Ultrasonic and ultraviolet degradation of fluorescent whitening agent CBW in water

US/UV联用降解荧光增白剂CBW的研究

Abstract Presents common used CBW agents in the CBW attacks against buildings .

介绍了针对建筑物的生化袭击中常用的生化制剂。

And finally the binding proteins of different Bt in susceptible and resistant CBW strains were also compared .

并比较了抗、感品系棉铃虫中与不同Bt毒蛋白作用的结合蛋白的差异。

Airborne biochemical attacks and building environment security ( 3 ): relationship between dose of CBW agents and human responses

空气传播的生化袭击与建筑环境安全（3）：生化毒剂的剂量反应关系

Presents the basic concept of dose , main routes of CBW agents invading people , and common parameters of dose .

介绍了剂量的基本概念、生化毒剂侵入机体的主要途径和常见的剂量描述参数；

The results indicated that the relative soil moisture content from 0 % to 40 % is suitable for emergence of CBW moths .

研究结果表明，0%～40%的土壤相对含水量有利于棉铃虫的羽化。

We found susceptible CBW oviposited more percentage eggs on corn , but three treatments were less rate on soybean and peanut .

敏感品系在玉米上的产卵比率较高，而三个处理在大豆和花生上的产卵比率均较低。

A bioassay system to evaluate adult cotton bollworm ( CBW ), Helicoverpa armigera , behavioral responses to plant volatiles was described .

发展了一套测定棉铃虫Helicoverpaarmigera（H櫣bner）对植物挥发物的行为反应的生测系统。

More hatched larvae survived on corn and cotton . This means corn and cotton are perfect host for oviposition for CBW . 4 .

孵化的幼虫在玉米和棉花上存活较多，因此玉米和棉花是棉铃虫较为理想的产卵场所和生存寄主。

The results shows that Beauveria bassiana under natural conditions occurred at the fourth generation cotton bollworn ( CBW ) time in Anyang , Henan .

结果表明，河南安阳一带棉区自然条件下白僵菌多发生在四代棉铃虫发生期。

Asspraying of Brauveria bassiana at fourth generation CBW time is most effective , thus leading to the depression of the overwintering CBW population .

利用白僵菌防治四代棉铃虫效果最好，而且能降低棉铃虫的越冬种群数量。

The CCL of sequential damage for 3 times was 5 % of curled leave plants damaged by seedling aphids and 8 CBW of second generation and 6 CBW of third generation every 100 plants ;

相继3次为害的复合指标为苗蚜卷叶株率5%，棉铃虫百株幼虫2代为8头，3代为6头；

The results showed that after selection for 16 generations , the WLC 50 ( mean weight loss concentration ) of CBW to Bt transgenic cotton was 43 3 times as many as that of the 1st generation .

试验结果表明：经16代筛选，棉铃虫对转Bt基因棉的抗性倍数上升到433倍。

Models for calculating the fitness-acreage index , area capacity index of host plant and control pressure on cotton against CBW were proposed to quantify the source-sink relationship among host plants and optimize the control decision making of CBW .

为量化寄主间源&库关系与优化棉铃虫防治决策，建立了寄主适合性综合指数、区域性综合容量指数与棉田棉铃虫防治压力值分析方法与估测模型。

Since transgenic Bt cotton has been commercial planted in 1996 , cotton bollworm ( CBW ) ( Helicoverpa armigera ( H ü bner )) and other target insects have been controlled by it .

自1996年转基因棉花商业化种植以来，棉铃虫Helicoverpaarmigera（Hübner）等主要靶标害虫得到了很好的控制。

The major results are listed as follows : 1 . The taxis responses of M. mediator to different instars CBW larvae and cotton plant damaged by different instars CBW larvae were measured in a Y-shaped olfactometer .

主要结果如下：1、采用Y形昆虫嗅觉仪测定中红侧沟茧蜂对不同龄期棉铃虫幼虫及其危害棉株的趋性行为反应。

However , the tolerance and resistance of CBW to Bt cotton will be influenced under this high level selection pressure of Bt toxin . The resistance monitoring in long-term showed that the tolerance of CBW to Bt cotton has constantly increased in the filed .

然而，长期处于Bt杀虫蛋白的选择压下势必会影响到棉铃虫对Bt棉花的耐性和抗性，长期的抗性监测表明棉铃虫在田间对Bt棉的耐性不断增强。
