Abstract
The article discusses the species composition of Heteroptera in the fields of winter and spring rapeseed in the Minsk region of Belarus. A comparison of the species composition of Heteroptera in different seasons in the fields of winter rape was carried out, the dominant species and families of Heteroptera in the fields of winter and spring rape were identified.On the fields of winter rapeseed in summer, the number of species and individuals of Heteroptera is greater than in spring. 41 species were found in the fields of winter rapeseed, they belong to 11 families. Representatives of 9 species were noted among carnivore; their abundance is 23.42 %. The number of collected larvae was 20.25 % of the total number of individuals, of which 14.24 % of larvae belong to the family Miridae. The larvae appear in the fields with the onset of summer. The dominant species is Lygus rugulipennis – 30.7 %. Representatives of 16 species from 7 families of Heteroptera were found in the fields, with the dominant family Miridae – 78.23 %. Representatives of 5 species were noted among carnivore; their abundance is 8.84 %. The number of larvae collected during this period exceeded adults by 1.4 times. The Cymidae family was found only in field No. 3 of winter rape, Rhopalidae was found in the field of spring rape in 2016.
