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
