摘要: 用卷叶率、为害级别和严重度3个指标评价了克螟稻2号及其亲本秀水11对稻蓟马的抗感性。结果表明,克螟稻2号较秀水11在3种指标上存在着极显著的差异,克螟稻2号较感虫;两品种上单位叶面积成虫数量差异均不显著,而卵量和若虫数量的差异显著;说明高密度的稻蓟马若虫将对克螟稻2号为害更严重。

Abstract:

Three indices, i.e. severity, percentage of rolled leave and injure degree were used to evaluate the virulence of Thrips oryzeato both Bt gene transformed rice Kemingdao 2 and it's original parent Xiushui 11. The results indicated that Kemingdao 2 is much more susceptible to the rice thrips than Xiushui 11. There were no significant difference at thrips’ adult populations, while significant difference at eggs and nymphs population between Kemingdao 2 and Xiushui 11.It is indicated that a higher nymph population could cause more serious injure in Kemingdao 2.
