On the basis of above experimental data, it can be conclusively
noticed that the larvae of F. gigantica inside the body of vector
snail L. acuminata can be killed by citral, ferulic acid, umbelliferone,
azadirachtin and allicin. Amongst all azadirachtin and allicin
caused maximum inhibition in AChE and cytochrome oxidase in
cercaria There is no adverse effect of these active cercaricides on
the vector snails, as AChE activity in treated snail’s nervous tissues
was not significantly altered. As a corollary, it is suggested that sublethal phytotherapy of snail by these cercaricides is effective toolfor the control of larvae of Fasciola, and ultimately fasciolosis, is
ecologically sound, target specific and economical.
