Impact of Patch Diversity in Pinus massoniana on Population of Monochamus alternatus
摘要
Abstract
Pine wilt disease is a highly significant quarantine pest in China's forestry sector,characterized by its rapid spread and severe damage.The pine sawyer beetle(Monochamus alternatus),as its primary vector insect,serves as a crucial carrier for natural transmission.Consequently,the distribution and spread of this disease are also influenced by patches and landscape patterns.To clarify the effects of spatial landscape patterns and diversity on M.alternatus populations,the principles and methods of landscape ecology were applied,the influence of the spatial pattern and diversity of Pinus massoniana patches in a specific region on the population quantity of M.alternatus was analyzed.The results indicated that there was a significant correlation between the population quantity of M.alternatus and the pattern of P.massoniana patches.In the scattered P.massoniana forest patches in Songzi city,Hubei province,the population quantity of M.alternatus was significantly correlated with the patch area,perimeter and shape index of the patches,with correlation coefficients of 0.555,0.554 and 0.633,respectively.The population quantity of M.alternatus was significantly correlated with the relative abundance and ecological dominance of P.massoniana,with correlation coefficients of 0.909 and 0.881,respectively.The analysis results of species diversity within the patches suggested that the diversity of the shrub layer was significantly negatively correlated with the numbers of eclosion holes and trapped of M.alternatus within the patches,with correlation coefficients of-0.534 and-0.545,and the numbers of eclosion holes and trapped of M.alternatus within the patches was significantly negatively correlated with the overall diversity of the patches,with correlation coefficients of-0.403 and-0.409.Therefore,the proactively adjusting the patches of P.massoniana forests to control the population of M.alternatus,thereby effectively suppressing the spread of pine wilt disease.关键词
