【摘要】 凹唇壁蜂雌蜂卵巢由六根卵巢管组成,卵母细胞总数平均为55.9±4.46个,卵原区在成虫产卵期不再产生卵母细胞。巢管的内径对种群性比存在较大影响。雌蜂实际产卵量受花期长短影响很大,雌蜂最大产卵量平均为29.8粒。果园释放后,营巢雌蜂数平均为37.15%±16%;种群最大增长率在苹果园为4.38n-1,梨园为3.96n-1,苹果、梨、桃混栽园为5.99n-1。更多还原

【Abstract】 The ovary of the female consists of six ovarioles. In free diapausing adults, the total number of oocytes in an ovary is very stable, the average oocyte number in an ovary is 55.9 ±4.46. The best record of the maximum number of eggs obtained through our experiments was 29.8.the average rate of nesting females is 37.15% ±16% in total released females.The maximal rate of population increasing was 4.38n-1 in the apple orchard, was 3.96n-1 in the pear orchard, was 5.99n-1 in the apple, pear and peach orchard.更多还原
