    Distribution and activity period of the invasive Orosanga japonica (Melichar, 1898) (Hemiptera: Ricaniidae) in Turkey
    (Taylor & Francis Ltd, 2020) Karatas, Ahmet; Karatas, Aysegul; Yavuz, Nizamettin; Genc, Murat
    The invasive speciesOrosanga japonicawas found at 38 sites in Black Sea coastal zone of Turkey. It was recorded for the first time from the Central Black Sea Region, and for the second time from Western Black Sea Region and in the European part of Turkey. Most localities were close to the Black Sea (<3 km) and situated at altitudes lower than 150 m a.s.l. with the highest records up to 500 m a.s.l. Maximum distance from the sea was in Alemdag, with c. 15 km, and Erenkoy, with c. 10 km. This species is confined in Turkey to the high-rainy and humid coastal zones. Additionally considering cultivated plants,O. japonicawas found on 18 host plant species, of which 15 were previously not known to be used by the species. Nymphs of this univoltine pest were found between May and July, depending on the weather conditions such as rainfall and temperature. Adults emerged between early June and mid-September, with the highest density in the second half of August. Eggs were observed from late August to mid-June.

    Insectum non grata: the harlequin ladybird, Harmonia axyridis (Pallas, 1773) (Coleoptera, Coccinellidae) in Turkey
    (Tubitak Scientific & Technological Research Council Turkey, 2021) Karatas, Ahmet; Karatas, Aysegul; Yavuz, Nizamettin; Ulker, Elif Deniz; Kocak, Ozgur; Akbaba, Burak
    The Harlequin Ladybird, Harmonia axyridis (Pallas, 1773), is native to Eastern Asia but it has been introduced to many countries in Africa, America, and Eurasia. In Turkey, H. axyridis is one of the most fast-spreading invasive alien species. Since the collection of the first specimens in 2010, H. axyridis spread almost all over the country. The species spreads fast in Turkey according to the new records, obtained originally from the field studies and the citizen science data. It was recorded for the first time from 19 of 81 Turkish provinces (Ankara, Antalya, Balikesir, Bolu, Bursa, Istanbul, Izmir, Karaman, Kastamonu, Kirklareli, Kocaeli, Mugla, Rize, Samsun, Sinop, Tokat, Trabzon, Yalova, and Zonguldak) from Aegean, Central and Eastern Black Sea regions. We used the MaxEnt program to predict the current and future potential geographical distribution of this species in Turkey and its surrounding areas. Based on MaxEnt predictions, the majority of this region seems highly suitable for the species.
