Study On The Structure And Diversity Of Garden Insects In Alar City

This paper investigates the insect community and the species diversity of the main habitat types in alar urban landscaping poplar forest,haitang nursery,roadside trees and paraffin hedgerows.The results were as follows:1.The total collection of insects in the four habitats of alar gardens including poplar patch forest,haitang nursery ground,luan tree line tree and paraffin green hedge were respectively 1965,4424,1319 and 1637.Among them,there are75 species in 37 families of 9 orders,98 species in 41 families of 7 orders of poplar tablets,40 species in 19 families of 4 orders of wax-green hedges,and 38 species in 17 families of 5 orders of road trees.The dominant groups are Diptera,Coleoptera,Hemiptera,hyperitera.2.In different habitat insects function groups of different distribution of garden greenbelt,the number of plant hoppers in iminqak accounts for more than 31.03% of the total number of individual insects,plant hoppers species accounted for 28.42%,Chinese flowering crabapple seedling plant hoppers to 46.56%,the number of predatory insects accounted 26.84%,trees and water wax hedge plant hoppers accounted for 34.24% and 25.28%,predatory insects accounted for 25.9% and 16.59%,in iminqak trees suffer the risk is low.3.In the year with the passage of time,the city 5,6,7,8,9 months,as temperatures rise,the number of insect growth to a certain extent,because of the temperature decrease during October,insect populations showed a trend of decline,the insect diversity found in the analysis,the Chinese flowering crabapple seedling in insect populations,the most abundant in July due to the influence of the chemical control of insect populations and population decline significantly,in iminqak richness index in different months,diversity index and the change trend are relatively stable and insect community special,with stable and water wax insects of trees along the hedge and low abundance,At the same time,the most affected by chemical control,the insect diversity index of the four habitats was from high to low: > populus euphratica forest > water-wax hedge > roadside trees in haitang nursery.In different habitats,the community structure and diversity of insects have significant changes,which means that the living environment of insects has a significant impact on insects,and it also indicates that insects have the function of ecological indicator probe.4.Through to the aral sea landscape diversity of insect communities in different habitats and different research,found that different types of plant and environment and the chemical control of manual intervention for insects,which human intervention because the smaller piece of Lin has good ecological stability,because the Chinese flowering crabapple nursery compared relatively rich plant species of insect communities,and is located in the urban water wax hedge and doers of the word because of the single plant species,human intervention chemical control is more,insect species richness is lower,and a single insect diversity.
