Assulta and the induction of GST activity by nicotine and capsicine in H. assulta provided partial supports for the hypothesis that diet breadth was governed by detoxification abilities. The results also indicated that two sibling species had different strategies of adaptation to toxic substances: H. assulta saves expenditure of nutrients and energy by restricting their countermeasures to a few potentially toxic compounds. H. armigera, by contrast, must be prepared to counter a wider range of potential toxins. 5. Compared with parental species, hybrids of reciprocal hybridization had significant difference in feeding preference for hot pepper.

结果显示，广食性的棉铃虫在中肠羧酸酯酶和谷胱甘肽-S-转移酶活性方面高于寡食性的烟青虫，但烟青虫谷胱甘肽-S-转移酶活性可以被寄主植物内的烟碱和辣椒素所诱导，表明解毒酶活性在一定程度上影响着植食性昆虫的食性广度；同时也暗示着二近缘种对有毒的次生物质采取不同的适应策略：烟青虫有选择地对付种类较少的植物次生物质以减轻营养和能量的消耗；棉铃虫则必须对付存在于其寄主植物内的种类繁多的有毒次生物质。

The symptoms involved were vein-clearing, yellow or green veinbanding, typical mosaic, rugosity of leaf lamina, dwarfing and rosetting.

第一型在烟农特400号和心叶烟上不引起花叶，而第二型在烟和心叶烟上都能引起系统性花叶。

The density decreasing of B.germanica in field trial by using the smoke was(96.79%).Conclusion The testing method is simple and practical,and with the characters as easy ignitability,safety to deposit and transport,the smoke generator is good to generalize.

该烟剂质量指标测定方法简单易行，符合烟剂技术指标与实际应用要求，测试亦揭示该烟剂具有易引燃、运输与储藏安全以及有较高药效等特点。

Results Nicotinamide at 1-5 mg/ml induced apoptosis of GLC-82 cells in a dose-dependent manner, and group 4 mg/ml and group 5 mg/ml showed increased apoptosis than other groups. Distinct morphologic changes of cell apoptosis such as karyopyknosis and conglomeration were observed; Cell migration became slower as the dosage of Nicotinamide increased;Cells produced an arrested at G1 phase, accompanied by a reduction of cells transiting through S phase.

结果 烟酰胺诱导细胞凋亡程度与用药剂量呈正相关，较高剂量的药物能引起GLC-82肺腺癌细胞呈现边界不清，体积缩小，核固缩，染色质凝集、边缘化，甚至细胞发生破碎，凋亡小体形成；随着烟酰胺浓度的增高GLC-82细胞向划痕区的愈合速度不断减慢；烟酰胺的浓度大于等于3 mg/ml 时，细胞周期主要表现为G1 期比例的上升伴随S期比例的下降。

To reveal the pyrolysis products of the alkyl malonic acids, three types of cigarettes were prepared.

在混合型卷烟配方中，香料烟起着丰富烟香，连接白肋烟和烤烟香气的桥梁作用。

The character of flower colour and high nicotine conversion inherited steadily,the average nicotine content of their offsprings decreased,while nornicotine content increased significantly.

通过对发现的5株白肋烟B37花色突变株后代的连续观察与研究，结果表明，5株白花突变株当代均为高烟碱转化株；随着世代的增加，白花后代群体花色遗传稳定，高转化率性状更趋于纯合；烟株群体的平均烟碱含量明显下降，降烟碱则明显上升，烟株群体生物碱表现为以降烟碱为主。

The synergism ratios of piperonyl butoxide to alpha-cypermethrin in these three strains were similar(about 20-fold), which suggested metabolic detoxification probably confers about 20-fold inherent resistance in the B-type whitefly, as PBO is a mixed function oxygenase and esterase inhibitor and glutathione S-transferase is not affinity to resistance in B. tabaci. The synergism ratio of triphenyl phosphate to alpha-cypermethrin in the NJ strain was 12-fold, which implied the synergism of PBO in the B-type whitefly is mainly due to inhibiting esterase activity.

增效试验表明PBO对这三个品系的增效作用均为20倍左右，因为在烟粉虱中PBO即是多功能氧化酶抑制剂，也是酯酶抑制剂，而谷胱甘肽S-转移酶与抗性无关，因此推断代谢酶在B型烟粉虱对高效氯氰菊酯的抗性发展中起到的相对作用可能为20倍左右，而且这种抗性是B型烟粉虱天生的；TPP对NJ品系的增效作用为12倍，说明PBO增效作用主要是由于抑制酯酶而引起的，即代谢抗性大部分由酯酶所贡献。

Bioassaying of squash silverleaf assigned the whitefly from Beijing (host: cotton and sweetpotato) and Xinjiang to B biotype. However, populations from Fujian and Guangxi without silverleaf symptom were considered as non-B biotype.

银叶生测实验表明：北京甘薯、棉花和新疆茄子上的烟粉虱为害西葫芦后可引起寄主的银叶，表明属B型烟粉虱；福建甘薯和广西南瓜上的烟粉虱种群在西葫芦上为害不呈银叶属非B型。

Sulfuric acid was sulphonation reagent, add the sulfuric acidquantity was 8%, reaction temperature was 60~65℃.The reaction occursbetween the feed oil and sulfuric acid,then add 30% of sodium hydroxidesolution conducted neutralization in the Pyrex standard react kettle,when the reactionfinished ,draw out the products by funnel,then the products react with 8%clay to refine received the sulphonation refining oil so as to review property andreceive rate of the shallow sulphonation refining oil .By the using the sulphonationrefining oil to blend lubricant,its quality is on-specification .

为验证其可行性，首先在实验室进行浅度磺化小试，原料油采用新疆原油经常压蒸馏、减压蒸馏、溶剂精制、溶剂脱蜡后的减压二、三线脱蜡油，发烟硫酸作为磺化剂，发烟硫酸加入量8%，反应温度60～65℃，用三口圆底耐热玻璃标准反应釜对原料进行发烟硫酸磺化，加入量30%氢氧化钠中和，分液漏斗抽提，在烧杯内加入量8%白土进行精制得到磺化抽余油，考察浅度磺化抽余油性质和收率，用磺化抽余油调合润滑油质量合格。

The results showed: 1 RN didn't the leaf width,leaf long,leaf area,yield,productive value and average price of flue-cured tobacco,but had significant effect on grad composing,content of chemical component and the accumulation of N,K and Cl.Within limited rang of RN,the relations between yield,average price,yield of high grad tobacco,yield of low grad tobacco,nicotin,N,reducing sugar,Cl,amylum,volatile base and the quotient of ammonium would been described by significant quadratic polynomial,and the relations between K and the quotient of ammonium conformed to negative linear equation;2With a RN of 75%∶25%,the value of proportion of high and middle grad tobacco,content of nicotin,N,K,uptake of N and K/Cl were the highest,volatile base was lowest.

结果表明：1RN对烤烟的农艺性状、产量、产值、均价等没有明显影响，而对烤烟的等级结构、内在化学成分含量、氮、钾、氯的吸收量有着显著影响，可以用显著的二次多项式模型或直线相关方程描述产值、均价、上等烟产量、下等烟产量等经济性状以及烟碱、总氮、钾、还原糖、氯、淀粉、挥发碱等内在化学成分的含量与铵态氮份额之间的关系；2RN为75%∶25%时，中上等烟比例、烟碱、总氮、钾、钾氯比、氮吸收量最高，挥发碱含量最低。
