[Effect of the urea fertilization in pasture on Rhipicephalus (Boophilus) microplus (Acari: Ixodidae)].
The objective of this study was to verify the effect of the urea fertilization in pasture on Rhipicephalus (Boophilus) microplus population in free living stage. Two groups had been made, a control group and a urea treatment group, each group with 10 lots of Mombaça grass (Panicum maximum cv. Mombaça). In day zero had been placed 12 engorged tick females in each lot and made fertilization with urea in the dosage of 60 g in the lots of the treat group. In 27th day the grass was cutted out in 1 to 5 lots of both groups and fertilized with urea in the lots of 1 to 5 in the treat group. In 40th day was released a white flannel 1.60 x 1.00 m length on each lot to verify the presence of larvae. The results presented a difference of 85.97% (P < 0.0001) between the treat group and the control group.
