AbstractTo understand the composition of insect species in the sanzhan forest farm of Shengshan Nature Reserve in Heilongjiang Province,a background survey of insects was conducted in the area,thespecies composition and dominantspecieswereanalyzed,andasimilarityanalysis ofinsectcommunitiesacross diferenthabitats was performed. The resultsshowed thata totalof1873 insectsamples werecollected,belongingto11orders,86familiesand173 species.Among them,Lepidoptera had thelargest number,with 22 families,69 species and702 individuals,acounting for 25.58% of all families and 39.88% of all species.In the order Coleoptera, there were 19 families,3O species and 566 individuals,with the proportions of the number of families and species being 22.09% and 17.34% respectively. Lepidopteraand Coleoptera were thedominant insect ordersinthestudyarea.Holotrichiaparalela,Opatrum subaratum,Furculafurcula,Pieris rapae,Inachis ioandothers were thedominant insectspecies.The similarityindices ofeach habitat from high to low were meadow-marsh (0.461)> marsh-farmland (0.412)> tree-meadow (0.355)> meadow-farmland (0.339)> tree-marsh (0.313)> tree-farmland (0.274),among which the similarity index of meadowmarshhabitatisrelativelyhighThisarticleprovidesareferencefortheprotectionofbeneficialinsects,pestcontrol,and the rational development and utilization of insect resources in relevant regions.
