In 2014 autumn and 2015 spring,using rubidium-marking and fluorescence powder-marking techniques,the migration distances of Apolygus lucorum in spring and autumn and its seasonal host transfer rules were studied in an experimental orchard of Ziziphus jujube Mill.,which belonged to Puyang City Academy of Forestry. The results indicated that,in Henan jujube area,A. lucorum mainly fed on the jujube trees,which were the main host plants of this pest in spring. Under the condition of stable environment and ample food sources,the migration rate of A. lucorum was slow. The longest migration distance was 400 m within two weeks in the experimental jujube orchard. In autumn,A. lucorum transferred to other host plants from jujube trees. It had strong ability of migration,and the longest migration distance was 4 km within two weeks during autumn,reaching the longest distance observed in the experimental orchard. That was,this pest would like to take a long journey through the orchard in search of their preference host plants in order to stay alive. Humulus scandens,Artemisia argyi,Cucurbita moschata,Xanthium sibiricum,Vigna radiata,Vigna unguiculata,etc. were their main autumn hosts.
