Bioecological features of cherry fly Rhagoletis cerasi (L. 1758) (Diptera: Tephritidae) development in the Central Non-Chernozem zone of Russia

Cherry fruit fly ( Rhagoletis cerasi (L. 1758) ( Diptera : Tephritidae )) in Central non-Chernozem zone of Russia appeared in the late 1990th-early 2000th, which is associated with global warming and the significant expansion in the acreage of forage plants in this region. Due to ecological plasticity the fly has quickly adapted to local conditions of habitat, and annually flies in a large number. This paper is the first to investigate dates of the flight start, dynamics and duration depending on weather conditions, the periods of egg laying, hatching and feeding of larvae, terms of cocoon formation in soil, and also the peculiarities of the pest diapause under the conditions of Central non-Chernozem Russia. Damage of fruits in cherry varieties of different time of ripening was also assessed. Based on these data, effective methods for monitoring the phytophage are proposed. The studies were carried out in 2016-2018 in the cherry plantations of the All-Russian Horticultural Institute for Breeding, Agrotechnology and Nursery (ARHIBAN, Moscow Province, Leninskii District, 55...
