[ Method ] Using fixed system survey method, with fruit fly attractants as the materials, the occurrence dynamic of oriental fruit fly adult in guava orchard was investigated. The control effects of the methods such as fruit fly attractants, fruit bagging, cleaning park to pick up fallen fruit and timely spraying pesticide against the pest were also studied. [ Result] Oriental fruit fly had two damage peak periods in Nanning region of Guangxi Prov- ince (May to June, August to September). Through the integrated control measures of trapping agent for male flies, timely spraying, fruit bagging and cleaning park to pick up fallen fruit, the population density in guava orchard dropped significantly. The fruit damage rates of guava in research base were only 6.67% -7.33% during the peak period of oriental fruit fly in June 2008, while they were 90.53% -98.00% in control area, obtaining good control effect against the pest.

And the regression model was built. Finally, the regression model was tested on the basis of the data in Jianshui County of Yunnan Province during 2004-2006.[Result] The main meteorological factors that influenced the occurrence of oriental fruit fly were relative humidity, the lowest monthly temperature and rainfall.

[ Method] The indoor infection test and field control test of Pyemotes sp. against oriental fruit moth was carried out. The parasitic ability and activity characteristic of Pyemotes sp. were observed, and the effect of environmental factors such as humidity and temperature on the para- sitic ability of Pyemotes sp. was studied. [Result] Pyemotes sp. had good control effect on oriental fruit moth under the proper conditions; the host searching abili- ties of Pyemotes sp. were different at different temperature and humidity conditions, humidity had large impact on the activity of Pyemotes sp., while temperature had large impact on the individual activity.

[Method] The bulb scales of the test-tube plantlets of Tiber, Rodina and Constanta were cul- tured in media supplemented with different cytokinin and auxin at different concen- tration, and then the adventitious buds in each treatment were calculated. [Result] Cytokinins had different influence on the adventitious bud differentiation of the three oriental lily cultivars. Among them, 6-BA had the best effect to induce the adventi- tious bud differentiation from bulb scales of Tiber and Rodina, but there was some difference in the optimal concentration. KT had the best effect to induce the adven- titious bud differentiation of Constanta. The auxins had little influence on the quality of the adventitious bud of the three oriental lily cultivars, but caused some difference in differentiation coefficients. [Conclusion] The most suitable media for the adventi- tious bud differentiation from bulb scales in vitro of Tiber, Rodina and Constanta were MS+0.2 mg/L 6-BA+0.2 mg/L 2,4-D, MS+I.0 mg/L 6-BA+0.2 mg/L IAA, MS+ 1.0 mg/L KT+0.5 mg/L 2,4-D, respectively.展开更多

English teaching is indispensable due to the uniqueness of Chinese language and culture, and our open policy. College English teaching has become an extremely important platform, different from most other countries, to train talents. And to train talents is not only to train for the English language speakers or to be just certain technicians. This article will, from aspects of teaching philosophy, theory and mode, give a preliminary probe into the reasons why humanistic education should show itself up in all segments of college English teaching and how to show up. And it is expected to use the little to get the big.展开更多
