Assessment of the current situation on newly introduced potato and tomato pest in Armenia

Generation Index of potato moth Phthorimaea operculella in Armenia Field assessment showed that there were two new species introduced to Armenia that are difficult to distinguish visually, but have different biology: potato tuber moth (P. operculella) and tomato leaf miner (T. absoluta). link full report
Monitoring of the actual distribution of the two moth species P. operculella and T. absoluta separately is recommended by collocating pheromone traps in the potato and tomato cultivation areas below 1300 m above sea level.
Population development model based on meteorological data showed that potato storages and tomato greenhouses are the only places where potato moth (P. operculella) might persist over the years, since under outdoor temperatures the pest hardly survives during winter time. Therefore, effective control in storage and greenhouse is essential to reduce the population and to avoid a fast increase in the coming cropping season.
