Transgenic corn (MON 810), expressing the Bacillus thuringiensis (Bt) protein, Cry1Ab, was evaluated under greenhouse conditions for its tolerance to the maize stem borer, Chilo partellus. Bt corn (MON 810) provided effective protection against the stem borer even under a high level of larval infestation in the greenhouse. The observed tolerance is examined and discussed in the light of the susceptibility of C. partellus to the Cry1Ab protein in laboratory bioassays. The implications of the tissue concentrations of Cry1Ab in MON 810, and baseline susceptibility recorded in the current study, for insect-resistance management are discussed.
对表达苏云金芽孢杆菌(Bt)Cry1Ab蛋白的转基因玉米(MON 810)在温室条件下对玉米螟(Chilo partellus)的耐受性进行了评估。即使在温室中幼虫侵染水平较高的情况下,Bt玉米(MON 810)也能为抵御玉米螟提供有效保护。根据实验室生物测定中玉米螟对Cry1Ab蛋白的敏感性,对观察到的耐受性进行了研究和讨论。还讨论了MON 810中Cry1Ab的组织浓度以及本研究记录的基线敏感性对昆虫抗性管理的影响。
