摘　　要：以盛花期至落花期不同花色的日本晚樱为调查对象,研究其访花昆虫的物种组成及访花行为。经调查,共捕获749头昆虫,属7目41科。优势群落以鞘翅目与半翅目昆虫为主,个体数量分别为303头和186头,各占捕获昆虫数量的40.45%和24.83%,访花行为以取食花朵为主。在不同花色间日本晚樱的访花昆虫群落多样性、访花行为差异大。不同颜色日本晚樱多样性指数从高到低顺序为淡粉色>绿色>淡绿色>粉色;均匀度指数大小排序为淡粉色>绿色>淡绿色>粉色;优势度指数大小排序为粉色>淡粉色>淡绿色>绿色;丰富度指数大小排序为淡粉色>绿色>粉色>淡绿色。淡粉色品种的多样性指数、均匀度指数、丰富度指数均高于其他品种,而优势度较低,可见该品种的访花昆虫种类丰富且群落稳定。This study takes Prunus lannesiana of different colors from peak flowering to fading period as study ob-ject,followed by a study on the composition of follower-visiting insects and their visiting behaviors.A total of 749 insects belonging to 7 orders and 41 families were captured.The dominant community was Coleoptera and Hemip-tera,with 303 and 186 individuals,accounting for 40.45%and 24.83%of the captured insects,respectively.The flow-er visiting behavior was mainly for flower feeding.The commnity and behavior diversity of visiting insects vary greatly from different flower colors of Prunus lannesiana.The diversity index of Prunus lannesiana of different col-ors from high to low was light pink>green>light green>pink.The order of evenness index was light pink>green>light green>pink.The order of dominance index was pink>light pink>light green>green;and the or-der of richness index was light pink>green>pink>light green.The diversity,evenness and richness index of the light pink cultivar were higher than those of other cultivars,while the dominance was lower,indicating that the spe-cies of flower-visiting insects of this cultivar were abundant and the community was stable.
