摘要
日本细毛环腹瘿蜂为斑翅果蝇幼虫优势寄生性天敌之一,对斑翅果蝇具有较大的控制潜能。本研究以斑翅果蝇为寄主,在实验室条件下,通过饲养与观察,研究了日本细毛环腹瘿蜂的寿命、行为节律、寄主选择、生长发育及繁殖。结果显示:不同营养条件下,寄生蜂寿命长短依次为20%蜂蜜水>10%蜂蜜水>清水>对照。寄生蜂羽化期为8 d,第4天为羽化高峰期,羽化期每日10∶00-12∶00为羽化高峰期,16∶00-18∶00为产卵活动高峰期。寄生不同龄期的斑翅果蝇幼虫对寄生蜂幼虫存活率没有影响,对蛹存活率、后代性比、总发育历期有显著影响,寄生2龄幼虫对寄生蜂有更好的适合度,也对寄主2龄幼虫有选择偏好。日本细毛环腹瘿蜂在3日龄达到产卵高峰为13.38头,平均每雌产卵147.50个。日本细毛环腹瘿蜂卵、幼虫、雄蜂蛹、雌蜂蛹历期分别为1.30 d、8.67 d、8.86 d、10.27 d,雄蜂的羽化时间比雌蜂平均提前1.41 d。综上结果,日本细毛环腹瘿蜂可作为斑翅果蝇生物防治的重要材料加以应用。
Leptopilina japonica is one of the dominant parasitic natural enemies of Drosophila suzukii larvae,and has great potential for controlling D.suzukii.In this study,D.suzukii was used as the host.Through breeding and observation,the longevity,behavior rhythm,host selection,growth and development,and reproduction of L.japonica were studied under laboratory conditions.The results showed that,the life span of parasitoid varied under different nutritional conditions:20%honey water>10%honey water>clear water>control.L.japonica emergence period was 8 days and on the 4 th and the daily from 10∶00-12∶00 was peak of emergence;the peak of oviposition activity occurred at 16∶00-18∶00.Parasitic D.suzukii larvae at different developmental stage had no effect on the survival rate of parasitoid larvae,but significantly influenced the survival rate of pupae,the progeny sex ratio,and the total developmental duration.Parasitizing 2 nd instar larvae had better fitness and also prefer to 2 nd instar larvae of D.suzukii.At the age of 3 days,the peak oviposition of L.japonica was reached to 13.38 individual,with an average of 147.50 eggs per female.The egg,larval,male pupal and female pupal duration of L.japonica was 1.30 d,8.67 d,8.86 d and 10.27 d,respectively.The emergence time of the male was 1.41 d earlier than that of female.The results suggested that the L.japonica could be used as a potential and effective biological control material in D.suzukii control.
