| 摘 要： | 实验用聚合Cry1Ab和Cry1F基因抗虫玉米335YH、696YH的人工饲料饲养亚洲玉米螟幼虫,研究人工饲料中聚合基因玉米对其存活率和平均体重的影响.结果表明:在25%用量处理下,玉米螟幼虫的存活率均低于38%,平均体重均低于45 mg,说明聚合Cry1Ab和Cry1F基因抗虫玉米种子能抑制供试亚洲玉米螟幼虫的生长和存活.335YH 25%用量和50%用量的致死性差异不大,但50%用量比25%用量抑制幼虫生长的效果更好.696YH品种对幼虫的致死性和抑制生长效果受剂量影响较大.

| Abstract: | In this experiment,the Asian corn borer larvae were fed on the polymerization of Cry1Ab and Cry1F transgenic corn 335YH,696YH artificial diet. We study the impaction on survival and average weight of the Asian corn borer larvae. The results showed that 25% of the amount of processing, the corn borer larvae survival rate was less than 38%,the average weight was less than 45 mg. This indicates polymerization of the CrylAb and CrylF transgenic corn seed can inhibit the growth and survival of the Asian corn borer larvae. 335YH, on the 25% and 50% usage,the survival of the Asian corn borer are no significant difference,but 50% compared with 25% usage, larval on the latter grows better. Dose effects 696YH on larval lethality and inhibiting the growth. |
