A new technique was develop to study the anomalous behavior of non parasitic phase of Anocentor nitens on horse host. From the total teleogines was still alive during all experimental period, 89.1% laided eggs on ear host. The eclosion index was 77.05% with 80.0% of eclodibility.The preoviposition period and oviposition period was 3 to 17 days (4.92±0.73 days) and 16 to 41 days (24.38±1.05 days), respectively. The incubation period was 26 to 48 days (34.94±2.92 days). It was confirmed that A. nilens teleogine could laid on ear of horse, when it was dettachment and a factor impossibilited it down on ground.
