A contribution to the aphid fauna of Greece
Tsitsipis, J. A.; Katis, N. I.; Margaritopoulos, J. T.; Lykouressis, D. P.; Avgelis, A. D.; Gargalianou, I.; Zarpas, K. D.; Perdikis, D. C.; Papapanayotou, A. (2007)In the present study a list of the aphid species recorded in Greece is provided. The list includes records before 1992, which have been published in previous papers, as well as data from an almost ten-year survey using ... -
Efficacy of pymetrozine against Myzus persicae and in reducing potato virus Y transmission on tobacco plants
Margaritopoulos, J. T.; Tsamandani, K.; Kanavaki, O. M.; Katis, N. I.; Tsitsipis, J. A. (2010)Forty-four parthenogenetic lineages of Myzus persicae s.l. (Sulzer) from tobacco crops and peach orchards located in various regions of Greece were examined to determine their response to the insecticide pymetrozine using ... -
Insights into the genetic diversity and evolution of Little cherry virus 1
Katsiani, A. T.; Maliogka, V. I.; Amoutzias, G. D.; Efthimiou, K. E.; Katis, N. I. (2015)Little cherry virus 1 (LChV-1), a member of the recently proposed genus Velarivirus, is a sweet cherry pathogen that has been recently reported to infect other Prunus species and is associated with various plant disorders. ... -
Molecular Analysis of the Coat Protein of Potato virus Y Isolates in Greece Suggests Multiple Introduction from Different Genetic Pools
Margaritopoulos, J. T.; Dovas, C. I.; Gounaris, J.; Skouras, P. J.; Kanavaki, O. M.; Katis, N. I.; Tsitsipis, J. A. (2010)The phylogenetic relationships among Potato virus Y (PVY) isolates from northern and southern Greece were investigated.

Transmission of Potato virus Y in tobacco plants by Myzus persicae nicotianae and M-persicae s.str
Kanavaki, O. M.; Margaritopoulos, J. T.; Katis, N. I.; Skouras, P.; Tsitsipis, J. A. (2006)The transmission efficiency of Potato virus Y-N (PVYN) from and to tobacco plants by Myzus persicae nicotianae, a tobacco specialist, and M. persicae s.str. (Hemiptera: Aphididae), a generalist, was evaluated. In direct ... -
Transmission of Zucchini yellow mosaic virus by colonizing and non-colonizing aphids in Greece and new aphid species vectors of the virus
Katis, N. I.; Tsitsipis, J. A.; Lykouressis, D. P.; Papapanayotou, A.; Margaritopoulos, J. T.; Kokinis, G. M.; Perdikis, D. Ch; Manoussopoulos, I. N. (2006)Nineteen aphid species were tested for their ability to transmit Zucchini yellow mosaic virus (ZYMV) from and to zucchini under laboratory conditions. Sixteen species were found to be new vectors of ZYMV (i.e. Aphis craccae, ... -
Two diseases of dimorphotheca caused by lettuce mosaic potyvirus and tomato spotted wilt tospovirus
Manoussopoulos, I. N.; Chatzivassiliou, E. K.; Smyrnioudis, I. N.; Katis, N. I. (1999)In 1997, virus-like symptoms were observed in dimorphotheca plants (Dimorphotheca sinuata) at two different locations in Greece. In a greenhouse near Heraklion (Crete), plants showed chlorotic patches mainly in the older ...
