“…Thus, population-limiting property of any plant extract need to be evaluated to assess the efficacy of extracts. In the present study, the effects of A. squamosa seed extract on the future progeny of the exposed ticks were evaluated by estimating the reproductive index (Ghosh et al 2005), and the data revealed a significant (P<0.05) reduction in the egg-laying capacity of all the ticks exposed to different concentrations (3-8% concentration) of A. squamosa in comparison to the ticks of control group. Previously, Srivastava et al (2008) assessed the population-limiting potential of neem seed extract, and a significant reduction of 0.34% in the RI of the ticks treated with 8% concentration of the extract in comparison to the ticks of control group was recorded.…”

“…The live ticks from all the animals were weighed individually and kept in tick rearing tube for oviposition. The RI, alteration in the egg mass production (DO%), alteration in the weight of adult tick (DR%), and the percentage efficacy of the extract (E%) (Ghosh et al 2005) of ticks from all the groups of animals were calculated as follows:…”

In the search of developing herbal acaricides, eight medicinal plants were screened for their efficacy against Boophilus microplus, the widely distributed tick species in India. Of the seven extracts screened, the extracts prepared from the Annona squamosa seed showed very high level of efficacy (70.8%) after 24 h of treatment. The effect of treatment on oviposition of the survived ticks was also assessed, and a significant reduction (P < 0.05) in the reproductive index was noted in comparison to control. When efficacy of the in vitro optimized concentration of A. squamosa was compared with previously tested extract of Azadirachta indica in in vivo model, it was observed that the extracts prepared from A. indica is more efficacious than the extracts of A. squamosa. A comparable efficacy against B. microplus fed on animals treated with herbal extracts and commonly used synthetic acaricide was noted. The possibility of using the herbal extracts in IPM format for the management of ticks is discussed.

Efficacy of rBm86 against Rhipicephalus (Boophilus) microplus (IVRI-I line) and Hyalomma anatolicum anatolicum (IVRI-II line) infestations on bovine calves

et al. 2012

With an aim to evaluate the protective potentiality of rBm86 against Rhipicephalus (Boophilus) microplus Indian Veterinary Research Institute (IVRI)-I line and Hyalomma anatolicum anatolicum IVRI-II line infestations on crossbred (Bos indicus × Bos taurus) calves, 20 animals of 3 months of age were randomly divided in to four equal groups and maintained in tick-proof conditions. Animals of groups 1 and 2 were immunized with 2 ml of rBm86 (100 μg)-based vaccine (procured from Revetmex S.A. de C.V, Mexico City, Mexico) thrice at 30 days interval. Animals of groups 3 and 4 were kept as negative control and inoculated with PBS only. Each animal of group 1 and 3 was challenged with 7-day-old 50 unfed adults of H. anatolicum anatolicum (1:1, male and female), and each animal of groups 2 and 4 was challenged with 6-8-day-old R. (B.) microplus larvae obtained from 50 mg of eggs, on 17th day of the last immunization. The efficacy of rBm86 against tick infestations was determined as percentage reduction in number of adults dropped (DT%), engorged body weight (DR%), egg masses (DO%), and immunogen efficacy (E%). The calculated data were 11.8, 10.8, 15.0, and 25.1 %, respectively, for DT, DR, DO, and E% against H. anatolicum anatolicum infestation, while in the case of R. (B.) microplus infestation, the corresponding data were 6.4, 11.24, 40.7, and 44.5 %, respectively. The results indicated partial effectiveness of rBm86 antigen(s) in imparting protection against homologous and heterologous challenge infestations of Indian ticks. The results indicated identification of more effective antigen(s) for the development of vaccine against economically important tick species in India.

“…The application was done by cotton swab. The tick feeding bags were checked daily, and entomological data on mortality percentage, alteration in the egg mass production (DO%), alteration in the weight of adult ticks (DR%), and percentage efficacy of the extract (E%) were calculated as follows (Ghosh et al 2005 …”

Extracts were prepared from leaf, bark, and seed of Azadirachta indica, leaf and seed of Prunus persica, bark of Mangifera indica, and leaf of Psidium guajava and were evaluated against Boophilus microplus. Of the eight extracts screened, the extracts prepared from the A. indica seed showed very high level of efficacy (80%) after 5 h of treatment. Besides the immediate effect on adult ticks, the egg-laying properties of the survived ticks was also assessed, and a significant reduction (P < 0.01) in the reproductive index of ticks fed on animals treated with A. indica seed extracts was noted in comparison to control. The efficacy of the neem seed extracts was compared with the commonly used synthetic pyrethroids, and comparable efficacy against B. microplus fed on animals treated with neem seed extracts and acaricide treated was noted. The possibility of using the extracts in IPM format for the management of ticks is discussed.
