Abstract Full Text

The broadening of distribution of the invasive species Diabrotica virgifera virgifera Leconte in the area of Muntenia region under specific climatic and trophic conditions.


The spread of invasive species to a new area is influenced and conditioned by a number of drivers that can increase or control (meaning slow down) the speed of invasion. The largest shares in the factors which determine this area of spread are the geographical factors and the trophic and climatic conditions. For that reason, it is intended that immediately after the invasion, when pathways and vectors are determining which facilitated the invasion (early detection), to proceed with a monitoring program in order to develop and establish a management of control of the new pest. The present paper discusses on the possibility of developing the procedures for the surveillance work of maize crops in Southern and South-Eastern Romania to identify, monitor and evaluate the pest potential of Diabrotica virgifera virgifera. The research area included localities from counties in the Southern and South-Eastern Romania, where the monitoring was conducted with specific pheromone traps.
