Список клопов национального парка «Бузулукский бор» (Оренбургская область)

The Buzuluk Forest National Park with an area of 106.79 thousand hectares is the largest isolated pine forest featuring relict landscapes in the north of the steppe zone of the European part of Russia. The east part of the park is mainly located in the Buzuluk district of the Orenburg region. We present a list of heteropteran insects (Insecta: Heteroptera) of the park which includes 101 species from 27 families. The insects were collected by traditional methods: manually, using entomological nets, pitfall traps and/or light traps. We collected insects in Elkhovka village (N52°52’, E52°16’) on 12 July 2003 and 18–19 June 2009; near Partizanskiy settlement (N53°00’, E52°08’) on 18 May and 13–14 July 1992, 23 June – 9 September 2022; in the environs of Berezovka (N53°06’, E52°24’) on 25 April – 1 September 2023. The nominative subspecies of Glaenocorisa propinqua (Fieber, 1860) (family Corixidae) was discovered for the first time in the Urals. Ligyrocoris sylvestris (L.) (family Rhyparochromidae) is reported for the first time for the Orenburg region.

In the Buzuluk forest, 70 Heteroptera species were identified for the first time (a total of 76 species were collected in 1992–2023).
