茶细蛾雕绒茧蜂 Glyptapanteles theivorae Shenefelt 和羽角姬小蜂 Sympiesis soriceicornis Nees 是自然控制金纹细蛾 Lithocolletis ringoniella Matsumura 的优势寄生蜂.在室温条件下采用单头饲养的方法测定了外源营养浓度和饲喂次数对两种寄生蜂寿命的影响及日取食规律.结果表明,补充不同浓度外源营养均能够延长两种寄生蜂的寿命,用300 g·L?1外源营养饲喂,两种寄生蜂寿命最长,其余浓度对寿命的影响,以300 g·L?1>200 g·L?1>400 g·L?1>100 g·L?1>500 g·L?1为序变短;饲喂次数大于1次/2 d 可显著延长两种寄生蜂寿命,且饲喂次数增加,寿命延长;持续供食时,茶细蛾雕绒茧蜂平均寿命延长3.8~4.2倍,羽角姬小蜂成蜂延长3.9~4.2倍;两种寄生蜂的日取食节律分别在9:00-10:00和12:00-17:00出现两个高峰,且种间、种内性别间均有明显的错峰现象.

@@@@Glyptapanteles theivorae and Sympiesis soriceicornis are dominant parasitoids of Lithocolletis ringoniella. Influence of concentration of nutrient solutions and feeding times on the life span of these two wasps was measured against individual wasp at controlled room temperature. The lifespan of these two wasps can be extended through supplementing different concentrations of nutrient solutions, the influence was ranked as: 300 g·L?1 >200 g·L?1>400 g·L?1>100 g·L?1 >500 g·L?1. The lifespan was also significantly extended with the feeding times. The lifespan of G. theivorae was extended by 3.8—4.2 times and that of S. soriceicornis was by 3.9—4.2 times under continual feeding regime. The feeding rhythms of the two wasps was characterized by two peaks at 09:00—10:00 am and 12:00—17:00 pm, but were obviously different between species and sex.
