This present job evaluate the efficient of three doses of neem’s extract for the control of the hyaline mite Polyphagotarsonemus latus Banks in the stevia’s crop. This experimental job takes place in the UPAO’S Second Campus, in the plots of entomology’s lab, where stevia plants spread through cuttings that were getting by fount plants. These transplanted in eighty bags of polyethylene. It uses four treatments with doses of 0.75, 0.5 and 0.25 ml/l and other without application distributed in four blocks with a Latin Square design. The evaluations included the damaged plants’ number, the nymphs’ number and adults of hyaline mite for plant. The percentage of correct mortality, the height of the plant, the diameter of the stem and the foliar area. Make the analysis of variance (ANVA) and the Duncan comparison proof for 5 percent to compare the treatments. The evaluations of percentage of correct mortality were evaluated through the Henderson-Tillton formula. The results show that the application of neem’s extract to the 0.75ml/l doses, twenty four hours later produce the best results, to present a higher percentage of correct mortality, less damaged plants’ number and the height, the diameter and the foliar area didn’t affect significantly.
