查询词典 accretion borer

Rice stem borer resistive to Bt is not selected out by rearing with high concentration Bt protein in short time and low concentration Bt protein in long time.

采用高浓度Bt制剂短时饲喂和低浓度Bt制剂整代饲喂两种途径对二化螟抗Bt品系进行了初步的选育，饲养的三代二化螟均没有对Bt制剂产生抗性。

Through selection we obtained transgenic restorer line T773-1 with good agronomic traits and obvious resistance to striped stem borer and herbicide.

3转cry1Ab和bar基因的水稻恢复系T773-1和转Xa21基因的恢复系T773-2进行杂交、自交，对自交世代单株进行cry1Ab、bar和Xa21基因的分子标记辅助选择，获得了带有三基因的恢复系T773，田间种植对水稻白叶枯病、鳞翅目害虫、除草剂具有很好的抗性。

The foreign PinⅡ gene could increase stem borer resistance of DH lines and enlarge the possibility of screening for resistance lines.

应用F〓群体cw3和DH群体对第6染色体waxy基因附近的5个SSRs标记作图，分别得到覆盖51.7cM和57.9cM的连锁群。

Strain＇E-916 not only kept the antagonistic action on rice sheathblight disease, but acquired the insecticidal activity to rice stem borer through genetic engineering.

杀虫和抑菌试验结果表明构建的工程菌对水稻二化螟具有杀虫活性，且保持了其原有对水稻纹枯病的拮抗性能。

Sugarcane stem borer and Ceratovacuna lanigera Zehnther are the main pests of sugarcane, which not only make sugarcane yields loss but also make sucrose content decline.

蔗螟和绵蚜是甘蔗的重要害虫，它们不但造成甘蔗产量损失、蔗糖含量的下降，还传播多种甘蔗病毒，传病造成的损失比直接为害造成的损失更为严重。

Effect of transgenic sck+cry1Ac rice on mortality and fresh weight of the stripped stem borer Chilo suppressalis, and biological characteristics of Apanteles chilonis via its host SSB was studied in the laboratory.

在实验室研究了转sck+cry1Ac基因水稻对二化螟Chilo suppressalis生长、存活以及经寄主对二化螟绒茧蜂Apanteles chilonis生物学特性的影响。

The age structure of striped stem borer, Chilo suppressalis, overwintering in different type of rice fields and wild rice fields was investigated, and post winter feeding and pupation dynamics were compared among larvae in different instars.

调查了不同类型稻田及茭白田中二化螟的越冬年龄结构，比较了不同龄期幼虫之间在冬后取食与化蛹动态方面的差异。结果表明，越冬虫龄以双季晚稻田中明显较低，中稻田与茭白田中相对较高。

By field breeding, we finally acquired 3 transgenic lines with good agronomic traits: SK-1, SK-2, and SK-3, which all showed obvious resistance to stripe stem borer and Xanthomonas oryzae pv. oryzae. The yield potentials were about 20% higher than those of Zhendao88 and Shengdao301; the quality was similar and some features were better.

通过田间选育，获得了农艺性状优良的双抗转基因水稻新品系SK-1、SK-2、SK-3，3个品系均对二化螟和白叶枯病菌表现出显著的抗性，产量高于镇稻88和圣稻301近20%，品质与镇稻88和圣稻301相近，部分指标优于这两个品种。

A carrier gas such as nitrogen is directed through line 20 and valve 22 to connect with line 26 and mix with the gas sample.

如氮气之类的载体通过管线20和阀22引入，与管线26相通，与气体样品混合。

But for the most part, knaves and parasites had the command of his fortune

然而支配他的家产的大多是恶棍和寄生虫。
