“…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).…”

“…Similarly, Zahir et al(2009) have reported that the parasite mortality was found in the leaf ethyl acetate extract of Achyranthes aspera, leaf methanol extract of A. malabarica, flower methanol extract of G. superba, and leaf methanol extract of R. communis against the larvae of Rhipicephalus microplus (LC 50 =265.33,95.97,153.73,and 181.49 ppm;LC 90 =1,130.18,393.88,1,794.25,and 1,829.94 ppm); leaf acetone and chloroform of A. malabarica, flower acetone Control-nil mortality.

In the current study, in vitro evaluation of crude hexane, chloroform, ethyl acetate, acetone, and methanol extracts of Anisomeles malabarica (L.) R. Br., Gloriosa superba L., Psidium guajava L., Ricinus communis L., and Solanum trilobatum L. exhibited acaricidal and insecticidal activities against the adult of Haemaphysalis bispinosa Neumann (Acarina: Ixodidae) and hematophagous fly Hippobosca maculata Leach (Diptera: Hippoboscidae). All plant extracts showed moderate toxic effect on parasites after 24 h of exposure; the complete inhibition (100%) at the maximum concentration tested (3,000 ppm) was obtained in acetone, methanol, hexane, and chloroform extracts of A. malabarica; methanol, chloroform, and ethyl acetate extracts of G. superba; acetone extract of P. guajava; methanol extract of R. communis; and leaf hexane extract of S. trilobatum; and the lowest inhibition (38%) was recorded for the seed hexane extract of S. trilobatum. The highest parasite dead was found in leaf acetone and methanol extracts of A. malabarica, seed methanol of G. superba, leaf methanol of R. communis against H. bispinosa (LC(50) = 466.15, 719.78, 476.06, and 243.87 ppm; LC(90) = 1,837.96, 2,014.47, 1,904.36, and 2,692.15 ppm), leaf hexane and chloroform extracts of A. malabarica, seed chloroform and ethyl acetate of G. superba, leaf acetone of P. guajava, leaf methanol of R. communis, and leaf hexane extract of S. trilobatum against H. maculata (LC(50) = 495.61, 414.81, 360.02, 479.37, 646.30, 506.13, and 432.77 ppm; LC(90) = 1,914.84, 1,956.59, 1,598.54, 1,636.41, 2,192.73, 1,982.66, and 1,872.33 ppm), respectively. These results suggest that the leaf methanol of R. communis, chloroform extracts of A. malabarica, and chloroform extract of G. superba have the potential to be used as an ideal eco-friendly approach for the control of the H. bispinosa and H. maculata. Therefore, this study provides first report on the parasitic activities of plant extracts from Southern India.

The objective of this work was to evaluate the effect of a 5% neem extract on the presence of ticks. Forty creole cattle were used, divided into four groups: 2 experimental and 2 controls, in the towns of Cocula and El Chante, Jalisco. The tick count was by direct palpation, and with an acarometer (25 cm 2). Eight body regions were evaluated: neck, thorax, flank and thigh, left and right. At zero time, after the initial tick count, it was applied by spraying and once, the 5% neem extract, at a dose of 10 ml/L. Ticks were quantified at 7, 14, 21, 28, 35 and 42 days post-treatment. The data were subjected to descriptive statistical analysis and Sum of Kruskal-Wallis Ranges (α = 0.05) (Sig-maStat 3.1). In Cocula, at zero time, the average of ticks was in neck 32, in thorax 64, in flanks 96 and in thighs 129 (average per animal 323 ticks). In subsequent sampling, the average decreased in the experimental group to 1 or 4 parasites. In "El Chante", an average of 60 ticks was found at the time of the neck, in the thorax 121, in flanks 181 and in thighs 242 (average per animal 600 ticks). In subsequent sampling, the average decreased in the experimental group, with averages of 1 to 4. Statistical differences (p ≤ 0.001) were found between the groups. It can be concluded that 5% neem extract has a repellent and tick effect in cattle for at least 42 days.
