| 摘 要： | 首次对双斑恩蚜小蜂Encarsia bimaculata Heraty et Polaszek雌蜂的胚胎发育全过程进行连续观测和数码摄像,明确了双斑恩蚜小蜂的生殖方式是两性产雌,雌蜂为初寄生蜂,孤雌产雄且雄蜂为自复寄生。雌蜂在温度(25±1)℃,相对湿度70%±10%条件下,从卵到成虫的发育历期为(13.1±2.5)d,卵期(1.98±0.38)d,幼虫1龄(0.95±0.33)d,2龄(2.48±0.40)d,3龄(3.46±0.43)d,预蛹(0.95±0.20)d,蛹(4.88±0.80)d。

| Abstract: | The embryo development of Encarsia bimaculata was observed for the first time. Results showed that the fertilized eggs developed into primary parasitoid females, while unfertilized eggs developed into autoparasitoid males. The female, from egg to adult, took (13.1±2.5) d at (25±1)℃ and 70%±10% RH. The stage of egg was (1.98±0.38) d, the first instar larva was (0.95±0.33) d, the second instar was (2.48±0.40) d, the third instar was (3.46±0.43) d, and the pre-pupa and the pupa spent (0.95±0.20) d and (4.88±0.80) d, respectively. |
