Pest species of Aphidomorpha and Coccomorpha (Hemiptera) on conifers urban areas of Ankara, Turkey

Abstract :

Due to the fact that coniferous trees are evergreen, they have a peculiar importance for the urban ecosystem. Apart from air pollution and other negative factors, they are susceptible to infestations caused by insects and other hazardous elements. For the purpose of establishing the species of Aphidomorpha and Coccomorpha (Hemiptera) seen on coniferous trees in Ankara Metropolitan Municipality urban green spaces, samples were collected from major parks, urban forests (Kazan, Beynam, Kızılcahamam, Oran) and also from street trees between the years of 2006-2016. As a result of the study, 13 species of Aphidomorpha –belonging to Lacninae (12), Adelgidae (1), and 13 species of Coccomorpha –belonging to Coccidae (3), Diaspididae (8), Pseudococcidae (1) and Matsucoccidae (1) were determined on coniferous trees. Of these species Physokermes piceae Schrank, 1801 on spruce trees, Torosaspis  cedricola (Balachowsky & Alkan, 1956)and Cinara cedri Mimeur, 1936 on cedar trees, Leucaspis pusillaLöw, 1883 on pine trees were found to be the most common species. Especially the first two species mentioned above were observed to cause the hosts to dry and die. Nemolecanim abietis Borchsenius, 1955 was recorded on Abies nordmanniana (Steven) for the first time. Information as to Matsucoccus pini (Green, 1925), one of the less-known species was also provided
