“…The reduction in adult tick weight (DR%) has been recorded as 22.2%, 13.3%, 15.5% in groups II, III, and IV, respectively. In case of group II (CT), the reduction in adult tick weight may be due to the direct effect of the cypermethrin because it exerts primary action by targeting kinetics of sodium channels in nerve (Hart 1986). This action results in either repetitive discharge or membrane depolarization and subsequent death of target insect.…”

Comparative efficacy of Annona squamosa and Azadirachta indica extracts against Boophilus microplus Izatnagar isolate

2009

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.

“…The reduction in adult tick weight (DR%) has been recorded as 38.0% and 28.06% in groups II and III, respectively. In case of group II (cypermethrin), the reduction in adult tick weight may be due to the direct effect of cypermethrin because it exerted primarily by modulating gating kinetics of sodium channels in the nerve (Hart 1986). This action results in either repetitive discharge or membrane depolarization and subsequent death of target insect.…”

Efficacy of Azadirachta indica extracts against Boophilus microplus

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.
