不同物理阻隔器对沟眶象和臭椿沟眶象防治效果及生态位的影响
Different Physical Barriers on the Control and Ecological Niche of Eucryptorrhynchus scrobiculatus and E.brandti
摘要
Abstract
Eucryptorrhynchus scrobiculatus Motschulsky and E.brandti(Harold)are dangerous borer pests of the indigenous tree species Ailanthus altissima in China,which have brought devastating damage to A.altissima.Physical barrier capture is an important technical measure for the control of two species of weevil adults,mainly including hemline type barrier,trunk trap net,hat type barrier.At present,the ecological niche characteristics of two weevil adults under three physical barriers have not yet been clarified.Therefore,we investigated the diurnal activity and spatial distribution of two weevil adults under three physical barrier devices,and evaluated the control effect of the three barriers against two weevils by the marker recapture method.The results showed that both weevil adults were mainly active in the time period of 7:00-10:59.Three barrier devices all affected the spatial distribution and interspecific competition of two weevil adults on the A.altissima tree,and the spatial niche overlap values of the two weevils under natural conditions,hemline type barrier,trunk trap net,hat type barrier are 0.86±0.11,0.85±0.10,0.78±0.07,and 0.92±0.03,respectively.The trunk trap net and hat type barrier had the best control effect on the adults of E.scrobiculatus and E.brandti,with mortality rates of 55.00±1 1.55％and 57.50±19.53％,respectively,the hat type barrier had the best control effect on the adults of E.brandti with the mortality rate of 67.50±21.16％.Clarifying the niche characteristics of the two weevils under different physical barrier devices is not only of great significance for exploring the interspecific competition between the two weevils,but also provides important scientific basis for formulating comprehensive prevention and control measures for two weevils.关键词
