Adaptability Analysis of American White Moth in the Mount Tai

With American white moth continuously spread in Shandong province,it’s occurrence,prevention and control at the Taishan(Mount Tai),a world natural heritage,cultural heritage,world geological park,the National Civilized and Scenic Area,and the national 5A-class tourist spot,was much concerned.This study mainly analyzed adaptability of American white moth at different altitudes based on the meteorological data of different stations from 2001 to 2009 in the Taishan Scenic Area.The results showed that weather conditions at different altitudes of Taishan Scenic Area were suitable for American white moth growth.At the peak of 1 553.0 m above sea level,the pest could complete one generation in a year.At the low and middle altitude,it completed 2-3 generations,or 1-2 generations in a year.Combined with host ecological distribution and producing eggs characters of the American white moth,we predict that the pest would bring great risk and harm once it enters to the Scenic Areas.It is very urgent and necessary to strengthen the risk management of the Taishan Scenic Area,and to establish a sound early warning and monitoring system for the pest occurrence.
