Microbial ecological systems of Aphis pomi Deg. digestive tract in territory of the Saratov region was studied. 23 bacteria species belonging to 15 genera was revealed. Curtobacterium flacumfaciens causing diseases at plants was among them.

Выявлены факторы фитопатогенности у бактерий-ассоциантов яблонной (Aphis pomi Deg.), смородиновой (Eriosoma ulmi L.), сливоопыленной (Hyalopterus pruni L.), вишнёвой (Myzus cerasi F.), калиновой (Aphis viburni Scop.) тли. Способностью к мацерации растительных тканей обладали 35% штаммов, изолированных из тли, целлюлолитической активностью – 9% штаммов-ассоциантов.

Trophobiosis with aphids producing honeydew, which is one of the main energetic resources for ants, plays an important role in their life. These are the first data on the trophobiotic as- sociations between ants and aphids in South Zauralye. Investigations were carried out in the most typical biotopes for the region (forest, meadow, steppe and antropogenic biotopes) in 2006–2013. Trophobiotic interactions with aphids are revealed for 17 ant species from two subfamilies: Formicinae (Formica – 7 species, Lasius – 3, Camponotus – 3) and Myrmicinae (Myrmica – 4).
