| Abstract: | The results of two methods of estimation of abundance of adult Ixodes persulcatus ticks, the absolute (at the sample plots) and the relative (per flag-hour) estimations, were compared. Collecting of ticks and estimation of their abundance was conducted during 9 years at the forests of the Far East and Pre-Ural region. The total of 1995 plots (100 sq. m each) were studied and 865 flag-hours were carried out. A good correlation of the data, obtained by these methods, was revealed. The average number of adult ticks, collected per flag-hour, approximately corresponds to the average number of ticks, activated during the season at 100 sq. m. The possibility of corresponding re-calculation of the results of estimation per flag-hour into the parameters of tick population density was evaluated. It was shown that such re-calculation gives good results. Their inexactitude usually doesn't exceed the statistical error of the parameters, obtained by the estimation of tick density at sample plots. |
