Abstract

In the present study fenugreek nanoemulsion (FN) was tested against mosquitoes vector; so; characterization of this nanoemulsion using a transmission and scanning electron microscope (TEM and SEM). The used molecules appear to be spherical with a mean diameter of 80 nm. The larvae in the fourth stage were exposed to higher concentrations of FN from 10 to 320 μl/ml each for 1 and 2 hours of exposure time. The results proved that LC50 (lethal concentration) against mosquitoes 4th larval stage was 200 μl/ml/ for 2h and LC90 was 65 μl/ml / for 2 h while the positive control material (temephos) was 0.02 mg/L. As the two previous doses increased to 160 l/ml/2 h and 320 l/ml/2 h, Culex quinquefasciatus pupae showed a slightly high tolerance to the influence of these nano-emulsions. These findings suggest a new field for eradicating this vector (Culex quinquefasciatus) which can avoid the resistance that has been observed in previous chemical applications in this field. Nanotechnology rises up to give a wide scale for pest control and medicine.
