Conclusions of mosquito control of Szeged in 2011

Conclusions of mosquito control of Szeged in 2011- 2011-ben Szeged szúnyoggyérítéséből készült poszter következtetései

- The application of satellite imagery and GIS (geographic information systems) in the mapping of mosquito breeding sites turned out to be very useful for the identification of areas covered with water and for field sampling data management.

- In 2011, 91 mosquito breeding sites were explored and monitored at 359 sampling points in Szeged.

- The main mosquito breeding sites were contaminated oxbows with reed vegetation and rainwater channels.

- The majority of inland excess water formed after the springtime rainfall did not turn into mosquito breeding sites.

- Due to the effective biological larvae control and the lack of springtime-flood, the scale of mosquito harm was significantly lower in 2011 than in 1999.

- Due to the lack of springtime-flood, the ratio of floodwater mosquito species in the mosquito assemblages of Szeged decreased considerably in 2011.

- The investigation in 2011 revealed species not reported previously in Szeged: Anopheles maculipennis (Meigen, 1818); Anopheles claviger (Meigen, 1804); Anopheles atroparvus (Van Thiel, 1927); Coquillettidia richiardii (Ficalbi, 1889)

- Invasive dangerous mosquito species (Aedes albopictus etc) have not occurred yet in Szeged.

- In the ?Black water? area of the Gyálai Dead Tisza oxbow, the majority of larvae lives in the 20-30 cm band of the open water in front of the reed as well as in the area of rare reed. These habitats can be effectively treated by biological agents from the side of the water with high-pressure sprayer.

- The biting activity of mosquitoes reached its maximum 30 min after the sunset then terminated in another 20 min.
