Tiger Mosquitoes Under Control in Cesena
The results were presented at the 5th European Mosquito Control Association Workshop, Turin, Italy. (Engelbrecht et al. (2009) Continuous trapping of adult Asian tiger mosquitoes (Aedes albopictus) with BG-Sentinel traps reduced the human landing rate and density indices in an urban environment in Cesena, Italy. Oral presentation at the 5th European Mosquito Control Association Workshop, Turin, Italy, 12 March 2009. Session 10.5.)
Queensland Australia Headed for Worst Dengue Outbreak in Years
The escalation in numbers of dengue fever cases is the quickest its been in over 5 years. In Decemer alone, there have been over 50 cases with several people being hospitalized.
This outbreak is affecting many suburbs in the North Queensland area. A medical entomologist from Queensland Health said that the season has started 2 months earlier than usueal suggesting one of the worst outbreaks they have seen in years.

Singapore’s Fight Against Dengue Fever
In 2008, Singapore confirmed 6,424 cases of dengue or dengue hemorrhagic fever. While this is an extremely large number it is actually 2,183 cases fewer than in 2007. The National Environment Agency has claimed that the decrease in cases is due to an extensive fight against the Aedes mosquito.
It was predicted that Singapore would experience major dengue outbreaks in 2008. Instead of going up the number of cases actually decreased, due to an estimated US$137,000 a day spent on fighting the vectors and prohibiting them from breeding.

The risk of Chikungunya and Dengue outside of the tropics:
can a tiger mosquito trap help reduce the risk?
Chikungunya fever and Dengue fever have long been a problem of the tropics and subtropics. The more temperate regions of the world were considered safe and without risk, but this has changed.
A mosquito capable of transmitting Dengue and Chikungunya has been spreading into many regions of the world: large parts of Europe and the Americas are now infested by the Asian tiger mosquito (called Aedes albopictus by scientists). International trade and travel, the species’ remarkable adaptation to the urban environment, and a combination of global warming and the acclimatization to cooler climates are paving the way for a continuous spread of the Asian tiger mosquito.
- Risk of the presence of a person who is infected with the Chikungunya virus or Dengue virus.
- Risk of transmission of the respective virus by insect disease vectors such as the Asian tiger mosquito (Aedes albopictus). The larger the tiger mosquito population, the larger the risk.
