| 中文摘要: |
| 蝇蛹金小蜂是铃木氏果蝇和黑腹果蝇的重要天敌，本研究以黑腹果蝇为寄主，测定了蝇蛹金小蜂云南种群的生长发育、繁殖及寿命。并在6个寄主密度梯度条件下研究了其寄生功能反应。结果显示蝇蛹金小蜂从卵到雌、雄成蜂的平均发育历期分别为16.10 d和14.67 d，雌蜂平均寿命为49.76 d，平均产子代数为93.28头/雌，子代雌性比为55.76%。在黑腹果蝇蛹为5、10、15、20、25和30头的密度梯度下，蝇蛹金小蜂的寄生功能反应符合Holling II模型，其方程为Na=0.6261 No/(1+0.0632 No)。理论最高寄生量为Na max=9.0171，实际最高寄生量为7.00头（寄主密度为20头），蝇蛹金小蜂的寄生搜寻效应随寄主密度的增加而降低。综上结果，采自杨梅的蝇蛹金小蜂以黑腹果蝇作为寄主时具有较高繁殖力，较强的寄主适合度，是铃木氏果蝇和黑腹果蝇有效的生物防治作用因子。 |
| 英文摘要: |
| Pachycrepoideus vindemmiae is a nature enemy against Drosophila suzukii and Drosophila melanogaster.We tested the development, fecundity and life time of Yunnan strain P.vindemmiae on D.melanogaster. In addition, the functional response of P.vindemmiaewas tested on six different host densities (5,10,15,20,25 and 30 pupa of D.melanogaster). The development period from egg to adult of female and male were 16.10 d and 14.67 d, respectively.The average longevity of female adult was 4976 d, the average number of progeny was 93.28 per female, and the proportion of female progeny was 55.76%. The parasitic functional response of P.vindemmiaewas fitted to Holling II type.The curve was described as Na=0.6261 No/ (1+0.0632 No). The maximum number of theoretical parasitism was N amax=9.0171, the maximum number of actual parasitism was 7.00 (20 pupa were provided). The searching efficiency ofP.vindemmiae decreased with the increased host density.We conclude that P.vindemmiaecollected from bayberry has higher fecundity and fitness on D.melanogaster,so it is potential efficient biological control agent against D.suzukii and D.melanogaster. |
