Summary: | Nanosizing antiparasitic formulation has tremendous potential to control parasite infection by rectifying drawbacks of conventional formulations. The present study investigates synthesis optimization of cypermethrin nanoemulsion using PEG diblock copolymers through a spontaneous emulsification technique. Synthesis parameters of nanoemulsion were optimized using response surface methodology with central composite design to get nanoemulsion (NEC-1) with lowest particle size (179.8 nm) and highest encapsulation efficiency (90.24%). TEM and DLS revealed the spherical morphology and negative zeta potential (− 42.4–57.2 mV) of the developed nanoemulsion formulations. Bioefficacy of the NEC-1 was studied against fish ectoparasite
Argulus bengalensis
at embryonic and adult stages. It was observed that treatment of nanoemulsion disrupted the natural developmental stage of
A. bengalensis
egg at a very low concentration (0.001 ppm). The calculated LC
50
against the adult parasite and LC
50
for prevention of 50% egg hatching was found to be 0.005 and 0.006 ppm, respectively. In the recent scenario of repetitive antiparasitic resistance, the developed nanoemulsion could come out as a potential solution; however, further study is required for its feasibility for use in actual field conditions. |
