“…In evaluating the bioactivity of C. odorata, [23] found that its ALEs was very strongly positively correlated with the progeny production of S. zeamais and grain weight loss in maize. Insecticidal or acaricidal and antimicrobial agents including quercetin, gallic acid, flavone or kaempferol responsible for pest repellence, deterrence or toxicity have specifically been isolated from the R. communis plant [24,25]. Ingestion and contact of the oil emulsion (10%) of R. communis by P. xylostella larvae on cabbage resulted in 100% mortality, and also strongly deterred oviposition (<20 total eggs) 5 DAA [26].…”

“…Sorghum seeds treated with hydraulic and ethanolic seed extracts of R. communis (0.1 -0.5 ml/5g seed) repelled 80% of Tribolium castaneum Herbst adults and also caused 100% larval mortality 3 DAA [27]. Also, in killing 48% -60% diazinon, deltamethrin and multi-acaricide resistant cattle ticks, Rhipicephalus microplus, the leaf extract of R. communis proved to be considerably effective against organophosphate and pyrethroid resistant ticks [25]. Similar to our results, however, other studies have also found the extracts of R. communis to be slightly efficacious against certain insect pests.…”

Geo-climatic and socio-economic conditions provide a favourable environment for parasitic population of livestock in Pakistan. Hard ticks (Ixodidae) and gastrointestinal nematodes pose most serious threats to livestock industry. Stackholders rely on synthetic drugs to control these parasites. Emergence of drug resistance in these parasites; however, has provoked interest in alternate of synthetic drugs. Testing of plants used in ethnoveterinary medicine for their antiparasitic activity employing standard procedures has been reported to be promising. Plants have been most frequently used for deworming purposes followed by as acaricides and insecticides; whereas, reports as to their antiprotozoal use are relatively less. Use of plants as antiparasitics is more frequent in developing countries having low accessability to the modern parasite control practices. Likewise, validation studies on the use of plants as antiparasitics have been more frequently carried out in the developing countries compared with those having livestock farming as commercial enterprise. This article presents an overview of the plants having acaricidal and anthelmintic activity, limitations as to the application of phytotherpay to control parasites and future prospects of the use of plants as antiparasitics.

“…Nonetheless, other alternative methods to control this parasite have been attempted, among which, the use of phytochemical products stands out (Valente et al 2014). 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).…”

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

Larval packet test was used for detection of resistance status against cypermethrin and deltamethrin, the most commonly used synthetic pyrethroids in Rhipicephalus (Boophilus) microplus collected from Faridkot district, Punjab (India). The slope of mortality, lethal concentration for 50 % (LC50) and resistance levels were determined from the regression graphs of probit mortality of ticks plotted against log values of increasing concentrations of cypermethrin and deltamethrin. Results indicated presence of resistance of levels I and II against cypermethrin (resistance factor (RF) = 2.82) and deltamethrin (RF = 8.44), respectively. Adult immersion test was used to assess the acaricidal activity of aqueous (MLAq), ethanol (MLE), chloroform (MLC), acetone (MLA) and hexane (MLH) extracts of leaves of Murraya koenigii against these synthetic pyrethroid (SP)-resistant engorged adult females of R. (B.) microplus by determination of per cent adult mortality, reproductive index (RI), per cent inhibition of oviposition (%IO) and hatching rate. The per cent mortality caused by various extracts at concentrations ranging from 0.625 to 10.0% varied from 0.0 to 100.0% with maximum per cent mortality of 10.0, 100.0, 70.0, 40.0 and 10.0 recorded against MLAq, MLE, MLC, MLA and MLH, respectively. Among all extracts, the highest acaricidal property against SP-resistant R. (B.) microplus was exhibited by the MLE as it showed the minimum LC50 [95% confidence limit (CL)] values of 2.97% (2.82-3.12%), followed by MLC as 10.26% (8.84-11.91 %) and MLA as 18.22% (16.18-20.52%). The average egg mass weight recorded in live ticks treated with various concentrations of different extracts was lower than the respective control group ticks and was significantly (p < 0.01) lower in ticks treated with MLH extract. However, no significant effect on hatchability of eggs of treated groups when compared to control was recorded. A significant (p < 0.05) decrease in the RI was recorded in MLH extract-treated ticks, and the %IO varied from 0.07 to 34.73% with various extracts and was recorded maximum with highest concentration of MLH. The results of the current study indicate that the extracts of M. koenigii can be used for control of SP-resistant ticks.
