Spatial and Temporal Dynamics of Aedes albopictus Populations in Rural and Agricultural Areas in Chania, Greece, After Its Invasion

Aedes albopictus , also known as the Asian tiger mosquito, is an aggressive invasive mosquito species that transmits parasites cause several major human diseases such dengue, Chikungunya, and Zika. Its recent establishment in many European countries reported autochthonous cases of -transmitted arboviral highlight importance effective surveillance programs to plan implement efficient mosquito-control interventions. invaded Greek island Crete 2014 rapidly spread throughout; however, there are no comprehensive population-related data yet available. Our study focused on spatial temporal dynamics Ae. populations rural agricultural areas Chania (western part Island). An oviposition network, consisting 51 ovitraps, was established 2017 systematically inspected for 2 years. Thirty ovitraps were 21 surrounding areas. Eggs collected weekly transferred laboratory counting assessment hatching rates. The egg distribution assessed by using geographical information systems statistical analysis tools. Kernel density hot spot employed identify clusters high eggs. Oviposition activity (eggs traps) recorded during April–May December (of both years), while maximum egg-laying rates observed September–October. proportion traps with eggs similar between areas, higher number compared 2017. Egg hatch (>90%) until end September. diapausing non-hatched increased at November. All hatched larvae identified Albopictus indicating a negative effect invasion population local cretinus .
