以长春地区的水曲柳林分为对象，调查白蜡吉丁的自然天敌种类及优势天敌，结果表明：白蜡吉丁卵期优势天敌种类为白蜡吉丁平腹小蜂，寄生率达61．3％；幼虫期优势天敌种类为白蜡吉丁啮小蜂，寄生率为68．6％；蛹期寄生天敌种类一种，为东方副凿姬蜂，寄生率为8．64％。白蜡吉丁产卵的季节分布呈先上升至高峰后再下降的趋势，白蜡吉丁平腹小蜂的季节消长趋势与白蜡吉丁一致，但在时间上滞后于白蜡吉丁产卵的规律。白蜡吉丁平腹小蜂可以作为一种潜在的、可开发的优势天地种类对白蜡吉丁进行生物防治。

Fraxinus mandshurica was taken as object to survey natural enemy species and dom-inant natural enemy of Agrilus planipennis Fairmaire, the results indicated that the dominant natural enemy species was Oobius.agriliin in egg stage, and the parasitic rate was 61.3%;in larval phase, the dominant natural enemy species was Tetrastichus planipennisi Yang, the para-sitic rate was 68.6%; in pupal period, parasite natural enemy was Deuteroxoridea orientalis Uchida, the parasitic rate was 8.64%.Seasonal distribution trend of oviposition was rising to the peak and then downward , seasonal growth and decline trend of Oobius.agrili was the same to Agrilus planipennis Fairmaire , and it lagged behind spawning rule of Agrilus planipennis Fairmaire on the time.Oobius.agrili could be used as a potential and developed species for bi-ological control against Agrilus planipennis Fairmaire.
