The nun moth, Lymantria monacha L., is one of the most important defoliators of Eurasian coniferous forests. Outbreaks during 2011–2015 in the natural/planted larch, and larch‐birch mixed forests of the Greater Khingan Range in Inner Mongolia, China, caused tremendous timber losses from severe defoliation and tree mortality. A series of trapping experiments were conducted in these outbreak areas to...
Development of theory and technology of wireless sensor network (WSN) has made it possible to satisfy the new demand for location-based services such as location based access control. However, most of existing techniques do not take into account the security of location estimate of some access node whose goal would be to try to confuse the localization system by amplifiers and high gain antennas....
The grey‐spotted tussock moth, Orgyia ericae Germar (Lepidoptera: Lymantriidae), is an important pest of deciduous trees and woody scrublands in northern China. In a field trapping experiment conducted during the flight of the first generation of 2009, synthetic (Z)‐6‐heneicosen‐11‐one, a common Orgyia spp. sex pheromone component, attracted O. ericae males. Gas chromatography‐mass spectrometry analyses...
Combine the actual situation of stope collapse area 56-7# of Dongguashan Copper Mine in china, three-dimensional dynamic monitoring the collapse area twice using Cavity Monitoring System (CMS), taking collapse area measured data as foundation, collapse area three-dimensional model created using Surpac and gain three-dimensional configuration and the actual boundary of the collapse area accurately...
