AbstractTo explore the diversity of insect communities in the Forest Botanical Garden of Heilongjiang Province， this studyconductedabackground surveyof insects inthearea during the spring and summer of2O24 through methods suchas plotinvestigation，transectinvestigation，andlight trapping.Thespecies omposition was investigated，and he causesof thedominant orderand the similarityof insect communities in diferent habitats were analyzed.A total of 2 125 insects were colected，belonging to12orders，69familiesand187species.Among them，Lepidoptera was the dominant order，with 81 species，accounting for 43.316% of the identified species，followed by Coleoptera，Diptera and Hemiptera.Thedominant species included Holotrichia diomphalia，Harmoniaaxyridis，Pyrhaltaaeneescens，Aedes communisand Hydrocharaaffnis.Therich plantresources，multi-level habitat andthe introductionof ornamental plants inthe park were the key reasonswhy Lepidoptera had become thedominant order.The insect communities in forestland-meadow were moderatelydissimilar（0.389），while those inartificial lake-meadow （O.168）and forestlandartificiallake（O.O5O）were extremelydisimilar.Inaddition，theinvestigation found thattherewere54speciesof resource insects in thearea.Itissuggested that ecological regulationbeimplemented topromote their protectionand utilization，andtodrive the sustainable developmentofeco-tourismand agricultureand forestry.This study provides a reference for the conservation and scientific management of biodiversity in botanical gardens.
