[Objective]The paper was to investigate the occurrence of Lithocolletis ringoniella adults in aged and new apple orchards in Shijiazhuang area.[Method]The growth and decline dynamics of L.ringoniella adults in 3a apple orchard and 17a apple orchard in Shijiazhuang were monitored by sex attractant trapping method.Meantime,the trapping effects of sex attractant on L.ringoniella were compared with that of sweet-sour liquor.[Result]L.ringoniella occurred five generations annually in Shijiazhuang area.The adults emerged in April,and entered into peak occurrence period during May and June,with overlapping generations.Comparison between sex attractant and sweet-sour liquor tests showed that the trapping effect of sweet-sour liquor received little effect,but was expensive.Therefore,it is not recommended to use sweet-sour liquor for prevention and treatment of L.ringoniella in production.[Conclusion]In the actual production,sex attractant trapping should be combined with appropriate agricultural control measures to control the damage of L.ringoniella. 展开更多
