白生盘蚧Crescoccus candidus Wang研究初报

A PRELIMINARY STUDY ON CRESCOCCUS CANDIDUS(HOMOPTERA:LECANODIASPIDIDAE)

    摘要
  • 摘要: 生盘蚧属Crescoccus白生盘蚧Crescoccus candidus系王子清1977年采自云南大理,并于1982年建立生盘蚧属(新属),白生盘蚧(新种)。其副模系作者于1979年采自云南丽江。1983年至1986年以昆明温泉羊角村为基点,对其生物学习性及综合治理进行研究。该虫主要为害板栗Castanea mollissima、青冈Cyclobalanpsis glauca、麻栎Quercus acutissima,亦可为害苹果;是板栗树的主要害虫。在昆明地区一年一代,以雌成虫在被害枝条上越冬。雌虫产卵高峰期为6月中旬,初孵若虫涌散峰期为6月中旬,1龄若虫峰期为7月中旬,2龄若虫峰期为9月中下旬,雄虫羽化峰期为10月中旬,6月中旬,10月中旬是化学药剂防治初孵若虫及雄虫的有利时机。生命表资料表明各种自然因子致死率达97.8%,因此加强抚育管理,保护利用天敌,适期使用化学农药是治理白生盘蚧的主要措施。雨水冲刷,二种跳小蜂,长尾小蜂,瓢虫等是控制白生盘蚧种群数量的关键因子;每10cm2有虫19头可定为防治阈值。

     

    Abstract: Crescoccus candidus Wang infeststrees belonging to Fagaceae such as Castanea mollissima and Cyclobalanopsis glauca etc, It Causes great damage to Castanea mollissima, This pest has one generation a year in Kunming, The female adults over-winter on the infested twigs, The peak of spreading period of the newly hatching nymphs is in the middle of June; emergence of the male adults at its height is in the middle of October. These two dates are effective for the chemical control. The life table of this scale insect shows that the population mortality percentage reaches 97.8%. Two species of the Encyrtid parasites are the natural controlling agents of the pest population density. The economic Threshold for chemical control has been determined as 19/10cm2.
