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。

During light adaptation, the diameter of rhabdoms was small, the arrangement of microvillus in the distal rhabdom was in disorder, and the area of the multivescicular bodies in the cytoplasm of the retinular cells was large, but the perirhabdomal vacuoles was very small, the amount of the lamellar bodies and mitochondrias were small, the pigment granules were distributed in all retinular cell.

结果显示：光适应时感杆束的直径较小，组成近远端感杆束的微纤毛排列零乱；小网膜细胞中的多囊体体积增大，膜下储泡囊体积减小，板膜体、线粒体等细胞器数量较少，色素颗粒分布于整个小网膜细胞。

With the found of new Rhizobium resources and development of science and technology,Rhizobium taxonomy has transfer from tradition classification to modern systematic taxonomy.

In order to prove the accuracy of GPS observation, water vapor radiometers were used to observe together with GPS. Comparison between WVR and GPS observations at different sites and times shows that rootmeansquare error is less than 4 mm. Therefore, the slant path water vapor amount can be accurately retrieved using this method, which is suited for nearly realtime remote sensing and detection of the atmosphere.

为验证GPS观测结果精度，用微波辐射计与GPS一起进行了联合观测，不同观测地点和时间的对比结果表明，二者rootmeansquare误差小于4mm，证明应用此种方法地基GPS可较精确地反演出倾斜路径方向大气水汽总量，而且这种反演方法适合于近实时大气遥感探测。
