Community structure and seasonal dynamics of arthropod in Guangxi mulberry field
摘要
Abstract
[Objective]Community structure and seasonal dynamics of arthropod in Guangxi mulberry field were studied to provide scientific references for integrated control of mulberry pests and the rational use of natural enemies.[Method]The number of individuals and species of arthropod in mulberry field were surveyed,and then the community structure and seasonal dynamics were analyzed with species richness index,Shannon diversity index,Simpson diversity index,Brillouin diversity index,Pielou evenness index and Simpson dominance index,when the community similarity in four seasons were analyzed with similarity index.[Result]Of all 17371 arthropods,totally 26 arthropod species were obtained from mulberry field,which belonged to 13 orders and 26 families.There were 18 herbivorous pest species,where the dominant species were Tetranychus cinnabarinus Boisduval and Bemisia myricae Kuwana.There were 5 natural insect enemies,where the dominant species was micraspis discolor Fabricius.There were 2 spider species,almost all of which were Tarantula sp.There was 1 neutral insect species.The diversity index sequence of communities in the mulberry field was as follows:winter ＜ autumn ＜ summer ＜ spring.Pielou evenness index and diversity index had the same trend,while Simpson dominance index was low all the year round,and reached its lowest point in spring.Community comparability coefficient was in a very dissimilar level between spring and other seasons (Rj=0.2329,0.0000,0.2077).It was in a moderate similar level between summer and autumn (Rj=0.5461).It was in a moderate dissimilar level between summer and winter (Rj=0.3322),and it was in a very dissimilar level between autumn and winter (Rj=0.1297).[Conclusion]Species diversity index and evenness index were both high,when the dominant concentration index was low,so the community structure was stable and reasonable in Guangxi mulberry field.关键词
