The gypsy moth, Lymantria dispar, is an important economic pest that causes large-scale damage to forests worldwide. Because of its important role in initiating and controlling insect behavior, olfaction—and olfaction-based pest management—has drawn increasing attention from entomologists. In this study, we identified the gene that encodes the olfactory receptor co-receptor (OrCo). Through amino acid sequence alignment, we found that LdisOrCo shares high identity with other OrCo proteins from different insect orders. Next, we performed RNA-interference (RNAi) to assess the role of OrCo in olfaction. Electroantennographic assays showed that after RNAi, the average value of males’ response to sex pheromones was 0.636 mV, significantly lower than that of the positive control (average = 1.472 mV). Females showed no response to sex pheromones before or after RNAi. Finally, quantitative PCR showed a strong decrease in the expression of OrCo after RNAi, by ~74% in males and by 23% in females relative to the positive controls. These results indicate that OrCo is not only critical to odor recognition, but it may also represent a new target for development of semiochemicals that can influence insect behavior. © 2015 Ivyspring International Publisher.

In the overall landscape of risk management in China, enterprise legal risk management can be singled out as a prominent development in the recent years. This development reflects the dramatic changes to the domestic environment within which the Chinese companies operate and the progress the Chinese companies made when they interacted more closely with international partners. In this article we analyze the concepts, tools and the relative standards about legal risk management. We also look at the legal risk management in Chinese companies by studying a concrete case of implementation of legal risk management system in a large State Owned Enterprise. While doing that, we highlight some of the general features of legal risk management implementation of the Chinese market. © 2015 Taylor & Francis Group, London. Source

The current status and the disaster risks the information systems faced are analysed in this paper. Combined with domestic and international status of technological developments in the field of information systems disaster recovery, disaster recovery needs and disaster recovery objectives, the primary and disaster recovery system construction framework based on the database replication techniques is designed. The architecture has been used in the domestic to implement the remote disaster recovery system construction, and the successful switch proves the reliability of the architecture. © 2010 IEEE.

Currently the reliability of rotating equipments in typical petrochemical plants, such as turbo machineries, centrifugal compressors, reciprocating compressors, fans, pumps, etc. plays an important role in a long-term operation of the plants. The important tasks for management technology research of rotating equipments are to build a new type of maintenance management platform and take an advantage of the reliability analysis technique for fault diagnosis and maintenance strategy optimization. In this paper, firstly, the development of maintenance management technology in China and overseas was introduced. The problems of traditional reliability analysis techniques were pointed out. Secondly, the key technologies of the new type of maintenance management system were introduced. Furthermore, the structure and work process of the new type of maintenance management system were proposed. Finally, the key contents and functions of this system were given.

The guava fruit fly, Bactrocera correcta (Bezzi) (Diptera: Tephritidae), is an invasive pest of fruit and vegetable crops that primarily inhabits Southeast Asia and which has the potential to become a major threat within both the Oriental and Australian oceanic regions, as well as California and Florida. In light of the threat posed, it is important to know the potential geographic distribution of this pest in quarantine work in order to provide an early warning and to prevent its widespread invasion effectively. In this study, the eclosion rate model was constructed from empirical biological data and analyzed using stepwise regression, based on the soil temperature and moisture data of Chinese meteorological stations, and mapped with ArcGIS. Using this information, the potential geographic distribution of B. correcta from January to December in China was predicted. The results showed that most regions in China were optimally suitable for B. correcta from May to September. Monitoring measures in the north parts of China should be taken from April to October, and as for Guangdong, Guangxi, Yunnan, and Hainan provinces, the measures should be strengthened through the whole year. © 2015, The Japanese Society of Applied Entomology and Zoology.
