Abstract
For the sake of finding out the law s of insect pest damage to apricot trees and providing the basis for contro lling the pes,t samp le plotmethod w as applied to investigate the apricot tree stand. The diversity and insect commun ity in d ifferent intercropping andmanag ing apricot tree stand yard ecosystems in Y ingjishaw ere studied. The resu lts show ed that therew ere 37 species of insects belong ing to 9 orders and 26 fam ilies in d ifferent aprico t tree standyard ecosystems in Y ing jisha. The number o f orders and species and individualw ere not the same in different apricottree stand yard ecosystem s. In different ecosystem s, the proportion of principa l insect community groups w as differen,t so that the diversity and evenness and dom inant concentration index w ere no t the same. Annual dom inant species in each aprico t tree stand yard w as mainlyD idesmococcus koreanus. The dom inant concentrat ion index o f insectcommunity and its principa l groups w as not the sam e in d ifferent tim e and apricot tree stand yards.
