and The mildness of the last winter says a number, it seems, higher adult insects active in early summer. “Temperatures of -10 degrees in the winter to allow eradication, but this was not the case this year “, explains Frédéric Francis, professor at Gembloux Agro-Bio Tech. Moreover, the combination of the heat currently identified and recent rainfall provide the ideal conditions for the development of insects.
“The high temperatures and the recent rains are going to be working to an acceleration of the biological cycle,” says the Pr. Francis. “In the case of the mosquito, there is a three week cycle with a temperature of 22 degrees. If the thermometer rises to 30 degrees, the duration of the cycle is reduced. And when you know that a female lays 20 to 30 eggs per day, it quickly becomes exponential. “
