| 摘 要： | 副珠蜡蚧阔柄跳小蜂Metaphycus parasaissetiae Zhang and Huang是新发现的橡副珠蜡蚧成虫内寄生蜂,自然寄生率约为15.68%。实验室内对其形态、发育、繁殖、存活、行为等生物学特性进行了观察。结果表明,在26±1℃,RH70%±5%条件下,每头寄主出蜂4.5头,雌性比例80.6%;雌蜂生殖系统解剖发现,未交配雌蜂卵巢内的卵经1d可发育成熟,但同一雌蜂卵巢内卵粒之间发育程度不一致;该蜂完成一个世代需15～19d,但幼虫蜕皮现象不明显;该蜂可营孤雌产雄生殖,孤雌羽化后24h内即可产卵,平均每头寄主可出雄蜂5.3头;雌蜂交配后24h内即可产卵,产卵期1～17d;1头已交配雌蜂可寄生1～10头寄主,一生产卵3～76粒,每日平均产卵量为8.2±4.0粒;雌、雄成蜂平均寿命均不超过3d,补充蜂蜜水可延长雌、雄成蜂的寿命。

| Abstract: | Metaphycus parasaissetiae Zhang and Huang is a newly recorded endoparasitoid of Parasaissetia nigra （Nietner） adults. The natural parasitic rate of this wasp is about 15.68%. Its morphology, development, reproduction, survival and behavior were studied in the laboratory. At 26 ± 1 ℃ and 70 % ± 5 % RH, the average number of parasitoids emerged from each host was 4.5, among which 80.6 % were females. Eggs in the ovaries of unmated female matured after 1 d, but the development of the eggs in a female＇s ovary was not consistent. It took 15 to 19 d for the wasp to complete one generation under the laboratory condition. Larval molting was not obvious. The unmated females could only produce male progeny by parthenogenesis. Unmated females could lay eggs within 24 h after eclosion and the average amount of males emerged from each host was 5.3 under the laboratory condition. The mated female adults oviposited within 24 h and the oviposition lasted 1 - 17 d. A mated female adult laid 3 to 76 eggs during its life span, parasitizing 1 - 10 hosts. Daily oviposition rate of the parasitoid was 8.2 ± 4.0 eggs. The longevities of males and females without nutritional supplements were less than 3 d under the laboratory condition, but were prolonged with supplement of honey solution. |
