In May 2013, more than 100 live cockroaches in the postal parcels from Germany were first intercepted by Beijing Entry-Exit Inspection and Quarantine Bureau. This event attracted extensive media attention. This article describes the current situation of keeping pet cockroaches worldwide, analyzes the risk of biological invasion of pet cockroaches, enumerates several foreign regulations for keeping or posting pet cockroaches, and gives some advices on the quarantine supervision for preventing the introduction of pet cockroaches. This article provides reference for better preventing the biological invasion of vectors of public health at frontier ports.

Objective To confirm whether one-time deployment of bromadiolone is effective in seaport rodent control. Methods Indoor and outdoor rodent density was investigated both indoor using powder tracking and night-trap Methods after saturated deployment of bromadiolone baits. Results The killing rates were 37.26% and 95.10%, in Mawei port, Fujian and in Dongjiang port, respectively. Conclusion One-time saturated deployment of a rodenticide in a sufficiently large area may yield satisfying killing effect.

Objective To compare the attracting effects of carbon dioxide (CO₂) traps with ultraviolet (UV) light traps on mosquitoes in field settings. Methods Both approaches were used within a 2-hour window before and after sunset, three times monthly, for six consecutive months. Results A total of 2483 mosquitoes were captured, of which 1544 were attracted by CO₂ traps and 939 by UV light. The density of mosquitoes captured by CO₂ traps (11.20/lamp·hour) was significantly higher than by UV light traps (6.87/light·hour). Conclusion The attracting effect of carbon dioxide traps was better than that of UV light traps. CO₂ traps can be used to effectively monitor mosquito density.

【Abstract】 Objective To master the species and seasonal fluctuation of mosquitoes, and provide scientific basis for mosquitoes control in Beijing ports. Methods CO2?baited trap and net trap methods were used for the surveillance of adult mosquitoes, and the scoop dipping method for the surveillance of larvae. Results A total of 14 270 mosquitoes were collected, belonging to 4 genera and 6 species. They were  Anopheles sinensis, Culex pipiens pallens,  Cx.tritaeniorhynchus,  Aedes albopictus, Ae.vexans  and  Armigeres  subalbatus.  As  many  as  114  mosquito  larvae  were  collected,  which  were  Cx.pipiens  pallens  and Cx.modestus. The dominant specie was Cx.pipiens pallens and its active peak was September. Conclusion The integrated management should be taken for a long time to control mosquitoes in Beijing ports.

【Abstract】 Objective To master the fly species and population composition at Beijing port and provide scientific evidence for fly control. Methods The baited fly traps method was used in this study. Results There were 30 species, 16 genera, 5 families of flies captured from April to November of 2006 and 2007. The annual average fly density was 59.7 flies/(cage ·day). There were two peaks, one was in May and the other was in September. Conclusion It was important to clean out the breeding sites for the control of flies at Beijing port.
