Evaluation on Control Ability of Elaeagnus angustifolia to Anoplophora glabripennis in Mixed Forest Mainly Consist of Poplar
摘要
Abstract
[Objective]To evaluate the control ability of Elaeagnus angustifolia L.to Anoplophora glabripen-nis(Asian Longhorned Beetle,ALB)in mixed forest stands.[Method]We investigated each tree in three different types of mixed forest,recorded relative infestation indices,and compared the ALB infestation of different tree species in various forest stands.[Result]1)In mixed forest belt Ⅰ(control)where only two poplar species,P.alba var.pyramidalis and P.deltoides'Shalinyang',were planted,no significant differ-ences in ALB infestation were observed between the two species.In mixed forest belt Ⅱ,which included the same two poplar species along with Elaeagnus angustifolia L.and Populus×xiaohei var.gansuensis,the latter species were severely infested.In mixed forest belt Ⅲ,consisting of E.angustifolia,P.alba var.pyramidalis and P.deltoides'Shalinyang',P.deltoides'Shalinyang'exhibited higher infestation levels com-pared to the other two species.;2)P.alba var.pyramidalis is the main tree species for farmland shelter-belt construction.The ALB infestations of P.alba var.pyramidalis in mixed forest Ⅱ and Ⅲ were slightly lower than in the belt I,but the difference was not significant.Both P.deltoides'Shalinyang'and P.×xiao-heivar.gansuensis were more heavily infested than P.alba var.pyramidalisin mixed forest belt Ⅱ,with P.×xiaohei var.gansuensis showing the most severe infestation.[Conclusion]E.angustifolia did not signific-antly affect ALB infestation on P.alba var.pyramidalis.Among the species studied,P.×xiaohei var.gan-suensis was the most severely infested,and thus appears to be the primary host for ALB in the mixed forest.Since it was seriously infested,it could act as a source of ALB spreading.Therefore,we do not re-commend planting P.×xiaohei var.gansuensis in mixed protection forests.关键词
