Acaricidal activity of Cassia alata against Rhipicephalus (Boophilus) annulatus

Abstract

Using adult immersion test, the acaricidal activity of ethanolic extracts of leaves of Cassia alata L. was studied against Rhipicephalus (Boophilus) annulatus. The efficacy was assessed by measuring per cent adult mortality, inhibition of fecundity and hatching rate. The ethanolic extract of C. alata produced a concentration dependant increase in the adult tick mortality. The highest mortality (45.8%) and inhibition of fecundity (10.9%) were observed at the highest concentration tested (100 mg/ml). The plant extract did not affect egg hatchability.

In vitro acaricidal properties of Semecarpus anacardium fruit and Datura stramonium leaf extracts against acaricide susceptible (IVRI-I line) and resistant (IVRI-V line) Rhipicephalus (Boophilus) microplus

“…microplus ticks and the former plant was found effective to inhibit tick population and reproductive potential significantly. Similar attempts were made earlier to identify acaricidal / insecticidal potentiality of different medicinal plants against muscid flies (Palacios et al, 2009a;2009b), Culicoides (Narladkar et al, 2006), lice (Davidović et al, 2012), mites (Kim et al, 2004;Magi et al, 2006), ticks (Broglio-Micheletti et al, 2009;Ravindran et al, 2012;Ghosh et al, 2013, Shyma et al, 2014 and microorganisms/parasites (ICMR, 2008). It is obvious that naturally occurring phyto-chemicals possess a number of active components which interfere with different biological activities of the insects interrupting their normal life cycle and are safer to non-targeted organisms and easily biodegradable (Habeeb, 2010;Zaman et al, 2012).…”

Acaricidal activity of ethanolic extracts of Stryphnodendron adstringens and Lafoensia pacari and oil resins from Copaifera sp. and Pterodon emarginatus against Sarcoptes scabiei var. suis

“…In general, topical scabicidal act by neurotoxicity, but can act by asphyxiation (Archer et al 2014) once mite respiration occurs through tegument once the absence of a tracheal system (Evans 1992). Little is known about the action mode of many plants materials, but the beneficial effects result from single or combinations of active compounds present in the plant (Ravindran et al 2012).…”

In vitro acaricidal activity of Murraya koenigii (L.) Spreng (Rutaceae) extracts against synthetic pyrethroid-resistant Rhipicephalus (Boophilus) microplus

“…These phytochemical products may also be beneficial as acaricides because of the increasing demand for pesticide-free products by consumers and the growing resistance (Fernandez-Salas et al 2011;Ghosh et al 2013). Recently, various plant extracts and essential oils have shown significant activity against all the stages of economically important tick species (Borges et al 2003;Ribeiro et al 2008Ribeiro et al , 2010Ribeiro et al , 2011Magadum et al 2009;Ravindran et al 2011Ravindran et al , 2012Ghosh et al 2013;Godara et al 2014). Further, plants with known biological activity such as M. koenigii merit research to explore it as an alternative for the control of parasitic diseases and a potential source of new active ingredients.…”

“…Among the various plant products explored for acaricidal activity, extracts and essential oils have shown significant effects against various stages of economically important tick species (Borges et al 2003;Ribeiro et al 2008Ribeiro et al , 2010Ribeiro et al , 2011Magadum et al 2009;Ravindran et al 2011Ravindran et al , 2012Ghosh et al 2011Ghosh et al , 2013Godara et al 2014).…”
