Seed and Wasp Production in the Mutualism of Figs and Fig Wasps

Figs (Moracea: Ficus) and fig wasps (Hymenoptera: Chlocloids: Agaonideae) depend on each other to complete their reproduction. Monoecious fig species and their pollinating wasps are in conflict over the use of fig ovaries which can either produce one seed or one wasp. From observation on Ficus virens Ait., we showed that female flowers with outer layer of ovaries (near to the wall of syconium) had no significant difference from that with inner and interval layer of ovaries (near to the syconium cavity), in which most seeds and wasps were produced. This meant that fig tree provided the same potential resource for seed and wasps production. Observation indicated that there was usually only one foundress in syconium at female flower phase and no com- petition pollinators. Measurement of the style length of female flowers and the ovipositor of pollinators indicated that most ovaries could be reached by pollinator’s ovipositor. However, at the male flower phase, production of seeds was significantly more than that of wasps including non-pollinating wasps but there was no significant difference between seed and pollinating wasp production when without non-pollinating wasps produced. This result indicated that non-pollinating wasps competed ovaries not with seeds but with pollinating wasps for ovipositing. Bagged experiment showed that the sampling fig species was not self-sterile which was important for figs and wasps to survive bad season. Seed production in self-pollinated figs was not significantly different from total wasps in- cluding non-pollinating ones. This might be related with the weaker competition among wasps since bagged figs were not easy to reach by wasps from outside.

SCISSORS DIFFERENCE AND ITS IMPACTS ON ECONOMIC VALUE OF CULTIVATED LAND IN CHINA

The problem of price scissors difference between industrial products and agricultural products is one of the important problems in China. It impacts not only the living standard improvement of farmers but also the economic value of cultivated land, furthermore results in the direct and indirect loss of cultivated land resources. China＇s cultivated land area has decreased dramatically in recent years. An important reason for the decrease is the relatively low cost of cultivated land occupancy, which results from the distortion of economic value of cultivated land due to the existence of scissors difference. This study firstly analyzed the dynamic change of scissors difference and calculated the absolute and relative magnitude of scissors difference from 1997 to 2002, then computed the economic value of cultivated land before and after scissors difference adjustment in 2002, and finally discussed the inverted scissors difference. Results suggest that the scissors difference has a remarkable impact on the economic value of cultivated land, and the adjustment of scissors difference even inverted scissors difference to the economic value of cultivated land is indisoensable.

Ecological Security Assessment in County Area Based on P-S-R Model——A Case Study of Ningwu County,Shanxi Province

To further understand the status quo and change tendency of ecological security in county area, we took the example of Ningwu County, the headstream of Fenhe River, confronting serious eco-environment problem and considerable human impacts. Taking Ningwu as the study area and using variation coefficient method to determine the weights of the indices, we built ecological security pattern based on Pressure-State-Response （P-S-R） Model of Organization for Economic Cooperation and Development. The ecological security status was evaluated by calculating eco-security index （ESI） with socio-economic statistical data of Ningwu during 2001 -2010. The results showed that the situation of eco-security had been improved from heavy alarm to relative safety during 2001 -2010. It reflected that the ecological economic system in Ningwu County tended to be relaxed constantly after experienced a sharp conflict between ecological environment and economic growth. The ecological safety awareness was growing, however, by force of the objective requirements of population growth and economic development, the situation of ecological security was still unstable.

China's 60 years of industrial transformation reviewed

In China, the real industrialization and modernization process started in 1949, when the Chinese people were emancipated from the yoke of the Kuomintang and the People's Republic of China (P.R.C) was founded. However, the road of emancipation has been a bumpy one. In particular, the emancipation of the mind has often been full of twists and turns. The tremendous liberation of social productive forces originated in the emancipation of the mind, whose truth has been tested by economic development practices. In the past 60 years China has paid tremendous efforts and costs in pursuit of emancipation, and today it still needs to emancipate the mind anew. For 60 years, since the formation of P.R. C, the country has kept pursuing the emancipation of the mind while exploring ways of change in institution, strategy and policy. In the first 30 years China attempted to devise an idealistic approach of transition to the socialist planned economic system, which was characterized by continuous revolution and movement. In the second 30 years China explored a realistic approach of transition to the socialist market economic system, which is characterized by incremental reform and opening-up. For six decades industry has remained at the forefront of transformation. The emancipation of the mind and the realization of change aim to ultimately make China a strong nation with an affluent people. The purpose of the six-decade struggle in new China is to erase the stigma of "being poor and blank," secure a firm and strong foothold in the world, restore China's status as a world power and let the Chinese people enjoy the affluence and welfare of a well-off society. The central mission of this national revitalization is to realize industrialization. Therefore, industrialization has been the central theme of China's revitalization in the past 60 years. After 60 years of industrialization, hundreds of millions of Chinese people are now able to enjoy ever-increasing wealth from industrial civilization. However, still a larger proportion of China's 1.3 billion people are awaiting industrial civilization. In this sense, industrialization is not only the focus of China's socioeconomic development but also the world's largest livelihood mission. Industrial development is more of a means of enhancing people's livelihood than a means of regaining the title as a world power. This will become one of the distinctive characteristics of China's industrialization in the new stage.

Knowledge of, attitudes towards, and practice relating to schistosomiasis in two subtypes of a mountainous region of the People’s Republic of China

Background:Schistosomiasis japonica is still endemic in the People’s Republic of China(P.R.China)in five provinces of lake and marshland regions and in two provinces of mountainous regions.Studies elucidated that individual and community perception,attitudes towards schistosomiasis,and hygiene behaviors were crucial factors for preventing schistosomiasis.This study sought to assess the knowledge of,attitudes towards,and practices(KAP)relating to schistosomiasis in two subtypes of a mountainous region in Eryuan County,Yunnan Province,P.R.China.The study’s aim is to make suggestions for establishing more specific and effective control measures for disease transmission and interruption in two subtypes of a mountainous region with low-level infection rates.Methods:A cross-sectional study of 3,000 inhabitants was carried out in the Yongle(plateau basin)and Xinzhuang(plateau canyon)communities of Eryuan County,Yunnan Province in November and December 2011.Stratified cluster random sampling was undertaken using a uniform set of quantitative questionnaires administered by trained assistants.This was further supported with qualitative data from in-depth interviews(IDIs)conducted with ten farmers and ten students.All participants were examined for schistosomiasis using both a serological test(indirect hemagglutination assay[IHA])and a stool examination(Kato-Katz).Results:The total schistosomiasis knowledge rate in Yongle(83.4%)was significantly lower than that in Xinzhuang(95.5%).In both communities,among the respondents aged 15 years or below,more than one third didn’t know the name,endemic areas,and animal reservoirs of schistosomiasis.The majority of respondents in Eryuan acquired their schistosomiasis knowledge from doctors,followed by handouts and hearing from others.The infection rate was once the highest in Yongle,but is now the highest in Xinzhuang,where there are more risk factors for schistosomiasis,such as frequently grazing cattle,digging vegetables or cutting grass in the field,as well as raising cattle by free grazing.Conclusion:In short,Eryuan County’s overall knowledge rate of schistosomiasis was found to be high.Due to various dominating risk factors,different control strategies should be designed keeping in mind the two different subtypes of endemic areas for schistosomiasis in mountainous regions,namely plateau basins and plateau canyons.
