquemontianum and Piper variabile from Guatemala and bioactivity of the dichloromethane and methanol extracts

“…No activity was demonstrated against insect larvae as well as against A. salina nauplii. Other species have shown larvicidal activity against A. aegypti, such as P. fimbriulatum (Solis et al, 2005) and P. marginatum (Autran et al, 2009).…”

Bioactivity of seagrass against the dengue fever mosquito Aedes aegypti larvae

“…Various synthetic products and devices have been designed to combat resistance developed by various mosquito species. Most of the mosquito control programmes target the larval stage in their breeding sites, while adulticides may only reduce the adult population temporarily [2,3] . The chemicals derived from plants have been projected as weapons in future mosquito control programme as they are shown to function as general toxicant, growth and reproductive inhibitors, repllents and oviposition-deterrent [4] .…”
