Resource use overlap between Epiblema strenuana and Ostrinia orientalis: two biocontrol agents against Ambrosia artemisiifolia and Xanthium sibiricum
豚草卷蛾与苍耳螟的资源生态位研究

The imported ragweed borer Epiblema strenuana (Lepidoptera: Tortricidae) and local Siberian cocklebur stem borer Ostrinia orientalis (Lepidoptera: Pyralidae) are important biocontrol agents against ragweed ( Ambrosia artemisiifolia ) and have similar feeding characteristics In order to evaluate interspecific interactions between these two biocontrol agents, food and spatial overlap were evaluated quantitatively in 2001 in the Field Experimental Station of Hunan Agricultural University, Changsa C...
