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。

The transgenic regenerative rice plants were gotten. Indoor feeding corn borer by these transgenic rice regenaration plants and their descendance's tiller stem;The corn borer mortality and the worm length were compared to determinate transgenic regenerative rice's pest resistance.

我们用这些转基因水稻再生植株及其后代的分蘖茎段对玉米螟进行室内喂养，通过比较虫体死亡率及虫体生长长度，测定转基因水稻再生植株的抗虫性。1997～1999年共进行3个世代5次的室内测定。

The objective of this paper was to study from three aspects, respectively: Breeding of transgenic rice restorer line for multiple resistance against bacterial blight, striped stem borer and herbicide; Marker-assisted breeding of pyramiding rice fragrance gene and multiple bacterial blight resistance genes; Molecular mapping of transgene cry1Ab in transgenic rice.

本论文主要开展了三个方面的研究：多抗性(抗白叶枯、螟虫、除草剂)转基因水稻恢复系的培育；水稻香味基因与抗白叶枯基因的聚合育种；转基因水稻中转cry1Ab基因的分子标记定位。

Through marker-assisted selection in self-cross populations we obtained transgenic restorer line T773 carrying three genes (cry1Ab, bar and Xa21) with resistance to bacterial blight, striped stem borer and herbicide.

2利用Tail-PCR技术获得转基因水稻中外源cry1Ab基因插入的侧翼序列，通过序列比较分析确定了转cry1Ab基因在水稻基因组插入的物理位置。

Breeding of transgenic rice restorer line for multiple resistance against bacterial blight, striped stem borer and herbicide(1) Transgenic rice line Zhongguo91 (carrying cry1Ab and bar gene) and elite restorer line Hui773 were crossed, then backcross was carried out three times using Hui773 as recurrent parent and self-cross was carried out one time.

多抗性(抗白叶枯、螟虫、除草剂)转基因水稻恢复系的培育(1)将恢773与携有转cry1Ab和bar基因的水稻新品系中国91(cry1Ab)杂交，并以恢773作为轮回亲本，连续回交三代和自交一代，对各回交世代的单株进行cry1Ab和bar基因的PCR分析、田间抗虫性鉴定和除草剂Basta抗性鉴定，经过选择获得了转基因水稻恢复系T773-1，田间种植对螟虫及除草剂Basta表现很好的抗性。

If sprayed too late, the corn borer will already have made a home inside the corn stem and will not be killed.

如果杀虫剂喷洒得太晚，玉米螟早已经在玉米茎的内部安家了。这样，它们就不能被杀死。

If sprayed too late, the corn borer will already have made a home inside the corn stem and will not be killed.

如果喷的太迟，玉米螟已经在茎里做窝，无法把它们杀死。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
