| Abstract | ||||
| Four pesticides (thiacloprid, etofenprox, spirotetramat and fenbutatin oxide) were evaluated against the adults of chocolate banded snail, Eobania vermiculata under laboratory conditions. Two types of pesticide formulations were used; conventional formulations (suspension concentrate and emulsifier concentrate) and nanoformulations (nanoparticles). The size of nanoparticles in tested pesticides ranged between 145 to 587 nm. The obtained results showed that the conventional formulations were more effective than the nanoformulations in all tested pesticides except etofenprox. The efficacy of etofenprox as a conventional formulation was approximately the same in nanoformulation in all concentrations used. The percentage of mortality were 86.7, 66.7 and 46.7; and 81.7, 55.0 and 35.0% with conventional and nanoformulations, respectively. The LC50’s in etofenprox conventional and nanoformulations were 14.9 and 20.3 ppm, respectively. This result showed that etofenprox can be used as an effective nanoparticle pesticide against the adults of chocolate banded snail, E. vermiculata. This means that one fifth of etofenprox concentration in nanoformulation was effective as conventional formulation. So, it can be reduced the pesticides hazard on nontarget organisms and reduced the pesticide cost. | ||||
