Cold acclimation and overwintering of female Aedes albopictus in Roma
Journal of the American Mosquito Control Association 22 (1), 149-151
Abstract: Eight years after the introduction and establishment of Aedes albopictus in Roma, females of the species extended their trophic activity to the coldest months of the year. Winter monitoring carried out from December 2003 to March 2004 in the urban area of the capital city of Italy recorded a weekly rate of positive ovitraps constantly around 30%, for the entire period of surveillance (14 wk). Eggs from ovitraps did not hatch when stimulated in laboratory with a wet and dry procedure. The hypothesis that long-lived female Ae. albopictus, belonging to the last seasonal generation, could have continued their trophic activity for 3 months, or that 1 or more cycles of reproduction have occurred in peculiar breeding sites, where a favorable microclimate may have allowed the development of at least 1 larval generation, are discussed and compared with the existing literature.
