应用作用因子生命表方法以及在此基础上提出的排除作用控制指数法评价了寄生蜂对美洲斑潜蝇自然种群的控制作用.结果表明,底比斯釉姬小蜂、丽潜蝇姬小蜂、冈崎釉姬小蜂、异角姬小蜂、黄潜蝇姬小蜂、甘蓝潜蝇茧蜂和离潜蝇茧蜂对美洲斑潜蝇种群有重要的控制作用,春季菜豆上美洲斑潜蝇连续5个世代中,若排除寄生蜂作用,美洲斑潜蝇的种群数量将比原种群增长1.23、2.73、5.98、5.92和5.71倍;在春季菜豆、豇豆、丝瓜和黄瓜上第2代美洲斑潜蝇中,若排除寄生蜂作用因子后,美洲斑潜蝇在上述4种蔬菜上的种群数量将分别多增长2.73、2.87、2.24和1.89倍.寄生蜂对美洲斑潜蝇3龄幼虫的控制作用大于1龄、2龄幼虫和蛹的控制作用;春季美洲斑潜连续世代中,第1、2代寄生蜂的控制作用较第3、4、5代低;寄生蜂在菜豆和豇豆上的控制作用比在丝瓜和黄瓜上高.
應用作用因子生命錶方法以及在此基礎上提齣的排除作用控製指數法評價瞭寄生蜂對美洲斑潛蠅自然種群的控製作用.結果錶明,底比斯釉姬小蜂、麗潛蠅姬小蜂、岡崎釉姬小蜂、異角姬小蜂、黃潛蠅姬小蜂、甘藍潛蠅繭蜂和離潛蠅繭蜂對美洲斑潛蠅種群有重要的控製作用,春季菜豆上美洲斑潛蠅連續5箇世代中,若排除寄生蜂作用,美洲斑潛蠅的種群數量將比原種群增長1.23、2.73、5.98、5.92和5.71倍;在春季菜豆、豇豆、絲瓜和黃瓜上第2代美洲斑潛蠅中,若排除寄生蜂作用因子後,美洲斑潛蠅在上述4種蔬菜上的種群數量將分彆多增長2.73、2.87、2.24和1.89倍.寄生蜂對美洲斑潛蠅3齡幼蟲的控製作用大于1齡、2齡幼蟲和蛹的控製作用;春季美洲斑潛連續世代中,第1、2代寄生蜂的控製作用較第3、4、5代低;寄生蜂在菜豆和豇豆上的控製作用比在絲瓜和黃瓜上高.

The controlling effect of parasitoids on vegetable leaf miner, Liriomyza sativae Blanchard, was evaluated by using act
ing factor life tables and exclusion inex of population control(EPIC). The results showed that Chrysocharis pentheus,
Neuchrysocharis formosa, Chrysonotomyia okazakii, Hemniptarsenus varicornis, Chrysocharis sp., Opius dimidiatus and Opius dissitus played an important role in controlling the population of vegetable leaf miner. The EIPCs of parasitoids were 1.23, 2.73, 5.98, 5.92 and 5.71, respectively for the five generations of L. sativae on kidney bean planted in spring, from the 1st to the 5th generation and, for the 2nd generation in particular, they were 2.73, 2.87, 2.24and 1.89, respectively on kidney bean, cowpea, luffa and cucumber, indicating that if the parasitoids were excluded, the population of the next generation of L. sativae would increase by times accordingly. The EIPC of parasitoids for the 3rd instar larvae was usually the largest among different instar larvae and pupae, and the EIPCs for the 3rd to 5th generation of L. sativae on spring kidney bean were higher than those for the 1st and the 2nd. The EIPCs of parasitoids for L. sativae on kidney bean and cowpes were larger than those on luffa and cucumber.
