| 摘 要： | 灰钝额斑螟Bazaria turensis Ragonot是柴达木盆地白刺(Nitraria sp.)灌丛的主要害虫,为了有效控制该害虫对白刺的危害,采用室内饲养和田间定点观察,对灰钝额斑螟进行了生物学特性观察。结果表明灰钝额斑螟在柴达木盆地1年发生1代,有卵、幼虫、蛹和成虫4种虫态,通过头壳宽确定了幼虫为5个虫龄,以滞育蛹越冬。翌年5月中旬开始羽化,5月下旬为羽化高峰期,6月中旬孵化,6月下旬为孵化盛期,8月上旬开始结茧化蛹,8月中旬结茧化蛹高峰期,随后蛹进入滞育越冬。6月下旬初龄幼虫发生盛期是该害虫防治的最佳时期。 |

| Abstract: | Bazaria turensis Ragonot is an important pest of the shrub Nitraria sp.in the Tsaidam Basin.In order to control its damage to Nitraria roborowskii Kom.,the biology of B.turensis was investigated in the field and in laboratory experiments.The results show that this moth has complete metamorphosis and is univoltine in the Tsaidam Basin.The larvae always passed through five instars after which they pupate and overwinter in soil.Adults emerged the following mid-May with a peak of emergence in late-May.Eggs hatc... |
