| Abstract: | A study was conducted to forecast the occurrence level of Dendrolimus punctatus during 2003-2005 by means of Markov chains based on the historical data of occurrence degree of D. punctatus from 1975 to 2002 in Yunan, Guangdong Province. The forecast accuracy of occurrence level from 1990 to 2002 was 92.31%. |
