Abstract
As a result of increased trade, transportation, and globalization, the phenomenon of growth regarding the entrance of invasive alien species (IAS) represents a serious concern (including flora, fauna, and microbiota). Acanalonia conica (Say, 1830), also known as the green cone-headed planthopper (GCHP), was first identified in the Chrysanthemum collection of the Botanical Garden in Iaşi, Romania. The principal objectives of this article are to update the limited data on the presence of A. conica in Romania, revealing its occurrence in new areas (East Romania, Iași) and on other host plants that were not previously documented in the United States and Europe, as well as to establish the trends of population evolution, with an emphasis on the peak of GCHP population development during the life cycle on East Romania indoor conditions. The evolution of the GCHP population was established using the recorded data on total counts of adults and nymphs observed from a limited area (greenhouse compartment), checked every two days in 115 days of direct observations. The peak of population was established at late-July (25th to 31st day of the month, 30th week of the year) for the conditions of East Romania and it was the appropriate time to monitor the activity of the species, to estimate the damages in specific crops, and to initiate the specific pest control measures. Current findings are significant not only for the general spread of this species in Europe and in Romania but also for the observations regarding new hosts and the population evolution in a greenhouse habitat for the cultivation of ornamental plants.
