| 摘 要： | １９９０年以来，在黑龙江省林甸县对柳准球蚧采取了野外定期观察，室内饲养观察及人工接种。结果表明：１年发生一代；以２龄若虫在柳树的枝干部越冬，成虫的发生期为５～６月中旬，６月中旬出现初孵若虫。柳准球蚧有三种寄生蜂，其中跳小蜂的控制力最强，一年发生两代，越冬代寄生率为１２．１％，第一代寄生率为６５％。

| Abstract: | Scince 1990,ragular indoor,field observation and artificial propagation was used for studying on the Eulecanium Circumfluum Borchs in Lindian county Heilongjiang Province.The results show that.the pest happens one generation every year,overwinters on branches by 2nd instar nymph,the adult mature period is between middle of May and middle of June;lst instar nymph emerges in middle of June.On the scale insect,there are three species of parasite chalcids, one of the encyritid has the best control capacity on the pest,occurring two generations a year.The parasite rate of overwintering generation is 12.1,while that of lst generation is 65%. |
