中文摘要	内蒙古西部干旱地区,柠条豆象、豆荚螟、柠条种子小蜂3种柠条种子害虫成虫期均在5月中旬至6月中旬;成虫羽化高峰在6月上旬;豆荚螟卵与柠条豆象卵出现于5月下旬,卵的数量增加高峰均在6月上旬;豆荚螟幼虫出现于6月上旬,柠条豆象和柠条种子小蜂幼虫出现于6月中旬;7月上旬,3种害虫的幼虫绝大部分进入老熟阶段.豆荚螟卵和柠条豆象卵主要集中于植株上部,中、下部较少;萼筒外的柠条豆象卵量高于萼筒内,64.58%柠条豆象卵位于萼筒外,35.42%位于萼筒内;柠条豆象卵的孵化率呈逐日上升态势,7月上旬,柠条豆象卵死亡率达62.14%;由6月上旬至6月下旬,豆荚螟卵的死亡率呈逐日增加态势,但因其全部位于萼筒之下,死亡率很低,6月下旬达到13.33%.萼筒外柠条豆象卵的存活率低于萼筒内;萼筒外卵的孵化率和死亡率均高于萼筒内.
英文摘要	Population fluctuation patterns and larvae development of Caragana microphylla seed oests in arid area of west Inner Mongolia were studied. The results showed that adult stage of Kytorhinus immixtus , Etiella zinckenella and Bruchophagus neocaraganae were all from the middle ten-day of May to the middle ten-day of June. The eclosion peak were all in the first ten-day of June. Eggs of K. immixtus and E. zinckenella appeared in the last ten-day of May and their egging peaks were in the first ten-day of June. Larvas of E. zinckenella appeared in the first ten-day of June, larvaes of K. immixtus and B. neocaraganae appeared in the middle ten-day of June. Most of larvaes of 3 kinds of pests went into mature period in the first ten-day of July. Eggs of K. immixtus and E. zinckenella distributed on the top of C. intermedia. The investigation results indicated that egg amout of K. immixtus out of calyx tubes was higher than that in calyx tubes. 64. 58% of K. immixtus eggs were out of calyx tubes, 35. 42% were in calyx tubes. The hatch rate of K. immixtus eggs increased gradually. The death rate of K immixtus eggs were high to 62. 14% in the first ten-day of July. The death rate of E. zinckenella eggs increased day by day and got to 13. 33% at the last ten-day of June. The livability of K. immixtus eggs out of calyx tubes was lower than that in calyx tubes. Hatch rate of K. immixtus eggs out of calyx tubes was higher than that in calyx tubes. The death rate of K. immixtus eggs out of calyx tubes was higher than that in calyx tubes. All the eggs of E. zinckenella were under calyx tubes, so their death rate was very low.
