Abstract: After a report of mosquito nuisance and collection of live Culex quinquefasciatus mosquitoes on board of a passenger aircraft from Africa to Amsterdam, a mosquito surveillance was carried out in 38 cabins of passenger aircraft from overseas airports immediately after landing at Amsterdam Schiphol airport, the Netherlands (2010 and 2011). Live mosquitoes were collected in 10 aeroplanes, belonging to the species Culex quinquefasciatus (n=9), Culex antennatus (n=2), and Aedes mcintoshi (n=1). All mosquitoes were collected in aeroplanes that came from airports located in Africa. Disinsection is discussed. Journal of the European Mosquito Control Association 32: 17-21, 2014

Abstract: Six gel-and five water-transported Dracaena braunii shipments originating from the South coast of China were screened for exotic mosquito species during a surveillance project on exotic vectors in Belgium. In November 2013, a live Aedes (Stegomyia) albopictus larva was detected in a gel substrate. This is the first direct evidence of the importation of Ae. albopictus on gel-transported Lucky bamboo. It also confirms that the importation risk of Ae. albopictus by transport of ornamental bamboo plants remains. In addition to the registration of appropriate biocides, a structured and permanent surveillance programme is needed in Belgium to allow for the early detection of invasive mosquito species and the timely implementation of control measures.

Abstract: In January 2013, a female mosquito collected during the week 18th-25th July 2012 in Lelystad (The Netherlands) during routine national vector surveillance was morphologically identified and genetically confirmed as the Asian bush mosquito, Aedes japonicus japonicus. In order to assess the extent of the infestation area, subsequent extensive mosquito surveillance in the surrounding area during 2013 consisted of visual inspection of potential habitats and adult trapping in increasing radially around the location of the initial finding. This surveillance confirmed the existence of a widely established population of Ae. j. japonicus in the municipality of Lelystad. Despite this detection, it was decided not to implement any mosquito control measures for two reasons: this would require large scale biocidal treatment and community participation in order to be effective, and this species is not a confirmed vector of disease agents in the field. As an alternative, it was decided that community information would be provided to enable management measures such as larval habitat source reduction.

Abstract: Mass-occurrence of floodwater mosquitoes, mainly Aedes sticticus, in the River Dal\älven floodplains in central Sweden has caused public health issues and economic losses for many decades. In the summer of 2000, the problem escalated and the Biological Mosquito Control project was initiated with the aim of reducing mosquito nuisance. Larviciding, based on Bacillus thuringiensis israelensis (Bti), was chosen as the optimal method. However, high abundance of blood-seeking floodwater mosquitoes after Bti-treatments on some occasions raised questions about the effectiveness of the treatments. This study evaluated the effect of Bti-larviciding on abundance of larval and adult floodwater mosquitoes in four selected study areas, each represented by a CDC-trap site and a 5 km radius. The four areas differed with respect to their mosquito control history and the coverage of larval habitats with Bti-larviciding. The Bti-treatments provided a significant reduction of mosquito larval abundance, and normally 100\% reduction was achieved. Thus, high abundance of blood-seeking mosquitoes could not be explained by insufficient larval control by Bti. However, a significant negative correlation was found between high numbers of blood-seeking floodwater mosquitoes and the coverage of larval habitats with Bti-larviciding within 5 km around the trap site. Consistently low numbers of mosquitoes (less than 1000 per trap/night) were only found in the two areas with high treatment coverage of larval habitats (97-100\%). Evaluating the mosquito control efficiency showed that larval habitat coverage of at least about 95\% is required in order to accomplish consistent low floodwater mosquito numbers. The conclusion from this analysis is that the coverage of larval habitats with Bti-larviciding in parts of the River Dal\älven floodplains has to increase in order to guarantee an improvement of the public health problems caused by Aedes sticticus and other floodwater mosquitoes to both humans and animals in the region.
